germguardian Guardian Technologies FLT41002PK FLT4100 HEPA Replacement Filter E for AC4100, AC4100CA AC4150BL, AC4150PCA, 2 pack, Black Air Purifier

These Guardian air purifier filters are the absolute best. Even though they are small and for a smaller air purifier, they do an outstanding job at cleaning the air and making it fresh and breathable, especially for people like me who have allergies and asthma. And they do this even in a house with a lot of animals. I’m so impressed by how well these air filters work. I keep coming back and getting this brand filter for my air purifier because it simply does the job right. Highly recommend.

You can reorder easily and you can wash the black filter and not have to replace the entire filter so much.

Product was as advertised. It fits great, works well in the air cleaner. The only problem was it was kind of pricey.

Purchased this E style replacement filter pack for our Germ Guardian AC4100 (the little one that looks more like a speaker). Have had the air purifier for just about a year, but officially only has about 5 months of use on it. Both filters were quite dirty, so figured it was time to replace them. As far as I can tell, this was the genuine filter set for our purifier. Visually the same as the old filters (minus all the nasty filth), and fit into the purifier exactly the same. Have had the new filters in for half a day and can notice a positive change in the smell in the room, and the purifier seems to be running just a little quieter. Old filters may have had a little restriction, or I may just be imagining things.

Bought these to replace the ones that came with the units. They helped reduce the odor great after smoke smell from a near by wild fire. I’d buy again for sure.

I love my Germ Guardian air purifier, and the filters work very well! I live on the coast where its continuously damp, so were prone to mildew and mold. We also live in an older building that hasnt had many renovations, so dust is a huge problem as well. I use the air purifier in my bedroom and it does a wonderful job of keeping the air much more clean and breathable. I also use some charcoal moisture/odor absorbers in closets and underneath the bathroom sink as extra precautions. I keep the Germ Guardian running literally around the clock, and its held up beautifully! Definitely worth the $60!

I have such bad allergies. I love that my machine is about 4 yrs old and I can still easily find new filters here on Amazon!

The whole air purifier is great. As others have stated, it seems as if they have gone cheap on the carbon filter. You can buy a bunch of carbon filters from anyone, and just double up. After that, it is still a good price

I really like my table-top filter. Judging by the discoloration that happens, I would say that the filter is taking a great deal out of the air in my apartment. Between allergens and other current health threats, I am glad to have these filters cleaning much of the stuff in my air.

Works but could be better fitting into filter and more sealed
