This kettle really does think of everything. It has a removable, washable filter to keep your water clean and free from debris; this sits inside the spout and can be easily taken out, rinsed under the tap and replaced. The 21271 sits on a 360 base so it can be comfortably used whether you are right or left handed and to keep your work top clutter free the base also has integrated cord storage so it can be stored away at your convenience. The dual water window means you can clearly see the level when filling up the jug from either side meaning overfilling is a thing of the past.
