love this worked perfectly

I bought this unit and an extra filter December 8, 2021. It works fantastic! I love how easy it is to change the filter. Its nice looking. Its super quiet and seems to do a very good job. It even lets you know when to change the filter! However, Its January 31, 2022 and one downside is, I am a heavy smoker and the filter is just black and it stinks to high heaven! So I got a month and a half out of the filter. The other downside is the filters are a little pricy. Even though the change filter light is not on on my unit, the odor tells me its ready to be changed. I realize the 6 month filter change they advertise was probably for non-smokers. But I still love it! Worth every penny! I will always have an extra filter on hand. I clean the Hepa filters on my vacuums (they say not to) and they still work good as new as far as I can tell, so Im gonna try to clean this filter before I toss it. Who knows? I might get an extra month out of it! Funny thing though...when I checked the filter just now I thought...is it supposed to be brown/black? Apparently not! LOL But yes, I highly recommend it! Just might have to change out the filters more often if youre a smoker.

No issues

Fit perfectly!

Judging by how filthy they are when I change them, these filters are really pulling in dust and particles in from the air. And they last a long time too.

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

Works great

Nothing

Easy to use and match with current filter
