Indoor Air Quality: What's in the air your breath? Get a quick glimpse of some of the most important ways to protect the air in your home by touring the Indoor Air Quality (IAQ) House. Room-by-room, you'll learn about the key pollutants and how to address them. Explore common air quality issues among the rooms below: Living Room Bathroom Bedroom Kitchen Basement The Living Room A living room is usually a well-used area of a home and may harbor indoor pollutants. It is important to ventilate properly, keep secondhand smoke outside of the house, and vacuum and dust regularly. Pet Dander and Hair Pets can trigger allergy and asthma attacks due to dander and hair. Keep them out of the sleeping areas, and away from upholstered furniture, carpets, and stuffed toys. Vacuum and clean carpets, rugs and furniture often. Learn more about Pet Dander and Hair Secondhand Smoke Secondhand smoke from cigarettes, cigars and other tobacco products can trigger asthma and other respiratory illnesses especially in children. To help protect children from secondhand smoke, do not smoke or allow others to smoke inside your home or car. Learn more about Secondhand Smoke Carbon Monoxide Fireplaces and leaking chimneys are sources of carbon monoxide. Ventilate rooms that have fireplaces, make certain the flue damper is operational and fully open when in use, and ensure the chimney is properly sealed. Learn more about Carbon Monoxide The Bathroom Mold is a type of fungus that grows in damp environments. It can cause a variety of health issues, including respiratory problems, allergies, and infections. If you suspect that you have mold in your home or business, it's important to get it tested as soon as possible. At US Environmental Testing LLC., we offer comprehensive mold testing services to detect the presence of mold and assess its potential hazards. Our team of experts will work with you to develop a plan to address any issues and ensure that your space is safe and healthy. Bedroom A bedroom often contains materials that collect dust. It is important to clean bedding and other fabrics, and vacuum regularly. Dust Dust mites can trigger allergy and asthma attacks. Dust mites are everywhere especially on pillows, blankets, carpets, upholstered furniture and stuffed toys. Dust and vacuum your home regularly, wash bedding, and use allergen-proof mattress and pillow covers. Learn more about dust mites. Kitchen A kitchen has appliances that may leak gases, and often contain chemicals for cleaning or removing pests. It is important to properly maintain and ventilate appliances, and safely store chemicals Kitchen Volatile Organic Compounds (VOCs) Common household cleaners, often placed under the kitchen sink, release Volatile Organic Compounds (VOCs), when used and stored. Store household products that contain chemicals according to manufacturers’ instructions and keep all products away from children. Consider purchasing cleaners without VOCs. Learn more about VOCs. Pesticides Pesticides used to rid homes of rodents, termites, insects, and other pests, can irritate the eyes, nose, and throat; damage the central nervous system and kidneys; and increase the risk of cancer. Don’t leave food out, and if you must use pesticides, ventilate during and after use and follow directions to limit exposure. Use non-chemical methods of pest control when possible. Learn more about Pesticides. Basement Carbon Monoxide To help prevent carbon monoxide exposure, make sure appliances such as gas stoves vent to the outside whenever possible and that all appliances are properly installed, used and maintained. Learn more about Carbon Monoxide. Mold Basements can be damp. Install a properly sized dehumidifier to help keep your basement at an appropriate humidity level and reduce the potential for mold. It is important to dry water-damaged areas and items within 24-48 hours to prevent mold growth. Learn more about mol d. Radon Radon is the leading cause of lung cancer among non-smokers in the U.S. It is a naturally occurring radioactive gas that can enter a home through cracks and openings in floors and walls that are in contact with the ground. Testing your home is simple and inexpensive. Learn more about Radon. For Existin g Homes: Test for radon — testing is the only way to know if radon is in your home . Do-it-yourself test kits are convenient and accessible, or you may choose to have a professional test your home. If the test result indicates your radon level is too high (greater than 4.0 picocuries per liter air, pCi/L) a qualified radon service professional can install a radon mitigation system. For New Construction: Radon-resistant new construction (RRNC) draws radon from the soil and vents it through a pipe to the roof, preventing its entry into the house. This technique uses common materials and building skills. RRNC costs less than retrofitting a similar radon reduction system after the house is finished. New home buyers should ask their build to include RRNC features. All new homes, even new RRNC ones, should be tested for radon. Learn more about radon-resistant new construction. Learn about the Indoor airPLUS program and the Construction Specifications, which includes radon. Blog Ph:630-915-9434 Request Quote
