Which Air Filters Have the Highest MERV Ratings?

Your air conditioning system is likely one of the biggest investments you’ll make for your home, so it’s only logical to assume that you want to get the most out of it, right? Getting the most bang for buck starts with the air filter you choose for your air conditioning system. Without the right air filter, your AC will never reach its full potential in terms of efficiency and overall cooling power. But how do you know which filter is right for you? The MERV rating is a good place to start.

What Is a MERV Rating?

MERV is the acronym for Minimum Efficiency Reporting Value. Put simply, the MERV rating determines how efficient an air filter is. MERV ratings range from 1 to 20, where the higher the number, the less particles that can pass through. Typically, MERV ratings are grouped by particle size and characteristics.

When it comes to air filters with the highest ratings, they are typically suited for large space, including:

Rating 9 – 12: These are best suited in large residential homes, some commercial spaces and hospitals labs. These filters are powerful enough to ward off humidifier dust, legionella, flour and vehicle emission particulates.

Rating 13 – 16: These filters are best fit for hospitals and surgical centers as they fight against bacteria, smoke, paint and more.

Rating 17+: Filters with the highest ratings are used in manufacturing rooms for electronics and pharmaceuticals.

Is the MERV Rating Really Important?

Opting for an air filter with a good MERV rating is very important! Considering air filters help filter out things like pollen, dust mites, carpet fibers, mold spores, dust, dander, tobacco smoke and potentially dangerous bacteria, a quality air filter will help you keep your home and family healthy. It’s also important to understand MERV ratings so you can select the best air filter for your home or business. Not all homes and businesses are alike, so an air filter that works perfectly for your home might not be the best fit in your neighbors. When it comes to ratings, a higher rating isn’t always better either. An air filter with a high rating has smaller pores for the air to flow through, which can create more resistance in airflow than an air conditioning system can handle. As a result, the air conditioning system won’t be as efficient as it could be.
