I was wondering if anyone has used the Ionic Breeze, Living Air, or Lightning Air purifiers. Or any air purifier for that matter. My house has a lot of animal dandruff, pollen, etc. My parents decided to buy a Lightning Air. It is the same thing as the Living Air (for those who know what I'm talking about). Here is a description of the Living Air I noticed the air in their bedroom (where the unit is) is much "lighter" and feels thinner when I breathe, making it easier to breathe. My nose also was stuffy, but when I went in their room, it wasn't. Anyone else have some input?
