The primary cause of home indoor air quality problems, according to the EPA’s Indoor Air Quality website,  are indoor pollution sources that release harmful gases or particles into the air. Other factors that can contribute to poor indoor air quality are inadequate ventilation, and high temperature and humidity. Sources of indoor air pollution include combustion sources, building materials and furnishings, cabinetry or furniture made of pressed wood products, household cleaning and maintenance products, as well as personal care products, and central heating and cooling systems and humidification devices. Outdoor air pollution sources including radon and pesticides can also contribute to poor indoor air quality.

When there is too little outdoor air entering a home, health and comfort problems can arise from pollutants accumulating. Many houses are designed to prevent air from entering the house, which can cause pollutant levels to rise. This can cause immediate effects such as eye, nose, and throat irritation, headaches, dizziness, and fatigue. Other immediate effects include symptoms of diseases such as asthma, hypersensitivity pneumonitis, and humidifier fever. There are also long term health effects that may occur years after exposure or after long or repeated periods of exposure.  These include respiratory disease, heart disease, and cancer.

One solution to this problem is to install mechanical ventilation devices, such as outdoor-vented fans and also air handling systems. Air handling systems use fans and duct work to remove indoor air and bring in filtered and conditioned outdoor air into the house.  Filters Fast offers an extensive line of air filters to keep the air in your house clean and pure. We also carry many quality air purifiers that circulate and purify indoor air.
