Elemaris features 'Meter' which is a smart cartridge exchange indicator that measures water hardness, volume and time for optimum and personal BRITA performance. The Meter works by measuring the volume of water filled into the jug hopper and when the tap water comes into contact with the Meter prongs, it calculates the hardness of your water. Using both of these measurements along with your personal use, the Meter will calculate the lifetime of your filter cartridge and will advise to change it every month or sooner if your water hardness or use exhausts the cartridge sooner.A pour through lid for easy one-handed filling, soft grip handle and non-slip base. 1.4L filtered water capacity and 2.4L total capacity.
