Greater than one weekBought these to replace the ones that came with the units. They helped reduce the odor great after smoke smell from a near by wild fire. I’d buy again for sure.

> 3 dayWhile 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

> 3 dayI 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.

> 3 daySmall 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!

> 3 dayThe charcoal fabric filter could be more sturdy, after a few washes it loses its shape & integrity.

> 3 dayI found the genuine filter at this time to only be $1 more expensive than the off brands. Decided to go with a genuine. Came quickly an came with the charcoal pre-filter, which I had a hard time figuring out if it did on some listings. It did fit a little more snug than the original one that came with the air purifier. This is my first replacement so Im not sure if thats common or just a mishap. Either way it still works fine and I plan to keep vacuuming the pre-filter every 2 weeks.

> 3 dayThis fit my GermGuardian model AC4100 like a glove. Easy to install - simply pop off the back over, remove the old filter, pay attention to the arrows and put the cover back on. Authentic filter replacement; will purchase again.

Greater than one weekThis 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.
