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.
