🌬️ GermGuardian True HEPA Filter Air Purifier with UV Light Sanitizer – Eliminates Germs, Filters Allergens, Pollen, Smoke, Dust, Pet Dander, Mold, Odors – Quiet 22 inch 4-in-1 Silver Air Purifier for Home Review

AC4900CA I bought this on May 26th 2017 to replace another Germ Guardian which has gone after 2 years. The first time I turned it off to change the filter, it wouldn't turn on! I will never buy a GermGuardian product again. I bought 2 of these a few years ago and they worked fine until this summer, then a few months later they both blinked for me to change the filter and when I did they didn't start again. So I bought this one thinking it was only supposed to last a few years and now this one…

This filter worked with the UV lamp and the fan at 2/3 with no problems. It runs smoothly and works great. After 2 weeks of use I turned it off to check the filter and to my surprise there was a lot of dust in it. Not blackish yet, but definitely greyish. In that way it works. Regardless of whether you have sinus problems or not, if you see an inch-thick layer of dust after 2 weeks of use, you can be sure that you are breathing less dust and bacteria. 5 stars and I will always have one in my…

At first glance these devices work perfectly. I've never noticed a noticeable difference in my allergy symptoms, but there seems to be less bird dander in the kitchen and less dust in the bedroom. After 6 months, both devices start to whine loudly. This persisted even after filter replacement and cleaning. The approx. 1.5 year old old device also started to rattle as if the bearing had started to fail. These devices work 24/7, but I expected them to last a little longer. The devices come with a

I have purchased three different Germ Guardian air purifiers, each chosen by area. This one, 4900, was for my bedroom. I bought a model 5350 for my cafeteria; that's bigger. (The third was for a 350-square-foot family suite, so I won't include it here.) By comparison, the 4900 is noticeably louder than the 5350 at its lowest speed. Fan speed control is a barely-visible dial on the front of the unit, while the 5350 has an electronic button that is illuminated on the top of the unit and easy to…

As you can see in the photo, in just 3 months the filter has already removed quite a bit of dirt, dust and airborne particles. -Opening. I have it open 24/7 in my bedroom, 12'x12'. The black filter is a new filter and the other gray filter is a filter that has been used for 3 months. (Odors) [5 out of 5]: It does an excellent job of fighting odors. (Dust) [2.5 out of 5]: Maybe my expectations were too high. high or do I need higher fan settings but I was really hoping this would help with my…

I waited almost three months before posting a review to give the product a chance. I have one in my bedroom and one in my living room and they work for me when I'm home. It's a little hard to explain but I noticed that the air seems cleaner. Due to terrible allergies/sinus issues, I would often wake up in the morning with a stuffy nose and asthma-like symptoms; However, since using these air purifiers, these cases have decreased significantly. The photos I have attached are the new filter and…

So far this air cleaner has done a good job. I use it all the time in a 15' x 10' bedroom with a single window that overlooks a busy street. The dust pollution is completely unmanageable due to the road. I have thoroughly cleaned and maintained this filter 24 hours a day, 7 days a week since it arrived. The noise level is as expected. A quiet whisper, even at night when you want to sleep soundly. Medium is low-level white noise that helps hide city noise. High is a fairly loud fan. The device…
