Are You Using the Best Air Filter for Your House?

Air filters are essential parts of your heating and cooling system. They slow down the buildup of grime on coils and heat exchanges, which can cause a system to work harder. Choosing the best air filters for your home’s system is a key step in keeping both your unit and family healthy.

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

Know Dimensions, Style and Material

It is critical that you know the size of the air filter needed for your HVAC system. Write down its dimensions, including the thickness and MERV rating recommendation (see below), before leaving for the store so you know that you are purchasing exactly what you need.

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

Check MERV Ratings

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

A higher MERV rating isn’t always what will be best for your system. A higher rating means that the pores in the air filter are smaller, which puts a strain on some systems, causing them to wear down over time. Always review and follow your system’s recommendations for MERV ratings when purchasing air filters.

Keep Your Family Healthier

Clean air filters are important when it comes to the health of your family. They trap pollen, mold spores, bacteria, pet dander, dust, smoke, and other airborne contaminates that can cause many health issues. Utilizing the highest MERV rating acceptable for your system will give your home the cleanest air possible.
