Dry hydrogen peroxide (DHP) technology, developed by Synexis, is gaining traction outside medical settings and making its way into residential spaces. Unlike typical hydrogen peroxide solutions, DHP is not a vapor but a true gas produced by specialized machines. These machines, currently offered by Synexis, use a photocatalytic reaction to generate DHP from oxygen and moisture in the air, effectively neutralizing harmful pathogens like bacteria and viruses. The advantages of DHP over conventional disinfection methods are numerous - it can be used in occupied spaces, requires lower concentrations, and covers a larger area, making it highly efficient. The Synexis Sphere, a leading DHP-generating machine, offers comprehensive air purification by combining DHP with UV light and particle filters. Despite concerns from competitors about efficacy and EPA/FDA registration, DHP has shown promising results against various pathogens, including the highly transmissible Delta variant. For homeowners, the main drawback currently is the lack of a residential model, although products like the Synexis Sphere designed for medical facilities can be adapted for home use efficiently. With its cost-effectiveness, wide coverage area, and low maintenance requirements, DHP technology presents a positive outlook for enhancing indoor air quality in residential settings.
