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?!

I bought two of these air purifiers for a couple of reasons, but mainly to drown out the sounds of the garbage bins being emptied in the middle of the night, twice a week. The purifiers are not loud, but loud enough to muffle all that racket that wakes up everybody in the house. My husband and I both have allergies, and he has asthma, and we took in three dogs needing a home, so we need all the purifying of air we can get! I would show you a picture of all the junk these filters collect in a single week, but you get the idea. They are fantastic, and they last. I pop the back off and go over them every week or two with a vac brush.

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

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 product was easy to install in my air purifier. It definitely works to clean the air...just wish it wasnt so expensive!

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!

We have several Dogs and allergies. Item is easy to install and actually auto delivery makes it easy to know when to change out.

This is a great product
