Negative Positive
Title: Extremely noisy, lots of work to clean, possibly dangerous!
Review: I've had 2 of these for a few years. I've tried to make the best of them since they were so expensive. I've also bought new blades periodically.After a few months, the unit will make an extremely loud noise even after cleaning the blades. Buying new blades doesn't help. The screeching sounds is sometimes intermittent and sometimes constant. The only option is to use it in a room that you aren't in.I've tried vacuuming and cleaning the actual tower on the inside and blowing air inside it. It seems to help sometimes. I think that particles must get trapped inside, never release and cause the screeching.I didn't know this at the time, but have since learned about the dangerous ozone emittence of the product. And am now thinking that could be the cause of some of my health problems that I didn't have before?I'm not only disappointed with this product, I think it should be recalled and customers should be given refunds.
