Material Selection Guide

The HISS20 features premium Type 304 stainless steel construction specifically engineered for extreme temperature applications and highly corrosive environments requiring maximum harsh environment capability beyond galvanized steel’s and aluminum’s limitations. Understanding when stainless steel provides essential performance—compared to cost-effective aluminum or industrial-grade galvanized steel—ensures optimal material selection, maximum service life, and return on investment based on your specific extreme operating environment.

HIS: 304 Stainless Steel Construction (Premium Grade – Harsh Environment)

The Type 304 stainless steel construction features 24-gauge stainless steel frame with 7-ply stainless steel screen wire media and 30-gauge stainless steel face grids, delivering exceptional 900°F continuous temperature rating and maximum corrosion resistance for the most extreme and harsh environment applications. The chromium-nickel alloy composition provides unmatched resistance to corrosion from acidic vapors, alkaline atmospheres, salt spray, chemical exposure, and aggressive industrial environments while maintaining structural integrity at temperatures up to 900°F—575°F higher than galvanized steel and 575°F higher than aluminum. Choose stainless steel when your application involves extreme temperatures exceeding 325°F (foundries, commercial bakeries, industrial drying operations, forge shops), highly corrosive chemical environments with acid or alkaline vapor exposure, salt-laden coastal atmospheres requiring maximum corrosion resistance, operations requiring caustic cleaning agents that would damage alternative materials, or when maximum 5-10 year service life in extraordinarily harsh environments justifies premium investment. Stainless steel excels in foundries, commercial bakery ovens, chemical processing facilities, powder coating curing operations, industrial drying systems, pharmaceutical cleanrooms, electroplating facilities, and extreme corrosion or temperature applications where galvanized steel’s 325°F rating or zinc coating protection proves inadequate. Note that service life for stainless steel is 5-10 years—the same as galvanized steel and aluminum—with stainless steel’s advantage being its ability to achieve this service life in extremely harsh environments rather than extended longevity in standard conditions. The premium cost is justified when extreme temperature or corrosion conditions make alternative materials unsuitable.

HIG: Galvanized Steel Construction (Industrial Grade)

Galvanized steel construction with 325°F temperature rating provides enhanced corrosion resistance and elevated temperature capability at moderate cost, serving most industrial applications effectively. With hot-dip galvanized coating for exceptional rust resistance and 50°F higher temperature rating than aluminum, galvanized steel handles humid environments, moderate corrosion exposure, and temperatures up to 325°F. Consider upgrading to stainless steel (HISS20) when your application involves extreme temperatures exceeding 325°F, highly corrosive chemical environments beyond galvanized steel’s zinc coating protection, salt spray or acidic vapor exposure that would compromise zinc coating, or when caustic cleaning agents are required. For temperatures between 275-325°F and moderate corrosion environments, galvanized steel (HIGS20) provides optimal cost-effectiveness—reserve stainless steel for truly extreme applications where galvanized steel’s capabilities prove inadequate.

HIA: Aluminum Construction (Standard Grade)

Aluminum construction with 275°F temperature rating provides the most cost-effective filtration solution for standard commercial and residential HVAC applications with normal indoor temperatures and dry environments. Aluminum serves the majority of HVAC environments at lowest initial cost with excellent performance in non-extreme conditions. Consider upgrading to stainless steel (HISS20) when your application involves temperatures approaching or exceeding 275°F, highly corrosive environments, chemical vapor exposure, or when previous aluminum filters have shown rapid degradation due to environmental conditions. For extreme applications requiring maximum temperature capability or harsh environment corrosion resistance, stainless steel’s premium cost delivers necessary performance that aluminum cannot provide.

Depth Comparison & Selection Guide

Choosing the optimal filter depth balances dust-holding capacity, cleaning frequency, and system compatibility. The HISS20’s 2″ nominal depth provides the ideal middle ground for most extreme environment applications requiring extended cleaning intervals without the space constraints of deeper 4″ filters.

