UV Light Air Purification

Homes would benefit greatly from the use of a UV Light Air Purification system for many reasons. It’s a fact: The air inside your home can be just as polluted, if not more tainted, than the air outdoors. Tobacco smoke, fireplaces, kerosene heaters, wood-burning stoves, household cleansers and paint are all common sources of indoor air pollution.

If you have a central or forced-air heating and air conditioning system—one that moves air to the rooms inside your house through a set of ducts—you may be relying on the air filters (which are part of your HVAC system) to protect you and your family from the harmful contaminants that circulate through your home’s air.

And it’s true—these filters can be very effective at removing many airborne toxins (such as vaporized chemicals) that would otherwise make their way back into the air stream. The problem is, most air filters only remove particles up to a certain size.

What is UV Air Filtration?

Furthermore, the ductwork inside your home may be dark and damp, which is the ideal environment for mold and mildew to multiply and thrive.

When your furnace is operating, the fan spreads these spores throughout your home. To make the situation worse, if you keep your windows shut year round—at least throughout the summer and winter months while the air conditioner or furnace is on—very little “fresh” air is brought indoors.

Instead, the same old stagnant air is re-circulated over and over again inside your home. Breathing this air can lead to upper respiratory illnesses and allergic reactions, and aggravate problems with asthma and lung disease.

To protect your household from microscopic contaminants, we recommend having an additional, and separate, UV light air purifier system in place.

What is UV Air Filtration?

UV (ultraviolet) light air purifiers are a new form of technology to remove airborne microbial particles and significantly improve indoor air quality.

The airborne particles are destroyed using rays of ultraviolet light, which incinerate them as the pass through it.

A UV air purifier is not designed to be a replacement for the mechanical air filter you already have with your home’s forced air system or your HEPA filter attachment—both of which are effective at stopping a majority of the larger particles—but is rather a supplement.

"UV light air purifiers kill the small, living microbes that are not caught by the mechanical air filters—filling in the indoor air quality gap".

Ultraviolet purification lamps can be easily installed in any existing forced air system. Usuallythe lamps are either placed inside the main supply duct or mounted on the return duct of a central heating or air system.

In general, we recommend attaching the UV lamp where it is downstream of the air conditioning coils, on the supply side of the heating or cooling system.

This is where there is likely to be condensation on the air conditioning coils or standing water in the drip pan below, so placing a UV lamp there will destroy any mold, mildew or bacteria that are collecting and reproducing.

You may want to place additional UV lamps on the return air ductwork to clean the air as it passes through the system.

You will notice a marked difference in the quality of the air circulating through your bedrooms, living room, kitchens, or wherever you need it most.

An added bonus is that UV air filters require little maintenance and are very inexpensive to operate—no more than just pennies a day.

How UV Light Purifiers Work

When you hear the words “ultraviolet light” what probably comes to mind is a bad sunburn. In a nutshell, that is what UV light air purifiers do to microorganisms: In effect, they get a very bad case of sunburn.

"In technical terms, what happens is the UV light air cleaner uses two different wavelengths to break through the cell walls of microorganisms and cause photochemical damage to their DNA and RNA (genetic code)".

Once this happens, the microbes are no longer able to reproduce and thus cannot cause illness.

For instance, if a family member has a cold or influenza virus and he or she sneezes in one room of your house, your home’s ventilation system will transport those germs and distribute them throughout your house, in about a half hour’s time on average.

However, if you have a UV air purifier attached to the ventilation system, those germs will have no escape route.

They will be forced to come in contact with the radiation emitted from the UV lights. When they do, their reproductive capabilities will be ended and they will be rendered harmless.

Very pleased with Dan Pelletier who replaced the coils in my upstairs air conditioning unit. He was very professional, polite, thorough, and even vacuumed my stairs when debris from my old unit fell on the carpet. I highly recommend Dan and would request him again.
