An air purification system with UV (ultraviolet) light plays a crucial role in improving indoor air quality by targeting and neutralizing harmful microorganisms. UV light, particularly UV-C, is effective at destroying the DNA and RNA of bacteria, viruses, and mold spores, rendering them inactive and unable to reproduce. When integrated into an HVAC system or used as a standalone purifier, UV light enhances overall air cleanliness by reducing airborne pathogens that traditional filters may miss. This technology is especially important for people with allergies, asthma, or weakened immune systems, as it creates a healthier, safer living environment by minimizing the risk of illness and allergic reactions.