HISS10: 1″ Nominal Depth (Standard Profile)

The 1″ nominal (7/8″ actual) depth fits the vast majority of HVAC filter tracks with 5-ply media providing 68 g/sq ft dust-holding capacity. Choose 1″ depth when space is limited, when filter track depth is restricted to 1″ nominal, or when your application involves light to moderate particulate loading where frequent cleaning is acceptable. The 1″ profile serves standard extreme temperature applications, chemical processing with light particulate, and situations where the slimmer profile is required for equipment compatibility. Upgrade to 2″ (HISS20) when cleaning frequency becomes burdensome or when particulate loading justifies enhanced capacity.

HISS20: 2″ Nominal Depth (Extended Intervals) – THIS PRODUCT

The 2″ nominal (1-3/4″ actual) depth provides optimal balance between cleaning interval extension and system compatibility with 7-ply media delivering 136 g/sq ft dust-holding capacity—double that of 1″ filters. Choose 2″ depth when you need to reduce maintenance frequency in harsh environments, when particulate loading is moderate to heavy, when system downtime for filter maintenance is costly, or when your filter tracks accommodate 2″ nominal depth. The 2″ profile dramatically extends cleaning intervals in foundries with heavy particulate, commercial bakeries with flour dust accumulation, industrial drying operations with continuous particulate generation, and chemical processing facilities where reducing filter handling in hazardous atmospheres improves safety. The 2″ depth provides the sweet spot for most extreme environment applications—significant interval extension without the depth requirements of 4″ filters. Upgrade to 4″ (HISS40) only when maximum dust-holding capacity and longest possible cleaning intervals justify the deeper profile.

HISS40: 4″ Nominal Depth (Maximum Capacity)

The 4″ nominal (3-3/4″ actual) depth provides maximum dust-holding capacity with 9-ply media delivering 204 g/sq ft capacity—triple that of 1″ filters and 50% more than 2″ filters. Choose 4″ depth when cleaning intervals must be extended to quarterly or even annual frequency, when particulate loading is extremely heavy, when labor costs make frequent maintenance prohibitively expensive, or when remote/difficult filter access justifies maximum capacity. Reserve 4″ depth for extreme environment applications where maintenance reduction is critical: foundries with continuous heavy particulate generation, large commercial bakeries requiring minimal operational disruption, industrial facilities with difficult filter access in extreme conditions, or high-temperature applications where reducing personnel exposure to hazardous areas justifies the deeper profile and higher initial investment.

Construction Features

The HISS20 Custom 2″ Stainless Steel Washable Mesh Filter is engineered with precision manufacturing techniques and premium Type 304 stainless steel materials that ensure every custom-sized unit meets rigorous quality standards for maximum harsh environment durability, extraordinary temperature capability, and exceptional corrosion resistance.

Each custom frame is manufactured to your exact height and width requirements with ±1/8″ tolerance, ensuring precise fit without gaps or binding in your HVAC system’s filter tracks while the stainless steel construction prevents the corrosion-induced dimensional changes and thermal degradation that can compromise alternative materials in extreme applications.

Premium 7-Ply Stainless Steel Media Pack

The filtration media consists of seven layers of corrugated Type 304 stainless steel screen wire arranged in a precision criss-cross weave pattern specifically engineered for 2″ nominal depth applications. This all-stainless 7-ply configuration achieves 43% dust arrestance efficiency while maintaining low airflow resistance of just 0.10″ w.g. at rated airflow. The stainless steel media provides excellent particulate capture while delivering the extraordinary temperature capability and maximum corrosion resistance required for extreme and harsh environment applications. Each layer features expanded mesh construction with carefully engineered strand spacing that captures large particulates through multiple interception stages. The corrugated structure provides increased surface area within the 2″ nominal depth while the criss-cross weave pattern ensures uniform particle distribution across the entire media pack. The enhanced 7-ply configuration—compared to 5-ply in 1″ filters—significantly extends cleaning intervals by providing double the dust-holding capacity (136 g/sq ft vs 68 g/sq ft), reducing maintenance frequency while maintaining optimal airflow performance. This all-stainless engineering approach delivers effective pre-filtration performance with minimal pressure drop, protecting downstream HVAC components without overburdening system blowers—with stainless steel construction ensuring the entire filter assembly maintains structural integrity and filtration performance even when extreme operating conditions would compromise galvanized steel’s zinc coating or cause aluminum degradation.

