It was a moment that I was looking to acquire a filter jug to stop carrying packs of mineral water. The price in stores dissuaded me long until I came across this special decanter. The object is of good quality, strong and (this is important!) Very easy to maintain. One cartridge lasts a month (a small counter on the decanter prevents the time to change it) and issue unfiltered drinking water for daily use. Nothing to report at the taste, and the filtered water is actually less limestone (over white deposit). Refills of filter cartridges are at attractive prices on Amazon. I recommend.
