Both. But filtration is more common.
Distillation.
Because distillation produces vapour and impuritites can not leave with the vapour
Solar distillation is a process in which water is evaporated using solar energy and then condensed to produce freshwater. It involves using a solar still to collect and purify water by separating it from salts, pollutants, and other contaminants. Solar distillation is a simple and sustainable method for obtaining clean drinking water in areas where access to freshwater is limited.
Desalination is the process of removing salt and other impurities from seawater to make it suitable for drinking or irrigation. This can be done through methods like reverse osmosis or distillation. These processes involve separating the salt from the water to produce fresh water for consumption.
The process of removing fresh water from salt water is called desalination. It can be achieved through methods like distillation or reverse osmosis. These methods involve separating the salt from the water to produce fresh drinking water.
Salty water may undergo distillation process to become freshwater.

Water is needed for distillation to control the amount of alcohol and to produce steam. Much of the water is boiled off during the process but the remaining percentage dictates the proof.
It is becaise filtration only seperates the large particles (particles larger then the filter paper). Germs, virus and fine impurities will pass through the filter paper as they are much smaller then the holes in the filter paper. Ditillation produces pure water as the water is changed from the liquid state to the gaseous state (only water is boiled and nothing else) before it is condesed to turn it back into the liquid state.
This process is called Desalination.
Like most distilled beverages, distillation increases the alcohol content.
Fractional distillation of coal is a process in which coal is heated to produce a range of hydrocarbon products, such as gases, liquids, and solids. These products can be further refined and used as fuels or chemical feedstocks. The process takes advantage of the different boiling points of the components in coal to separate them based on their molecular weight and properties.
