HEPAirX Ventilating Air Cleaner - Installation, Operation and Maintenance Guide

HEPAirX® units are portable, window mounted, room air conditioning units with an integrated air-to-air energy recovery ventilator and a high efficiency particulate air (HEPA) filter. The units are intended to reduce the amount of airborne particulates that may affect people’s health, especially those who suffer from upper respiratory distress. They are designed to control the temperature in the room while ventilating the room with approximately one to two air changes per hour of fresh (outside) air. This fresh air is mixed with the room air being re-circulated through the HEPA filter at the rate of nine to twelve times per hour. The exact number of air changes depends on several factors but the principal factors are room size and filter loading. Most important is that all of the fresh outside air and room return air go through the HEPA filter before being supplied to the room. (Refer to Illustration A-1-1 for identification of major components and parts).
