It is very close to a month now since I bought this product and so far I am happy with it. It seems so far to be a good product. Knock on wood.

Set it up it takes care of mold, viruses, bacteria, everything.

I purchased this air filter on recommendation from my Doctor. It is great….. clean fresh air!

System clicks as if you are changing the speeds and sometimes doesn't even turn off.

I bought this yesterday and received it today. I have tried and tried for almost an hour to log in and connect to my device on my android phone and it keeps saying my email is not registered. When I went to register it did not let me register. I was able to register on my computer but I am unable to connect to the air purifier with the app.

I bought the 280i a few weeks ago because some cooking smells were lingering in my bedroom from bad ventilation. I've been so happy with it that I ordered another for the living room. The app is easy to use and the unit is so easy to connect to wifi. It took me 5 minutes from box opening to get all set up. I love looking at the air quality stats. The air smells so fresh and clean. I also love how it's whisper quiet on the lowest setting, and there is a door over the panel so the lights on the display don't bother you at night.

Low speed is quiet, helps myself and clients feel safer as a massage therapist.
