This is a water-purifying showerhead from Eaimiu. It has a maximum water-saving effect of 80%. The chlorine removal filter provides water that is gentle on the skin and hair. It features water pressure and flow rate adjustment, as well as an on/off one-touch switch to stop the water flow at hand. It has approximately 304 0.3mm spray holes, realizing an ultra-fine water flow. I have used it only once and have stored it completely dry. Includes the product box and instruction manual. Thank you!
