Finer Filtration. People who live in areas with questionable water quality might need more than a faucet filter. According to its maker, the PurHome X-5 Whole-House Water Filter relies on a three-stage filtering process to remove chlorine, chloramines, VOCs, and heavy metals like lead and mercury from water. One unit can handle the filtration needs of a 2,500-square-foot home; more-powerful models are available for larger homes. The X-5 costs $800. PuriTeam, 888/491-4100, puriteam.com
