Opening windows not the answer to indoor pollution

(NC)—We've all experienced it — that first gust of fresh spring air that spills into your home once you finally open your windows to make that stale "winter" indoor air feel less stuffy and revitalized.

This spring "purification" ritual does have short term ventilation benefits and helps to clear out the unhealthy air that's been circulating in your home. But experts in the field of indoor air quality quickly point out that simply opening your windows is a far cry from an ultimate solution to year-round indoor air pollution.

"I'm still amazed at the number of people who believe opening their windows will help solve their indoor air quality problems," said Jean Deslandes, of Venmar Ventilation, the country's leader in indoor air quality management. "One has to remember the air that enters the home through an open window is not filtered so it also contains harmful pollutants."

Indoor air quality has become more of a cause for concern than it was in the past since improved insulation and other energy-saving measures have meant poorer air circulation for many of our homes and buildings. "Today's homes can actually trap inside air pollutants and retain extremely high levels of humidity," added Deslandes.

More importantly, these indoor pollutants can have serious adverse effects on your and your family's health. Experts view indoor pollutants as one of the major culprits for the 160 per cent increase in asthma rates over the past 15 years.

So what can you do to protect your family from the harmful effects of poor indoor air quality? First off, opening windows may actually aggravate your situation. What happens when the temperature, pollution index or pollen counts are high? Pollen, pollution and other allergens are entering your home as your air conditioner wastes energy working overtime. So what is the optimal solution? According to the Ontario Lung association, effective and efficient mechanical ventilation is an important part of a healthy indoor environment.

Venmar's Whole-House HEPA Air purification system, the latest technology in indoor air management, offers the best solution to reducing indoor pollution by combining the efficiency of HEPA filtration and effective mechanical ventilation.

"The air purification system allows polluted air to exit and fresh air, filtered by HEPA filtration, to flow through the home," Deslandes added. "Its HEPA filter system traps up to 99.97% of .03 microns particles and can significantly reduce the number airborne particles in your home. It also allows excess humidity and dangerous mold spores, volatile organic compounds (VOC), and carbon monoxide that are not captured by filtration, to escape the home."

Licensed as a medical device by Health Canada, Venmar's HEPA series units substantially contribute to improving indoor air quality in dwellings and, at the same time may improve the quality of life of individuals with serious respiratory diseases. Individuals who acquire one of these specialized units under prescription may be able to deduct the purchase price from their income tax.
