Does the Job!
We've had our air purifier for 6 months and it's been working very efficiently. Just a quick vacuuming once a month to keep the filter fresh is all that's needed until our replacement filter arrives every 6 months. Love how quiet it is and we have much less dust in the air.

Windmill HEPA filter
The unit is one of the best looking I have found. Rather than looking industrial, it blends in as an elegant piece of furniture. The unit is quiet and does a reasonably good job of cleaning the air. Wish it would get a little more dust and that resetting the built-in timer for changing the filter was easier. The replacement filter service is great and easy. I highly recommend this unit and filter.
