Statistically speaking, the toothbrush is the most unsanitary thing in your bathroom, trumped only by your toenail clippers and the rubber ducky you use to stop up the bathtub. Cleanse germ-covered teeth cleaners with today’s Groupon: for $20, you get $40 worth of UV toothbrush-sanitizing products from Violight.

Violight’s sleek sinkside sanitizers slay 99.9% of toothbrush bacteria—including salmonella and E. coli—with a barrage of germicidal UV light. Winner of a 2005 Industrial Design Excellence Award, the Philippe Starck–designed original sanitizer ensconces a family of four brushes in a glowing ovoid container ($49.95) where they can live side-by-side without sharing germs or arguing over whose turn it is to do dishes. Groupon holders can also get the cartoony ZapiPOP ($29.95), whose ninja and smiley-face incarnations toddled across the pages of the NY Daily News and Self magazine’s 2009 holiday gift guide. Or snag a portable iZap travel sanitizer ($19.95), which cleanses a single brush in a long, thin container that fits easily into a suitcase, next to your plane tickets and Pig Latin phrasebook.
