Air quality is an important factor in our health and wellbeing, and HEPA filters can be a great way to improve it. HEPA stands for High Efficiency Particulate Air, and these filters are designed to capture particles as small as 0.3 microns, such as dust, mold, bacteria, and even viruses. While HEPA filters can help reduce the amount of contaminants in the air, they are not a complete solution for improving indoor air quality. In addition to using a HEPA filter, there are other steps you can take to improve your indoor air quality.
Increasing the amount of outside air that is pumped into the building can help reduce pollutants such as mold, pollen, and exhaust gases. You can also use an air purifier that combines a HEPA filter with an activated carbon filter or an ionizer to capture particles that most air filtration systems cannot contain. Studies have shown that using air filters can reduce indoor fine particle concentrations by up to 60%. Filtration was also associated with a 9.4% increase in the reactive hyperemia index and a 32.6% decrease in C-reactive protein.
When HEPA filters were used during the winter investment months, only five percent of PM2.5 in outdoor air contributed to indoor air quality, compared to 28 percent when HEPA filters were not in use. The last filter consisted of a high-efficiency particulate air filter (HEPA), which filtered 70% of 0.3 μm particles and 95% of 1.0 μm particles. In addition to providing general information about the types of pollutants affected by air filters, this document discusses the types of air cleaning devices and technologies available, the metrics that can be used to compare air cleaning devices, and the effectiveness of air cleaning devices for eliminating indoor air pollutants and improving health markers. Air purifiers can also neutralize some of the threat posed by air pollution and indoor activities. Learn more about a new air cleaner technology that destroys pollutants, rather than simply trapping them like a HEPA filter. As you can see, there are many ways to improve your indoor air quality beyond just using a HEPA filter. Increasing the amount of outside air pumped into your home, using an air purifier with mechanical filters such as HEPA, and learning about new technologies that destroy pollutants are all great ways to ensure your home's air is clean and healthy.
