Do UV Air Purifiers produce ozone?

Most of the Second Wind UV air purifier models have an ozone-free lamp that operates at a sole wavelength of 254 nm. The ozone-free lamps with 254 nm wavelength produce a strong germicidal effect and destruct the ozone. Few of the Second Wind UV air purifier models have an optional ozone generating lamp that operates at a dual-wavelength of 254 nm and 185 nm. The ozone lamps with dual-wavelength are required for some specific applications to oxidize organic compounds.
