156dBA at max speed.
2The 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 over 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.
3Tested by 3rd party SGS, refer to GB 21551.3-2010 but tested against Staphylococcus albus, Staphylococcus aureus and Escherichia coli in a 30m³ chamber with machine speed 10 and airflow projection at 50° The actual result may vary in practice.
4Tested by 3rd party SGS, refer to GB/T 18801-2022 but tested against H1N1 virus & human coronavirus (229E & OC43) in a 30m³ chamber with machine speed 10 and airflow projection at 50° The actual result may vary in practice.
5Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).
6Tested to JEM 1467 (acetic acid, acetaldehyde, ammonia), GB/T18801 (formaldehyde, benzene) and DTM-003282 (NO2). Gas capture rates vary.
7Third 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.
8Filter life is determined by dividing total dust load capacity by annual dust load. Annual dust load was calculated using GB/T 18801 daily mass formula. Results may vary in practice.
