Specialty — Acid Neutralizing

ACID NEUTRALIZING
FILTERS

Acidic water (pH below 7) corrodes copper pipes, leaves blue-green stains on fixtures, damages water heaters, and leaches lead and copper into your drinking water. Neutralize it.

Acid Neutralizer
Calcite Acid Neutralizing Whole House Filter
Raises pH of acidic well water using natural calcite media. Self-correcting — as water pH rises, calcite dissolves more slowly. No chemicals, no electricity.

Understanding Acidic Well Water

Acidic water — typically with a pH below 6.5 — is common in areas with granitic geology, high rainfall, or shallow aquifers. It is corrosive by nature, and that corrosivity attacks your plumbing system continuously. Copper pipes develop pinhole leaks. Blue-green staining on sinks indicates copper dissolving into your water. Lead and copper levels rise as fixtures corrode.

A calcite neutralizer raises pH passively without chemicals by dissolving calcium carbonate into the water as it passes through. The result is softer, less corrosive water that protects your plumbing and improves water quality throughout your home.
