Hi @cloe001, I had not heard about it. It does sound interesting from the review I found and it's cheaper so that's a couple of things going for it for me. Not being able to clean the inside of the hose is a big no for me...I hate washing the hose and it was one of the reasons for me to purchase the SoClean 2. One of the comments in the review - The Lumin has not been approved by the FDA to sanitize the hose. This is because not every hose is the same so it is still better to clean your hose by hand. I'm sure it would be a good choice and I might re-evaluate. A downside for the SoClean 2 is changing the filter every 6 months at $36 a pop.

I’ve been looking at it too & after researching all of them I think this will be the best choice. I’m on the fence because so many people say why waste your money...just clean it yourself. Talk me into buying it. I want it & need a nudge. Thanks for taking time to read this!!

Ozone breaks down very rapidly in an open environment. The ozone produced by the SoClean machine is contained in the system and there is a filter (replaced every 6 months) that helps ensure full breakdown. Even if there was leakage, the concentration of ozone produced by the machine is of dubious risk (unless perhaps you were pumping it directly into your respiratory system). That said, I never open the lid of my SoClean machine when it's running (generating ozone) or during the 2 hour period when the yellow light is on...just to be on the safe side!
