Two ways to enjoy Pollenex’s special oxygen/water treatment. Water and oxygen visibly churn in showerhead to provide a faster, more powerful massaging spray. Set spray to “soft mist” for maximum spa experience or “full spray” for regular shower action. Clear design lets you see the water and the oxygen combine. Chrome. Works with any standard shower. Easy to install. 2 spray settings: soft mist & full spray. Rack not included. (home environment)
