The Sharp High Density Plasmacluster Ion Generator for Cars effectively reduces germs, bacteria, viruses, odors, mold, and fungus in your car. Cars can absorb odors such as sweat, cigarette smoke, and food and pet odor over time. The IG-DC2EB uses patented Plasmacluster Ion Technology with special high density output, in which it disperses positively and negatively charged ions throughout the car to safely break down microorganisms and odors (even those trapped in car seats and floor mats!). It is designed to fit perfectly into a cup-holder. Simple one-touch operation allows you to choose from 2 fan speeds. The unit only consumes 1.3 Watts on low, and 2.3 Watts on high. The unit also has LibraryQuiet operation (as quiet as 28 decibels, or the sound of rustling leaves). It lasts 19,000 hours without a decrease in performance. Car adapter included.
