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

The Guardian Technologies GermGuardian Air Purifier Filter fit perfectly in my kids air purifier. The old filter was practically black and was in dire need of replacement. This filter fit perfectly in his purifier, started filtering out irritants in the air, and he stopped sneezing and was able to sleep well once it was replaced. If you have a small Germ Guardian Air Purifier, these filters fit perfectly in and will help get your allergies in check.

Easy to install, not terribly expensive and does what it is supposed to do. The amount of dust it catches is amazing.

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

Work well

These filters last for less time than they say they are supposed to. And, the charcoal filters are not as effective as some of the other brands available. However, they do work well for about a month & 1/2. Nowhere near the 6months as stated on their product information! Ive found that it does a much better job when I use their HEPA filter with another brand of charcoal filter. If you are thinking of buying an air filter from Germguardian, Id suggest that you buy one to two sizes larger than they recommend for small rooms.

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

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.

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!

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!

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.
