More² clean air, less noise, less energy

Our unique filtration technology that we call HEPASilent™ sets us apart. The combination of electrostatic and mechanical filtration allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance — resulting in quieter and more energy efficient air purifiers.

¹ Refers to the removal of 99% of airborne dust particles (0.5-3 µm) in 33 min on highest fan speed based on AHAM AC-1 protocol; not applicable to larger particle sizes and particles that have already settled on surfaces. "Dust" defined as airborne dust.

² HEPASilent™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration (at the same rpm on the fan and energy consumption of 18,3W). Based on internal testing on particle CADR according to GB/T18801-2015 standard.
