Oh, I heard about this! It looks exciting. This is the device that you put over the bed while you sleep right? I have pretty bad asthma and so does my son. We've been trying different methods of preventing asthma symptoms in the home. One thing we've done is to bring in an indoor air quality management firm. I read that since the air flow isn't as good in the winter that allergens and things can build up in the home. We found a company online called Decon Pro Green. They came in a did a great job of clearing the air. It's made a great difference in our life condition.
