I have a Dyson hand held vacuum which helps a lot as I'm asthmatic and the cleaner is light-weight and efficient. I recently ordered the hot and cool purifier. It's performance is impressive. The air is clearer and it can be set to blow straight ahead or in a wide angle. I ordered it on Saturday and it was delivered on Sunday morning (you can choose a morning or afternoon delivery slot). I'm keeping it on Auto and it does it's stuff automatically increasing or decreasing the flow as necessary to keep the air clear. It picked up the accidental blue smoke in the kitchen almost immediately and immediately switched to the highest setting to clean the air. Perfect. Can't wait to buy one for upstairs.
