Germ Guardian FLT4825 HEPA GENUINE Air Purifier Replacement Filter B for GermGuardian AC4300BPTCA, AC4900CA, AC4825, AC4825DLX, AC4850PT, CDAP4500BCA, CDAP4500WCA and More, 1-Pack, Gray

I have used these for six years and I have no complaints

We have COPD, asthma and wildfires to deal with here, without our air purifiers our quality of life would suffer greatly! I highly recommend, even if you DONT have respiratory issues!!

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 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

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.

I suffer from bad indoor allergies. Dust and cat fur, to be specific. This filter has helped in keeping my allergies at bay in my bedroom. Plus, you can see all the dust thats accumulated when you change out the filter. Its incredible. Its a good filter, and this replacement fits well.

This is the only filter for my Germ Guardian HEPA GENUINE Air Purifier. My local Target store never can keep a steady stock. Therefore, I thought of Amazon for my needs. The prize is perfect and better than what Target offer. Thank you Amazon for having this filter in stock. My allergy says, thank you.

I bought one of these a couple of years ago. It works! I have now added another one. Its giving me just as much help as its big sister. Same model.

Good price and got them fast.

Filters air very good. I have a lot less dust in my bedroom.
