Sizing Guide & Compatibility Information

Selecting the correct dimensions ensures proper fit and optimal performance. Our custom manufacturing capabilities provide filters in any size you need.

How to Measure for Correct Size

Step 1: Remove Existing Filter

Take out your current filter to measure it directly. If no filter is installed, measure the pre-filter housing opening.

Step 2: Measure Width, Height, and Depth

• Width: Measure horizontal dimension (left to right)
• Height: Measure vertical dimension (top to bottom)
• Depth: Measure thickness – confirm you need 1/2 inch (not 1 inch or 2 inches)
• Measure Twice: Verify measurements for accuracy before ordering

Step 3: Account for Nominal vs Actual Sizing

Like other filters, 1/2-inch filters use nominal sizing. A filter listed as 10x10x0.5 has actual dimensions of approximately 9.75″ x 9.75″ x 0.4375″-0.5″. This slight undersizing allows the pre-filter to fit into housing tracks.

Common Range Hood Filter Sizes

Range hood filters (the most common application for 1/2-inch filters) come in various sizes:

• Small Range Hoods: 8×8, 10×10, 10×11.5, 10×12
• Medium Range Hoods: 11.5×11.5, 11.5×17, 12×12, 12×18
• Large Range Hoods: 16×16, 18×18, 20×20, 11.5×23
• Commercial Range Hoods: Various sizes including 20×20, 20×25, and custom large formats
• Multi-Filter Hoods: Some hoods use 2-4 smaller filters side-by-side

Custom Sizing Options

• Size Range: Minimum 6×6 inches up to 48×48 inches in 1/2-inch thickness
• Fractional Dimensions: We accommodate fractional dimensions (e.g., 11.5″ x 17.375″ x 0.5″)
• Non-Square Shapes: Any length/width combination within our size range
• Multiple Quantity Discounts: Order multiple filters for volume pricing
• Matching Sets: Order multiple identical filters for multi-filter range hoods

Verifying Fit Before Installation

• Check Depth Clearance: Ensure housing has at least 1/2-inch depth (preferably 5/8-inch for easy installation)
• Test Slide-In: Filter should slide smoothly into housing with minimal resistance
• Verify Sealing: When installed, no visible gaps should exist around filter perimeter
• Test Retention: If housing uses clips or springs, verify they engage properly

Thickness Selection Guide

Choose 1/2-inch thickness when:

• Your housing has less than 3/4-inch depth clearance
• Original equipment specified 1/2-inch filters
• Space constraints prevent using thicker filters
• Application is range hood, electronics cooling, or compact equipment
• You need lighter weight filters for easier handling

Consider 1-inch thickness instead if:

• Housing has 1-inch or greater depth
• Application requires maximum dust-holding capacity
• Extended cleaning intervals are desired

Frequently Asked Questions

What is the difference between 1/2-inch and 1-inch aluminum mesh pre-filters?

The primary difference is thickness: 1/2-inch filters are approximately half the depth of 1-inch filters. The 1/2-inch version fits shallow filter housings common in range hoods, compact HVAC equipment, and space-constrained applications. While both provide similar filtration efficiency per layer, 1-inch filters may have more mesh layers and slightly greater dust-holding capacity. For most range hood and compact equipment applications, 1/2-inch filters perform excellently. Choose based on your housing depth requirement.

Can I use this pre-filter as a replacement range filter for my commercial kitchen hood?

Yes, this aluminum mesh pre-filter is an excellent replacement range filter for commercial kitchen range hoods. The 1/2-inch thickness matches most commercial hood filter requirements, the aluminum construction withstands grease and high temperatures up to 180°F, and the washable design saves money compared to disposable grease filters. Simply measure your current filter dimensions and order the matching size. Many restaurants use these filters and clean them weekly or bi-weekly depending on cooking volume.

How often should I clean this pre-filter in my range hood?

For residential range hoods, clean every 30-60 days depending on cooking frequency. If you cook frequently or prepare greasy foods (frying, stir-fry), clean every 2-4 weeks. For commercial kitchen range hoods, clean weekly to monthly depending on kitchen volume. A good rule of thumb: when you can see significant grease buildup or notice reduced hood performance, it’s time to clean. Regular cleaning prevents grease from becoming baked-on and difficult to remove.

Can I put this aluminum filter in my dishwasher?

Yes, dishwasher cleaning is one of the easiest methods for aluminum mesh pre-filters. Place the pre-filter in your dishwasher (ensure it fits without forcing), run a heavy-duty or pots/pans cycle with regular dishwasher detergent, and skip the heated dry. The slim 1/2-inch profile makes these filters easy to fit in most dishwashers. Air dry completely before reinstalling. This method works especially well for range hood pre-filters with grease buildup.

