Not good

Filters are not actual size that package says. The do notfit without being loose and letting air by without going through filter.

Great prices for a solid product. The site was recommended to me by my HVAC tech. The product is better that the ones you find at this large discounted Wearhouse stores.

These filters work great

They arrive on time in a ginormous box and it takes a few years to use them up. I like the convenience of having them on hand and buying in bulk is cost effective.

Second time I've used this

Second time I've used this company. Filters are very efficient. I actually use them more then the 3 months recommended without any issues. These were much cheaper than the local company I'd been using. Fast shipping also. Definitely recommend Filterbuy.

The 4 inch is more narrow than my 3M filter I've been using . "Looser fitting"

Uneven spacing on pleated filters
on February 26, 2025
Posted by: alkesh p.
Company definitely has quality check issues. Ordered 6 pk of 4 wide pleated filters. Pleats are so much closer on ends of filter and middle section is very wide, making filters least efficient for air to pass. I had same issues on my earlier purchase couple years ago. This is my 2nd time buying filters thought 1st was just fluke. I guess no more buying. See the pictures attached.
