The most common types of household Allergens are biological contaminants. These household Allergens are living organisms, or were living organisms at one time, and contribute to indoor air pollution. Common household Allergens include bacteria, household mold, mildew, viruses, pet dander, dust mites, and pollen. These organisms come from many sources.
What Can Be Done To Reduce Indoor Air Pollution?
Some of the things you can do to reduce your family’s exposure to indoor air pollution.
- Dust mites, pollen, animal dander, and other household Allergens cannot be completely eliminated, but regular cleaning can dramatically reduce their numbers. Use a vacuum with a hepa air filter.
- Install an efficient furnace filter or air conditioner filter in your central heating and cooling system.
- Perform regular maintenance to your Heat Recovery Ventilator or Air Exchanger. This will insure that the filters are working properly and removing airborne Allergens from the fresh air entering your home. Indoor air pollution can be made much worse because of airborne Allergens entering through ventilation equipment.
- Basements are often damp. If required, use a dehumidifier to maintain humidity levels between 30 to 50 percent.
- Keep the humidity level of your home between 30 to 50 percent. Room Humidifiers and Whole House Humidifiers can help dramatically.
- Install and use Kitchen and Bathroom exhaust fans that are vented outside. Sometimes these fans get vented into attic spaces. These fans must be vented outside. Venting into your attic can cause humidity problems.
- Ventilate attic and crawl spaces to prevent moisture buildup.
- Clean and dry water-damaged carpets and building materials within 24 hours if possible to prevent mold and mildew growth.
- Vent clothes drier air to the outside.
- Have a professional inspect and clean equipment that uses or comes in contact with water. Heat pump and air-conditioning systems remove moisture from the air when cooling your home. This water settles into a drain pan and flows to a drain. If the drain pans are not sloped towards the drain outlet water can remain in the drain pan and mold and mildew can grow.