What sizes are available for this 1/2-inch aluminum mesh pre-filter?

We manufacture custom sizes from 6×6 inches up to 48×48 inches in any dimensional combination. Common range hood sizes like 10×10, 11.5×11.5, 11.5×17, 12×12, 16×16, and 18×18 are available. We also accommodate fractional dimensions (e.g., 11.5″ x 17.375″) for exact-fit applications. Simply provide your required dimensions when ordering, and we’ll manufacture the pre-filter to your exact specifications.

Is this pre-filter compatible with filter compatible with my existing range hood?

This filter compatible design works with any range hood, HVAC equipment, or ventilation system that uses 1/2-inch thick filters. To verify compatibility: measure your existing filter’s thickness (should be approximately 1/2 inch), measure the width and height, and order matching dimensions. The filter works with spring clips, slide-in tracks, or any standard retention method. If you’re replacing a disposable filter, measure the housing opening to determine the size needed.

How long will this washable pre-filter last?

With proper maintenance and regular cleaning, expect 5-10 years or more of reliable service life. The durable aluminum construction resists corrosion, warping, and degradation. Replacement becomes necessary only when the frame suffers physical damage, mesh tears or separates from the frame, or the pre-filter no longer fits securely. Many customers report 10+ years of use with range hood pre-filters. The key to longevity is regular cleaning to prevent permanent grease buildup.

What’s the best way to remove heavy grease buildup?

For heavy grease accumulation, use the soaking method: Fill a sink with very hot water and commercial degreaser or strong dish soap. Submerge the pre-filter and let soak 30-60 minutes (or overnight for extreme buildup). The hot water and degreaser break down the grease. After soaking, use a soft brush to scrub away loosened grease, rinse thoroughly, and air dry. For regular maintenance, don’t let grease build up to extreme levels – clean more frequently instead.

Can I use this pre-filter in a high-temperature application?

Yes, aluminum mesh pre-filters tolerate temperatures up to 180°F (204°C) without degradation, making them ideal for range hood applications where they’re exposed to cooking heat and steam. The all-aluminum construction (no plastic, adhesives, or synthetic materials) maintains structural integrity at elevated temperatures. This is one reason why aluminum filters are preferred over disposable filters in range hood applications.

Will this pre-filter work in my computer server room or data center?

Yes, the slim 1/2-inch profile makes this pre-filter excellent for electronics cooling applications where space is limited. The aluminum mesh effectively captures dust and airborne particles while maintaining good airflow for equipment cooling. For server rooms and data centers, clean every 90-180 days depending on dust levels. The washable design is more economical and environmentally friendly than disposable filters for facilities with multiple cooling units.

Does this pre-filter remove cooking odors?

No, aluminum mesh pre-filters primarily capture grease particles and airborne contaminants but do not remove odors, smoke, or gases. For odor removal, your range hood should vent to the outdoors, or you can add an activated carbon filter downstream of the aluminum mesh pre-filter. The mesh pre-filter serves as an excellent grease pre-filter that protects carbon filters from grease contamination, extending their effectiveness.

Is this pre-filter fire-safe for range hood applications?

Yes, aluminum is non-combustible and maintains structural integrity even if exposed to flame. This is a critical safety feature for range hood pre-filters. While the pre-filter captures grease (which is flammable), the aluminum construction won’t ignite or contribute to fire spread. Regular cleaning is still essential – accumulated grease in ductwork behind the pre-filter creates fire hazards regardless of filter material.

Can I buy a replacement aluminum filter for my old range hood model?

Yes, our custom manufacturing capability means we can create replacement aluminum filters for virtually any range hood including obsolete or discontinued models. Simply measure your existing filter or filter housing opening, provide those dimensions when ordering, and we’ll manufacture a filter that fits perfectly. This is often more cost-effective than searching for OEM replacement filters for older equipment.

What if my filter gets damaged or doesn’t fit?

We stand behind our manufacturing quality. If you receive a filter with incorrect dimensions or manufacturing defects, contact our customer service team immediately. We’ll work with you to verify measurements and provide a replacement filter if the error was on our end. To avoid sizing issues, carefully measure your existing filter or housing opening before ordering, and contact us if you have any questions about sizing.

Do you offer volume discounts for commercial kitchen applications?

Yes, we provide volume discounts for multiple filter orders. This is particularly beneficial for restaurant chains, commercial kitchen operators, or facility managers with multiple range hoods. Contact our sales team with your quantity requirements and dimensions for a custom quote. Bulk orders receive priority manufacturing and may qualify for additional shipping discounts. Many commercial customers order spare filters to rotate during cleaning cycles.
