GermGuardian Wi-Fi Bluetooth Smart Voice Control Air Purifier, UV Light Sanitizer Eliminates Germs, Mold, Odors, True HEPA Filters Allergies, Pollen, Smoke, Dust, Pet Dander, 28 inch, CDAP5500BCA

Amazing Purifier by GermGuardian its very sleek and and blends in seamlessly in any room, not only does this product look good it performs just as-well, i was a little skeptical at first but trying it out for the first night really opened my eyes and noticed how much it helped me with my allergies and my asthma. Thanks to GermGuardian for such a outstanding product its very quiet, the app is easy to link to the device and it also gives me a piece of mind knowing my newborn son will be protected giving me a piece of mind, this device has a True HEPA filter that is constantly trapping all the allergens and dust while the uv bulb helps defend against bacteria, a great product and I highly recommend especially for a nursery.

I've had this for over 2 years and love it! The filters are easy to install. It works so well on Auto. I love having it on the highest setting because it doubles as a white noise maker (to me) and a fan.

We have had several of the previous version of this product. As air purifiers, they work well. The remove smells from the air effectively. My wife and several friends are very sensitive to allergens and mold and these work very well (for the price) to clean the air. I didn't have issues like other reviewers connecting them to the wifi and to the app. However, do not trust the particle counter. The attached picture is of two identical models bought about a week apart in the same room separated by about a foot. The left one says the PM is over 600 while the right one says it is 3. It always says it is 3. Well, that's not entire true, occasionally it does go up to 7 or 15. But the left one sometimes stays at 3 if you keep the fan setting at 1, but once you bump up the fan speed, it shoots up, ranging from 150 to over 600. So... good purifier, but I almost with they didn't add the PM sensor because it would be better to not be told anything about the air than to get paranoid every time you look at it that there's something wrong with your air.

Works great! Have a Dyson HP04 in the same room and a coral fish tank. The ppm count seems to over estimate by a tad. Like we are talking 3ppm differential. Could just be airflow too. Mostly accurate. Usually have mild allergies, now zero. Have other models throughout the house they work well. Just would note at the highest(level 5) can get a tad loud. On “auto” you barely notice any noise, the lower levels especially. Sweet spot seems to be level 3 for my allergies and noise. Haven’t ran into the WiFi issues. Would be cool if they expanded the app to more functionality. Can’t speak to the Alexa “issues” then again I have a newer router with decent WiFi and appropriate boosters, I digress. Works great on smells. Can’t even tell I have a coral fish tank minus the sweet views. Huge fan of this company and the product. Quality buy. Also note Bigger/lesser models work as advertised as I have them throughout the house. I never write these but I felt the urge due to how awesome this product works. Cheers!

I used to wake up with slight allergy symptoms (I have dust mites allergy and carpet at the moment). Since I got this air purifier I wake up with no allergy symptoms. Didn't actually measure how well it cleans but lack of allergy symptoms seems to be fairly good indicator of what it does. I just keep it on auto, most of the time that means it running on lowest setting which is totally quiet.In the beginning the connection failed few times but seems that since then it's working fairly well so I can control it via app, however since it's just running on auto I don't use that functionality very often (almost never).The only feature that's missing is ability to set schedule (e.g. run at setting 3 between 5pm - 6pm, auto otherwise). I don't really need it but I can see that might be useful for some people. It has sleep feature but that's not the same (you cannot program sleep up front and at the end of sleep it just turns off).

One of the main contributing factors in my deciding to purchase this unit was the app functionality but I was informed that the app is no longer supported for this unit and the app will not be availbe for download anymore so if I lose the app or it malfunctions I'll not be able to use any online capabalities and will have to be at the nex to it to turn it on or off which defeat the purpoae of why I purchased it in the first place this feels like something that should have been disclosed especially since this unit costs more due to the wifi functionality very bad customer service for this and it is to late to return it

Had this for a few months now. No complaints.It is quite even on high you can barely hear it at 20 feet in a silent room. On Auto even with the office window open it maintains the air quality at 6ppm or less at low setting meaning it is completely silent unless you put your ear to it. The wireless functionality and app make it even more convenient and useful.

I read a few reviews questioning the air particle monitor but I have had this unit for six months and it has worked beautifully. Any time I cook in my apartment, the meter goes up and the unit turns up automatically on the auto setting. When the air quality got bad due to fires, the unit measured almost exactly what was reported on the government site. It is very quiet on the 1 setting (I hate noise), audible on 2, noticeable on 3, distracting on 4, irritating on 5. I had to replace the filters after six months, probably because of apartment cooking lol. Easy to swap filters. I don't use the wifi/alexa/bluetooth part so can't comment on this. Overall, a great unit and highly recommended!
