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

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

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 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.

Works great

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.

Aug. 2019 product recd. Update on prior reviews. Been ordering these filters multiple times for a very long time. The purifiers work so very well. Noticed that the pre-filters are getting thinner and thinner. The 2 I just received are tissue paper thin and many spots thin enough to see the pleats on the main filter thru. Will keep an eye going forward to see if the filters are made thicker (as they used to be). If not, this will cause the main filters to have to be replaced even more frequently. Not something I am willing to purchase more frequently if not necessary. Works wonderful and keeps the air cleaner then expected for a smaller unit. Filter is easy to install and has to be changed with your usage of the purifier. A great system.

Perfect for ease and does the job

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 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!

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