This pitcher combines Brita's reliable filtering with a very convenient narrow shape and flip-top lid for easy refills. To operate, simply flip the lid and fill the water reservoir, then wait a couple of minutes for it to filter through. The filter used with this system has been certified by NSF International, a testing authority for water filtration products, and reduces copper and eliminates 99% of lead in tap water. Using activated carbon as well as an ion exchange resin, it also reduces chlorine, bad tastes, odors, and sediment--making it a lot easier to drinkthe recommended eight glasses of water a day. It comes with one filter, lasting approximately two months, and the pitcher is clear with a white top. --Maria Dolan
