Just got my first Rainbow system and I love it! They came and gave me a demonstration in late October and I was really impressed but didn’t buy one that day. I couldn’t get the thoughts of how clean it made the air smell out of my mind. And everytime I used my Kirby and smelled the dust being blown out into the room(so stinky!) I would remember him telling me that was the fecal matter of the dust mites… When he gave the demo he had the machine just sitting there with water and air freshener in it and let it filter the air. It actually pulled dust from the air into the water just sitting there! You can run the machine like that for a few hours each week and the air smells soooo good! My parents had one when I was a kid and I hated emptying the water, but as an adult I don’t mind because I know its actually getting my house CLEAN. I would recommend this product especially to those who have dust allergies. You will get immediate relief!
