Why Your Life Ionizer Needs an Exterior Pre-Filter

Your Life Ionizer's internal filter does an excellent job removing contaminants - but it was never designed to handle heavy sediment loads, rust, or excessive chlorine common in Hawaii's water systems.

The Problem Without Pre-Filtration:
🔴 Internal filters clog 2-3x faster with heavy sediment
🔴 Replacement costs add up quickly ($80-120 every 3-4 months)
🔴 Reduced water flow and ionization performance
🔴 Potential damage to ionization plates from hard particles
🔴 Shortened system lifespan due to constant stress

The Solution: Exterior Pre-Filters
✅ Remove 95% of sediment BEFORE it reaches your main filter
✅ Extend internal filter life from 6-12 months to 12-18+ months
✅ Save $200-400 annually on filter replacements
✅ Maintain optimal water flow and ionization performance
✅ Protect expensive ionization plates from damage

For Hawaii Homes: If you have catchment water, well water, or notice rust/sediment in your tap water, an exterior pre-filter isn't optional - it's essential.

See What Your Pre-Filter Catches

This is what your exterior pre-filter removes BEFORE it reaches your expensive internal filter. Every grain of sand, rust particle, and contaminant caught here is one less thing clogging your main system.

What Pre-Filters Capture:
🟤 Sediment - Sand, silt, dirt, clay particles
🟠 Rust - Iron oxide from corroded pipes
🟡 Organic Matter - Leaves, algae, bacteria (catchment systems)
⚫ Carbon Fines - Particulates from municipal treatment
🔴 Scale - Calcium and mineral deposits
🟣 Agricultural Runoff - Fertilizer residue, pesticides

Hawaii-Specific Contaminants:

  • Volcanic ash and minerals (VOG periods)
  • Red dirt and clay from erosion
  • Organic debris from tropical environment
  • Salt spray corrosion particles (coastal areas)

The average Hawaii catchment system pre-filter captures 2-5 pounds of sediment per year. That's 2-5 pounds that would have destroyed your internal filter in months!

Why Replace Your Filter Regularly

Your Life Ionizer does an amazing job of balancing pH and removing impurities—but only if your filters are performing at their best. Over time, filters get saturated with chlorine, sediment, heavy metals, and other contaminants. Replacing them ensures:
