Kangen Water in San Miguel de Allende

Tap water in San Miguel is not potable. Most households and expats default to one of four options: garrafón delivery (20-litre jugs), reverse osmosis from a local pickup point, a reverse osmosis system under the sink, or bottled water from supermarkets like City Market, Mercado Sano, or La Comer.

Each has real limitations. Garrafón is logistically annoying, supplied by large brands that take money away from the local economy, and quality varies by supplier—most local services don't publish their filtration or testing standards. Reverse osmosis removes contaminants effectively but also strips the minerals that make water beneficial—calcium, magnesium, bicarbonates—producing flat, slightly acidic water that isn't health-promoting. Bottled water quality varies, contains microplastics, creates significant plastic waste, and costs more per litre than either alternative.

A Kangen K8 ionizer addresses what none of these does: it filters the source water, then electrolyses it to produce hydrogen-rich, alkaline drinking water while preserving the beneficial minerals. It also produces six additional water types—for cooking, skin care, cleaning, and disinfecting—from the same unit.

San Miguel de Allende sits at approximately 1,900 metres above sea level. At altitude, the body loses water faster through increased respiration rate and perspiration—a mechanism the body uses to regulate temperature and oxygen exchange. Most people who move to SMA from sea level report that adequate daily hydration requires more conscious effort than they were used to.

Some research on hydrogen-rich water—the type produced by electrolytic ionizers like the K8—suggests it may support cellular hydration more efficiently than standard water due to the presence of dissolved molecular hydrogen (H₂). The clinical research is ongoing and not yet conclusive for altitude-specific applications, but the general hydration case at altitude is well established.

What we've noticed personally: since using the K8 in San Miguel, we drink more water, feel better at altitude, and have eliminated plastic bottle waste from the house entirely.

Most households in San Miguel use Microdyn or Bacdyn—an ionised silver solution—to disinfect produce before eating it. It kills bacteria and pathogens on the surface. It does not remove pesticides, wax coatings, or chemical residues. For that, most people use vinegar or hydrogen peroxide (agua oxigenada), neither of which is particularly effective.

The K8 produces two outputs that address both problems from the same unit:

SMA tap water is not potable and contains varying levels of minerals, sediment, and treatment chemicals depending on the neighbourhood and source. The K8's internal filter (replaced annually at ~$150) handles standard municipal treatment chemicals, chlorine, and sediment.

For source water with high TDS (total dissolved solids), heavy metals, or PFAS contamination, a pre-filter before the K8 is recommended. We assess your specific water source as part of the consultation—what the water report shows determines whether the K8 alone is sufficient or whether a pre-filter makes sense.

If you've had your SMA water tested, bring the report to the consultation and we'll go through it with you. If you haven't, we'll assess your source water as part of the session—the neighbourhood and water source in SMA matters more than a generic city-level report.
