I'm not sure if we are allowed to endorse a product or not. I don't sell this product. For the past couple of years I have used this Ionic Pro in my bedroom and it is so much more effective and efficient than any other clean air machine I have used. I ordered mine off of tv one night. I had four of the smaller hepa filter machines spread out all over the house. Those filters cost $18.99 each, after the cost of the machines. They really need to replaced on a monthly basis. I couldn't afford to replace four of them that often. I finally just threw all of those machines away.
The Ionic Pro has a cylinder that you pull out and wash. It's really easy. A light comes on to let you know when it needs to be washed. The machine is so quiet. I have severe asthma and I would never buy another clean air machine that had an actual filter that had to be replaced. I highly recommend the Ionic Pro.
