The compact EZ-Twist odor neutralizer is ideal for contents restoration, as well for treating odors in areas up to 2,000 cubic feet. It does not require electricity and can be adjusted with a simple twist. As air flows over the replaceable fiber disc, a non-toxic vapor is released to help counteract a wide variety of common malodor problems. The Ez-Twist is sold in packages of 12, with replacement discs also available by the dozen.
