  • It costs less per gallon.
  • Needs fewer filter changes.
  • And it doesn’t make your water taste weird.

  • Use Berkey filters with activated carbon to filter out at least 79% of contaminants in your drinking water. (Berkey Light and Travel Berkey are the only types available in California.)
    • This includes Arsenic, Haloacetic acids, PFOS, and PFOA.
    • Berkey filters can also remove up to 99.99% of any Lead in Yorba Linda water.
    • Brita can filter 20 contaminants and Lead depending on the filter.
    • Note: We may receive a commission if you decide to purchase filters through links on this page.
  • To filter out 32 of the 35 contaminants, consider a Reverse Osmosis water filtration system for your house.

*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