Corner Drain System

Three strategically positioned corner drain holes facilitate rapid water evacuation following cleaning operations, with typical air-drying times of 60-120 minutes depending on ambient conditions and the enhanced media thickness. The open mesh construction and robust stainless steel frame design enable complete water drainage without trapped moisture in corner joints or frame channels. This drainage system prevents water pooling that could lead to odor development while the Type 304 stainless steel construction ensures the frame resists corrosion even with repeated wet-dry cycles, aggressive caustic cleaning agents, and exposure to corrosive cleaning protocols throughout the filter’s multi-year service life. The stainless steel construction naturally resists rust formation and chemical attack in all environments, maintaining structural integrity and filtration performance through thousands of operational hours at extreme temperatures and repeated cleaning cycles with aggressive agents—delivering consistent dimensional accuracy and reliable filtration in harsh environment conditions where galvanized steel’s zinc coating would be compromised or aluminum would experience severe degradation.

Stainless Steel Face Grid Protection

Both upstream and downstream faces incorporate 30-gauge Type 304 stainless steel protective grids that shield the 7-ply media layers from physical damage during handling, installation, and operation. These stainless steel face grids distribute incoming airflow uniformly across the entire filter surface, preventing concentrated jet streams that could damage the media structure while maintaining the low pressure drop characteristic of 2″ nominal depth filtration. The grid construction provides impact resistance against accidental contact during filter changeouts while the stainless steel composition ensures the face grids resist corrosion and maintain structural integrity in highly corrosive chemical atmospheres, salt-laden environments, and extreme temperature applications where alternative materials would fail. This protective layer ensures the custom-manufactured filter maintains its structural integrity and filtration performance throughout thousands of operational hours at extreme temperatures, repeated cleaning cycles with caustic agents, and continuous exposure to harsh environment conditions—with all-stainless construction delivering maximum durability in demanding industrial and commercial applications that exceed galvanized steel’s and aluminum’s capabilities.

Maintenance & Cleaning Protocol

The HISS20 Custom 2″ Stainless Steel Washable Mesh Filter requires minimal maintenance while delivering 5-10 years of reliable service in the most extreme industrial and commercial environments. Unlike disposable filters that create ongoing frustration finding compatible replacements for custom sizes, this premium stainless steel mesh filter supports repeated cleaning cycles using simple water-based methods, aggressive detergents, and even caustic cleaning agents without corrosion concerns—with Type 304 stainless steel construction ensuring maximum durability throughout years of cleaning cycles in harsh environments.

Cleaning Methods

Four effective cleaning methods accommodate different facility capabilities and contamination levels. Garden hose cleaning provides the simplest approach, using high-pressure nozzle settings to spray both sides of the 7-ply media until water runs clear—typically sufficient for most commercial and light industrial applications (note that the 2″ depth requires more thorough rinsing to ensure complete particulate removal from deeper media layers). Sink or tub soaking works well for moderate to heavy contamination, submerging the filter in warm soapy water for 20-40 minutes before rinsing thoroughly (stainless steel tolerates aggressive detergents, caustic cleaning agents, and corrosive cleaning solutions that would damage galvanized or aluminum construction—longer soak times accommodate the enhanced depth). Commercial dishwashers offer hands-off cleaning for facilities with industrial dishwashing equipment, with stainless steel construction tolerating extreme temperatures and harsh commercial detergents without degradation (verify dishwasher rack capacity accommodates 2″ depth). Pressure washing delivers fast results for heavy contamination typical in extreme-particulate industrial applications, using 1000-1500 PSI with warm water—stainless steel’s robust construction tolerates maximum pressure and aggressive cleaning without corrosion while maintaining structural integrity throughout repeated high-pressure wet cleaning cycles (thoroughly clean both sides and edges to ensure complete particulate removal from 7-ply media). The Type 304 stainless steel frame, media, and face grids withstand repeated washing with caustic agents, acidic cleaners, or alkaline detergents without corrosion or degradation, maintaining structural integrity throughout the filter’s service life while operating continuously at temperatures up to 900°F.

