Customer Ratings & Reviews

Cleans the air in my bedroom, quiet, small and easy

the filter works well and is a replacement for an older product who's filter is no longer available. I am please with the quality of the product and the speed in which it arrived.

The purifier/filter worked better than I expected for the small size. Also easy to replace.

We bought the GermGuardian with this filter to fight the last week or so of the dense smoke that blew into San Francisco directly from the wine country fires. After about 10 days of the fire other models were all sold out which is a good thing: this model/filter worked very well to pull out the accumulated smoke particles and smog from our closed-up but still polluted house. We ran it at high settings for 4 days straight in successive rooms to bring the air/aroma up to normal for a house guest we would have. I don't know if this use qualifies as weeks or months of normal usage, but after about a week of this use I checked the filter. The black side has a lot of sooty accumulation I can wash off; the opposite HEPA side seems only slightly coated.

Great single room air filter. These replacements are long-lasting and work great. Traps everything and the carbon deodorizes.

Great price on top quality, name brand filter, and very convenient

Great air filter-second purchase - traps the dust and very easy to replace

Good filters, work good and last, good air purifier too

Easy to install and lasts long. I wish this product was always available on the web site.

Perfect for my Germ Guardian small air filter! Shipping was quick and the filters arrived in perfect condition! Always happy when ordering with Best Buy!

Great filter, great price. It definately would have lasted longer than 6 mo. I like that, better safe than sorry.

The filter is great lasts a long time. Been reordering now for a year.

Quick ship, correct replacement for the air purifier I run in the bathroom. (I smoke in there, and the exhaust fan is inop.

What can I say this filter works great I get 3 uses and wash it out after 1st use

Filter fits well and works as expected. Prefer to buy from manufacture instead of knock offs.

Highly recommended Love Love Love ......................... This is the best ............

Does exactly as it's supposed to. Filters the dust and bacteria from the air in my room.

I love my germ guardian so it was nice to see the filters go on sale. you dont have to replace them so often.

Purchased these to use with my GermGuardian AC4100. These were on sale at nearly half price. Great value!

This air purifier works great to remove allergens in the air. I use it in the bedroom and replace filter every 3 months.
