HAVC system

HVAC system comprises primary filter, secondary filter and high efficiency particulate air. The filter is replaced at the different intervals. The primary filters and secondary filters are required to be replaced every 6 months or when the pressure is more than twice of the initial one, and HEPA is performed with leakage test every year.