Recommended Cleaning Frequency

Cleaning intervals depend on operating environment and particulate loading rates, with the 2″ depth significantly extending intervals compared to 1″ filters. Light dust environments such as standard commercial applications require cleaning every 6-9 months (double the 1″ filter interval). Moderate industrial applications including manufacturing facilities and commercial operations benefit from quarterly to semi-annual cleaning schedules (compared to monthly for 1″ filters). High-particulate industrial environments with continuous dust generation may need monthly to bi-monthly cleaning to maintain optimal system performance (compared to bi-weekly for 1″ filters). The enhanced dust-holding capacity of 136 g/sq ft—double that of 1″ filters—means the HISS20 can accumulate significantly more particulate before cleaning is required, reducing maintenance frequency and improving operational efficiency. Visual inspection provides the most reliable cleaning indicator—schedule cleaning when the 7-ply screen wire media appears visibly loaded with dust or when system airflow seems reduced. Monitor pressure drop across the filter if instrumentation is available, cleaning when resistance reaches 0.50″ w.g. to maintain energy-efficient system operation. In harsh corrosive environments or applications involving chemical exposure, the Type 304 stainless steel construction maintains its integrity indefinitely—properly maintained stainless steel filters show no corrosion throughout their 5-10 year service life even in the most aggressive chemical and temperature environments.

Handling Considerations for Stainless Steel Construction

Stainless steel filters provide maximum durability with heavier weight compared to galvanized steel and aluminum construction, tolerating aggressive handling, caustic cleaning agents, and extreme pressure washing while still benefiting from proper support during maintenance. Support larger custom sizes from underneath during cleaning and installation to prevent frame stress. The 24-gauge stainless steel frame construction provides exceptional structural rigidity, though the 2″ depth with enhanced media weight makes these filters noticeably heavier than 1″ versions—most custom sizes benefit from two-person handling for safe installation and removal. The Type 304 stainless steel construction tolerates repeated wet-dry cycles, caustic cleaning agents, acidic or alkaline cleaners, and aggressive mechanical cleaning without degradation—maintaining corrosion resistance, structural integrity, and dimensional stability throughout years of service in the most demanding harsh environment applications. Stainless steel construction resists damage from all standard cleaning protocols, making it the optimal choice when aggressive cleaning procedures are required or when chemical exposure demands maximum material durability.

Installation

Installing the HISS20 Custom 2″ Stainless Steel Washable Mesh Filter follows the same straightforward procedures as standard filters, with attention to proper orientation and secure seating to ensure optimal performance from your custom-manufactured premium-grade harsh environment filtration solution.

Pre-Installation Verification

Before installing your custom stainless steel filter, verify the dimensions match your original specifications and that your HVAC system is completely shut down with power disconnected. Inspect the filter housing interior for accumulated dust, debris, or damage that could compromise the seal. The custom-manufactured filter should fit your housing precisely with minimal clearance—if excessive gaps exist, verify you’re installing in the correct location and orientation. Check the condition of existing gaskets or sealing surfaces, replacing worn gaskets before installing your new permanent filter. Clean the filter housing interior thoroughly with a vacuum or damp cloth to ensure optimal sealing surfaces. Locate the airflow direction arrow marked on your new custom filter frame, ensuring you understand proper orientation before installation. Verify that your filter tracks accommodate 2″ nominal depth—the HISS20 requires 2″ nominal filter track depth and will not fit in tracks designed for 1″ filters only. Note the stainless steel construction for documentation in your maintenance records, particularly in extreme environment applications where tracking filter material specifications supports compliance and quality management protocols and where the 900°F temperature rating and maximum corrosion resistance are critical performance requirements.

