Interior + Exterior = Maximum Protection
AutoShip isn't just for internal filters. You can include exterior pre-filters too – and they all count toward your 8-item minimum for 20% savings.
Why add pre-filters to your AutoShip?
Pre-filters sit between your water line and ionizer, catching sediment and chlorine before they ever reach your internal filters. The result:
✓ Internal filters last longer – Less work for Filter #1 and Filter #2
✓ Better water quality – Two-stage protection beats one
✓ Lower long-term costs – Even with pre-filter expense, total maintenance cost drops
✓ Protected ionizer – Cleaner water in = healthier plates and longer machine life
Smart AutoShip Combo:
That's 8 items exactly – qualifying you for the full 20% discount and 5-year price lock on everything.
