Three components, in sequence.
Purify, remineralize, structure. The sequence matters — UMH Pure must be the last stage so structuring isn't undone by downstream filtration. Tap a step for the spec.
Five stages. 0.0001 micron membrane.
Sediment pre-filter, two carbon stages for chlorine and VOCs, the reverse osmosis membrane (the workhorse), and a polishing post-filter. 97.5%+ TDS reduction. Removes what carbon can't catch — dissolved metals, fluoride, PFAS, pharmaceutical residue.

Pays back in year 5. Then it just keeps saving.
Cumulative 10-year cost for a 4-person household at current MSRP. The Hydration Stack jumps to $2,499 at install, then runs nearly flat — small steps for filter replacements every 12–24 months. Every other option keeps climbing.

Filter cycles are gallons-driven, not calendar-driven.
Most brands publish a single replacement interval. We publish ours by household size — because a 2-person home runs through a 2,500-gallon cycle on a different schedule than a 5-person home.

UMH Pure
Zero consumables. The UMH Pure structuring stage has no replacement filters and never requires service for the life of the system. Subscribe & Save applies to the MM8500 + Sango cartridge replacements only — auto-shipped to match your tier, skip or pause anytime.
Five points of contact under the sink. One sequence.
UMH Pure must be the last stage — running structured water back through filtration would partially undo the molecular geometry. Every install we do verifies this order on site.

Frequently asked.
What's actually in the Hydration Stack?
Three components in sequence under the kitchen sink. MicroMax 8500 — 5-stage RO certified to NSF/ANSI 42, 53, 58, 401, 372. Sango Coral cartridge — 70+ trace minerals at 2:1 Ca:Mg ratio. UMH Pure — passive vortex structuring, TÜV EU certified. $2,499 system price.
What's the difference between filtered and purified water?
Filtration uses carbon to catch particles down to ~1 micron — sediment, some chlorine, some lead. Purification (reverse osmosis) uses a 0.0001-micron membrane — 50,000× finer. At that scale RO removes dissolved metals, PFAS, fluoride, pharmaceuticals, and 97.5%+ of total dissolved solids. Brita is filtration. The Hydration Stack is purification + remineralization + structuring. Read more in our Clean Drinking Water guide.
Does this remove fluoride?
Yes — over 95% per NSF/ANSI 58. Pitcher filters and basic carbon systems can't.
How does this compare to a daily electrolyte packet?
LMNT, Liquid IV, Cure are formulated for acute use — heavy sweating, sickness, hard runs. They're high-sodium, high-dose. The Sango Coral cartridge delivers 70+ trace minerals at parts-per-million — the steady-state range your body uses for daily homeostasis. Keep your packets for the saunas. Replace the daily ones.
What does the structuring stage actually do?
UMH Pure runs water through a passive vortex — the same flow pattern in mountain springs. Result: water organized into negatively-charged molecular clusters, often called EZ (exclusion zone) water. Research suggests this structure may be absorbed more efficiently through aquaporin channels. Mechanism well-documented in peer-reviewed literature; large-scale human RCTs underway. Hand-built in Austria, TÜV EU certified, zero electricity, zero consumables. More on the optimization protocol.
Why is Sango Coral better than alkaline drops?
Synthetic alkalizers raise pH using sodium bicarbonate or potassium hydroxide — pH up, no minerals delivered. Sango Coral raises pH naturally through mineral content alone, releases ionic minerals at the 8-micron particle size your cells absorb directly, and has been part of the Okinawan diet for generations. See the full Sango Coral spec.
How often do filters get replaced?
Household-dependent. 2–3 people: ~24 months. 3–4 people: ~18 months. 5+ people: ~12 months. The MM8500 has a 2,500-gallon design capacity — gallons through the system drives the cycle, not a calendar. UMH Pure has zero consumables and is never replaced.
I rent. Can I install this?
Yes. Choose the dual-function kitchen + RO faucet at checkout (+$197) — uses your existing faucet hole, no countertop drilling. Lives entirely under the sink, removes in ~20 minutes when you move. Active concierge customers in our SoCal and Houston full-service zones get a free reverse-install at lease end.
How long does install take and what does it cost?
Most installs run 60–90 minutes for any licensed plumber. In SoCal and Houston, our team handles it directly — quoted on a free consultation. Everywhere else, your plumber gets a free 15-minute video call with ours, plus 24/7 concierge access. We don't bundle install into the system price because plumber rates differ by market.
What's the warranty?
10 years on the MM8500 tank. 5 years on UMH Pure. 60-day water-quality guarantee — full refund if water quality isn't measurably improved against the day-one lab test. 30-day fit guarantee — full refund if it doesn't physically fit your home. Lifetime concierge support is standard.
Has it been independently tested?
Yes. The MM8500 is certified by WQA to NSF/ANSI 42, 53, 58, 401, and 372. UMH Pure is certified by TÜV EU. Manufactured by Puronics (Franklin Water Treatment, Livermore CA), a WQA Gold Seal manufacturer. Sango Coral is sourced from a food-grade Japanese supplier and lab-tested for purity batch-by-batch.
Why $2,499? It's a lot.
Math: a 4-person household drinking bottled water spends ~$1,800/year — the Hydration Stack pays back in year 5 vs Brita+LMNT and year 1.4 vs bottled water. After year 5, every glass costs ~$0.04. The unit price reflects the full system — RO membrane, certified housing, Sango cartridge, UMH structuring device, dedicated faucet — sized for 10+ years of service, not 60 days like a pitcher.
