When it comes to air filtration, MERV stands for Minimum Efficiency Reporting Value. This rating system is used to measure the effectiveness of air filters in removing pollutants from the air. The higher the MERV rating, the more efficient the filter is at trapping particles. A MERV 11 filter is one of the most effective filters available for residential use.
It can trap particles as small as 0.3 microns, including pollen, dust, lint, mold, dust mites, smoke, pet dander, and smog. It also eliminates most mold spores, car emissions, pet dander, and some larger bacteria and smoke particles. A MERV 11 filter is a must-have for households with children or pets. It filters out many of the most common air pollutants and irritants that can cause respiratory problems.
It offers more filtration than a MERV 8 filter, but not as much as a MERV 13 (the highest option suggested for residential use). The cost of a MERV 11 filter is a few dollars more than a MERV 8 filter, but it's worth it for the improved indoor air quality it provides. It's especially beneficial for people with mild allergies or asthma. If you're looking for an air filter that can remove smoke from your home, a MERV 11 filter is your best bet.
It's tested to remove particles as small as 0.3 microns and can help improve your indoor air quality.
