MERV 8 vs MERV 11 Filter What’s The Difference Between.jpg


People may not distinguish between the functions of MERV 8 and MERV 11 filters since they both work nearly the same. However, they have some differences regarding their MERV rating level, air flow capabilities, and filter moves. Each air filter has some advantages and disadvantages. MERV 8 and MERV 11 filters can be used for residential purposes, but you must choose yours according to your system’s requirements.

Why Do Some People Think MERV 8 Is A Good Option?

MERV 8 filters are well-round that provide above-average air filtration support for your home. They are commonly used, so you might think they are priced more than the affordable rate. However, this is not a correct idea because they are high priced because of their high demand. Those with good ideas about the filter market know MERV filters are the highest-rated products that many residential air filter suppliers sell. MERV 8 gives a good performance rate at a reasonable cost. MERV 8 filters trap and block particles like dust mites, mold, pollen, and larger dust particles. 

If you compare MERV 8 with other filters with a lower MERV rating, you will see why MERV 8 is superior in air filtration. MERV 8 filters are undoubtedly less priced than their efficiency. They give us better output than many less efficient products, making them more demanded. However, you should go for a higher MERV rating if you have family members with breathing difficulties and asthmatic issues. The higher the MERV rating is, the more the filter can prevent outdoor pollution and save pets or family members with respiratory issues. 

Do You Need MERV 11 Filters?

MERV 11 has a higher rating than MERV 8, which means MERV 11 filters can capture the maximum number of particles and clear them out of the air more efficiently. They trap dust mites, mold, pet dander, particles, smog, smoke, etc. MERV 11 filters are expensive compared to a standard filter. 

Now the question may arise do you need this high MERV rating? A Higher MERV rating is suitable for capturing more particles and filtering more, but you need to remember that if the rating is too high, it has too much thickness. Of course, you shouldn’t consider buying a filter with too much MERV rating as the thickness of the filter material can lead to restricting the airflow. 

You might ask again what issues will occur due to the restricted airflow? Restricted airflow due to the filter material’s thickness can decrease the comfort level, increase energy bills, and increase the wear and tear of HVAC components. A higher MERV rating air filter can even damage the compressor, air conditioner coil, and heat exchanger.Above all, MERV 11 filters are too high to use for residential purposes. You can use MERV 14 or higher for commercial HVAC systems that can handle the thickness of the filter material. 

Significant Differences Between MERV 8 & MERV 11

Both MERV 8 and MERV 11 filters have some pros and cons. Based on their different criteria and working function, you have to decide which one to choose for your system. As we already know, higher MERV rating filters can capture microscopic particles. So, MERV 11 filters effectively trap 95% of airborne particles, whereas MERV 8 filters can trap 90%.Superior standard MERV 11 filters require more frequent cleaning than basic standard MERV 8 filters. Since MERV 8 filters are recommended for residential use, they are more affordable than MERV 11 filters. Compared to fiberglass air filters, MERV 11 filters perform better than MERV 8 filters. 


The above discussion gives you an idea about the differences between MERV 8 and MERV 11 filters. We recommend using Custom Filters Direct to buy custom size MERV 8 and MERV 11 HVAC and furnace filters online. You can see the MERV rating printed on the filter. The MERV rating indicates the type of air you can get from the filter. The differences allow you to quickly determine the type of filter you need for your house.
