An enterprise advocates the concept of green environmental protection in production, and purchases a sewage filtration system to filter and treat sewage. It is known that the relationship between the remaining pollutants in the sewage $N$ (in $mg/L$) and time $t$ (in hours) during the filtration process is $N={N}_{0}{e}^{-kt}$, where ${N}_{0}$ is the initial amount of pollutants, and $k$ is a constant. If in a certain filtration process, 30% of the pollutants were filtered out in the first 2 hours, calculate the total percentage of pollutants that can be filtered out in the first 6 hours.
