How does a UV purifier work? A UV purifier uses short-wave ultraviolet light (UV-C light) to destroy airborne pathogens and microorganisms like mould, bacteria, and viruses. The UV purifiers installed by Cross are attached to your current HVAC system. They are designed to keep the air in your entire home clean and fresh. The UV lamp is placed downstream of the air being pushed through your HVAC system and as the air passes through the light — invisible to the human eye — it alters the DNA of the particles entering your home and makes them inactive or destroys them.
