Air Quality Tips

Air pollution can sometimes be worse inside your home than it is outside. As you increase the air-tightness of your home, you must also keep air quality in mind. Recognize sources of pollution in your home

Air-borne pollutants are either biological (mould, dust mites, pollen, animal dander) or originate from other sources (gases or chemical particles released by furnishings, carpets, construction materials, unvented appliances, renovation activities including dust from lead paint, poorly-maintained heating systems, humidifiers and dehumidifiers).

Your heating system All heating systems and other equipment that burn fuel give off combustion gases. Occasionally, a portion of these gases might ''spill'' into the home instead of exhausting to the outdoors. If you suspect a problem, ask your fuel or equipment supplier to check for combustion spillage and make any recommendations necessary, such as installing a combustion air supply or upgrading or replacing equipment. You should have a working carbon monoxide detector. They are now mandatory in many situations.

Wet firewood brought into the home to dry can both introduce and support mould growth. Wood should be stored outside until needed.

Is your home well ventilated? If you are planning to make your home more air-tight, be sure to check into the need for improved ventilation. A mechanical ventilation system is a must for any well-sealed home. A heat recovery ventilator goes a step further and provides more energy-efficient ventilation by reducing heat loss as outdoor air replaces indoor air.
