Inline air filter apparatuses, systems and methods

Abstract

Systems and methods compensate for static pressure created by a very high-efficiency air filter in a heating, ventilation and/or air conditioning (HVAC) system by disposing a very high-efficiency air filter in a return to a HVAC system air handling unit (AHU), disposing a variable speed air impeller in the return to the HVAC AHU, and calibrating a speed of the variable speed air impeller to overcome static pressure between the very high-efficiency air filter and the HVAC system AHU created by the very high-efficiency air filter. (An) air pressure sensor(s) may detect the static pressure and/or otherwise provide data to a digital control unit for the digital control unit to calculate the static pressure between the very high-efficiency air filter and the outlet opening, to calibrate the speed of the variable speed air impeller to overcome static pressure between the very high-efficiency air filter and the HVAC system AHU.
