| Air Purifiers Health Concerns Air purification can be crucial to your health and to the health of each of your family members. Studies conducted by the U.S. Environmental Protection Agency indicate that your exposure to air pollutants can be up to 100 times higher indoors than the outdoors. "Sick Building Syndrome" (SBS), a term many people are familiar with, costs North America more than $100 billion each year in health care costs, absenteeism, lost production time and lost revenue. Bacteria is also at the heart of SBS. Chemicals in carpets, household cleaners, furniture and building materials all contribute to poor IAQ, as do dust mites, animal dander, cat saliva and mold. To kill the harmful bacteria caused by these pollutants, it might be a good idea to "clear the air" with air purification products. Benefits of Air Purification It is estimated that 50% of all illnesses are either aggravated by, or caused by poor indoor air quality. So, clean indoor air is important. Air purification products provide a variety of methods to help contribute to a healthier living environment. One such method is through the use of ultraviolet (UV) lights, which inhibit the growth of biological contaminants. Through a process known as photolysis oxidation, UV rays help decompose air contaminants. When installed in conjunction with your home comfort system, these air purification devices can eliminate a good portion of the organisms in the treated area. At the same time, they clean the air filter surface, creating an environment that inhibits biological contaminants from growing. |
| Efficiency Ratings SEER- Seasonal Energy Efficient Ratio. This is a system for rating the efficiency of cooling equipment. It is calculated by dividing the cooling capacity of a continuously operating air conditioner by the electric power input. The higher the SEER, the less you unit will cost to operate. Sound Ratings In recent years, HVAC equipment has not only gotten more energy efficient, it has gotten quieter. Although sound does not effect the efficiency of a unit, it can certainly affect your comfort. If your unit has a low sound level, (you and your neighbors) will hardly notice when it is operating. Db - Decibel. A term to describe the relative loudness of a sound. Typically, heat pumps and air conditioner are between the sound of a human voice (70 db) and a blender (88 db). SRN - Sound Rating Number. A unit based on ARI tests. Average sound rating range from 74 to 80 db. The lower the SRN rating, the quieter the unit. General Industry Terms HVAC - Heating, ventilating and air conditioning. This term applies both to the heating and cooling industry and to the products they manufacture. |
