I received my PureZone HEPA Air Purifier last week. I placed it in my bedroom and have it on level 2. I absolutely love this product. I have major allergies and overnight the congestion always builds up. However, using the air purifier I wake with little congestion and feeling refreshed. My partner says I am not snoring nearly as much or as loud. 

The product itself was easy to set up. And has multiple easy to use functions at the touch of a button. 

What makes it even better is the prefilter screen can be removed and cleaned requiring the HEPA filter to have to be changed less frequently. Great product!!
