With the Philips HD9318  you can easily boil enough water for 7 cups of tea. That makes this kettle very suitable for families and handy if you're having people over. Thanks to the handy cup indicator, you'll know exactly how much water to boil for a cup of tea. That way, you'll boil just the right amount of water and save energy. Simply open the lid or fill up the kettle via the spout. The indicator light shows you if the kettle is turned on or off. The scale filter holds back lime particles and is easy to rinse under the faucet. If the water is boiled, the kettle switches off automatically.
