The Meridian-N collection has been designed to take care of the environment. Its double- flush mechanism means, that only the water needed, is used. The WC cisterns also feature a limited 4.5/3-litre water capacity, unlike other cisterns that use up to 6 litres. It is, in short, the best way of saving money and taking care of water. MERIDIAN-N WCs, M2-N and ESMAI faucets are equipped with new generation water-saving mechanisms.
