Is UV Light Safe to Smell? A Comprehensive Guide

The FDA has noted that ozone levels in UV products may be above the safety recommendation for humans, leading to an unpleasant odor after the cycle is over. However, this odor is not harmful and can be avoided by leaving the room during and after a cycle. Research conducted by Koziel has revealed that UV light can be used to eliminate odors. When UV-C light hits metals, electrons are ejected from aluminum and other metals.

This process is not hazardous within the system and any metallic odor that is perceived may be the result of ozone gas produced by UV-C lights. Koziel and his team designed a box with several filters and UV light, which is invisible to the human eye. Installing short-wave ultraviolet (UV-C) lights in heating, ventilation and air conditioning (HVAC) units, such as the coil box, can help reduce odors. After UV disinfection, the volatile organic compounds responsible for residual odors do not pose a danger to human health.

Therefore, it is safe to use UV light to reduce odors.
