While many air purification systems are effective at removing allergens like dust mites, pollen and pet dander, they’re not all able to get rid of bacterial and viral contaminants quite as effectively. For that, you need something that can actually kill the bacteria and viruses so that they will stop circulating throughout your home, and that’s exactly what UV germicidal lights can do. By choosing an air purification system that includes UV germicidal lights, you can ensure that your family won’t be subject to nasty germs flying around in the air all winter long.
