A Merv 11 filter is an air filter designed to capture a wide range of pollutants and irritants, including pet dander, smoke, smog, and even air from coughs and sneezes. This type of filter is especially beneficial for households with children or pets, as well as those with allergy sufferers. The MERV rating system is a standard used to compare filters with different efficiency ratings. A MERV 11 filter has a higher efficiency rating than most other filters, meaning it can capture finer particles and remove more pollutants from the air.
For households with family members suffering from respiratory problems, a MERV 11 filter is recommended. It is also a good choice for homes with smokers or pets, as it can better eliminate odors. Filters with higher MERV ratings are more effective at trapping small particles than those with lower ratings. MERV 17 to MERV 20 filters are typically used in operating rooms, cleanrooms, and other settings that require absolute cleanliness.
