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

Great product. Used to replace filters on the air cleaner I bought that doesnt make there filters any more...) :

this is an air cleaner filter. it seems to work fine.

These are great. I have pets an allergic to them an these are great. I have 2 sizes of these air purifiers an they are the best. The filter I like. Bought off brand these are best!!!

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.

Used to be much better quality- the top and bottom of the filter used to have some foam padding for a snug tight fit. Now the fit doesnt seem air tight. Also the pre-filter is shedding black debris everywhere. Its so thin and poorly made. When you put your hand on it youre fingers are covered with black debris? Was it always like this?

I went to the allergist and so I was allergic to every tree grass dust mite so I got this to help with breathing works very well

It works fine super easy to install and I can tell the difference in the air with this new filter.

I was a little skeptical about how much this would purify the air. Then i replaced the filter & WOW! what it filtered out was amazing! The picture makes it look like a brick pattern is on the filter, but no— the white is actually all the garbage that it filtered from the air! I definitely felt that my allergies were improved this spring/summer, but thought that maybe wearing a face mask at work helped too. In any case, it does the job, easy to replace filter. Literally about 10 seconds.

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 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.
