With pollution on the rise, ultraviolet air purifiers have become increasingly popular over the last few years. In particular, the U.S Environmental Protection Agency has placed the ultraviolet air purifier on the “generally safe” list due to the fact that they do not emit any airborne allergens or irritants. However, if you have asthma or suffer from allergies, you may want to seriously consider an ultraviolet air purifier. An ultraviolet air purifier is especially useful for those who cannot use other types of air purification devices. The main reason is that ultraviolet light kills or removes almost all harmful allergens, irritants, and bacteria from the air. Inhaling the ultraviolet rays is often much more soothing than breathing in polluting outdoor air.
An ultraviolet air purifier is usually placed on the front of a home or other enclosed space, such as a work area or baby’s room. The purifying agent is contained within the unit and filters the air through ultraviolet radiation. The UV rays sterilize the particles in the air, making it safer for everyone to breathe. The sterilization also kills or removes microorganisms and pathogens from the air. Some pathogens and microorganisms can live in the air without being noticed, such as dust, pollen, and germs.
The UV sterilization method is extremely efficient, as the germ-killing ability is nearly 100 percent. Other UV air purifying products use UV radiation to kill microorganisms and destroy spores that could develop into dangerous fungi or molds. While some fungi and molds are naturally occurring, most are highly infectious. For example, mold spores can grow on non-porous surfaces and can be passed on from one person to another by sharing food, clothing, and household items. Many people with a mold problem do not even know that they have it. With ultraviolet sterilization, the mold-killing ability is turned on when the germ-causing organisms are exposed to UV light, resulting in fewer illnesses and less risk of developing serious health problems.
Another benefit of using ultraviolet air purifiers is the elimination of indoor air pollution. Virtually all of the dust particles and microscopic particles in the air are larger than 5 microns. This size distinction makes them invisible to the naked eye, which is why so many allergens are kept in the air without being noticed. But humans can’t see dust particles, and even if they could, it would probably be too small to be an important factor in causing symptoms.
There are two primary types of ultraviolet air purifiers available for sale. These are portable devices that can be moved around; usually they are in a case or carrying case. The other type is stationary, which must be attached to the ceiling. Either style can get rid of airborne pollutants. Portable devices can also often perform other functions, including filtration and ionization.
Ultraviolet air purifiers usually cost more than other options, but there are some models available on the market that are significantly less expensive. To protect yourself and your family from allergens and other pollutants in the air, consider investing in an air purifier. These devices are also helpful in removing harmful bacteria and pollen that can cause sneezing and allergic reactions. If you feel as though you are spending too much money for an air filter, consider purchasing a model that performs additional functions. Many are UV-powered.
