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.

This GENUINE Replacement filter for GermGuardian Air Purifier Models

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.

Good price and got them fast.

This is easy to install and works well.

A little pricey since it has to be changed every 8 months or so... I hope buying the original pays off for the air quality but since we cannot measure, how to be sure?

It is a good replacement and works as expected

So easy to install. What a difference have purified air is.

Filter fit and working properly. Thanks.
