Quamist is a dual-mode water-saving attachment for taps/faucets. Quamist water saver can be attached to your existing tap within a minute. The water saver reduces the water output by 95% by converting the normal flow to fine mist. You can change from mist mode (0.6 LPM) to shower mode (2.5-3 LPM) by twisting the cap. Shower mode saves more than 85% water from your faucet.
