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.

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!

Works but could be better fitting into filter and more sealed

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.

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.

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?

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!!!

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

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

The Air Purifier is a great machine, small in size but puts out a strong volume of air. I put the machine on the top of the shelf just below the furnace and air conditioning vent that exits near the top of the ceiling above the bedroom door. Often times we have to reduce the airflow of the purifier to the lowest as it cools the room down too much during the night. Above all all it quiet on all 3 settings and makes it very nice to have on during the night when we are sleeping.
