When Are UV Germicidal Lights Advisable?

It is not enough that you maintain comfortable temperatures throughout the year if you wish to live in the truly comprehensive comfort that we believe you deserve. You must also take any necessary steps to ensure that your indoor air quality is high, as well. This can be rather tricky, as there are so many potential problems which may set back the quality of the air throughout your home. The good news is that the IAQ specialists on our staff are here to help. One option to consider, in certain circumstances, is the installation of UV germicidal lights in Fresno, CA. Read the following post, and contact Donald P. Dick Air Conditioning if you think that a UV air purifier is what you need in your home.

How UV Germicidal Lights Work

To understand when it is appropriate to use UV germicidal lights, you must first have a basic understanding of how they work. UV germicidal lights are installed directly into your air ducts, typically by the air handler, where all of the air circulating through your HVAC system will be treated. The lamps emit small amounts of UV (ultraviolet) radiation, which are completely safe for residents in the home, including any babies, pets, or elderly persons therein. For biological pollutants, though, the effects of the UV lamps are devastating. Such entities, including viruses, mold spores and bacteria, are effectively destroyed by the lamps’ rays and rendered incapable of reproduction.

When to Use a UV Air Purifier

UV germicidal lamps should not be used in place of an air filtration system, or electronic air cleaners, as they do not remove airborne pollutants—such as dirt and dust—from the air. However, if you have had issues with mold taking root in your home, or if you have allergy, asthma or other respiratory complications, then they are advisable. Biological pollutants such as these are often too small to be filtered from the air. Even if they are, they can continue to reproduce in the filter or air cleaner if not destroyed. The use of a UV germicidal light system eliminates such risks.
