Corrosion Resistant
This page lists all 9 Corrosion Resistant replacement filters available from Metal Air Filters — precision-manufactured washable aluminum mesh filters engineered as direct OEM replacements for Carrier commercial HVAC equipment. All filters on this page are HI Series and HIA Series products manufactured by American Metal Filter Company (AMFCO) with .030" extruded aluminum alloy frames, corrugated aluminum mesh media, UL 900 Class 1 certification, and a 275°F maximum operating temperature rating.
Each filter is a permanent washable replacement — clean and reuse for 5–10 years rather than replacing disposable filters every 30–90 days. AMFCO’s aluminum mesh construction provides 43% average dust arrestance per ASHRAE 52.1, making these filters ideal pre-filters in multi-stage Carrier commercial HVAC systems protecting downstream MERV 8 through HEPA filtration stages in rooftop units, air handlers, and split systems.

Key Benefits of Corrosion Resistant Washable Aluminum Mesh Filters
- Custom Sizing for Any Equipment: Manufactured to your exact length and width specifications, eliminating fitment issues and providing direct OEM replacements for discontinued or hard-to-find filter sizes.
- Three Material Options: Choose aluminum for cost-effective standard applications (275°F), galvanized steel for enhanced durability (325°F), or 304 stainless steel for extreme environments and harsh conditions (900°F).
- Industry-Standard 2″ Depth: 2-inch nominal (1-3/4″ actual) depth fits equipment designed for standard 2″ filter tracks, providing compatibility with existing housings while offering custom face dimensions.
- Superior Dust-Holding Capacity: 7-ply media construction delivers 97 g/sq ft dust-holding capacity—42% more than 1″ filters—extending cleaning intervals and reducing maintenance frequency.
- Permanent Washable Design: Eliminates recurring filter replacement costs through 5-10 years of reliable service, with simple water washing restoring like-new filtration efficiency.
- Effortless Reordering: Your custom dimensions are permanently saved in your online account after the first order, enabling quick reorders without re-measuring or re-entering specifications.

Commercial & Industrial Applications
Carrier commercial HVAC equipment is deployed across a wide range of commercial, institutional, and industrial building types. The following applications represent the primary use cases for Corrosion Resistant permanent washable aluminum mesh filters.
Discontinued and Legacy Equipment
The HIAS20 provides the perfect solution when OEM filters for older HVAC systems and industrial equipment are no longer available from the original manufacturer. Many legacy air handlers, fan coil units, and process air systems require 2-inch depth filters in non-standard face dimensions that have been discontinued or are prohibitively expensive through OEM channels. By ordering custom HIAS20 filters manufactured to your exact specifications, you maintain optimal filtration performance without costly equipment replacement or modification. Your custom dimensions are saved for easy reordering, ensuring consistent fitment across multiple replacement cycles. The 5-10 year washable design reduces total cost of ownership compared to disposable alternatives, even for equipment with odd or obsolete filter sizes.
European and International Equipment
European HVAC manufacturers and international equipment suppliers often specify metric filter dimensions and non-standard depth combinations that don’t align with U.S. standard sizes. The HIAS20 accommodates these unique dimensional requirements by manufacturing filters to your exact metric or imperial specifications, eliminating forced-fit installations and air bypass issues. Whether your equipment requires 500mm × 600mm dimensions, unusual aspect ratios, or metric depths with imperial face dimensions, the HIAS20 configurator converts your measurements into a precision-manufactured filter that fits properly the first time. The three material options ensure compatibility with European temperature specifications and environmental requirements across diverse climates and industrial processes.
High-Temperature Industrial Processes
Industrial operations involving elevated temperatures demand filtration solutions that maintain structural integrity and performance under thermal stress. The HIAS20’s three material options provide temperature flexibility from 275°F (aluminum) to 900°F (304 stainless steel), accommodating pre-filters for industrial ovens, dryers, heat treating furnaces, powder coating booths, and high-temperature process air systems. The 7-ply media construction maintains mechanical strength and filtration efficiency at elevated temperatures, while material-matched rivets and frame construction prevent thermal expansion mismatches that cause frame warping or media separation. For applications between 275°F and 325°F, the galvanized option provides cost-effective performance. For sustained temperatures above 325°F or intermittent spikes approaching 900°F, the 304 stainless steel construction is essential.
Corrosive and Moisture-Rich Environments
Facilities exposed to corrosive chemicals, salt spray, high humidity, or aggressive cleaning protocols require filtration materials that resist degradation from environmental exposure. The HIAS20’s 304 stainless steel option (HIS) delivers maximum corrosion resistance for chemical processing plants, coastal industrial facilities, marine applications, commercial kitchens, car wash installations, food processing plants, and pharmaceutical cleanrooms requiring frequent washdown with caustic agents. Unlike aluminum or galvanized filters that deteriorate when exposed to acids, bases, chlorides, or salt spray, the 304 stainless construction maintains structural integrity and filtration performance throughout the filter’s 5-10 year service life. For moderate moisture exposure without corrosive chemicals, the galvanized option provides adequate protection at lower cost than stainless steel.

Frequently Asked Questions
How do I choose between aluminum, galvanized, or stainless steel for my HIAS20?
Select based on operating temperature and environment. Choose aluminum for cost-effective performance up to 275°F. Choose galvanized steel for enhanced durability up to 325°F. Choose 304 stainless steel for harsh conditions up to 900°F. All materials offer 5-10 years service life.
What is the difference between 2″ nominal and 1-3/4″ actual depth?
The 2″ nominal dimension is industry-standard sizing for this thickness. The 1-3/4″ actual is the precise manufactured depth, allowing proper fitment in filter tracks designed for 2-inch filters.
Can I order different materials for the same dimensions?
Yes. Once you order in specific dimensions, your account saves those dimensions. You can reorder in the same or different materials (HIA, HIG, or HIS) while maintaining same length and width.
How does the 2″ filter compare to the 1″ filter in dust-holding capacity?
The HIAS20’s 7-ply construction provides 97 g/sq ft dust-holding capacity vs. 68 g/sq ft for the 1″ HIAS10—a 42% improvement that extends cleaning intervals.
Does material selection affect filtration efficiency?
No. All three materials deliver identical 43% dust arrestance and 97 g/sq ft dust-holding capacity. Material differences are temperature rating, corrosion resistance, and frame weight—not filtration performance.
