Usage
1. Being exposed to direct airflow for an extended period of time could be hazardous to your health.
Do not expose occupants, pets, or plants to direct airflow for extended periods of time.

Cleaning and maintenance
1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling
