The ONA Mist Dispenser is a great way to control odors in small rooms and areas where the odor source is constant or repeated. Rooms such as bathrooms, entry or exit areas, pantries, workshops, and garbage collection areas that are approximately 6,000 cubic feet (170 sq. meters) are aptly serviced with an ONA Mist Dispenser under normal airflow conditions. Larger areas are best controlled with one of our larger CFM dispensers such as the ONA Breeze or ONA Odorstop. The ONA Mist Dispenser has an electronic eye that senses bright light or low light. You can set it to only spray in the dark (low light) or during the day (or when lights are normally on). The third option allows you to set it to spray 24 hours per day. The spray is metered out in three adjustable time intervals 7.5 minutes, 15 minutes, or 30 minutes.
