MERV 11 air filters are designed to trap 95% of air pollutants, including pet dander, lint, dust, pollen, debris, mold spores, smoke and smog. This type of filter is ideal for pet owners and those with mild allergies or asthma. It offers more filtration than Merv 8 filters, but not as much as Merv 13 (the highest suggested option for residential use).The MERV 11 discount filter is tested according to how efficiently it captures particles measuring between 3 and 10 microns. It is capable of removing more than 85 percent of particulate debris in this size range, as well as 64 to 79.9 percent of particles measuring between 1 and 3 microns.
This performance is based on the international industry standard minimum efficiency reporting value (MERV) rating. When used in conjunction with proper cleaning measures, households with furry companions can experience fewer allergy symptoms. Air Filters Delivered makes ordering your MERV 11 replacement filters easy and affordable. You can choose from standard, rare and custom sizes to find the package that best suits your needs. MERV 11 filters are designed to keep the air clean and protect the health of your family or co-workers. They block at least 65-79% of airborne particulates in the 1.0 to 3.0 micron size range.
Anything higher than a MERV 11 is designed for commercial households or households with family members suffering from respiratory problems. The higher the MERV rating, the more airborne pollutants the air filter can remove before entering your home. MERVs 14 to 20 are best for hospital and laboratory applications where as much air needs to be captured as possible. MERVs 4 to 6 are not recommended for residential use, but have adequate disposal efficiency in handling industrial applications. Using an oven filter with a higher MERV rating than your use case requires may have adverse effects. Established in 1987 by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE), MERV is the only standardized filter classification system. It is important for all homeowners to research the Merv rating system, what it entails and which rating would be right for their air filtration needs.
Changing your air filter regularly is one of the most important maintenance tasks you can perform to keep your HVAC system in perfect condition.
