A buttoned-up winter home is a warm one, no doubt. The downside to all of that draft-dodging is the stale, stuffy, and (let's face it) germ-filled air that comes with it. When you can't open a window for the cold, there's another way to get a breath of fresh air. Try the small, unobtrusive GermGuardian pluggable air sanitizer. The device removes smoke, cooking fumes, and other scents from the air to help you breathe easier, while a built-in UV-C light is designed to zap germs without the use of toxic chemicals. Now, if it only did the dishes! Available on Amazon; $37.13.
