If you are an allergy sufferer, you may have heard that a UV air purifier can help with your condition. This is certainly true. Molds, fungi, spores, even dust mites and their feces can all be removed from the air. In addition to this, an ultraviolet light air purifier can help keep you from coming down with common illnesses such as a cold. Here is an overview of how a UV air purifier works, and certain issues you should be aware of.
The most important feature of a UV air purifier is the bulb. Air passes though the UV light and any bacteria, mold, fungus, virus or other living material is subjected to a lethal dose of UV light. Don't worry, this isn't harmful to people, but is deadly for small life forms. You want to find a bulb that puts out UV light rays in a very specific spectrum to ensure that they are being as effective as possible at killing and cleaning organic material out of the air. You also want to make sure that the lifespan of the bulb that goes in the unit is at least a year. UV air filter bulbs can be expensive to replace and if you are churning through one every three months this can add up really quick.
In addition to directly eliminating harmful particles from the air, UV light air purifiers work by starting destructive chemical reactions in the indoor air pollutants. The light will convert molecules of oxygen and water in the air into ozone and hydroxyl along with hydrogen peroxide. These airborne molecules then react with the pollutants, destroying and decomposing them into their harmless components, usually water and carbon dioxide.
You should be aware that a wide band bulb can create too much toxic ozone and will cause problems beyond the ones that it was trying to fix. A quality UV air purifier will have a limited UV spectrum and minimize the amount of ozone that is produced. These high quality units will use UV light at an effective wavelength to generate hydroxyl particles.
This should give you a basic understanding of how a UV air purifier works and why one can be beneficial to you. They have many benefits for removing and destroying allergenic materials. Anywhere that you have these kinds of pathogens is a great place for a UV air purifier.
