  • 1 In maximum setting. Tested for air projection, purification coverage in an 81m³ room and heating performance in a 35m³ room.
  • 2 Third party full machine testing based on GB/T 18801-2018 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
  • 3 Tested for filtration efficiency at 0.1 microns (EN1822). Gaseous capture rates vary.
  • 4 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%.
  • 5 In maximum setting. Tested for air projection, purification coverage in a 81m³ room.
  • 6 We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes at maximum fan speed, the airborne concentration in the chamber was reduced by 99%. Real-life efficacy may vary.
  • 7 After reaching target temperature and maintaining it. Tested in a 35 m³ chamber when using the hot air mode and the product setting temperature is 25 °C. Comparing with continuous operation with power consumption of 2050W. Real life results may vary depending on room insulation.
  • 8 Compared to earlier generation. Tested in a 35m³ room (DTM961).
