Both in the car and when travelling, the AELUS purifies the air quietly and efficiently using a HEPA H13 filter and photocatalysis with UV-A and UV-C LEDs. For use in the car, it has a stand with which it can easily be affixed to the headrest bars using Velcro strips. Thanks to its compact design and minimal weight, it is no danger to passengers in the case of an accident. A single button controls operation, while changing the filter requires the removal of a magnetic cap and the undoing of an Allen screw.
