Great quality and perfect size!

Good price and got them fast.

I was glad to find a replacement filter for my air purifier. It was super easy to install and works great.

I have used my germ guardian for years and these filter replacements are great! There isn’t any off gassing or weird smell like some other filters I have used in the past. It is easy to change out and I have noticed an improvement in my allergies. I actually miss my air filter when I travel! I accidentally bought the (purple?) pet version previously and that one is great as well.

No issues

I was cutting up regular filters and using them for a long time; you can use a paperclip and strong tape to trip the little mechanism that prevents this, but over time I wanted to go back to the proper HEPA filter. More expensive sure but so much less trouble than cutting through those other filters and taping everything in to place.

I liked that this one is the real product that actually fit into my air purifier. The price fluctuates every so often. It works as it is supposed to.

We have cats and kids that go in and out all the time, and we are always coming and going ourselves. lots of dust and dander. So, we have 3 air purifiers running constantly. I ONLY use these filters in my purifiers. They are the BEST! and keep the dust and odors to a minimum :)

Fits perfect

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.
