UV Light Sanitizer, 55w 254nm UVC Lamp for Room Surface Disinfection up to 750 sqft, Home/School/Hotel/Travel, Kills Bacteria/Molds/Dust Mites, 1Y Warranty (Blue with Ozone)

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!

Really happy with this. Had it for a half of year or so. No malfunctions. Works as advertised. Best in small rooms. I run 2x times in larger rooms. I think it does a great job in eliminating odors and musty smells. Treatments last for a long time, months before I need to use again.

I purchased this because primarily because we have a bathroom that just does not seem to vent well regardless of what we do. We literally tore the bathroom down to the studs and remodeled it from the concrete and studs up using greenboard for the entire bathroom less the shower that was upgraded to tile backer board - with multiple coats of sealant. It has an exhaust fan that far exceeds what is required for a room of that size and as odd as this is the room used to have an attic access with a ladder so we removed that as well. Everything was prepped and sanitized while it when it was open, there are no leaks and every stud that was not pressure treated was removed. We even replaced the plumbing just in case. In less than a year the musty smell had returned SO time to sterilize on a regular basis. I put this unit in the shower (which is 7' long so it's not a small area) for the first run and then vented for 6 hours. Windows open, fan running. Still smelled the ozone and I don't mean a little...I mean A LOT. I then sanitized the rest of the room by placing the unit on a counter...same end result. The remote was key because it allowed me to trigger the unit from outside the room - love that feature. I also love that there are no dead zones because of the four bulb configuration and I love that it has a plastic protective case so it can't be accidentally knocked over. That would be an expensive lesson. It has done a solid job of killing whatever was in there because a day and a half later there isn't even a hint of musty smell. The problem is there's a lingering ozone stench which despite opening windows, turning on fans, diluting the air with the house fan, etc...it just wont go away. I highly recommend the UV only version but unless you are sanitizing something commercial or something that vents like a garage I would stay away from the ozone model. I used a mask to run into the room to turn the fan on and open the window and to check it several times and I'm still having some respiratory issues - thank you albuterol. I am not a doctor or a scientist but Google helps...the symptoms are all from high doses of ozone...so...I am returning the ozone model and have re-purchased the UV only version. Again, this is my personal experience but I think the ozone model is just too much for our house but the UV only is one of the best I've seen.

Living in a basement apartment, the smell of mold in every room needed to be addressed. Bought the one with the ozone to float into all the nooks and crannies; also took the sheets off the bed to expose the mattress that my cat had done a number or two. Blew the ozone odor out with fans when I returned and the place, including the mattress, did smell "clean". Used it again one month later and rushed out and forgot to remove one plant...not doing well. Remember to remove your plants when using.

Sadly the light melted and it took out my 100 watt 220v converter with it.

I did my entire house in about two days time. You have to have the UV light device behind a close door if you’re going to do one room at a time. If you’re going to do a larger area like living room or family room, then everyone, including pets, birds, etc., have to be removed from the house for however long you’re using the UV light. The light leaves behind a little ozone smell, but it quickly dissipates after just a few minutes. I purchased the ozone free option UV sanitizer but it still left behind an ozone odor, but it just means it was doing its job. Like I said the ozone free DID leave an ozone scent behind, but it was gone in just a few minutes.

Would give this 4-5 stars but the remote doesn’t work. I do like the lamp itself though.
