I purchased the GermGuardian and replacement filters bc my daughter bought it for her house. I have not replaced the filters as of this date. However, the filter appears to be easy to install.

Though they’re a bit pricey. Sigh. But they do the job and no one else will, my dog has zero interest in air filtration. He’s about the kong bone. Can’t say I blame him. Also these are easy to install and you can slip the old used filter in the box for easy cleanup as well. This is a concern cause you don’t want to drop a very used filter onto carpet, which I have in some rooms. That would be a very unfortunate outcome. That’s why it’s great to have a form fitting box to quickly toss the old filter in. One and done. That’s what I say.

Fit perfectly!

I love these filters. Solidly made, has some free installation, comes as 1 piece and does a great job. Also, these are longer lasting. Pricey but the quality is un-matched. Highly recommended

Like it. works very good.

Fit the germ guardian i have fine . Was the right one and had no problems . Work fine with my machine.

Works well to eliminate odor

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.

I’ve been using these filters for about two years now. They work very well (see pictures). They capture room dust, loose carpet pile, small particulates, etc. So much material it becomes caked onto the filter over time. Ever since I began using, I’ve noticed that I don’t have as many breathing issues or asthma attacks. I keep my filter unit in my study room as this is an ideal location. I have it running continuously even when I’m not in the room. I would advise anyone that has breathing problems to use a unit that can accommodate these filters.

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.
