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 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.

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

I have used my germ guardian for years and these filter replacements are great! There isn’t any off gassing or weird smell like some other filters I have used in the past. It is easy to change out and I have noticed an improvement in my allergies. I actually miss my air filter when I travel! I accidentally bought the (purple?) pet version previously and that one is great as well.

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

Definitely works. I have a smoke free house so it works great.

Every time I change the filter, I am surprised at how much dust is trapped on the filter instead of being inhaled by me and my family members. My Germguardian device is fully compatible with this filter. Were subscribed and get them monthly (4 units in the house). One thing is puzzling me though. Why the bundle packs give worse price per item than ordering a single filter?!

It works great !

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.

Pricey but will purchase again.
