This is the antibac2K. It’s a compact, lightweight air cleaning system that looks like a spherical alien ship. When you plug it in and switch it on, the blue and green LED lights illuminate and the thing starts spinning, disseminating a proprietary air filtration mist into the atmosphere. The effect is similar to those bulky ionic filters they sell at Sharper Image—it gets rid of bad odors, eliminates allergy-inducing dust particles, and kills of 99.99% of bacteria such as salmonella…but this one’s much smaller and cooler-looking.
