The Pure Water Protocol — Filtration, Contaminants, and Longevity
PFAS ("forever chemicals") were detected in 45% of US tap water samples in the largest federal study to date.
Which contaminants matter, which NSF/ANSI certifications actually filter them, and the filtration tier matrix — pitcher through reverse osmosis.

2-3 liters of water passes through your body every day, for the rest of your life. Whatever is dissolved in it has 365 days a year of cumulative exposure to your kidneys, gut, and cardiovascular system. Most of the biomarkers you optimize with diet, supplements, and training can be undermined by chronic exposure to PFAS, lead, chlorine byproducts, and microplastics in unfiltered tap water. This guide covers what's actually in US drinking water, which filtration technologies remove which contaminants, and the NSF/ANSI certifications that matter.
What's inside
- Why water purity is the foundational layer — the chronic-exposure math, why this confounds every other biomarker
- The contaminant landscape — PFAS, microplastics, lead, chlorine/chloramine, heavy metals, pharmaceuticals, pesticides, fluoride
- Health endpoints affected — the biomarkers that change with chronic contaminant exposure (apoB, TSH, hs-CRP, eGFR)
- Filtration technologies compared — reverse osmosis, activated carbon, ion exchange, distillation, UV
- NSF/ANSI certifications that matter — 42, 53, 58, 401, P473 explained
- The operational answer — under-sink RO vs countertop RO, what to look for
- Remineralization — why RO water needs minerals back, three solutions
- Daily intake protocol — 2.5-3.5L per day, timing, electrolyte support
- Testing your own water — EWG database (free), mail-in lab testing, after-filter verification
- Integration with the longevity stack — how water purity pairs with the rest of the Vault
Who this is for
Adults running a longevity protocol who want their biomarker work to actually move. People who've optimized diet, supplementation, and training but haven't audited the water layer. Anyone whose municipal water utility is on the EWG's elevated-PFAS list (about 200 million Americans).
Brand integrity
PureLongevity is faceless. No founder personality. Every contaminant claim cites the EPA, EWG, ATSDR, or peer-reviewed source. Every filtration recommendation references NSF/ANSI certification standards specifically — not vague "third-party tested" claims.
Included in The Longevity Vault
The Longevity Vault includes this plus 13 other research-grade protocols for $97 (vs $346 retail). Covers biomarkers, NAD+, mediterranean nutrition, sleep, gut, fasting, hormesis, red light therapy, strength, VO2 max, cortisol, social connection, alcohol substitution.

What's inside. Every Purelongevity formula is built around clinically-dosed actives drawn from peer-reviewed human trials. We use bioavailable forms (NMN — not niacinamide; magnesium glycinate — not oxide; trans-resveratrol — not the cis isomer) at the doses the literature actually supports. No proprietary blends. No fillers. Every active is listed by name and milligram on the Supplement Facts panel.
What we don't use. Artificial colors. Artificial flavors. Hydrogenated oils. Titanium dioxide. Magnesium stearate. Carrageenan. Soy. Gluten. Dairy. GMOs.
Care & storage. Keep the bottle sealed, cool, and dry — pantry shelf is perfect. Avoid direct sunlight and humidity (so the bathroom counter is not). Once opened, use within 90 days for peak potency. Expiration date is printed on the bottom of the bottle.
For devices (Red Light Therapy): wipe the LED panel monthly with a dry microfiber cloth. Never use solvents, alcohol, or wet cloths on the LEDs. Store upright in a dry environment between 50–85°F.
Independently verified. Every batch leaves the facility with a Certificate of Analysis (COA) — available on request — confirming identity, potency, and absence of heavy metals (lead, arsenic, cadmium, mercury), microbial contamination, and residual solvents.
