UV
A UV air treatment device uses ultraviolet (UV) light to kill or neutralize microorganisms such as bacteria, viruses, and mold as air passes through the HVAC system. These devices can also help reduce certain airborne odors. They are commonly installed as a complementary air purification step, often used after media air cleaners in indoor air quality systems. UV treatment is most effective when paired with variable-speed furnaces or HVAC systems with constant airflow fans, as this ensures the light exposure is consistent and maximized. Some UV air treatment products, such as those with CLASS II Medical Ratings, meet high safety and performance standards for improving air quality.
