Good item.
It arrived two days ago. I haven't disconnected it since then. And so far it has been working perfectly. The humidity smells have disappeared at home and it is perfect for the kitchen too, as I don't have a fume extractor it makes food smells go away quickly. I am loving it so far.

slick and quiet
slick design..this came to my door in two days...and today it is running full speed and I can already tell the difference in the air quality, they have been working on the underground gas lines for over a month now outside my home and there is a lot of dust this should do the trick, I liked the reviews so I purchased it. I love the flow of it, and the beautiful sound it makes..white noise and not loud at all and I have it set on high. easy peasy purchase.

Improved allergies. Easy to move around! Love it!
Took in 3 cats born by our shed to rehome. Fell in love and got a room purifier for the bedroom. It helped our allergies so much we got this one. I love it even more! It"s on wheels so easy to move around. The filters collect so much ick. Asked my close friends if there is any kitty smells and they all saw no. Our allergies are much better too. Great find! I turn it off occasionally thinking I will remember to switch it back on in a bit %26 forget. After a day with it off both our allergies are back. Then I remember to turn it back on. Glad we have it.
