When it comes to air filtration, the MERV 11 filter is one of the most effective options. It can eliminate a wide range of pollutants, including pollen, dust, lint, mold, dust mites, smoke, pet dander, and smog. This makes it an ideal choice for pet owners and people with respiratory issues. MERV stands for Minimum Efficiency Reporting Value and is the primary rating system used for air filtration.
A MERV 11 filter is capable of trapping particles as small as 0.3-1 µm, which includes most mold spores, car emissions, pet dander, and some larger bacteria and smoke particles. In comparison to the MERV 8 filter, a MERV 11 offers more filtration for cleaner air. It also filters out many of the most common air pollutants and irritants that can cause respiratory problems. However, it doesn't filter as much as the MERV 13 (the highest option suggested for residential use).
The cost of a MERV 11 filter is slightly higher than other options, but it's worth it for the improved indoor air quality. 41% of the MERV 11 for my scrubbing filters is good, especially considering that air will pass through it several times while recirculating. MERV 5-MERV 8 filters are also good options and can remove most pollen, mold spores and dust mites. However, if you're looking for maximum protection from smoke particles and other pollutants, a MERV 11 filter is your best bet.
