1. An oil mist separator for an internal combustion engine that separates an oil component in a gas, which is introduced from a crankcase of the internal combustion engine, from the gas, the oil mist separator comprising: a porous filter that separates, from the gas, the oil component in the gas, the porous filter being provided in a passage, through which the gas passes,wherein the porous filter is coated with a counteragent for neutralizing an acid substance;a plurality of gas passages that are separate from each other, each of the plurality of gas passages is provided with the porous filter that is coated with the counteragent;a switching device that selects one of the plurality of gas passages through which the gas is allowed to pass;a controller that estimates a degree of decrease in an amount of the counteragent, based on information concerning the degree of decrease, and that, when the degree of decrease exceeds a predetermined degree, controls the switching device so as to change the gas passage through which the gas is allowed to pass. 2. The oil mist separator according to claim 1, further comprising a binder provided on a surface of the porous filter, wherein the counteragent is dispersed and held in the binder. 3. The oil mist separator according to claim 1, wherein the information concerning the degree of decrease includes a mileage of a vehicle on which the internal combustion engine is mounted. 4. The oil mist separator according to claim 1, wherein the porous filters provided in the plurality of gas passages are different in fineness of pores from each other. 5. The oil mist separator according to claim 4, further comprising a controller that changes the gas passage, through which the gas is allowed to pass, with the use of the switching device according to a flow rate of the gas, wherein the controller controls the switching device so that the higher the flow rate is, the finer pores the porous filter has that is provided in the gas passage selected by the switching device. 6. The oil mist separator according to claim 1, wherein the counteragent is calcium carbonate. 7. The oil mist separator according to claim 1, wherein the porous filter is made of foam metal or foam resin. 8. The oil mist separator according to claim 1, wherein the porous filter is provided so that the degree of decrease in the counteragent coated can be seen from an outside.
