What is MERV

The Basics: What is MERV and How is it Measured?

What is MERV? MERV is one of the rating systems you might keep seeing when you research furnace filters. MERV stands for Minimum Efficiency Reporting Value, and it is a measurement of how effectively an air filter can remove airborne particles from the air. The MERV rating ranges from 1 to 20, with 1 being the lowest level of filtration and 20 being the highest.

The rating is determined by measuring the filter’s ability to trap particles of varying sizes such as pollen, mold spores, pet dander, and other common allergens. The higher the MERV rating, the more efficient the filter is at trapping these particles. That does not mean you can use any MERV rating in your HVAC system though! So what is MERV? In a sentence, the industry standard for filtration effectiveness of air filters.

Common Misconceptions About MERV Ratings

Now that you understand what is MERV rating on filters. It’s just as important to understand you might not need a higher MERV rated filter. Many people believe that the highest MERV-rated filter is always the best choice. However, this is not necessarily the case. Filters with high MERV ratings can actually damage your HVAC system if it is not designed to accommodate such a filter. This is one of several reasons we only offer up to a MERV 13. Additionally, high MERV-rated filters are not always appropriate for all settings, such as those with low air flow. It is important to choose the right filter for the job, rather than simply selecting the highest MERV rating available.

Different Types of Air Filters: Which is Best for You?

Now that we’ve answered- what is MERV? You might be wondering what MERV should i use? It’s important to note- there are several types of air filters available, each with its own strengths and weaknesses. Fiberglass filters are the most common type and are designed to capture larger particles, such as dust and lint. MERV rated pleated filters like Airspire uses are more efficient than fiberglass filters and are better at trapping smaller particles. We believe every home should use a MERV rated pleated filter. The only drawback is pleated MERV filters cost a lot more than fiberglass. Until now.

The Importance of Choosing the Right MERV Rating

What is MERV? The American Society of Heating, Refrigerating and Air Conditioning Engineers also known as ASHRAE along with EPA manage the MERV rating system. This is why choosing a MERV rated filter is one of the most important considerations when selecting an air filter. Choosing the right MERV rating will depend on your individual needs, such as the presence of pets, allergies, or respiratory issues. A filter with a MERV rating of 8-11 is typically suitable for most residential settings, while a MERV rating of 13 is suitable for newer homes or older homes with a HVAC system that can handle the restricted airflow from a MERV 13.

For those with severe allergies or respiratory issues, a higher MERV rating like 11 or 13 may be necessary. It is important to note that higher MERV ratings can reduce the airflow in your HVAC system, so it is important to make sure your filter is not only the right size, but also the right MERV.
