Yes! DHP is deployed at 5-25 parts per billion. This produces extremely effective microbial reduction at incredibly safe levels of H2O2. A single Synexis unit would have to run continuously for 2.5 years to reach the concentration of 1 droplet of a 3% aqueous solution of H2O2. DHP concentrations fall far below acceptable safety limits for human exposure established by the Occupational Safety and Health Administration (OSHA).
