While your tap water may look clean, it can contain potentially harmful contaminants picked up on its journey through aging pipes. PUR pitcher filters with Maxion technology reduce these contaminants. Each PUR water filter is certified to remove 96 percent Mercury and 95 percent of certain industrial pollutants as well as reduce chlorine (taste and odor) and more. The pitcher has a slim, space-saving design that fits easily in the fridge while the comfort-grip handle and easy-fill lid make it easy to use.
