WHAT TO KNOW ABOUT AIR QUALITY Everyone is talking about clean air systems. Here's what you need to know so you're not left out of a really good conversation. UVS. A UVS System is an ultraviolet lamp that should be installed by a Genz-Ryan professional. It’s placed in the air ducts. This lamp reduces the amount of mold and fungi that develop. After installation, the only maintenance is to replace the bulbs when they burn out. The product claims to help reduce the chance of illness in a home. These are most helpful for allergy sufferers. Air Exchangers with HEPA Filtration. This device exchanges the air in your home with fresh outside air a few times a day. The outside air flows through a filter. Manufacturers have taken it a step further by offering HEPA FILTRATION— the same used in operating rooms. This product is also designed to reduce illness by improving inside air quality and helping allergy sufferers. One of the main functions of the air exchanger is to prevent condensation in the newer, more airtight homes. Filters need to be replaced about every six months.
