  • Love it.

    I bought this to add to other air purifiers I have in my home. This one I put in the kitchen - breakfast room area. It works great. I feel that it removes particles in the air & I seem to be able to tell that it is doing some good. It is a little bigger than I expected.

  • Works well

    Helps with allergies, though larger than I really wanted, and the power and fan speed lights are brighter than I would prefer for the bedroom.