Installation Steps

With the HVAC system powered off and locked out, open the filter access door or remove the access panel. Carefully remove any existing filter, noting its orientation and airflow direction. Inspect your new HISS20 custom stainless steel filter and locate the airflow direction arrow clearly marked on the frame. The 2″ nominal (1-3/4″ actual) depth provides comfortable handling for smaller sizes, though the stainless steel construction creates heavier weight than galvanized steel or aluminum—most custom sizes benefit from two-person installation for safety. Insert the filter into the housing with the airflow arrow pointing in the correct direction of air movement through your system. Press the filter firmly into place, ensuring all edges seat properly against the gasket or housing walls without forcing. The robust 24-gauge stainless steel frame construction prevents flexing during installation while the custom dimensions create proper fit without excessive gaps around the perimeter. Verify the filter is fully seated in the 2″ nominal depth track—the enhanced depth requires proper track engagement to prevent bypass airflow around the filter. Secure the access door or panel, restore power, and restart system operation.

Post-Installation Verification

After system restart, listen carefully for any unusual sounds such as air whistling or rattling that might indicate improper seating. Verify proper airflow by checking that air velocity at supply registers matches expected performance levels. The low pressure drop of the 2″ nominal filter means system performance should match or exceed previous levels with superior harsh environment filtration capability and extended cleaning intervals. Document the installation date, custom dimensions, 2″ depth specification, and stainless steel construction specification in your maintenance records for future reordering through your online account. The 43% dust arrestance efficiency begins immediately protecting downstream HVAC components from large particulates and debris while the 900°F temperature rating and maximum corrosion resistance ensure filtration performance in extreme environments. Establish a regular inspection schedule based on your specific environmental conditions to monitor dust accumulation and maintain optimal system performance throughout the filter’s 5-10 year service life. In extreme temperature or highly corrosive industrial environments, the Type 304 stainless steel construction provides peace of mind that the filter will maintain structural integrity, dimensional accuracy, and filtration performance throughout years of demanding service in conditions where galvanized steel’s zinc coating would be compromised and aluminum would experience premature failure.

Frequently Asked Questions

How much longer do cleaning intervals last with 2″ vs 1″ filters?

The HISS20 2″ filter with 7-ply media provides 136 g/sq ft dust-holding capacity—exactly double the 68 g/sq ft capacity of HISS10 1″ filters with 5-ply media. In real-world applications, this typically extends cleaning intervals by 80-100%. If you currently clean 1″ filters monthly, upgrading to 2″ filters typically extends intervals to every 2 months. If you clean 1″ filters quarterly, 2″ filters often extend to semi-annual cleaning. The exact interval depends on your specific particulate loading, but the doubled dust-holding capacity consistently reduces maintenance frequency by approximately half, significantly reducing labor costs and operational disruptions in harsh environment applications where filter access may be difficult or time-consuming.

Will 2″ filters fit in my current filter tracks?

No, the HISS20 requires filter tracks designed for 2″ nominal depth filters. The 2″ nominal (1-3/4″ actual) filter will not fit in tracks designed for 1″ nominal (7/8″ actual) filters. Before ordering, verify your HVAC system’s filter housing accommodates 2″ nominal depth. If your current system uses 1″ filters, upgrading to 2″ depth requires either modifying filter tracks or replacing filter housings—contact your HVAC contractor to assess feasibility. Many commercial and industrial HVAC systems offer adjustable or multi-depth filter tracks that can accommodate different depths. If track modification isn’t feasible, the HISS10 1″ stainless steel filter provides the same 900°F rating and maximum corrosion resistance in the slimmer profile that fits your existing tracks.

