What is UV?
UV is a form of radiation with very short wavelengths, so short that the human eye is not able to detect them. This energy is called “ultraviolet” because its wavelength is shorter than that of the violet light – the shortest visible wave of light. It has three wavelength zones: the UV-A, UV-B and UV-C. The latter is being used for its germicidal properties for disinfection and has the shortest wavelength.
Wavelengths of the three zones.
- UV-A: 315 to 400 nm
- UV-B: 280 to 315 nm
- UV-C: 100 to 290 nm
UV light has many benefits and uses. You may have encountered some products that feature them such as UV saunas. The UV light in a UV-activated sauna allows the heat to be more evenly distributed so it’s more efficient than ordinary saunas. The same is true in UV air purifiers.
How Does It Kill Viruses, Bacteria and Molds?
You may be wondering how a UV air purifier is different from your typical air purifier in the market. How do they differ when it comes to killing bacteria? Well, unlike air filters that need to collect the pollutants in order to stop them from spreading, UV air purifiers uses UV light to kill them right away.
Ordinary filters or even the HEPA filters let pollutants pass through the unit and then keeps them secured in one place. UV air purifiers, on the other hand, are designed to immediately kill bacteria, mold, and viruses. UV kills their genetic core in order to prevent them from reproducing. That’s why they are also called germicidal cleaners which means “germ-killing” cleaners.
Ultraviolet radiation, in the right amount, is deadly to many living things including those that cause indoor air pollution. When these germs pass through the UV radiation, it immediately destroys them, neutralizing the damages that these pollutants cause.
Does Air Purifier with UV work?
UV light is widely used as a disinfectant in water and air. In the US and Canada, UV radiation is used for water treatment to kill bacteria and viruses. In Europe, UV is used commercially especially in the field of pharmaceutical and beverages. In air purifiers, it is used to sanitize air contaminants, viruses and bacteria.
According to Prof. David J. Brenner, UV-C light could kill bacteria and viruses and is safe for human skin. The UV-C spectrum has short wavelengths, too short that it cannot penetrate to human skin.
UV air purifiers do work but you need to be conscious of the brand and model that you choose. You don’t have to do all the research because we have already compiled a list of the best models available so you can compare them and decide which the best is for you. Choose those that have UV-C light.
