My house has always had an odd smell since I bought it 12 years ago. My sister could smell it on my clothes even when I went over to her house. Perhaps a bit of mildew as I've noticed dusting on wooden surfaces, windows, doors, and cabinets. I've cleaned them, and even put a fresh layer of polyurethane over all my wood surfaces. I don't see dusting anymore, but the smell persisted.With the pandemic, lots of talk about treating air with UVC. That triggered memories that UVC lights are commonly used to disinfect operating rooms at work. So I gave it a go with some lights I picked up from Amazon. Well, success! But hard one as I had to do each room like 6 times, moving the light each time.From reading reviews of UVC lights, I came across the idea of ozone generators. They work much more globally that lights, filling spaces the lights cannot touch effectively. Both types of units are dangerous and have to be used with caution. I've been burned by UVC lights in the operating room with tidbits of exposed skin. And ozone is tremendously harmful to life, not just microbes. In particular for humans, toxic for lungs. So you need remove plants, pets and people from your home.So I bought this unit in cold weather so opening windows was out (I had storm windows on anyway). With a bit more research I found that the ozone breaks down over time. Depending on how much you generate determines how long before it is safe to reoccupy. However that is hard, and I found recommendations that 4 hours after using generator is a very conservative safety margin. Thus it was easy to simply use for the maximum time either whole house or per room and add 4 hours and not bother with airing out the rooms or house.Easy to use. Love the mechanical timer, a simple old fashioned dial just like a kitchen timer. No delay before starting so be prepared to leave the house immediately. There is a distinctive smell after using that in my experience lasts about one day at most. Not an unpleasant smell at all, smells clean. Not unrelated to positive ion generators I think. Good value, and I read tons of positive reviews here.As a huge bonus, it kill spiders!!! Other insects as well presumably.
