They seem to do what filters are meant to do correctly. I change them every 3 months, and also, I change a continent sponge every 6 months

Special Sizing
on May 30, 2026
Posted by: Customer
We have a tune up on the heat and air every six months. The company charges for one filter, of lesser quality, that we pay for the four Merv 8 pleated air filters. One return is an odd size ( I'm sure that is because we have to use the company filters ) and Filter Buy made the special size for our use.

I have a hard to find filter size. No worry just order a few days later they show up.
