Changing your air filter is essential in keeping the air in your home clean. It also helps protect your HVAC equipment from clogged coils and motors that can lead to costly repairs. Choosing the right air filter can be overwhelming. There are so many options!

MERV Rating

The MERV rating is a crucial indicator of air filter’s effectiveness in removing particles and contaminants from your HVAC system’s airflow. The grading scale ranges from one to 20, where higher ratings indicate superior filtration. It is strongly recommended that households with members suffering from allergies, respiratory problems, or other health conditions requiring cleaner indoor air opt for higher-rated filters. However, it must be noted that these filters are often thicker and can restrict airflow, leading to higher energy costs and causing your HVAC system to work harder. For the best balance of MERV and cost, look for a MERV 8 filter. This type of filter is 25% thicker for improved filtration, and it’s pleated to ensure energy efficiency and optimum airflow. It’s an ideal upgrade from standard fiberglass and poly fiber panel filters. This filter can catch small particles like mold spores, hair spray, and dust mites while preventing larger particles such as lint, sanding debris, and spray paint from entering your HVAC equipment.

Dust Capacity

Choosing the right size air filter is not just about reducing allergens and improving home health; it’s also a way to extend the life of your HVAC equipment. A dirty, clogged filter can strain the system, leading to damage and premature equipment failure. A poor-quality filter can leak dust into the unit and contaminate the coils and blowers, leading to damage and costly repairs. High-quality filters are made to a consistent thickness on predetermined centers, promoting even dirt collection and increasing filter longevity. Other filters include carbon and adhesive, which trap odor-causing gases and reduce bacteria and fumes for a fresher, cleaner indoor environment. Regardless of which type is best for your needs, the bottom line is that it’s essential to change the air filter often enough to keep dirt and other contaminants out of the engine. This will improve fuel efficiency and protect your engine.


People with respiratory problems like allergies, asthma, and bronchitis need higher-quality air filters because they trap microscopic particulates that cause these issues. In addition, infants, young children, and elderly adults also need higher-quality filters. High-efficiency filters are more expensive than standard fiberglass filters, but they provide better air filtration and lower energy bills. Electrostatic and HEPA filters are highly recommended because they capture many harmful pollutants, including dust mite debris, mold spores, pollen grains, tobacco smoke, pet dander, bacteria, chemicals, and gaseous vapors. Changing out your filters at least every three months (and swapping them out more often in homes with allergy troubles, furry pets, and heavy dust) can reduce electric bills by up to 15% during peak usage. A dirty filter also clogs the coils of your HVAC unit, which can lead to broken motors and coils. Ace carries various sizes and MERV ratings to fit your home’s needs, and some even come with extra features like odor-blocking and easier-to-replace designs.


Air filters are costly, especially if you opt for one with a higher MERV rating and a bigger size. However, it’s worth the investment since higher-rated filters can significantly improve your home’s air quality and prevent breathing problems like allergies, asthma, and bronchitis. Whether you opt for a flat panel or pleated filter, finding the right size is essential. Buying one that is too large will restrict airflow, while the reverse will happen when you purchase a smaller size. You also need to inspect your filter regularly. Ensure it’s clean by checking for dirt on the surface and inner layers. Changing your filter every three months (for 1-inch filters) or once a year (12 months) if you live in a dusty environment or on congested roads that require frequent acceleration and deceleration. This way, you can ensure your engine gets the air it needs to run correctly.
