  • UV Air Cleaners Work

While built-in air filters are good at removing dust and dirt particles from the air, they are largely ineffective at removing micron and submicron-sized microbes. Ultraviolet (UV) air cleaners, on the other hand, use ultraviolet light to kill bacteria, viruses, mold, fungi, allergens, and other organisms without any filtration. These cleaners make the indoor air in your Fort Myers, Florida, home more hygienic and breathable.

What Is UV Light? 

Ultraviolet light is a type of light that’s invisible to the human eye due to its short wavelength. It’s a form of electromagnetic radiation that causes burns and destroys cells. The sun contains UV light naturally; UV air cleaners produce ultraviolet rays on their own.

How Do UV Air Cleaners Work?

With a UV air cleaner, a powerful fan forces air through a high-quality filter into the UV purifier. The machine then circulates the air through a small chamber, where it comes into direct contact with ultraviolet light. The duration of this exposure varies depending on the model of your machine but usually lasts less than a second. The UV rays kill the microbes and other contaminants by destroying their cells. For some types of pathogens, the UV light disrupts their DNA and inactivates, rather than kills, them so they are no longer capable of causing harm.

Depending on the model, the air from the UV chamber might go through one more round of filtration before being circulated around your home.

Is it Safe and Effective?

UV air cleaners kill up to 99 percent of bacteria. Their efficacy depends on the UV rays’ intensity, the air’s proximity to the rays, and the duration of exposure. 

Leakage of UV rays from these machines can be extremely dangerous. Our models, however, have a UV shield to guard against this concern.
