For water that’s contaminated with large particles like pebbles, insects, plant matter, or dirt, you can strain out the contaminants. Line a fine-mesh strainer with muslin, cheesecloth, a clean dish towel, or even a clean cotton shirt. Place the strainer over a bowl, and pour the water through the strainer to remove the particles. Note that straining the water like this will only remove large particulates, not pathogens, heavy metals or other contaminants.
Strain the water.
