AlkaViva Delphi H2 vs Tyent UCE-13 Plus
The AlkaViva Delphi H2 and Tyent UCE-13 Plus are the two serious under-counter flagships in the ionizer market — both hide the engine under your sink and leave only a designer faucet on the counter. The UCE-13 Plus is Tyent's verified 13-plate flagship with independently tested 1.8+ PPM hydrogen and forever labor coverage. The Delphi H2 is AlkaViva's Vesta H2 in concealed form: UltraWater lab data and ~1.4 PPM H₂ at roughly $1,200 less. Buy the UCE-13 Plus if verified hydrogen ceiling and 13-plate headroom justify the premium; buy the Delphi H2 if contaminant lab reports and budget matter more than verified 1.8+ PPM.
Expert Review Verdict
- → Roughly $1,198 less at list ($2,997 vs $4,195)
- → UltraWater filtration lab-tested against 249+ contaminants
- → Same 9-plate Vesta H2 engine in a proven under-counter form factor
- → 75-day trial matches Tyent — lower entry for hidden-install buyers
- → Lifetime parts with 10-year labor — strong AlkaViva under-counter value
- → 13 vs 9 plates — flagship electrolysis surface area in the same under-counter class
- → 1.8+ PPM H₂ independently verified vs ~1.4 PPM brand-published on Delphi H2
- → True Forever lifetime parts & labor — Delphi caps labor at 10 years
- → Stronger verified ORP (−1,050 mV vs up to −800 mV)
- → Dual .01µ UltraFilter with third-party lab documentation on hydrogen output

✓ Buy the AlkaViva Delphi H2 if...
- → Your budget ceiling is under $3,000 — UCE-13 Plus is ~$4,195 plus install
- → UltraWater independent contaminant testing is your primary decision driver
- → ~1.4 PPM at drinkable pH is sufficient — you don't need verified 1.8+ PPM
- → You want proven AlkaViva under-counter engineering at the lowest flagship UC price
- → 10-year labor coverage is acceptable for a permanent kitchen install
🏆 Buy the Tyent UCE-13 Plus if...
- → You want the highest verified H₂ in an under-counter machine — Delphi tops at ~1.4 PPM published
- → 13 plates matter for hard water, high flow, or full alkaline/acidic range use
- → Forever lifetime labor beats Delphi's 10-year labor cap on a ~$4,200 investment
- → You want Tyent's third-party lab documentation, not brand-published H₂ only
- → You're comparing under-counter flagships on performance — not just filtration lab sheets
