Trane Perfect Fit BAYFTAH23M2 23.5x21x5 Air Filter

I received the filters and installed one right away. It was exactly like the one we replaced. It was 1/2 the cost of the one we got at the dealer last year. Will have one to replace it next year. Will reorder in two years.

Looks good. Arrived OK. Keeping it as a spare, will order another when changed. How long should this size filter be used before replacement? Thanks.

I bought these to replace the ones I previously purchased from Atomic about a year ago. I haven't even opened this package yet, but the ones they replaced were perfect. My A/C uses a very unique size and Atomic (fortunately) has them. I buy them from Atomic rather than pay 3 or 4 times as much to get them from my A/C service. Totally satisfied.
