Two major brands are PUR and Brita. These water filters remove things that are harmful to your health, things that can increase the chance of getting cancer, and things that taste or smell bad.

The physics of filters is based on sieving, ion exchanges and other processes. Unlike a sieve or screen, a filter can remove particles much smaller than the holes through which the water passes.

Examples

  • Media filter
  • Screen filter
  • Disk filter
  • Slow sand filter bed
  • Rapid sand filter
  • Cloth filter
