Learn More About Indoor Air Quality
Indoor Pollutants:
Air pollution is the most serious long-term health hazard in the indoor environment. By-products from combustion appliances and environmental tobacco smoke are the biggest contributors to indoor air pollution. Both of these sources contain multiple toxins, including carbon monoxide (CO), nitrogen oxides, volatile organic compounds (VOC), and fine dust particles, which are inhaled deeply into the lungs.
Dust is a result of construction and other activities. Smaller and lighter dust particles are more dangerous than larger, heavier particles because they remain airborne for longer periods of time, and they settle more deeply in the lungs. The sharpness and chemical activity of the dust particles affects the danger they present. A dusty environment also magnifies radon’s danger by providing a transport mechanism that carries radon into the lungs. Radon is a dangerous indoor air pollutant that comes from the ground through rocky soil.
Wood stoves, unvented kerosene space heaters, and cigarette smoke release fine hydrocarbons dust and volatile organic compounds (VOC) into the indoor air. The fine particles in smoke can penetrate deeply into the lungs and controverted to a variety of respiratory illnesses.
Moisture management:
Moisture in American homes causes billions of dollars in property damage and millions of cases of respiratory disease each year. Moisture condensation problems are common during both the heating and cooling seasons. Moisture condensation is an important issue and home for three reasons:
water leads to building deterioration by biological pests. These pests also create a threat to human respiratory health.
Water corrodes metal, dissolves glue, warps wood, and weakens mortar.
Water reduces the thermal resistance of installation and may permanently damage it.
