Pollutants can come from many different sources inside and outside the home. For instance, carpeting and upholstery release chemicals into the air. These pollutants circulate through ductwork, entering every room and living space. And if entilation’s inadequate, the pollutants multiply. High temperature and humidity also increase concentrations of some pollutants to learn more about air quality problems. Indoor air pollutants come in all shapes and sizes, but they usually fall into three main categories.
Pollen Dust Pet Dander
A common trigger of allergies and asthma, particles are most dangerous when they are small and easily inhaled into the lungs.
Gases and Odors
Chemical vapors from gas appliances, fireplaces, carpets, garages, cleaning products, furniture, paint, perfumes, pesticides and tobacco smoke Gases and volatile organic compounds (VOCs) can be released from materials used during the construction, finishing and furnishing of your home. They can also come from everyday household items like aerosol sprays, paints, cleaning products and air fresheners.
Biological Contaminats
Mold spores, dust mites, viruses, fungi, bacteria, yeast and algae, so known as bioaerosols, these contaminants are mostly organic and thrive in warm, humid environments. Like particles, they are a major cause of allergies.
