Yes! DHP is produced at5-25 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 3% solution of H2O2 found in a medicine cabinet. DHP concentrations fall far below acceptable safety limits for human exposure established by the Occupational Safety and Health Administration (OSHA).
