- 5-stage filtration on upper models
- 7" touchscreen on Echo Ultimate
POINTS OF CAUTION
- Parent company (Synergy Science) filed Chapter 11 ~2023 — future support uncertain
- No lifetime warranty — 5 or 10 years only, and prorated (loses 25%/yr after year 1)
- Echo One uses reverse osmosis — which strips beneficial minerals from water
- H₂ infusion technology, not traditional electrolysis — a fundamentally different product
- Post-bankruptcy ownership and service capacity unclear
