When it comes to air filters, the MERV rating is an important factor to consider. The higher the MERV rating, the more efficient the filter is at capturing particles in the air. A MERV 8 filter is able to capture between 50% and 65% of the smallest particles, while a MERV 11 filter can capture between 65% and 79%. This may not seem like a huge difference, but it can make a big impact on air quality.
MERV 11 filters are ideal for pet owners and people with mild allergies or asthma. They offer more filtration than MERV 8 filters, but not as much as MERV 13 (the highest option suggested for residential use). This range of MERV values can trap particles in the 1.0-3.0 micron range, which includes pet dander, dust that damages the lungs, and self-emissions. In this range, MERV 9 filters can trap less than 50% of particles with a size of 1.0-3.0 microns, while MERV 10 filters can stop up to 64%, MERV 11 filters can get up to 79%, and MERV 12 filters are capable of trapping up to 89%.
This means that MERV 11 filters are more efficient than MERV 8 filters because they can capture smaller particles. They offer additional protection against pet dander, dust mites, self-emissions, and dust that damages the lungs. This makes them a great option for homes with pets or those looking for even better air quality than what the MERV 8 can provide. It's also our most popular type of air filter. Please note that a MERV rating higher than 13 may adversely affect some HVAC systems, so it's a good idea to verify that your unit can support a higher MERV rating before purchasing.
Filter King offers a hassle-free MERV 11 air filter subscription service, so you never forget to replace your air filters. MERV 11 air filters block at least 65% to 79% of particles in the air in the 1.0 to 3.0 micron size range. This rating is more efficient than MERV 8 and 11 with the ability to filter even more allergens from the air. Anything higher than a MERV 11 is designed for commercial or domestic homes with family members suffering from respiratory problems. The MERV 11 will increase indoor air quality by removing 85% of micron-sized air pollutants, maintaining the efficiency of the HVAC unit. It's an excellent choice for pet owners and those looking for improved air quality in their home.
