The diameter specification of 0 3 microns responds to the worst case. Portable air cleaners also known as air purifiers may be particularly helpful when additional ventilation with outdoor air is not possible without compromising indoor comfort temperature or humidity or when outdoor air pollution is high. Clogged coils can t heat or cool the air passing over them and they may damage the system.
Each of these filter dryers has two desiccant towers one that absorbs moisture particles and oil in the air while the other reactivates saturated desiccant so you have an uninterrupted supply of clean dry compressed air.
A diesel particulate filter or dpf is an exhaust aftertreatment device that traps particulate matter such as soot and ash. As air moves through a building s hvac system air filters trap and collect large and small particles such as dust allergens and microorganisms. It traps air born particles that get sucked in with the air and keeps them from blocking the blower and clogging up the coils. The most penetrating particle size mpps.
