Air Purifiers by Office Size

The single most common purifier-buying mistake is picking a unit sized for a living room and expecting it to cover an open-plan floor. Match capacity to floor area, not price point.

Sizing guide

Space Recommended CADR

Single office / meeting room (up to 20m²) 120–180 CADR

Small open-plan (20–50m²) 250–350 CADR, or multiple units

Large open-plan (50–150m²) Multiple units or HVAC-integrated filtration

Full-floor / multi-room (150m²+) HVAC-integrated system recommended

For larger footprints, our HVAC-integrated EPR 5000 covers 465m²+ from a single duct-mounted unit, distributing both filtration and continuous surface sanitisation through existing ductwork rather than requiring multiple standalone purifiers.
