Extremely bright green laser at 532 nm wavelength
Output power of <5mW (Class IIIa Laser Product)
What does all of this mean?
How do you know if you can see it in the air?

It means the power of the emitted light is no more than 5 mw (typical laser pointer limit), and its green light is visible when aimed at a surface that returns some light. You can see it in air if the air contains some condensed vapor (like visible steam) or suspended dust particles. A foggy night really shows it off. Of course the usual precautions apply; don't aim it towards anyone's eyes directly or via a reflecting surface.
