I always purchase Filterbuy filters because they do make a difference. My family has allergies and these filters help so much.

Works great, fits like it should. . . Strangely excited about changing it in a few months to see what all it filtered for us.

This is the first time

This is the first time that I am using A/C filters from Filterbuy. Although they were slightly shorter (disclosed on their website) than my previous filters, they actually fit better at my vent openings. I used to have to cut the corners off of the previous brands of filters that I have used in the past because they were much too tight fitting. I think I will be using Filterbuy filters from now on.

30" filter was a 1/2" inch short
on September 17, 2025
Posted by: Winslow S.
I purchased a 24" x 1" and a 30" x 1" filter, both stating they were 8" tall; the 30" came in a full 1/2" short, at 7. 5, where as the 24 came in at a full 8". How do you account for that? Now there's a gap in the filter and debris can get in the fan; not good enough
