Low wavelength UV light is highly effective at killing viruses and bacteria, with studies showing it can eliminate 99.9% of COVID and is 95% effective against swine flu. Research indicates that it is safe for human exposure, as it does not cause skin cancer, sunburn, or eye irritation. Studies on both humans and mice have consistently shown no harmful effects even after exposure to heavy concentrations over time. Ongoing research aims to further investigate any potential long-term risks, but current evidence suggests that low wavelength UV light is a safe and efficient method for eliminating harmful pathogens in the air.
