Скачать или смотреть Do Dust Free Active Air Purifiers Produce Ozone? - They Do NOT - UL 2998 Ozone Free

At the 2022 AHR Expo in Las Vegas, Josh Pulis from Dust Free talks about the changes they made to their Dust Free Active units to make them UL 2998 ozone-free.
Ionization at a certain level has the potential to create ozone via the electrical charge. At 12,000 volts is when ozone creation starts to happen through ionization. Ozone can also be created by UV lamps. Depending on the frequency and wavelength of the lamp, there can be some incidental ozone created. To fix this, they worked really hard to create a catalyst, UV lamp, and ionization that creates no ozone. Recently, they got the official validation for UL 2998. #Shorts #OzoneFreePurifiers #IAQ
