The Future of Indoor Air Quality: A Call for Government Incentives in Canada
Indoor air quality is a significant concern given our increased time spent indoors, especially with the ongoing challenges of maintaining air purity during a global pandemic. In Canada, the question arises: Are there any government incentives or programs that promote the use of HEPA filtration for indoor air quality improvement?
Given the current state of HEPA filtration technology and its application, the industry must rise to the challenge. Traditional HEPA filters, which were often designed for short-term use, proved to have limited long-term effectiveness. Moreover, the cost and design of these filters often hinder their widespread adoption. This article explores whether government incentives can encourage the use of more effective filtration systems, such as high-pressure hyper HEPA filters, to improve overall indoor air quality.
Critiques of Traditional HEPA Filters in Canada
The traditional HEPA filters, though widely used, have faced criticism for their limited long-term effectiveness and high cost. Some users report that these filters, when dirty, no longer provide substantial filtration benefits. In the past, such filters in forced-air heating and cooling systems were similarly ineffective, as they would pull in only a small amount of return air, while the rest bypassed the filter, negating any benefits.
A specific example from a Canadian user highlights the issues: "[The policy makers] designed it for a very short lifetime, and it worked by pulling in a small amount of return air, letting the rest carry right through. So I paid a whole bunch of money for something that when it got dirty would no longer filter."
The effectiveness of these filters has raised questions about the value they bring to maintaining indoor air quality. However, advancements in filtration technology have brought about more effective options, such as specialized portable units, like IQAIR PRO, which filter out even COVID-19 viruses. These units push a bit less air through them as they get dirty, ensuring that the air that passes through remains highly filtered.
Advanced Filtration Systems and Their Limitations
The most advanced filtration systems, including high-pressure hyper HEPA filters, can effectively remove even the tiniest particulates, including viruses. However, the industry must strive for further improvements. Traditional HEPA filters, despite their advancements, are often designed to handle a limited volume of air. This limitation can be circumvented with more sophisticated filtration systems that force all air through them in one pass with high-pressure fans. These systems provide better filtration efficiency and are less prone to bypassing air.
Another critical factor is the removal of odors. A combination of HEPA filters and activated carbon layers is necessary to eliminate odors effectively. Even well-designed HEPA filters can allow sulfur particles, common in urban areas due to highway pollution, to pass through. These particles can enter the bloodstream and penetrate the blood-brain barrier, raising health concerns. Effective filtration systems must address these issues to provide comprehensive indoor air quality solutions.
The Role of CO2 Levels in Indoor Air Quality
Carbon dioxide (CO2) levels also play a crucial role in indoor air quality. In 1949, the concentration of CO2 outdoors was at 320 ppm, while today, it has risen to 420 ppm. In Canada, the government has set a limit of 1000 ppm for indoor spaces. For a person breathing for two hours in a closed kitchen or living room, this CO2 level can be easily reached. To mitigate this issue, windows should be kept open, and outdoor air should be filtered into the house.
The challenge is to balance between CO2 elevation and pollution from dust, dander, and other indoor particulates. Given the difficulty in regulating these factors, the industry must step up to provide better solutions. Rural settings may also face challenges, as open air and natural ventilation are less effective in reducing indoor pollution.
A Call for Government Incentives
Given the critical nature of indoor air quality, it is essential for the government to incentivize the adoption of advanced filtration systems. Policies that encourage the use of high-pressure hyper HEPA filters and the integration of carbon layers for odor removal can make a significant impact. Such incentives could include tax breaks, subsidies, and grants for homeowners and businesses to upgrade their air filtration systems.
The Canadian government could also consider regulating the design and performance standards of air filters to ensure that they meet specific criteria for effectiveness and efficiency. By setting these standards, the government can push the industry to innovate and provide better solutions for indoor air quality.
Moreover, public awareness campaigns and educational programs can inform citizens about the importance of air filtration and the benefits of advanced systems. These initiatives can also provide guidance on how to achieve a balance between CO2 levels and indoor pollutants.
As the world continues to grapple with the challenges of indoor air quality, the government must play a pivotal role in promoting and incentivizing the use of advanced filtration systems. By doing so, Canada can take a significant step towards creating healthier living and working environments for all its citizens.
