I received my Honeywell Air-purifier the other day. I plugged it right in after installing the filters. It has four different cleaning levels and I put it right on Turbo(with a dog and cat in the house I figured the highest would be best). Within an hour or so I could breath better. It seemed really nice. The air seemed cleaner,cooler.The touch screen controls are very easy to use (my dog turned it on twice). It seems to cut down on the dust flying in the air. You don’t need to change the filters very often but they seem very easy to order. Overall I’ve been having fun using it. I am very happy with it.
