Newer houses are constructed to avoid heat loss in the winter and heat gain in the summer — essentially “holding” the air inside. Trapping pollutants in homes is causing indoor air pollutant levels two to five times higher than the pollutant levels outdoors, according to estimates from The Environmental Protection Agency (EPA).
Indoor air pollution is one of the top environmental and health concerns in the country. From pollen, mold and dust to animal dander and tobacco smoke, these indoor pollutants can create asthmatic and allergic reactions. We spend up to 90 percent of our time indoors, and having clean indoor air to breathe is essential.
Sources of Air Pollution
Smoke
Tobacco smoke is one of the smallest of the irritants, and for years the EPA has reported a link between second-hand smoke and negative health effects. Many people can be affected by second-hand tobacco smoke from apartments or dwellings close to their own. But, the AHAM test covers a range of fine and ultra-fine particles from not only tobacco smoke but also oil smoke, diesel exhaust, smoke from wild fires and smoke from power plants.
Pollen
Pollen comes from trees, flowers and grass, and even opening a door can allow millions of these particles into a home. In addition, people and pets can bring pollen into the home from outside. Some people are particularly sensitive to the presence of certain pollen particles.
Dust
The dust found in your home and offices consists of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt particles and many other materials. The dust that is used for the AHAM testing is a very fine dust that has been described as a powder with a wide range of particle sizes.
Animal dander
People who are allergic to cats and dogs are actually allergic to the dander flakes pets shed. Dander can remain in a home long after the presence of the host animal.
Mold and mildew
Typically found in the shower, kitchen or basement, these sneaky plant spores also grow anyplace that’s warm and humid.
