I have several different sized vents which require filters. I have not been disappointed with any of them.

Check sizing with lower grade filters. Overall, great company.

We did notice that the filters were slightly smaller this time. We went with MERV 8 vs. our usual order of MERV 11 and they were about a 1/2 inch shorter along the edges. We measured and have previous filters from the same company. We assume their manufacturing changed or, maybe, the MERV 8 are smaller than the actual sizing depicted. Overall, we'd still continue using their company.

I have a bit of an odd shaped Air Filter. They are not available at one of the Big Box stores, But Filterbuy hooked me up with exactly what I needed! Thank you!

I thought I purchased a MERV 12. Filters seem fine and I hope they pull more stuff out of the air
