    Keeps Dust off everything!

    We bought this a few weeks ago. Very easy to start up. We are amazed at how much less dust settles on furniture!

    Lost package replaced!

    They sent me a replacement filter. Loving the purifier so far which was recently purchased. Will continue to purchase purifiers for other rooms as construction wraps up.
