Air Filtration & Indoor Air Quality

Filtration is the recurring-spend consumable layer of airport HVAC and the front line against desert dust. This sub-category covers AHU bag and panel filters, fresh-air-intake pre-filters engineered for high dust loading, HEPA filtration (up to H14) for sensitive and high-occupancy spaces, and molecular/activated-carbon filters that strip jet-fuel vapours, ozone and odours drawn in from the apron. It also covers IAQ monitoring — CO₂, PM2.5, VOC and humidity sensing that ties back into the BMS. Buyers weigh filter efficiency (ISO 16890 / EN 1822) against pressure drop, because every extra Pa of resistance is fan energy paid for all year; desert-optimised filters trade higher dust-holding capacity for longer change intervals and lower lifecycle cost.
