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

We got this during the recent Purpleair smoke event from the Canadian Wildfires, which came down & blanketed my city. I went outside the first day not knowing anything was going on & it smelled like a building was on fire We have this small Germ Guardian air purifier, is germ guardian one word? Probably anyway weve had it on/off for the last year or more. Needling to change filters due to the poor air quality & the fact the old filter was likely useless, we got this. Its not like this is a $500 air purifier to begin with so i wasnt expecting a new filter to change that but it works well enough for what it is.

Lucky that we have it.. The air quality is bad recently due to vacavile fire

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!

Ive been buying these for a few years now and they just changed how the black filter is made. Im not a fan of the new material at face value. It looks like a way cheaper quality material and one that Ive never seen before in any HEPA filter. Im now happy about the change so far. Im still undecided if the change has degraded the quality of the filter in general. It also makes me question whether the white filter design was also cheapened. I was pretty happy with the Gem Guardian until now. UPDATE: Ive had this new filter in for about a week now and I was shocked how much dust was already on the black filter already. Im thinking this new style filter actually filters out more than the old one does so Im increasing my rating to 4 stars now. I also washed the black part and it didnt fall apart as expected and was surprisingly easier to clean than the older one. The old design would have dust getting stuck inside the holes of the filter and Id have to wash it for a while before i could get everythign out of it. The new one seemed to clean up much easier because the holes in the filter arent as big. It cleaned up well and didnt degrade like I expected. Overall Im actually liking the new design better now.

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.

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

This filter is the same as the one the unit came with. It is very easy to install and is working great.

This is a HEPA-rated air filter for a unit I use in my bedroom at night to help me sleep. After about 6 months use I needed to replace my worn filter for a new one. This one fit the bill. I suppose it cleans and filters the air, the filter sure looks like its battle-worn. So pop in the new one and I suppose its doing its job and cleaning the air I breath. Dont know if it works against Covid or not but taking no chances. My inside air is going to be fresh and clean with two different air filters running, both HEPA, as well as my home a/c unit with HEPA filter.

It works as expected. My last filter I changed at 90 days just because of COVID-19 pandemic. It wasnt gunky dirty but there was visible dirt just from running it a few hours a day. I wanted to change it to get rid of any virus germs that could have been lingering there.

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