Product FAQ
Will a 25x25x1 filter fit my system?
If your slot or old filter says 25x25x1, yes — nominal sizes are standardized. Actual size runs about half an inch under nominal so it slides in without jamming.
What does MERV 12 capture?
MERV 12 captures pet dander, mold spores, fine dust and pollen — the sweet spot for homes with pets or mild allergies.
How many packs should I buy?
Shipping is flat-rate and stays the same on 1, 2 or 3 packs — so a year's supply in one order is the cheapest way to buy. Four filters covers a year at the 90-day schedule.
Is this filter made in the USA?
Yes — American-made by our manufacturing partners with electrostatic synthetic media in heavy-duty frames. Built here. Breathe better.
