Haven't got replacement yet

I got my filters really quick but they were much smaller than the one I had. The product was 16x 25 x 4. The filters I took out of my ac were also printed that size. The lesson learned is forget what it says on your filter. Look at the filter edge till you find actual size. Big difference. Return was easy. Just waiting on replacements b

Efficient filter

I purchased these filters because they will remove most of the dust and pollen from the air for my air-conditioning system. Since I live in the northeast, I only use the system during the summer months and really only go through one filter a year. I have the next six years covered.
They were a good price.

We’ve been using the MERV 13 filters for a couple of years now, and have been very pleased with the results. Worth the slight additional cost.

Very misleading sizes
on August 28, 2026
Posted by: Customer
Filterbuy products are not what they claim. Just went to replace my filter with a new one from Filterbuy brand filters and it’s a half inch smaller in every dimension. Filter doesn’t fit the slot well and wobbles around.

We the autoship feature, it makes it easy to remember to replace the filters in a timely fashion. Pay attention to the actual dimensions provided in the product descriptions, they run a bit smaller!
