UV Air Sanitizers

Using UV light to kill germs is not new technology. It was first used in France in 1909 to disinfect the water system and is now used in hospitals, commercial establishments, and private homes.

How UV Light Kills Bacteria

UV light is able to kill bacteria in the environment because of its ability to penetrate them and change their structure. After being exposed to the light, the bacteria is rendered sterile. If they are not able to reproduce, they die.

Indoor Air Quality and Health Issues

Many of us live and/or work in environments that don't get a lot of fresh air. The fact that today's homes are better insulated is an improvement when it comes to saving on our heating bills, but it also means that we are more likely to be exposed to microorganisms that get trapped indoors.

In this type of environment, we are more likely to become ill from airborne viruses. The increased incidence of asthma has been linked to lack of ventilation and breathing "stale" air.

Furnace Filters

The sanitizer does not perform the same function as a furnace filter. The filter is designed to deal with hair and dust. This will help the building's occupants to breathe a a bit easier, but the air quality can still be improved.

UV Air Sanitizers Improve Air Quality

When one of the UV air sanitizers on the market is installed in a home, office, or other type of commercial building, the device emits a light that cleans the air and reduces the number of microorganisms present.

An air sanitizer that uses UV light will help to kill the following contaminants:

• Mold
• Viruses
• Dust Mites
• Bacteria

Installing a Sanitizer in Your Heating System

One type of UV air sanitizer is installed in the return air duct of a heating or air conditioning system. You can perform this function yourself or have a contractor do the installation for you. Ask the company you bought the unit from how often you will need to change the bulb.

If you are told to change it once a year, mark the date on your calendar so you can make an appointment to have it done when your furnace or air conditioning system is inspected. You will also want to be sure to ask about a warranty on the unit you are considering.

The bulb may need to be cleaned every few months. You will need to avoid touching it with your hands, since this will reduce the level of UV output the bulb will give off. The bulb will should be removed, cleaned with alcohol, and then replaced.

Tabletop Units

Not all UV air sanitizers need to be installed to your heating or air conditioning system. You can place a tabletop unit in your office space, bedroom, or anywhere you would like to have the health benefits of cleaner air.

These models are compact and affordable. They are energy-efficient as well; some of them use less energy than a 25-Watt light bulb. Choose one that with a sturdy design that is not likely to tip over easily.

Plug In Air Sanitizers

Another economical choice when it comes to UV air sanitizers is a plug-in style. Simply place it in an electrical outlet to improve the air quality in any room (or part of a room) that you like.

Depending on the model you choose, this type of unit may also destroy odors. This means it would be a good choice for your kitchen, bathroom, baby's room, pet areas, etc.
