Great Filters!
These are quality filters that work well to keep our air quality environment healthier. They are easy to remove and replace. Our home has older carpeting and I think we'll change our filters out every four months. We really notice a difference in the freshness of the air using these well made filters!

Best one yet
Hands down the best deodorizing air filter I have owned. We have a German shepherd and 2 cats so it draws in and traps stray hairs we don't catch with the vacuum. Quiet and long lasting.

Replacement Filter — Easy to Install and Works Great!
We bought the GermGuardian Genuine HEPA PURE Replacement Filter B for our air purifier, and it has been excellent. It fits perfectly in our AC4825 model and was very easy to install — just a quick swap and it was ready to go.The air quality noticeably improved right after we replaced the old filter. It captures dust, allergens, and odors really well, just like the original filter. Plus, knowing it’s a genuine replacement gives us peace of mind about the performance and durability.Overall, a great product that keeps our purifier working like new. Highly recommend sticking with the genuine filters for the best results!

Great product!
I use this in my 35ft travel trailer( home on wheels). It does a great job! You don’t realize how much yuck is in the environment until you change the filters. That would be the only draw back is filter replacement costs. I have tried products with a washable filter but this does a better job with its heavy duty filter.

Excellent replacement and watch for price drops
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. I've 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 don't fooled by the permanent filters, it's one of the reasons I got away from the Air Genius, the filter wouldn't clean properly. So, I knew the Germ Guardian had to have replacement filters but I hadn't bought any. I bought one of the generic versions here from Amazon and it's good but when I turn my purifier on, I love the fresh smell, it's 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 he's a little guy and he stinks. He can't help it. I give him baths but I think it's because he's so short, his belly hits the ground. I'm picking on the puppy. He has hair that sheds and sucks up any moisture so he don't 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. It's like flipping a light switch on. The room it's in is roughly 15 x 17 and it also keeps the air fresh in the 8 x 10 bathroom that's connected to the office. Not the funnest present to buy yourself but if you're like me, your nose and sinuses and stinky puppy will thank you!