When should I choose 2″ instead of 1″ or 4″ stainless steel filters?

Choose 2″ (HISS20) when you need extended cleaning intervals beyond 1″ capacity but your system cannot accommodate 4″ depth, when maintenance frequency reduction justifies moderate upgrade cost, or when your tracks accommodate 2″ nominal depth. The 2″ depth provides the optimal balance for most harsh environment applications—significantly extended intervals (double 1″ capacity) without the space requirements, deeper profile, or higher cost of 4″ filters. Choose 1″ (HISS10) when space is limited or light particulate loading doesn’t justify enhanced capacity. Choose 4″ (HISS40) only when maximum capacity is critical: extremely heavy particulate loading, quarterly or annual cleaning requirements, or difficult filter access in extreme conditions where maintenance frequency reduction justifies premium investment.

Does stainless steel last longer than galvanized steel or aluminum?

Service life for properly maintained washable mesh filters is 5-10 years regardless of material—aluminum, galvanized steel, and stainless steel all achieve this lifespan with proper maintenance. The difference is WHERE each material achieves this service life. Aluminum achieves 5-10 years in standard environments below 275°F with low corrosion. Galvanized steel achieves 5-10 years in industrial environments up to 325°F with moderate corrosion. Stainless steel achieves 5-10 years in EXTREME environments up to 900°F with maximum corrosion exposure. Stainless steel’s advantage is its ability to deliver full service life in harsh environments where alternative materials would fail prematurely—not extended longevity in standard conditions. Choose stainless steel based on your extreme operating environment, not for longer service life.

Can I use 2″ stainless steel filters in multi-stage filtration systems?

Yes, the HISS20 excels in multi-stage harsh environment filtration systems. Use as first-stage pre-filter before higher-efficiency secondary filters to extend secondary filter life while maintaining extreme temperature capability throughout the system. Use as second-stage filter after 1″ stainless steel pre-filter (HISS10) for enhanced particle capture with extended cleaning intervals. The 2″ depth provides excellent balance in multi-stage systems—sufficient capacity to significantly extend intervals without the cost and space requirements of 4″ filters. In extreme environment multi-stage systems, consistent stainless steel construction throughout all stages ensures temperature capability and corrosion resistance isn’t compromised at any point in the filtration chain.

How does weight compare to galvanized steel and aluminum 2″ filters?

Stainless steel filters are heavier than equivalent galvanized steel or aluminum filters due to stainless steel’s higher material density. A custom HISS20 2″ stainless steel filter typically weighs 15-20% more than the equivalent HIGS20 2″ galvanized steel filter, and 35-50% more than an equivalent HIAS20 2″ aluminum filter. The exact weight varies by custom dimensions. Larger custom sizes (20×25″ and above) benefit from two-person handling during installation and removal. The enhanced weight reflects the premium Type 304 stainless steel construction that provides 900°F temperature capability, maximum corrosion resistance, and caustic cleaning tolerance—performance characteristics that justify the modest weight increase for extreme environment applications.

Can I order the same custom dimensions in different materials and depths?

Yes, absolutely. Once you’ve specified your custom dimensions for the HISS20 stainless steel filter, you can order the same size in galvanized steel (HIGS20) for industrial-grade applications, aluminum (HIAS20) for cost-effective standard applications, or different depths (HISS10 for 1″, HISS40 for 4″) in the same stainless steel material. Many facility managers maintain inventory in multiple materials and depths for different zones—aluminum for standard areas, galvanized steel for industrial zones, stainless steel 1″ for space-constrained extreme temperature areas, stainless steel 2″ for general extreme environment applications, stainless steel 4″ for maximum capacity requirements. Your custom dimensions are saved in your account for easy reordering in any material/depth combination.

How long does custom stainless steel filter manufacturing take?

