It works great !

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.

Easy, clean, lightweight!

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.

Works well to eliminate odor

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.

It works great Wish they were cheaper

Weve been using these air filters for several years, and after recently reading through reviews to order a new batch I became a bit skeptical. Luckily, my wife bought us an air quality monitor as we struggle with horrid air quality in Denver due to the fires in California. I live in a house with only a swamp cooler and no other ventilation. Every time the swamp cooler kicks on, our indoor air quality becomes unhealthy when it pulls in all that air. So now Ive closed up the windows and am running two Guardian air filters at once to test their effectiveness, and the results speak for themselves. Our air quality is back to good with particulate matter and VOCs, as my brain fog is lifting. Another trial-by-fire was we snuck one of these into my grandmother-in-laws house and closed the door to the guest bedroom. The infamous old person smell was gone within an hour or two, and the air simply felt lighter. Its rather remarkable.

Amazing product!
