The general rule to resolve indoor pollution problems is:
• Removal of the Pollutant
• Dillute Air
• Improve Filtration
• Control Humidity
• If your house is over 50% relative humidity, a whole house dehumidifier is the solution. High humidity supports molds, bacteria, viruses, dust mites and rot. A dehumidifier can help manage these problems.
• Wood or alternative friendly flooring is recommended instead of carpet and vinyl which can cause certain respiratory problems when installed with glue.
• If your crawl space is vented the humidity could also be high in the crawl space causing many other problems. The solution is to seal the vents and install proper vapor barriers.
• Learn how to operate your heating and cooling system. Do not set the thermostat above 78 or below 68 degrees Fahrenheit. By setting indoor temperature too high or too low you can cause condensation to form in the wall itself. This causes rot, mold and paint to peel.
• Replace your ventless gas fireplace with a vented system. Open a window while in use and install a good carbon monoxide detector.
• Most homes have one dollar air filters which allow debris to flow in the air that you breathe. The solution is to invest in a high quality air filter that is able to trap dust and smaller particles.
This is a dirty air coil that over 90% of the air flows through before you breathe it. Do you really trust your $1.00 filter?
• A heating and cooling system is recommended to have room by room returns to keep house pressure equal or slightly positive. Do not buy a heating system with a central return. Central returns cause negative pressure and draw in moisture which can lead to more problems.
