Last year, I threw away my Honeywell Air Genius 5. As much as I liked it, it was frustrating to maintain and it had a mind of its own. I trust Peer Guardian products. Ive had numerous humidifiers made by them so I bought the Germ Guardian AC 4825 to replace the Air Genius. Out of nowhere, about 6 months after buying it, it started flashing a red light to change the filter. Air Genius had a permanent filter. But dont fooled by the permanent filters, its one of the reasons I got away from the Air Genius, the filter wouldnt clean properly. So, I knew the Germ Guardian had to have replacement filters but I hadnt bought any. I bought one of the generic versions here from Amazon and its good but when I turn my purifier on, I love the fresh smell, its probably not even noticeable to most people. The generic replacement filter never gave me the fresh air smell but it was doing a good job on everything else and at the time it was eighteen dollars less than the name brand, about a sixty percent difference in price. I need that fresh smell. I have a puppy that stays in my office and hes a little guy and he stinks. He cant help it. I give him baths but I think its because hes so short, his belly hits the ground. Im picking on the puppy. He has hair that sheds and sucks up any moisture so he dont really stink but he has his own unique smell. The name brand filters help with that and give me a more fresh smell in my office. This upgraded version is a perfect fit and it comes with an attached carbon prefilter. It goes right in, no problems and it brought the fresh air back. Simple, easy, change and I caught these on what I assume was a sale for right at twenty dollars, so I bought 2 of them. They are usually around thirty. I also recommend this purifier even over the bigger version and the other brands. I run it on the medium speed from the time I walk into the office until I leave the office. Its like flipping a light switch on. The room its in is roughly 15 x 17 and it also keeps the air fresh in the 8 x 10 bathroom thats connected to the office. Not the funnest present to buy yourself but if youre like me, your nose and sinuses and stinky puppy will thank you!

I purchased these for my home because my father was coming to visit and I also suffer from bad allergies and sinus infections. These definitely helped keep dirt and animal hair at bay. Last about 6 months before needing to be replaced.

It is a good replacement and works as expected

Like it. works very good.

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.

Great price and easy to order.

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.

Ease of use

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

Have used this in my mother in laws assisted living apt. She swears by it. Before she always felt she had allergies and it was dusty. Since we bought her this we have kept her in new filters whenever it tells us.
