You’ll also have to change these filters more frequently than filters with a lower MERV rating. It is high efficiency furnace (92%) that had a MERV 8 1 inch pleated filter installed just outside the blower cabinet in the return duct. MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units. The higher the efficiency, the more effective it will be. V. vweosdriver. MERV 11. This rating, which ranges from 1-20, represents how well filter can catch smaller airborne particles ("1" meaning it can only catch large airborne particles, "20" meaning it can catch very small airborne particles.) A MERV 11 would be considered an “allergy” filter that does a good job of removing particles in all size ranges. MERV ratings classify filters on a scale on 1 to 20, and the higher the rating, the more particles the filter is able to capture. Be aware that as the MERV rating increases, the filter gets more restrictive and it will take more pressure and energy to push air through. Efficiency.

High-efficiency and high-MERV (Minimum Efficiency Reporting Value) rating filters seem beneficial because they filter out very small particulates, such as pollen, dander, and other allergens. Because high-MERV filters can trap more particles, they are likely to clog faster than low-MERV filters. The more sensitive a person is to allergens, the greater the need for a high-efficiency filtration system. This is the first time in the seven years it's been in operation that I've been having problems. An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. It also helps if you tell us what size. Choosing the right furnace filter is like the story of Goldilocks and the Three Bears. In addition, you may not get the air velocity required to reach all parts of your home leaving inconsistencies in temperature. The scaling of MERV is not linear; the difference between a MERV 6 and a MERV 8 is nearly double in the percentage of particles captured. MERV is a good way to help judge the effectiveness of an air filter. Is MERV 13 too restrictive? This means more energy is used, which will increase your utility bill. Filters with high MERV ratings may remove more harmful contaminates from your home, but they may actually reduce the quality of the air you breath if you select a filter with a MERV rating that’s too high for your HVAC system.

MERV 11 to 13 are high-efficiency filters that come in a variety of configurations. You need to find the rating that is not too high, not too low, but just right. Filters with higher MERV ratings trap small particles more effectively than filters with lower MERV ratings. This chart also shows that as the efficiency of the media increases, the resistance also increases. Merv 11 in 1" will remove the same particulate as a Merv 11 in 2" the difference is that the 1" will plug up faster then a 2" and be more restrictive. Other Rating Systems. A MERV rating between eight and 11 is adequate for most homes. Or in English, “how effective is your air filter?” MERV ratings range from 1-16. Choosing filters with deeper pleats (e.g., four-inch pleats) will increase the surface area of the filter and potentially reduce the pressure drop while increasing or maintaining a high MERV rating. So the low-MERV filter is hitting the ACCA design pressure drop. Filters with a MERV 11 rating have a dust spot efficiency of 60-65% and are 30 times more efficient than regular fiberglass filters. Low-efficiency filters typically lie within MERV 1-4 and high-efficiency filters are MERV 13 and beyond. MERV is a good way to help judge the effectiveness of an air filter.
