When it comes to air filtration, the MERV rating system is a standard way to measure the efficiency of a filter. A Merv 11 filter has a higher efficiency rating, meaning it can capture finer particles and remove more pollutants from the air. But is a MERV 11 filter the right choice for your needs? The MERV 11 filter will improve indoor air quality by removing 85% of micron-sized air pollutants, while also preserving the efficiency of your HVAC unit. Although they may cost a few dollars more than a standard filter, the extra efficiency is generally worth the investment.
Comparing filters with different MERV ratings is made easier by the standard rating system. Anything higher than a MERV 11 is usually used in commercial or domestic homes with family members who suffer from respiratory problems. Filters with higher MERV ratings are better at trapping small particles than those with lower ratings. Filter King offers a convenient MERV 11 air filter subscription service, so you never have to worry about forgetting to replace your filters.
In terms of filtration, a MERV 8 is considered superior to filters with lower ratings. This is especially true for homes with smokers or pets, as MERV 11 filters are better at eliminating odors. MERV 17 to MERV 20 filters are typically used in operating rooms, cleanrooms, and other settings that require absolute cleanliness. A MERV 11 filter blocks at least 65% to 79% of particles in the 1.0 to 3.0 micron size range.
It is an ideal choice for pet owners and people living with certain health conditions, such as mild allergies and mild asthma. However, it's important to note that a MERV rating higher than 13 may negatively affect some HVAC systems, so make sure your unit can support a higher rating before purchasing.
