This unit is powered via a standard USB connection (5V), making it compatible with car charging adapters, laptops, power banks, and USB wall chargers.

As a general guideline, we recommend inspecting the filter every 3–6 months and replacing it when it appears visibly dirty or when airflow seems reduced.
