Capivative-Aire MUA And Supply Fan Filter 20x25x1 (Two Pack)
Best for large commercial kitchens and high-capacity supply fans. Features an aluminum frame with a media that captures dirt and dust from the air stream for make-up air and heater intakes. Size is 20” x 25” x 1”, supplied as a two-pack. Rigid construction and corrosion resistance help extend service life in busy environments.
Who it’s for: facilities needing robust filtration for big kitchen hoods and MUA units. Why selected: designed specifically for commercial kitchen supply fans and make-up air systems, improving air cleanliness and reducing debris intake. Caution: larger footprint may require precise mounting space; confirm compatibility with existing housings.
Captaive-Aire MUA Filter 16x25x1 (Two Pack)
Best for mid-sized make-up air units and supply fans. Aluminum frame with a robust media layer that traps dirt and dust from the air stream. Size 16” x 25” x 1” (two-pack) offers a practical balance of filtration area and cabinet fit in many restaurant or commercial kitchen setups.
Who it’s for: restaurants or commercial spaces with standard hood widths. Why selected: compact yet effective for typical MUA in smaller to mid-range installations. Caution: shallower depth means slightly less filtration area than deeper models; verify driveway or hood clearance.
Air Filter Factory Aluminum Filter S97021045 Replacement — 2-Pack
Best for residential to light commercial ventilation systems needing a versatile aluminum mesh. Replacement set includes two filters designed to fit models S97021045, 97021045, AP6872391, and PS16529652. Aluminum construction with a multi-layer mesh design ensures dependable filtration and long-lasting performance. Overlapping joints reduce snagging and improve handling.

Captaive-Aire MUA Filter 16x25x2 (Two Pack)
Best for deeper filtration needs in drier or dustier environments. Aluminum frame and media capture dirt from air streams for make-up air and heater intakes. Size 16” x 25” x 2” (two-pack) provides more filtration media than the 1″ variant, aiding longer intervals between changes.
Who it’s for: facilities with larger dust loads or longer duct runs. Why selected: increased thickness offers improved filtration capacity. Caution: deeper filters may require more cabinet clearance; check mounting space before purchase.
Captaive-Aire MUA Filter 16x20x1 (Two Pack)
Best for compact installations where space is tight but filtration remains necessary. The 16” x 20” x 1” aluminum frame with mesh media catches dirt and dust in the air stream for make-up air and related intake fans. Sold as a two-pack for easy replacement cycles.
Who it’s for: smaller kitchens, compact hoods, or retrofit projects with limited cabinet depth. Why selected: tight fit without sacrificing standard filtration performance. Caution: ensure the 1″ depth aligns with existing filter slots to avoid binding.
Buying Guide: Key Considerations For Filters In Supply And Intake Fans
- Filtration depth and airflow: Deeper filters (2″) offer more filtration area but require more space. Choose based on dust load and available cabinet depth.
- Material and corrosion resistance: Aluminum frames resist kitchen humidity and HVI environments; stainless steel is another option in harsh environments.
- Size compatibility: Confirm exact width, height, and depth of the filter slot (e.g., 16x25x1, 20x25x1) to prevent fit issues.
- Number of filters: Pack quantity affects replacement cycles. Two-packs are convenient for quick swaps.
- Mounting and handling: Look for overlapping joints and solid frame construction to reduce snagging during installation and maintenance.
- Intended use: Some filters are marketed for commercial kitchen MUA, others for residential fresh-air fans; ensure the model matches your system.
FAQ
- What is MUA in ventilation systems?
MUA stands for Make-Up Air, which is the process of replacing air that is exhausted from a space to maintain balanced pressure and proper ventilation.
- Are aluminum mesh filters suitable for kitchen hoods?
Yes, aluminum mesh filters are commonly used for kitchen air intakes and make-up air units due to corrosion resistance and effective particulate capture.
- How do I know which size to buy?
Measure the existing filter slot: width x height x depth. Use the matching size (for example, 16x25x1) to ensure a proper fit.
- Do these filters require special maintenance?
Regular replacement according to the dust load and system design is recommended. Check for bent frames or torn media during inspections.
- Can I use these filters in residential ventilation?
Some models are compatible with residential systems, especially the 2-pack aluminum mesh filters; verify compatibility with your unit’s model number.
- Why pick a 2″ filter over a 1″ one?
A 2″ filter provides more filtration area and can capture finer debris in dusty environments, but you must ensure there is enough space in the filter slot.
