Where Do You Buy Your AC Filters From?

Amazon

Best place is a hvac wholesale house. Most will sale filters to home owners an usually lot cheap than chain stores

Home Depot, or the local grocery. Just make sure they're a good make. The washable, reusable type don't really do a good job. They let too much stuff through.

Amazon now, specialty filters that used to be only available through dealer or manufacture. Now can be found in box stores and such but original manufacturer can be found on amazon cheaper. Cheaper then some of the knockoffs available now that don't quite do the job.

The same grocery store where I shop for food.

Amazon for the central heating and AC.

I use FRAM filters.

Wally World. I have a 12 x 24 filter frame, and they may be available commercially, but for home use, you cannot find anything better than using two 12 x 12's. So I started buying the reuseable, washable, generic cut to fit filters for about $4 each. They last longer and are reuseable after a good rinse and dry. Or cheap enough to just replace.
