Customer Service did a great job replacing a damaged filter with another filter as soon as I received it damaged.

Free shipping. Quick

Could not be more pleased.

Even though refurbished the purifier looks brand new. Works flawlessly. Very easy to set up with clear, well written instructions with diagrams. Different color lights let you know the air quality, which also helps you learn what causes bad air quality in the home and when. On the first three speeds it is barely noticeable that it is on.

Excellent
