Frequently Asked Questions - LR 12 STEBA

How to clean the filter of the device?

Unplug the device and turn it upside down. Loosen and remove the filter. Vacuum the surface of the filter with a vacuum cleaner, without vacuuming the interior to avoid damaging the HEPA filter. The filter is not washable.

When should the filter be replaced?

When the screen displays 'Filter Replace', it is time to replace the filter. You can order a replacement filter from Steba customer service under reference 93.12.00.

What do the colors of the light ring mean?

The light ring indicates air quality measured in PM2.5: green for optimal air (0-50 µg/m³), yellow for moderate air (51-150 µg/m³), red for poor air (from 151 µg/m³).

How to activate night mode?

Press the night mode button (9). All previous settings are retained, but the power goes to minimum and the lighting turns off.

What to do if the airflow is low?

Check that the filter is not obstructed or dirty: clean or replace it. Also ensure that the air inlet is not blocked by obstacles.

Can I use the device with a power strip?
