UV Lights: Can They Improve Your Home’s Air?

UV-LightIndoor air quality is important—there’s no question about it. Allergies and respiratory conditions like asthma affect millions of Americans every year, and the numbers seem to be increasing all the time.

Getting more “fresh” air from outside can be good or bad, depending on where you live. In most cases, the air outside will be significantly better than the air in your home. On the other hand, the air in some cities can be even worse than the air in poorly ventilated homes.

Either way, getting fresh air indoors is important—and you may have heard about UV lights as a possible solution. Does it work? Or is it just another one of those cheap gimmicks you see on TV infomercials?

The Environmental Protection Agency (EPA) has a word or two to say about it. In recent statements, this organization has cited indoor air pollution as a significant health risk for Americans, and has listed UV lights as an effective way to clean up your indoor air.

In short, the EPA tells us that the answer is yes: UV lights can improve your home’s air.

So how does it work?

There are many microorganisms and contaminants (mold, bacteria, other organic compounds) which do not like UV light. In fact, they die when exposed to a sufficient amount of it.

If this is the case, you might think that opening the curtains and letting the sunlight though will have the same purifying effect, since sunlight contains UV rays. Unfortunately, this isn’t the case. The type of UV rays that are deadly to airborne contaminants are largely blocked by the earth’s atmosphere.

Fortunately, however, that type of UV light can be generated by special lights installed in your HVAC systems. It’s a combination of technologies that circulate purifying UV rays throughout your home’s air and render the environment inhospitable to unwanted contaminants—yet perfectly hospitable to people and pets.

UV lights don’t work as well on their own. It’s best to combine them with a good quality air filter and have them professionally installed to work in tandem with your existing HVAC appliances. The EPA states that UV lights are not a standalone solution for indoor pollution, but are a very effective component of your clean indoor air strategy.

One of the main reasons for this is that UV lights, while fatal to microorganisms, do not actually purify or freshen the air by removing impurities such as dander, dust or tiny microorganisms that have succumbed to the power of UV light. That’s why a good quality air filter is needed. We need a way to kill the microorganisms (UV light), but also a way to freshen and purify the air (filters, ventilators, air conditioners, etc.).

Seeing the light

UV lights are a safe and effective technology. They will be used more and more as more people wake up to the risks of indoor air pollution, and the solution that UV lights represent. Many HVAC specialists already offer high quality UV lights, and are able to expertly install them as a part of your existing HVAC system.

The result? Cleaner, fresher, healthier air for you and your family.
