9 Gauge Steel
Internal 9 Gauge steel reinforces and supports the filter, keeping it strong and stable in your unit or ductwork.
Graduated Density Media
Our filters’ industry-leading graduated density synthetic media captures dirt particles by size and lasts up to 9 months.
Self-Sealing
Our self-sealing filter cleans 100% of your air, allowing for zero blow-by. This keeps your unit clean and allows it to run more efficiently.
No Cardboard
Our filters do not contain cardboard, which means microorganisms can’t grow on the filter and pollute your indoor air.
