Pretty easy to set-up. Very quiet. Seems to come on in the morning and evening as the thermostat changes.

I bought 2 of these- we noticed a clear quality of air within minutes! Love this product and would highly recommend!

This unit provides wide area coverage and easy to clean. Already had one i have been using a couple years.

Nice, well built, substantial piece of equipment. Silent until the higher settings. Remote did not work but maybe just the batteries.

We love this air purifier. It does everything it said it would do. It not only filters the air from dust and allergens, it also kills viruses and bacteria.

Unit has developed an annoying squeak while it’s running and it’s just been cleaned. Sounds like it is a bearing or the fan-not sure. if it continues I may have to return or exchange

I am extremely happy with my purchase, so far. However, I had a "red" light come on that stated I should clean metal grate. I have cleaned the whole machine and cannot get the light to reset. Any assistance is appreciated!

I bought this unit to replace the 9000. We put the 9000 in the master bedroom. The new unit is working very well for the rest of the house. We have never had any problems with the older unit.

Works great. Nice added spare filter.

Very quiet and efficient. Put in my bedroom which is 500 sq. feet. Glad I made the purchase.
