If something's in solution, then the ions are all dissolved in the solution. Therefore, they would pass through the porous texture of the filter. The residue is usually filterable, because it's mostly clumps of molecules.
Long story short: The ions are too small to be filtered. They just pass through the paper.

There is a method of filtration that separates out salts dissolved in a solution. It is called reverse osmotic pressure. It is used on sail boats sailing across the oceans to get fresh water as an alternative to the solar distillation of seawater but requires battery or solar power.
Generally speaking the salt ions dissolved in water are smaller than the water molecules in water. A normal filter, if it could filter out molecules would more likely filter out water molecules. But no normal filter can do even that.

if its all liquid then the filter can't do anything. if there are some solids then you can filter to help separate
