Harnessing the power of pure oxygen, O2 Active Air Dispenser by TimeMist delivers continuous, consistent ambient fragrance. It provides a low VOC option and is an excellent alternative to more traditional technologies. Dispenser even works well in humid or arid conditions. Two-sided oxygen generator takes ambient air from one side and transforms it to pure oxygen on the other side. Resulting oxygen is channeled into the refill where it consistently squeezes pure fragrance oil out onto its unique cellular diffuser. High-quality fragrance is then carried throughout the room by natural airflow for a full 60 days. Refill provides odor-neutralizing agents that eliminate malodors and leave a fresh scent in the air. Vented sides allow effective fragrance dispersal. Recyclable refills are CARB and IFRA complaint and have no added VOCs or solvents. Visual light indicators provide refill and battery replacement reminders. Dispenser runs on 2 AA batteries (sold separately) and includes a keylock.
