Are You Using the Right Air Filter for Your Home?

Air filters are essential to your heating and cooling system. They slow the buildup of dirt on coils and heat exchanges, which will cause a system to work that much harder. Choosing the best air filters for your HVAC system is an important step in keeping both your unit and family healthy.

Most HVAC technicians will recommend changing your air filter at least once every three months to maintain cleaner air and a more efficient system.

Know Dimensions, Style, and Material

You should know the size of the air filter needed for your system. Write down the dimensions, including the thickness and MERV rating recommendation (see information below), before purchasing exactly what you need.

If a material and style aren’t recommended by the manufacturer, research the different types of filters and decide which might be best for your situation. Having pets, frequently open windows, or smokers in your home can influence which type of air filter is right for you.

Check MERV Ratings

MERV stands for minimum efficiency reporting value, which lets the consumer know how small the particulates are that the filter will allow through it. A higher rating means that the filter will block smaller pieces of airborne debris.

It can seem counter intuitive, but a higher MERV rating is not what may be best for your system. A higher rating means that the pores in an air filter are smaller, which can put a strain on some systems, causing them to wear down over time. Make sure you follow your system’s recommendations for MERV ratings when purchasing filters.

Keep Your Family Healthier

Clean air filters are very important when it comes to the health of your family. They trap all sorts of things like pollen, pet dander, dust, smoke, mold spores, bacteria, and other airborne contaminates that can cause serious health issues. Using the highest MERV rating acceptable for your system will provide your home with the cleanest air possible.
