How It Works

Slate’s filtration is specifically designed for Los Angeles water systems, avoiding costly and unnecessary filters

Sediment Pre-Filter

  • Catches dirt, sand, rust, and other larger particles

  • Protects the downstream filtration equipment

  • Helps prevent sediment from entering the home's plumbing

Whole-Home Carbon Filter

  • Reduces chlorine and chloramine

  • Improves taste and odor

  • Reduces certain organic compounds and other common water-treatment contaminants

  • Gives the water a cleaner feel and smell throughout the house

Water Softener

  • Removes hardness minerals, primarily calcium and magnesium

  • Helps prevent scale buildup in pipes, fixtures, water heaters, and appliances

  • Reduces spotting on fixtures

  • Creates that noticeably "softer" shower-water feel
