But we’re not done yet. That clear-ish water still has microscopic particles and odors. Enter filtration. The water trickles through layers of sand, gravel, and activated carbon—yes, the same stuff in your Brita filter, but on steroids. This carbon is like a sponge for bad tastes and smells.
Think of it as sending your water through a mile-long, super-tight colander. Everything that’s left is basically invisible, but we’re not trusting our taste buds just yet. A good filtration system can capture particles as small as one micron, which is one-thousandth of a millimeter.
