Very satisfied. Great customer svce, came through on time frame, even a little earlier than anticipated. Stayed on top of order and most importantly, treated us like we mattered! Didn't have to deal with Ai crap. Refreshing. I kept the number and will put on my phone. Thank you! Linda Paulsen, JAX, FL.

Hopefully Will Fit

We bought these to replace the Filtrate filters. We have typical Florida ceiling vents. The Filtrate are VERY hard to insert. Read these are “smaller” and much easier to insert. We are seniors and do not feel safe climbing up, having to force the Filtrate in. We will begin using the Filterbuy next time we change them in a few months.

The MERV 11 pleated air filter is high quality and catches a large amount of dust.
