EASY TO INSTALL - Rinse all filter parts with water; insert the filter into the straw; tighten the lid and secure the filter; install the silicone mouthpiece, and you're ready to enjoy clean water. Your home's tap water may appear clean, but harmful contaminants can enter the water supply and accumulate through old pipes.