Custom stainless steel filter manufacturing typically requires 5-10 business days from order confirmation to shipment, though production schedules may vary based on current order volume. Stainless steel production may add 1-2 days to lead time compared to aluminum or galvanized steel due to specialized stainless steel processing. The 2″ depth doesn’t significantly affect production time compared to 1″ or 4″ depths. Rush production is available for critical applications. We recommend ordering before your existing filter reaches end-of-service to ensure continuous filtration coverage, particularly in extreme environment applications where extended lead times might otherwise create operational challenges in harsh condition environments.

Why Choose the HISS20 Custom 2″ Stainless Steel Washable Mesh Filter?

Choosing the HISS20 Custom 2″ Stainless Steel Washable Mesh Filter eliminates the frustration and expense of searching for compatible replacement filters for HVAC systems with discontinued or non-standard dimensions while providing maximum harsh environment capability, exceptional corrosion resistance, extraordinary 900°F temperature capability, and dramatically extended cleaning intervals that galvanized steel and aluminum construction cannot match. Whether you’re maintaining foundry ventilation systems operating above 325°F, supporting chemical processing facilities with highly corrosive vapor atmospheres, servicing commercial bakery ovens requiring continuous extreme temperature capability with reduced maintenance frequency, or managing industrial drying operations where standard materials degrade prematurely and where cleaning frequency impacts operational efficiency, this made-to-order premium stainless steel solution provides permanent filtration precisely matched to your unique dimensional requirements and extreme operating conditions. The custom manufacturing process ensures perfect dimensional fit while Type 304 stainless steel construction ensures optimal performance and maximum service life in harsh environments where alternative materials prove inadequate—all with extended cleaning intervals that reduce maintenance burden by approximately half compared to 1″ filters.

Built to the same rigorous quality standards as our stock HIS Series products, this custom filter features precision-engineered 7-ply all-stainless media construction and UL 900 Class 1 certification with exceptional 900°F continuous temperature rating—575°F higher than galvanized steel’s 325°F limitation and 625°F higher than aluminum’s 275°F constraint. The industry-standard 2″ nominal (1-3/4″ actual) depth profile provides optimal balance between cleaning interval extension and system compatibility, delivering 136 g/sq ft dust-holding capacity—exactly double that of 1″ filters—while maintaining excellent airflow performance. Made in USA with premium 24-gauge Type 304 stainless steel frames, all-stainless media, and 30-gauge stainless steel face grids, each custom filter is manufactured to your exact specifications with ±1/8″ tolerance, ensuring precise fit and optimal performance throughout its 5-10 year service life in the most extreme industrial and commercial applications.

The permanent washable construction delivers exceptional long-term value compared to disposable alternatives—especially critical for custom sizes where finding compatible replacements creates ongoing frustration and expense and where stainless steel’s maximum harsh environment capability extends service life in extreme conditions where galvanized steel’s zinc coating would be compromised and aluminum would experience rapid failure. The enhanced 2″ depth with double the dust-holding capacity of 1″ filters reduces cleaning frequency by approximately half, significantly lowering maintenance labor costs and operational disruptions in harsh environment applications where filter access may be difficult, time-consuming, or require system shutdown during peak production periods. Once you’ve placed your initial custom order, reordering identical stainless steel filters is effortless through your online account, eliminating the need to re-measure or re-specify dimensions for future purchases. The 43% dust arrestance efficiency protects downstream HVAC components while the low 0.10″ pressure drop maintains optimal system efficiency. Simple water-based cleaning every few months—or aggressive caustic cleaning when required—restores peak performance, with Type 304 stainless steel construction supporting repeated cleaning cycles with harsh chemicals throughout the filter’s multi-year service life without corrosion or degradation.

Facility managers, property owners, HVAC contractors, and industrial maintenance professionals choose the HISS20 when standard filters cannot solve their combined dimensional and extreme environment filtration challenges, when operating conditions demand maximum harsh environment capability exceeding galvanized steel’s and aluminum’s limitations, and when reducing maintenance frequency delivers measurable operational value.
