Amazing customer experience Amazing customer experience. They shipped our product and it arrived in a very timely fashion. We realized that we had ordered the wrong product - we called them, and their return process was so simple. Exceptionally good company to work with!

Never again Ordered and when they arrived they did not fit. Was given the same song and dance another reviewer was, that it is my fault that I did not measure and that not making the filters to the correct size “is industry standard” Be warned 1) Any returns require YOU THE CUSTOMER to pay shipping 2)They record all calls but never inform you of that 3)They are unable to take responsibility or blame for even the smallest thing they do wrong NEVER BUY FROM THEM!

A trusted brand A trusted brand, especially during a pandemic! Made right here in 🇺🇸. I love that I can order online and click and reorder, right through my email reminder! Very satisfied customer😍 Thank you!!!

Smaller Than Standard 20x20x4 Filter Size The positive: good price and fast shipping. The negative: Their 20x20x4 Filters are much smaller than 20x20x4 filters made by the name brands. As a result, they don't fit properly in my air handler. Rather than pay to send them back, I am going to glue a cardboard frame to them to make them fit properly. In addition, the manufacturing quality of the filters are suspect. Name brands have spacers that keep the pleats evenly spaced. These Filterbuy filter pleats are not evenly spaced and the pleats are bunched up near the edges. They are also glued into place and cannot be adjusted. Save yourself the hassle and get name brand filters or be sure to verify that the ACTUAL size of the filter will fit your application.

FilerBuy A/C filters; excellent result… The FilerBuy A/C filters did an excellent job over the past year in trapping the particles in our air. We change the filters every 3 months throughout the year in our Florida home and we will be ordering this next year's supply today.
