The Aqua Air™ 5 Function Shower Head produces a bigger & softer water droplet to enhance & improve your showering sensation & pleasure. It works by water flowing through the Aqua Air™ cartridge within the shower head handle draws in air which is then mixed with the water & creates bigger softer aerated water droplets within a volumised shower spray which enhances the showering sensation. Aqua Air™ shower heads come with an optional ECO water saving device which can save up to 50% of water when compared to similar standard shower handsets.
