3).Ī 2020 study conducted by Boston University and Signify Research found that UV light with an irradiance of 0.849 mW/cm2 partially inactivated the coronavirus after 0.8 seconds and reduced it to below detectable levels after 9 seconds for dried and 4 seconds for wet samples (Ref. This inefficiency poses a problem because behavior changes dramatically with a “disinfected” object and could lead to an increase in disease transmission (Ref.
UVC LIGHT AIR PURIFIER PORTABLE
Home or consumer portable air cleaners with UV light lack quality control processes and high intensity UV bulbs leading to a lower than the marketed effectiveness. Accurate use includes administering the right kind of UV light, the correct dosage, and UV lamps quality control (Ref.
Yes, UV-C light can purify air - BUT UV-C light must be used accurately to be effective at inactivating microorganisms. Studies have shown that with low doses of 222 nm far-UVC light, H1N1, and other human coronaviruses are rendered inactive after exposure – 90% after 8 minutes and 99.9% after 25 minutes (Ref.
UVC LIGHT AIR PURIFIER SKIN
Because of this, far-UVC light does not penetrate human skin or eyes offering a safer UV light for disinfection. Far-UVC light has a wavelength of 207 or 222 nm with a very limited penetration depth (a few micrometers). Recent research has explored Far-UVC light as an inexpensive way to reduce disease transmission in public places (Ref. UV-C light, the 3rd type of UV light, is blocked from the earth’s surface by the ozone layer and water vapor in the earth’s atmosphere (Ref. The sun emits UV light making up about 10% of the sun’s light - 95% UV-A and 5% UV-B light (Ref. UV light is a type of electromagnetic radiation that falls between visible light and x-rays on the electromagnetic spectrum (Ref. A UV light sensor and LED lights indicate if the unit is supplying sufficient UV-C light to improve efficiency and reduce particle build-up on the light bulbs.Reflective surfaces in the disinfection area increase irradiance of the UV-C light and improve efficacy.Dual inlets feature electrostatic cleanable pre-filters to remove large particles reducing particle build-up on the bulbs and reflective surfaces to help prevent a reduction in effectiveness.A safety interlock prevents the unit from working if the lid or filters are not in place.3rd party tested for UV-C and ozone readings.Leakproof UV-C light cabinet with light leak reduction design features (refer to brochure for more information).Uses UV-C light with shorter wavelengths to improve penetration of microorganisms.Adjustable airflow control: 300, 375, or 450 CFM.This system was stringently tested both in the Sentry Air Systems’ factory and by a 3rd party lab to ensure UV-C and ozone safety.
