Bought the 400S Smart True HEPA Air purifier to be able to control it from my phone. It is quiet. I like the feedback with the PM2.5 comparing indoors to outdoors. I also like the ability to program according to the day of the week or daily.
Love this Core 400S smart air filter. Already had the core 300 for bedroom and got this for living/dining area. Makes the air clean, no bad smells emitted, ozone free, easy to operate. Gives peace of mind knowing it’s a true HEPA filter. Great company, very well rated.
Absolutely perfect! When it’s not on you can see dust in the air.. but when it is on all the dust is removed and the air is cleaned!! We have 3 large dogs and it helps soo much! I will be getting a few more to go around the house!
Very quiet on auto setting. Touch screen is very easy to understand. Biggest challenge is being able to contact support when you have a question or an issue. No way to talk with a person. Email can take a few days to get an answer, If support was easier would be 5 stars.
