A. S,
Not sure about HEPA cleaners, but I am sure about the Rainbow cleaner. About 2-3 years ago we had an in home demo. I wasn't interested in paying what it costs, until I saw the demo, and realized this would be the cleaner of a lifetime, and it would be well worth it. Well, I was right. I'm extremely satisfied with the Rainbow System and would recommend it if you can handle the cost.
