Clearly you know nothing about Rainbow even though you've sold both. This must be why you don't work there anymore. The Rainbow just spews out spores of mold back out into the air. Where do you think mold comes from? Wet and damp places, just like a Rainbow! All you're doing is creating a breeding ground for bacteria every time you turn it on, then all of that gets into your breathing air and all over your surfaces in your home. You need a strong filtering process, such as the FilterQueen has in order to truly get rid of airborne partials, allergens, and mold. Maybe you should research a little more before you bash a product.
