Antimicrobial Countertops WHO: Microban International and countertop maker Cosentino USA
WHY: Until now, antimicrobial agents that fend off bacteria and mold have been limited to cleaning supplies and products made of plastic.
HOW IT WORKS: Cosentino's Silestone is made by compressing natural crystal quartz at the molecular level. In the process, the microbe-resistant agent is bonded to the rock so the countertop has a germ-fighting property when cut, shaped or even chipped.
APPLICATIONS: Antimicrobial countertops make sense because food is prepared on them. Still, makers warn, they're no substitute for cleaning.
HOW MUCH: In April 2005, Home Depot will begin selling Silestone with antimicrobial protection for $40 to $95 per square foot.
