The Aqua Air™ 5 Function Shower Head produces a bigger and softer water droplet to enhance and improve your showering sensation and 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 and 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.
