A Merv 11 filter is an essential choice for those who have children or pets, as it can trap a wide range of air pollutants and irritants. This type of filter is capable of eliminating mold spores, car emissions, pet dander, smoke particles, and some larger bacteria. According to ASHRAE, a MERV 8 filter is not the best option for residential HVAC systems. Higher MERV ratings such as MERV 13 and 14 are recommended for optimal air filtration.
The MERV rating of an oven filter indicates its minimum capacity to filter air pollutants. It is important to select a filter with the highest possible MERV rating for your specific HVAC system in order to ensure the best air quality. Allergy sufferers should definitely consider investing in a MERV 11 filter to ensure their air is free from smoke, smog, pet dander, and other common air pollutants.
