The EZ-Twist is "simply" an adjustable odor neutralizer for small areas where quick, safe and long lasting deodorization is desired. Designed for spaces up to 2,000 cu. ft. (60 cubic meters), the EZ-Twist dispenses a natural, deodorizing dry vapour through the use of unique, replaceable element technology. This unit requires no electricity or batteries. By rotating the cover, output can be precisely adjusted to meet user needs or to prolong product life.
