Ultraviolet (UV) energy from the sun is used in nature to help cleanse outdoor air and to inhibit the growth of micro-organisms such as germs and bacteria. Ultraviolet Germicidal lights have been used indoors for many years as a trusted air purifying method in hospitals, labs, schools, nursing homes, office buildings, and other commercial and residential environments worldwide.

Your furnace provides a perfect environment for the growth and broadcast of germs, mold, bacteria, toxins and gases that cause unhealthy air conditions which are found in our homes. Your furnace is the collection point for re-circulating air in your home and is the ideal place to install an indoor air cleaning system to control harmful levels of indoor air pollutants.

The Environmental Protection Agency has found that indoor air is always 2 to 5 times and sometimes 100 times worse than the worst outdoor air. You may not be able to see, smell or touch it, but this air pollution is impacting the health of your family. Many recent environmental and medical studies conclude that indoor air pollution is a major cause of respiratory problems including asthma, allergies and is directly related to other chronic ailments that we suffer from. – www.4natureshome.com/uv_energy_UVV_ozone.html
