*Required fields

  • 1 The ability of purifying a large room up to 100m2 (10m*10m) proven from a Computational Fluid Dynamics (CFD) modelling, with the purifier placed in a corner of the room running at the maximum flow and horizontal projection reaching 10 metres to fully mix the room. The projection distance was measured from internal flow reach testing under the maximum directional airflow. The actual performance in real life condition may vary.
  • 2 Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
  • 3 Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
  • 5 Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
