GermGuardian Genuine Carbon Air Purifier Replacement Filter for Air Purifier Models, AC4825, AC4900, AC4300, CDAP4500 and PureGuardian Model AP2200CA, 4-Pack, FLT22CB4

Works great!

My dogs and myself have a problem with dust and pollens and this is the machine that works. Pua, Husky dog often sleeps right next to the machine to stop her heavy breathing. Living in Hawaii we often get some heavy pollens along with our beautiful flowers and trees.

They work, they fit, they’re exactly what you expect

My first time to get a replacement for my germguardian air purifier. Shipping was fast and it is just same as the original in the air purifier.

It's a good product at a good price

Ordered these to keep on hand for when I need one

Every time I change this little black strip filter it takes a few seconds and the results speak for themselves. I see quite a bit of dust and hair on the filter, which turns the filter almost white/light grey. I have two of these filters running almost 24 hours a day, and at night they go on high to sleep. You still need to dust some, but the quality of air is reasonably better. You can see when you remove the filter how much dust you didn't have clean from your home.This filter goes on top of the HEPA filter on the outside. This is the second layer filter that increases the longevity of the main filter. Competitive pricing, and a useful product. They have stuck on just fine so far.This works decently enough for allergies, pets, and dusty areas/states. I swap these out when they turn light with dust, and (I change the main* white colored HEPA filter when it looks darker than what I prefer.) Simple logic.

Really catches hair and dust. Prolongs life of purifier filter. Highly recommend!
