Distilling water is the absolute best way to purify it. The water is heated to make steam and as it condenses it is drained off and you end up with purifyed water while the impurities remain in the original container. You can build your own solar powered still and purify water to make it safe to drink. Water distillers are expensive to buy one that is even sort of fast at distilling so this diy project would save money in the long run especially since it works off the sun. Off Grid News shares the tutorial on building this solar powered still.
