love this worked perfectly

I have a multiple cat household--to say the least. Although I have done all those expected things to reduce the odor of litter pans and pets, the air sometimes just needs to be refreshed. Ive accumulated three Germ Guardian air purifiers over time. One or all of them are always on. Two are on timers, the big one near the litter pans runs on lowest setting 24/7. The one in the bedroom is on a timer because I forget to turn it on when I go to bed. Im certain a percentage of it is the white noise, but physically, my eyes often feel sticky to actually a little crusty, and during spring and summer, my throat can be itchy when I wake up. Also, when I switched to an alleged low-dust plant-based litter, the dust was absolutely unbearable. A fine layer of powder settled everywhere in my house. I was miserable and ready to go back to a clay litter. The two filters in the main part of the house go a long way in reducing the dust in the air and on my furniture and floors, the reason why one runs 24/7 near the pans. However, in the years since I bought my first purifier, I have seen the charcoal layer of the filters get thinner--dont know if it changes the performance of the filter. I dont believe the white folded portion of the filters have changed much, but the charcoal layer has thinned considerably. I know this because I found an older filter that fell behind some cabinets in my garage and only recently pulled it out to use it and noticed how much thicker the charcoal layer is. Overall, I still recommend the filters and the purifiers for the longevity and effectiveness. I have all of the sizes on a six month subscription so when the new one comes in I just change them.

To filter out the dog smell during winter I purchased an air filter which this product fits perfectly! This filter I am replacing every 4-6 months. Easy as pie!

I like that the filter is replaceable. As a chief building engineer these filters far out perform washable filters. My experiences have been that these filters collected far more dirt bacteria and odors the best

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.

Original part works great.

Pricey but will purchase again.

Filter didn’t last as long as they said it would.

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