Measuring How an Air Purifying Device Works
Dust, pollen, mold, and mildew are just a few of the airborne pollutants that can negatively affect your family’s health. Indoor air pollution can cause health problems ranging from dry skin and sinus issues to breathing problems, chronic headaches, and much worse depending on the types of pollutants in the air.
The good news is that your Seattle HVAC Contractor can install air purifying devices to provide your home with clean, healthy air. When measuring how well air cleaning devices work, your HVAC contractor will look at the following factors:
Minimum Efficiency Reporting Value
The efficiency of particle removal air filters is measured by the minimum efficiency reporting value (MERV) for air filters installed in the ductwork of HVAC systems. The American Society for Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) developed this measurement method to allow for comparison of air filters made by different companies. Your HVAC service provider can help you select the most efficient filtering solution based on the size of your home and the size and capacity of your heating and cooling system.
Clean Air Delivery Rate
Air cleaning devices are usually evaluated by their effectiveness in reducing airborne pollutants, which is measured by the clean air delivery rate (CADR). The CADR is a measure of an air cleaner’s delivery of contaminant-free air, expressed in cubic feet per minute. For example, if an air cleaner has a CADR of 200, it means particle levels will be reduced to the same concentration as would be achieved by adding 200 cubic feet of clean air each minute. Your Seattle HVAC contractor can help you select the right air cleaning device based on the size of your home and current air pollution levels.
