Reduce harmful chemicals as well as unpleasant odors and flavors in your tap water with this faucet-mounted vertical filter from Pur. It attaches to most standard faucet heads, filtering out contaminants including cryptosporidium, giardia, lead, mercury, asbestos, turbidity, sediment, and leus by up to 98 percent. Certified by the National Sanitation Foundation (NSF), the filter also eradicates the odor and flavor of chlorine and reduces discoloration. Filtered tap water also tastes better and costs less than bottled water. Made from carbon and a special active agent that removes lead, the Pur Plus faucet filter fits onto the faucet head so water flows directly through the filter into the sink. Instructions for attaching the filter are available on the Pur website, including a video. Users can opt to tilt the filter back to allow unfiltered water through for tasks like dishwashing. Water flows through the filtration system at a rate of 2-1/2 liters per minute with pressure levels of 60 PSI. This system includes Purs ASM filter life indicator, which notifies users when its time to change filters. Filters should be changed every 150 gallons and can be purchased in bulk. While Pur filters rid water of many harmful chemicals, coloration, and bad flavors, they do not soften water or remove fluoride. This item weighs one pound. --Jessica Reuling
