View Full Lab Test ReportIs It Safe?
Yes. BioShieldUV™'s ozone output measures at 0.014 ppm, well below every relevant safety standard.
Remember: Not every UV-C system on the market operates at a safe wavelength. If you are evaluating other brands, check to see if they use 185 nm lamps, as these generate ozone as a byproduct and are not safe for residential use.
