Improving Home Air Quality During Winter
Air quality during winter is a cause for worry because the home is sealed up during that period in order to preserve heat. The flow of air from the exterior to the interior is thus interrupted. Hence, any chemical build-up inside the home during that period cannot be evacuated. They can easily reach toxic levels. The worst of it all is that most of these toxic substances bear no smell and the air quality could have fallen dramatically without anyone even noticing. Given that most North Americans spend at least 90% of their time indoors during winter, the effect of poor air quality on their health could be considerable.
Symptoms of decreasing air quality
If there are more chemicals in the atmosphere of the home, then there is likely to be some impact on the health of the occupants. Some symptoms include: frequent headaches, nausea, drowsiness or other problems that disappear once you leave the house.
Sources of Emissions in the home
The first source of toxic substances is furniture, carpets and upholstery that give off volatile substances. These substances are thought to cause irritations of the eyes, nose and throat as well as breathing difficulties. They are also suspected to cause cancer in humans. A second source of toxic chemicals is the wood stove or fireplace. These can give off poisons such as carbon monoxide and formaldehyde.
How to reduce chemical build-up in the home
There are many steps that can be taken to reduce toxic substances in the indoor atmosphere:
(i) Avoid purchasing new carpets or furniture during winter unless they bear Air Quality labels
(ii) Clean wood stoves and fireplaces regularly so that they do not emit smoke. Consider professional help every now and then to ensure that they are working properly.
(iii) Install High Efficiency Particulate Air (HEPA) Filters in the vacuum cleaner or the air cleaner. HEPA filters will effectively capture particulate matter in the air.
(iv) Consider installing mechanical ventilation systems.
(v) Open the windows regularly, even if it is for a limited tiME
