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

I first learned of this system when our daughter moved back home during her pregnancy and the first few months of our grandsons life. We really liked how well it worked and so got one for upstairs and one for downstairs. Changing these filters is super easy, and with the subscribe and save option you never have to worry about forgetting to. Really makes a difference in our home and we are very pleased with the results.

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.

Small air filter, but does a great job of cleaning up the air you breathe. I’m a smoker in two rather small Rooms. I turn this unit on while smoking, & turn it up higher in the evening before going to bed. The air is clean in the morning. I don’t smell nicotine when I come downstairs. I love this little unit. Small, but effective!

Easily went into my air purifier, even though it had a yellow color on the band on outside my original one did not. Really thats about all you need. A filter just has to do its job once installed.

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.

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

Great product

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!!!

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

I had my air filter for about 8 months. I have been using it 24/7 more frequently because I now live with a cat and am allergic. As you can see it works very well. I noticed when it needed to be changed when I started sneezing and was congested. Once I replaced it, I slept amazing that night with no congestion in the morning! It lasts a long time and is SO easy to replace. A very reasonable price for how long it lasts. I will update when I replace this current one to give a more accurate length when using it 24/7.
