Surgical masks will do the same thing, and for much cheaper.
A US-Chinese team of researchers created a simulated examination room with mechanized mannequins spaced 6 feet apart to represent coughing and breathing humans. They found that flu viruses floated between the two and were "inhaled" by the breathing mannequin, but that an N95 respirator sealed to the mannequin's face stopped 99.8% of them.
A poorly fitted respirator or a loose-fitting surgical mask, by contrast, blocked only about two thirds of the virus particles.
You are correct, in that it only protects against breathing. Eyes and other mucus membranes spots needs to be covered as well in-case of coughing.
2) Go to Wuhan and sell them at 1000% the cost
3) Get rich
4) ???
5) Dies

Assuming the virus infects through the pulmonary system, this is the way to go for protection. Of course, if the virus can enter through the eyes (as another poster said above), that's another story.... (which is a rarer occurrence as the binding molecules required would be different)

Healthcare professionals in Wuhan, etc., were using N95 masks, and caught 2019-nCoV anyway. They switched to Tyvek bunny suits with full face shields. If N95s make you feel better, whatever floats your boat.
[for anyone looking to scam people and profit off people's fear, well, FU.]
FDA certifies only the "healthcare" version of N95s:

One "certified" model:

NOT the usually lower-cost industrial versions sold at Home Depot, Lowe's, etc. Is there a functional difference? No, but the ones "certified" can be priced much higher.
Another scientific opinion, which supports my contention:

The study reported 'no significant difference in the effectiveness' of medical masks vs. N95 respirators for prevention of influenza or other viral respiratory illness.

Just don't eat any roasted bats and stay hunkered down indefinitely and maybe we will persevere.

Won't get rich unless you have billions of masks because Chinese government doesn't allow sellers to increase the price.
