Most heating and air conditioning systems include a particulate air filter for the
primary purpose of protecting the equipment from fouling by airborne particle and
providing some minimum level of IAQ.
Bioclimatic provides air cleaning and air purification solutions based on many types of technologies. In almost all cases these solutions utilize at least one stage of particulate air filtration Filter BasicsFilters are usually composed of fibrous materials to remove solid particulates (also known as particulate matter or PM) such as dust, pollen, mold, and bacteria from the air. These filters are made in many sizes, with different materials, and for differing filtration efficiencies as required to capture particles of different sizes. Available media can be specified to perform better for damp, “sticky”, or other environments, and with fire rating classifications. Common materials used in particulate air filters are paper, fiberglass, foam, or wire mesh. ASHRAE defines the particle removal efficiencies using MERV ratings from 1 to 16 (ASHRAE Systems and Equipment Handbook 2016) that establish an industry-recognized basis for filter specification. HEPAs (high efficiency particulate arrestance) are for more stringent requirements ranging from 99.97% to 99.99% removal of 0.3 (µm) particle size or larger (with even more efficient filters available for very special requirements).
Benefits•Increased comfort•Better IAQ for improved health, reduced absenteeism, better productivity•Protection of downstream components for improved performance, such as coils and higher efficiency filters•Maintenance of HVAC system efficiency and longevity•Lower operating and maintenance costs•Compliance with codes, regulations, and standards
