The V-Air Flow is a cutting-edge, non-aerosol aircare solution, providing consistent, long-lasting fragrance for 30 days. With a dispenser made from 100% post-consumer recycled plastic that leverages innovative fan and Venturi Effect technology, it creates an even fragrance distribution throughout a space. The system intelligently adjusts based on room temperature, increasing fragrance output when temperatures drop below 59F/15C and conserving energy by turning off when the room is dark. The dispenser requires 2 cell batteries that are not included with the product.
