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.

Says change filter when red light flashes. Red light continues you flash even after installing new filter. Why??

So please this filter is so easy to replace!

Works well with our Germ Guard air purifier

Easy to use and match with current filter

Ease of use, installation is simple and fast. Viruses and/or bacteria dont have a chance with this filter. Pet hair, dander and other allergens are significantly reduced if not completely eradicated

Good quality, received it fast. My old filter looked the same but it was full of dirt.

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 :)

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.

I purchased the GermGuardian and replacement filters bc my daughter bought it for her house. I have not replaced the filters as of this date. However, the filter appears to be easy to install.
