Enagic (Kangen) K8 vs Enagic (Kangen) SD501

The Enagic K8 and Enagic SD501 are both Kangen MLM machines with single-stage filtration and unpublished H₂ data — but they target different buyers within the same ecosystem. The K8 is the current 8-plate flagship with a modern touchscreen at ~$4,980. The SD501 is the legendary 7-plate workhorse at ~$3,980 with a rare 5-year full warranty. Neither offers good tech-per-dollar versus direct-sales alternatives, but if you are committed to Kangen, the K8 wins on plates and interface; the SD501 wins on price and mechanical simplicity.

Enagic Wins Roughly $1,000 less at list ($3,980 vs $4,980), 5-year FULL parts & labor vs K8's 5-year limited warranty
