When should I replace the filter in my Laserliner AirBreeze 120 air purifier?

[SanNaomi]

To ensure your Laserliner AirBreeze 120 air purifier continues to operate at peak performance, monitor the filter replacement indicator. The instruction manual specifies that the Filter reset button will flash when the filter requires changing. To replace the filter, first, power off and unplug the air purifier. Then, detach the filter cover by turning the tab on the underside counterclockwise. Remove the old HEPA13 filter and replace it with a new one, ensuring it's correctly placed within the device. Secure the new filter by reattaching the filter cover and turning the tab clockwise. Finally, reset the filter indicator by pressing and holding the Filter reset button for three seconds until all symbols illuminate and stop flashing. Regularly replacing the filter, as indicated by the device, helps maintain the air purifier's efficiency and ensures the best air quality.
