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

I had my filter replaced about a year ago. Longer than the recommended. But the charcoal filter this time is a lot harder than what it was previously. Im not sure why but its noted that the charcoal filter was also a bit creased towards the top of the filter. The box was not damaged in anyways so it wouldnt be due to shipping. Maybe its due to packaging. Anyhow, the filter functions fine and theres no smell either which is great. The HEPA filter is the same as what it was previously.

Perfect for ease and does the job

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!

Perfect fit just as advertised

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.

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.

While these are just filters, the machine from this manufacturer is also very good. I have issues with allergies, bronchitis and asthma but these systems, including the filters offer relief. Recent years added significant wildfire smoke in this region, but I got through that as well. Like this brand

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.

This filter definitely works. From dust, dander, smoke, particles in the air etc. There is no match for this unit. I would recommend a different unit if you are using this for your sleep schedule; near your bed. This is not the most quiet machine ever but it is not super loud. Right in the middle. I would consider this unit to be a Post Malone of the air scrubber world.

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
