This type of water dispenser with filter has already bought a second one. The first one is for self use. It has been almost a year and there is no problem. The filtered water is not as cost-effective as tap water. It doesn't smell like electric kettle in tap water. It is also very convenient to add water. There is also a waste water storage tank underneath. It is humanized. I bought the same type of water to give away to relatives,Living with such a water dispenser is convenient and reassuring. Praise Qinyuan!!!
