Improving Indoor Air Quality: The Role of Air Filters & Air Purifiers

If you're concerned about the quality of air inside your home, you're not alone. Indoor air pollution is a growing concern for many homeowners, especially those with allergies or respiratory issues. Fortunately, there are steps you can take to improve the air quality in your home, starting with your HVAC system.

One of the most important components of your HVAC system is the air filter. Air filters help to trap dust, pollen, and other pollutants, preventing them from circulating throughout your home. But with so many different types of air filters on the market, how do you know which one to choose?

Here are some tips to help you choose the right air filter for your home:

Understand MERV ratings

MERV stands for Minimum Efficiency Reporting Value and is a rating system that measures the effectiveness of air filters. The higher the MERV rating, the more particles the filter can capture. However, filters with higher MERV ratings can also restrict airflow, which can put a strain on your HVAC system. For most homes, a filter with a MERV rating between 7 and 13 is sufficient.

Consider your family's health needs

If you or someone in your family has allergies or respiratory issues, you may want to consider a filter with a higher MERV rating. HEPA filters, for example, can capture particles as small as 0.3 microns, making them a good choice for those with allergies or asthma.

Change your filter regularly

No matter what type of air filter you choose, it's important to change it regularly. A dirty filter can't effectively capture pollutants, and can even make your air quality worse. Check your filter every month and replace it as needed.

In addition to air filters, you may also want to consider an air purifier. Air purifiers can help to remove pollutants that air filters can't capture, such as smoke and odors.

Improving the indoor air quality in your home is an important step in protecting your family's health. If you're interested in an air purifier or need help selecting the right air filter, talk to your HVAC professional about your options.
