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

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.

Perfect for GermGuardian. The ones in the sets are way too thick!

Works great!

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.

Use. Frequently- extends life of hepatitis filter. Fresher smell

It's a good product at a good price

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

I have an allergic induced asthma and live in a high desert location. Seasonal allergies get my asthma going and I've been able to control my asthma by having the Germ Guardian air filtration unit going day and night in my house. If you have pets that release dander and bring in irritants into your home, or if you live in heavily populated areas with pollution being an issue, I can see this improving your air quality. One of these hepa filters last me about 3 months, and on seasons where there are more pollutants in the air, I go through the carbon part of the filters more often. It keeps the costs down to buy extra carbon filters separate and that way you only have to replace the cheaper carbon filter more often, and the hepa filter lasts you even longer.

I gave it 5 stars because no problems- not saying I love the item though as it is a carbon filter for my GermGuardian Air Purifier (who loves that?) but it works perfectly. The carbon filter was exactly the same as the carbon filter "b" that it replaced. For some reason, my filter gets filled very quickly in my bedroom (I have two machines- the living room goes through 1 filter during the same period where the bedroom goes through 3 filters.) I don't know why yet- getting closet doors in case that helps. When I first got the machine I had to change the full HEPA filter three times in 5 or 6 months which is pricey. However, I noticed it was mainly the carbon filter at the front that was getting clogged. So when I went to reorder HEPA filters, I saw the carbon filters and thought I would try them out. It worked. It has been helpful to change the carbon filter once a month in the bedroom- the Hepa filter life is lasting way longer. So it was a good purchase and I would recommend it for anyone who has a GermGuardian Air Purifier that needs Filter B. I am ordering more now so I have extra on hand.

Rapidez de amazon, excelente producto y precio muy competitivo

Llegó envuelto en un plástico sumamente delgado, como si fuera pirata. El precio se me hizo elevado para lo que realmente es.

Nice to be able to change the carbon more often then the hepa since it tends to catch most of the dust and increases the life of the hepa. Great product.

These filters are thicker than the one that originally came with the unit. Fits nice. Would recommend to anyone who is interested in replacement filters for their air purifier.
