Health Effects of Fluoride

  • Skeletal fluorosis at levels above 4 mg/L (bone pain, joint stiffness)
  • Dental fluorosis in children at levels above 2 mg/L
  • At 0.7 mg/L (water fluoridation level), helps prevent tooth decay
  • Possible thyroid effects at high chronic exposure

Health risk severity: Moderate. Governed by the National Primary Drinking Water Regulations.

How Fluoride Gets Into Drinking Water

  • Intentional water fluoridation (0.7 mg/L target, beneficial)
  • Natural deposits in certain rock formations
  • Industrial discharge (aluminum, fertilizer production)
  • Naturally elevated in some groundwater (especially arid regions)

What to Do About Fluoride in Clearwater Water

  1. Reverse osmosis removes 90%+ of fluoride
  2. Activated alumina filters are effective for fluoride
  3. Bone char carbon can reduce fluoride
  4. Standard activated carbon filters do NOT remove fluoride

Look for filters certified under NSF 58 for fluoride removal.
