When it comes to air filtration, the MERV rating system is used to measure the effectiveness of a filter. The higher the MERV rating, the more efficient the filter is at capturing particles. 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 those 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. MERV 9 filters can trap less than 50% of particles in this size range, while MERV 10 can stop up to 64%, MERV 11 up to 79%, and MERV 12 up to 89%.MERV 11 filters are more efficient than MERV 8 filters because they can capture smaller particles. This means they offer additional protection against pet dander, dust mites, self-emissions, and dust that damages the lungs.
It's also our most popular type of air filter.The MERV 11 will increase indoor air quality by removing 85% of micron-sized air pollutants, maintaining the efficiency of the HVAC unit. However, please note that a MERV rating higher than 13 may adversely affect some HVAC systems, so it's important 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. Anything higher than a MERV 11 is designed for commercial or domestic homes with family members suffering from respiratory problems.
