There is a very succinct explanation by Michael Osterholm [1][2] where he says that the virus is spread both by droplets & aerosols, and that sharing the same air with another person is the primary vector (that isn't intended to sound as alarmist as it probably does).
From what I understand the best prevention is to reduce face-to-face contact with other people where possible, but an N95 mask would definitely help prevent contraction in public spaces.
Of course, these measures seem extreme since ~80% of people will barely notice they are infected / have mild symptoms, but it's all about peak-load reduction.
