AlkaViva Athena H2 vs Tyent UCE-13 Plus
The AlkaViva Athena H2 and Tyent UCE-13 Plus sit at different price and install tiers — ~$2,200 countertop mid-range vs ~$4,195 under-counter flagship. The UCE-13 Plus delivers verified 1.8+ PPM hydrogen, 13 plates, and lifetime labor hidden under your sink. The Athena H2 offers UltraWater lab-tested filtration and 1.3 PPM on 7 plates for nearly $2,000 less — but with a 5-year labor cap and countertop-only flexibility. Buy the UCE-13 Plus if you own your kitchen and want Tyent's verified best concealed under the counter; buy the Athena H2 if budget and contaminant lab data matter more than flagship H₂.
