Good Product and Company

Filters are well made and easily installed. We use them in a 3 zone system, all different size returns. Filterbuy can supply all sizes, with the MERV rating of our choice and reminds me when to reorder. We were sent one package thar was the incorrect size. One phone call, the new ones were on the way and the old ones were donated to charity, at the company's cost. That is service!

Where the filters appear to be working okay, they dont clean the air as well as other brands. I am not confident that a MERV 13 is doing its job.

Central AC filter
on August 9, 2022

I bought the MERV filter to use in the ceiling air intake of my central AC system. It works fine. Before replacing the plastic mesh filter that was there, I thought the MERV filter might slow the air flow. It didn't. The cool air comes through as strong as ever, and cleaner.

Love these filters.

I have a couple dogs & terrazzo floors so I change my filters every 30 days. I started using these filters last year when I first purchased this home and added central air. A year later it still smells fresh walking in Im sure its due to good filters helping me to keep it clean.
