Alien ship masquerades as air filter

Just like in the movies, they attack when you least expect it. It had been months since we'd encountered any spherical alien vehicles, but they're back--disguised a harmless air filter.

The "Antibac2K" claims to be a lightweight air-cleaning device that eliminates 99.99 percent of bacteria and other contaminants. That's a whole 0.02 percentage points more than other air filters, and we germaphobes all know how important that difference is.

But benefits aside, this circular menace is betrayed by its LEDs, which we all know the classic alien calling cards. We hope only that it doesn't joins forces with the evil Sanrio empire.
