 polluted air intake is expressed as an extremely important and critical issue. another way to lower the concentration of indoor air pollutants in your home is to increase the amount of outside air that enters. most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the home. opening windows and doors when weather permits, operating window or attic fans, or operating a window air conditioner with ventilation control on will increase the outdoor ventilation rate. local bathroom or kitchen fans that exhaust outdoors remove pollutants directly from the room where the fan is located and also increase the outdoor air ventilation rate.
ıt is especially important that you take as many of these steps as possible when engaging in short-term activities that can produce high levels of pollutants, such as painting, removing paint, heating with kerosene heaters, cooking, or doing maintenance and repairs. hobby activities such as welding, soldering or sanding. you can also choose to do some of these activities outdoors if you can and the weather permits.

advanced designs of new homes are beginning to have mechanical systems that bring the outside air into the home. some of these designs include energy efficient heat recovery fans (also known as air-to-air heat exchangers).
ventilation and shading can help control indoor temperatures. ventilation also helps remove or dilute indoor airborne pollutants from indoor sources. this reduces the level of pollutants and improves indoor air quality (ıaq). carefully consider using ventilation to reduce indoor air pollutants where there may be nearby sources of outdoor pollutants such as smoke or garbage.

how is  polluted air suction made?
the supply of outside air is an important factor in promoting good air quality. air can enter a home in several different ways, including:
• through natural ventilation such as windows and doors
• via mechanical means such as outside air intakes associated with the heating, ventilation and air conditioning (hvac) system
• by infiltration, a process in which outdoor air flows into the home through openings, joints and cracks in walls, floors and ceilings and around windows and doors.
• ınfiltration occurs in all homes to some degree.
