Works Well
We were surprised to find a plumbing leak under the upstairs floor of our 1960s house. We were even more surprised, after taking down the ceiling that there was black mold and fungus growing. I am HIGHLY allergic to mold. After doing our research and learning by trying that alcohol doesn’t actually really work to kill it, we found H2O2 does because of the oxygen it breaks down to, but that Vinegar works the best as it gets down to and kills the bottom of the roots of the mold, we began using that.Having started with the alcohol (do extra research online before trying something, as answers are not always a 100% good answer as we learned), and having a situation where the location required applying via spraying/liquid, the mold that wasn’t killed by the alcohol became airborne and traveled up the stairs. So from that point forward we were in a war of covering surfaces in the stairwell and respraying in the “ceiling” with vinegar. Each application got better and better. We were fortunate that the temperature outside was stuck on cold with no precipitation of any kind so humidity in the house stayed low enough to entertain the mold’s growth; additionally we were able to open windows ever so slightly for air exchange and use space heaters in order to avoid moving any mold away from the small area it was in.That’s when we got this product. It did well except that as we know and you’ll want to know too, ozone is dangerous to breath in and can break down some materials into toxic, flying particles. The area we needed to treat was free of unwanted materials, but when turning the device on we would have to set it up, turn it on and head out for a walk, a drive…somewhere outside of the house. We only used the machine in 30 minute increments to avoid an over abundance of ozone.With persistence alternating with the Vinegar on surface areas and the light/ozone machine we have conquered it.An added addition – This company also has a similar device with the uvc only, but without the ozone. After all our research I believe that the uvc only might have worked as well without needing to leave the house as uvc also kills mold on its own. We bought a different product from AZ that is a plugin that runs continuously, protects your eyes (uvc light is dangerous for eyes) and has a smaller footprint I’ve tested it in a bedroom that has toxic fragrance in it from prior guests that use scented clothing products – these scents don’t dissipate for a long time. The plugin with only uvc worked fabulously! The scents that had stayed stubbornly from 6+ months were gone in 24 hours!

Amazing product, only a tiny cosmetic flaw.
I am very impressed with this light. I was initially only looking for a uv light to help clean my bathroom and prevent mold. But I was curious about the ozone aspect of it too and thought I would try it out because I also had an annoying cat pee smell that was hard to remove from my bedroom of a house I recently moved into.Not only does the uv light work great like I primarily purchased this for, but the ozone model also completely removed the gross cat smell from the bedroom which I am so happy about and did not expect it to be completely removed.Also I love the design and the price is really good for what it is.The only issue I’ve had is that the light on the 90 minute button stopped working. So it still works to set it for 90 minutes, it’s just that that button doesn’t light up like the others when selected. A small enough problem that I don’t feel like it’s worth it to get a replacement or reduce my rating or anything, but just a small annoyance.
