This is even better than my first one that I still use. Low the ionizer and appreciate that when there are toxins in the air the light around the on/off button lights red to green according to the amount. And what I love about both are how you can turn the lights on the control panel off during sleep while it continues to work beautifully. Ready to buy one for my office.
Placed purifier in the Master BR/bath part of our house (600 sq. ft.). Removed the pre-filter after two weeks. Very impressed to see all the dirt, dust, and ?? that was removed. This model is quiet and 2nd speed but not annoying at higher speeds. Control lights can be turned off or left on to serve as a night light. Very easy to operate. Terms of guarantee are generous.
Since buying this purifier I sleep much better, It gets rid of orders and the air seems to be lot cleaner. The noise level is very low. Happy with purchase.
