No, it is not possible to completely switch off all LEDs. In silent or night mode, the digital display light is dimmed to minimise disturbance, and with the light sensor the control panel is automatically switched off or dimmed in dark environments; touching the power button for 3 seconds manually switches all lights off, but they are switched on again by touching any button.

No, unfortunately not.

What is the exact model designation?

The air purifier uses a 3-layer filter system (pre-filter, HEPA NanoProtect, activated carbon) to filter 99.97 % of particles from a size of 0.003 micrometres, which also includes very small particles such as fine dust, allergens and viruses. Whether it effectively filters the nanoparticles (e.g. UFP, ultrafine dust) produced during 3D printing in particular depends on their size - most are in the range of 0.01 to 0.1 micrometres and are therefore captured very well. For complete assurance, it is advisable to check the exact particle size of your 3D printer, but in principle the filter performance for typical 3D printing particles is very high.

According to our information, the following is included in the scope of delivery: air purifier, filter and operating instructions.
