Martha Rempel: I have purchased these filters many time. All of our bedrooms have GermGuardian air filter machines which use these filters. Fit perfect.

Travis: The filter fits the model I got at Walmart which was the AC4200 Germ Guardian. Funny enough, this new filter makes significantly less sound and I can (subjectively) tell the difference with air quality as my last filter was about 1.5 years old. I kept vacuuming my older filter but the felt broke, I'm glad I got this replacement.

Neo: A bit pricey but this is the best air purifier I've used through about 15 different models. The only dislike is the loud audible beeps even when using the timer with sleep mode. Quite unnecessary. Other than that i highly recommend this purifier.

MarjorieZinMP: I've had this air purifier for almost a year now, I bought it at the height of the wildfires in California in 2020. But I wanted to write this review about last night! Late at night I turned on a space heater in our bathroom and in a moment I realized it was burning up! I quickly unplugged it and took it out of the house but the smell was terrible snd persistent. I did try to ventilate the house thoroughly but the odor did find its way into our bedrooms. I turned on the air purifier and yes it did work! I was so relieved that we could sleep without breathing possibly toxic fumes. The sound it makes is comparable to that of a white noise machine and easy to sleep with. When I woke up in the morning the bedroom window was still open and I got a gust of the perfume odor from my neighbor's laundry in the room too. I hoped for the best and yes, the Germ Guardian was still running and soon the room smelled fresh again. Our bedroom is around 12 ft by 16 ft and it seems to work fine. I'm happy I chose this item!

JHW: I purchased this to use at night in my bedroom. I have dust and mold allergies and this air purifier has helped me a great deal with sinus issues while sleeping. There are various levels it can be set at. Both the 1st and 2nd levels are very quiet compared to other air purifiers I have had in the past. So if you like it quiet at night, these settings are not bothersome. At it's highest level, the sound level increases a fair amount, which for me is great for those evenings when I need some white noise to drown out the sounds from noisy neighbours or kids at night. I have been happy with my purchase.

rcg: True HEPA filter replacements are pricey, but you will notice the difference! I put this next to my cat litter boxes to keep dust and odor under control. The boxes are in my office / crafting room, and I can now spend all day in the tiny room without being sickened by the litter dust and odors. It is very quiet on all but the turbo setting. The noise is a non-jarring white noise that isn't unpleasant, but also very easy to drown out with headphones. I keep it on medium speed and turn to turbo when cleaning the litter to capture the dust. My nose and lungs are happy

Teela: Very easy to use. Great for a small room. It's not very big but perfect for what I needed. Good price for the system, however the replacement filters are pricey for being so small. This is why I did not give it all 5 stars. BECAUSE its so small, I think I will be needing to change filters more often than my old one, so the filters being expensive is not great. I read reviews about it being too noisy, and people can't hear their TVs?!? This thing is A LOT less noisy than my previous filter (older and different brand). It is only noisy if you crank it up to the highest mode; which I didn't even know it had a mode that high.... "Turbo" mode. THIS mode is noisy, but I didn't even know that setting existed! I am happy with it on setting 3. Of course it will make some noise but nothing out of the ordinary for a hepa filter; and like I said, is quieter than my previous hepa air filter. If you need an affordable filter machine for a small room, I recommend this one.

Morgan Lacefield: seems to work great used it in small (110 sq foot) bedroom on the side of the house that never gets any sunshine. we keep the door shut and the room always had a mustiness about it. Put this in place on the end table at low speed (4 speeds - sleep very silent - low white background noise like a small fan - med like a large fan - high like a vacuum cleaner maybe not quite that bad) low speed seems fine. we leave it on all the time and its just loud enough to be soothing. Musty smell gone within 24 hours and has never come back. Since this is a bedroom and closed off we choose this unit with out uv (no ozone produced) it just has the hepa and charcoal filters. Been operating about a week so I can't speak to longevity or filter life, but it's simple to use and maintain and seems to be a study, well made device.
