* MERV 9-12: These filters have high efficiency and are suitable for capturing very small particles such as viruses and other fine particulate matter.
CADR (Clean Air Delivery Rate)
Another important metric for evaluating air filter performance is the Clean Air Delivery Rate, or CADR. This measures the volume of clean air that an air filter can deliver per minute. The CADR rating is essential for determining the capacity of an air filter to clean the air in a particular space.
Importance of CADR Rating
The CADR rating is crucial for ensuring that the air filter can effectively clean the air in a given space. A higher CADR rating indicates that the air filter can deliver more clean air, which is essential for maintaining a healthy indoor environment.
Example of CADR Calculation
To calculate the CADR rating, you can use the following formula:
CADR (cfm) = Filter face velocity (ft/min) × Filter area (ft²)
Where:
– Filter face velocity (ft/min) is the speed at which air passes through the filter.
– Filter area (ft²) is the surface area of the filter.
For instance, if a particular air filter has a face velocity of 500 ft/min and an area of 4 ft², its CADR rating would be:
CADR (cfm) = 500 ft/min × 4 ft² = 2000 cfm
Particle Capture Efficiency (PCE)
Another crucial metric for evaluating air filter performance is the particle capture efficiency, or PCE. This measures the percentage of particles that a filter can capture. A higher PCE rating indicates that the air filter can capture more particles, which is essential for maintaining a clean and healthy indoor environment.
Importance of PCE Rating
The PCE rating is critical for ensuring that the air filter can effectively capture pollutants, allergens, and airborne pathogens. A higher PCE rating indicates that the air filter can reduce the concentration of airborne contaminants, which is essential for promoting better respiratory health and overall well-being.
Example of PCE Calculation
To calculate the PCE rating, you can use the following formula:
PCE (%) = (Number of particles captured / Total number of particles) × 100
Where:
– Number of particles captured is the number of particles captured by the air filter.
– Total number of particles is the total number of particles present in the air.
For instance, if a particular air filter captures 5000 out of 10000 particles present in the air, its PCE rating would be:
PCE (%) = (5000 / 10000) × 100 = 50%
Absolute Efficiency (AE)
Another key metric for evaluating air filter performance is the absolute efficiency, or AE. This measures the percentage of particles that a filter can capture, regardless of their size. A higher AE rating indicates that the air filter can capture particles of various sizes, making it more effective at removing pollutants and allergens from the air.
Importance of AE Rating
The AE rating is essential for ensuring that the air filter can effectively capture a wide range of particles, including those that are too small for a MERV rating system to capture. A higher AE rating indicates that the air filter can improve indoor air quality by reducing the concentration of airborne contaminants.
Example of AE Calculation
To calculate the AE rating, you can use the following formula:
AE (%) = ((Particles captured < 0.3 microns) + (Particles captured 0.3-1 micron) + (Particles captured 1-2 microns) + (Particles captured 2-5 microns)) / Total number of particles) × 100 Where: - Particles captured < 0.3 microns is the number of particles smaller than 0.3 microns captured by the filter. - Particles captured 0.3-1 micron is the number of particles between 0.3 and 1 micron captured by the filter. - Particles captured 1-2 microns is the number of particles between 1 and 2 microns captured by the filter. - Particles captured 2-5 microns is the number of particles between 2 and 5 microns captured by the filter. For instance, if a particular air filter captures 5000 particles smaller than 0.3 microns, 2000 particles between 0.3-1 micron, 1000 particles between 1-2 microns, and 1000 particles between 2-5 microns out of a total of 10000 particles, its AE rating would be: AE (%) = ((5000 / 10000) + (2000 / 10000) + (1000 / 10000) + (1000 / 10000)) × 100 = 50%
