They work great. Cuts way down on dust in our house.

I have 3 air purifiers; 2 of which fit this filter. Works wonderfully!

I bought one of these a couple of years ago. It works! I have now added another one. Its giving me just as much help as its big sister. Same model.

This filter helps the unit run as designed

Original part works great.

I’ve been using these filters for about two years now. They work very well (see pictures). They capture room dust, loose carpet pile, small particulates, etc. So much material it becomes caked onto the filter over time. Ever since I began using, I’ve noticed that I don’t have as many breathing issues or asthma attacks. I keep my filter unit in my study room as this is an ideal location. I have it running continuously even when I’m not in the room. I would advise anyone that has breathing problems to use a unit that can accommodate these filters.

So please this filter is so easy to replace!

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

So super easy to change filter. Love it. Will buy again

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.
