Now you can flavor your filtered water. You install a flavor cartridge (peach, raspberry or strawberry) in your new PUR pitcher or new PUR faucet-mount (you need to buy a new one to accommodate the flavor cartridge, and you still need filter cartridges, too). When you want flavor in your water, you push the button while pouring or running the tap. A flavor cartridge (two for $9.99) flavors about 75 drinks.
