Anything that settles is immediately destroyed by the powerful ultraviolet light inside
People who live in the desert might have excruciatingly high temperatures and militant dust storms, but there’s one thing that they avoid in that climate. I’m talking about toxic mold. It’s not that it’s impossible to have mold in your house if you have water damage, it’s just that there are very few spores in the air outdoors. In the deep south, you’re fighting an uphill battle because the spores are literally everywhere. You can see where mold grows on the outside of peoples’ houses, especially near the ground. It’s literally everywhere outdoors whether you can see it or not. And this is why it gets indoor and takes hold in homes that don’t have proper climate control. We run our air conditioners to keep indoor humidity down as much as we use them for air cooling. But with the best air conditioner that money can buy, you still have to be vigilant in your house. That means keeping your bathroom clean, especially your shower. The air conditioner needs help as well, since microbial growth can take hold on your wet evaporator coil inside your air handler. That’s why I had my HVAC tech install UV lights inside my air handler on opposite sides of my evaporator coil. Not only does the UV light help kill harmful particles in the air, they also prevent mold from growing on the evaporator coil. Anything that settles is immediately destroyed by the powerful ultraviolet light inside. They’re wonderful additions to central HVAC systems regardless of where you live. Maybe I wouldn’t use them in the desert, but I’d definitely keep my UV lights living anywhere else in the country.
