Each lock, and its cautions
Filter types
Water Filter Types Compared: Carbon, RO, UV, Gravity and More
What each major filter technology actually removes, what it doesn't, what the NSF/ANSI certification numbers mean, and realistic cost-per-gallon and maintenance.
Contaminants
Tap Water Contaminants Explained: Chlorine, Lead, PFAS, Nitrates and More
An honest, contaminant-by-contaminant walk through what's commonly found in US tap water, what's actually regulated, and where the science is still catching up.
Your report
How to Read Your Water Quality Report (Consumer Confidence Report)
Where to find your CCR, how to actually read the table of numbers, what the report can't tell you, and what to do if you're on a private well.
RO and minerals
Reverse Osmosis Water and Minerals: What the Evidence Actually Says
RO does remove most dissolved minerals along with contaminants — here's what that means in practice, what remineralisation adds back, and when RO is the right call.
Practice and water
Water and Daily Practice: Hydration Around Pranayama and a Yoga Session
Sensible, unglamorous guidance on water timing around practice and pranayama, plus an honest look at the traditional morning water habit — framed as custom, not treatment.
Copper vessels
Copper Vessels and Filtered Water: What Copper Storage Does and Doesn't Do
Copper vessels store and gently release copper ions into water; they are not a filter. Here's what the evidence actually shows, official copper intake limits, and how to use a copper vessel sensibly if you choose to.
Breath practice sits alongside this material — see the breathing guides, and Yoga Nidra if you would rather rest than retain.
