Quality

This product does a fantastic job in cleaning the air quality and getting rid of the after cooking smells.

Obviously a top quality product, glad to have purchased it

It is very sensitive to changes in the air and kicks on quickly when i am cooking in the kitchen something that becomes airborn... Read More

Low setting is so quiet that i can't hear it, middle setting is pretty quiet and high setting is a little loud but it moves a lot of air.

Price

I got it on sale when it was about $400 to the door, and i loved it so much that i bought one for my parents!

This is the real deal, true hepa with carbon.

Years ago, i had a sub $100 unit and it was pretty useless.

It is one of those self care things you would never really buy for yourself due to the cost, but once you have it you will never go back.

Shipping

First shipment was damaged, so it was returned.

Competitiveness

I’ve only used winix brand air cleaners but decided to try this highly recommended model for my larger kitchen and living room combination.
