The Luft Duo is the world's smallest molecule purifier. This pack comes with two of these little purifiers in Christmas-themed colors, so you can keep one at home and one in your car, or gift the second one to someone you love. This purifier system utilizes UV LED technology to kill germs and bacteria on-site, plus titanium oxide/zinc for further purification. It zaps and eliminates dust, pollen, mold, and more, right down to the smallest particles they're made out of.

These purifiers are easy to clean and all you have to do to maintain them is rinse out and wash the metal mesh filter every two weeks. To power it up, plug it into the wall through a USB type-C cable. This tiny device is powerful, too. It's automatically energy-efficient and costs less than $2 to run in your home every day.
