My regular kitchen tap reads about 130 parts per million. The spigot settles between eight and nine parts per million. I show both readings on two meters in my new 48-minute ESTC presentation, Pure Water From Your Kitchen Sink. I distilled water for years before switching, because of the electricity, the slow output and the cleaning. As I say in the talk, “I’m not distilling any water and I’m not spending a single penny on electricity.”
I start by comparing filtered water with pure water. Ordinary filtering takes out some of the chlorine and chemicals but leaves the heavy minerals behind. That is why I also show the inside of a kettle I have used for many years.

Kitchen sink readings on two meters
My regular tap water is already filtered. On the TDS meter it reads about 130 parts per million. Then I let the spigot flush while the meter reading falls past 29 and 15 PPM. Those are intermediate readings. The final reading settles between eight and nine parts per million. On a conductivity meter, the tap reads 0.25 millisiemens per centimeter and the spigot comes down to 0.01. “Well, that’s the instant proof right in front of your eyes.”
What the 48-minute presentation covers
- Filtered versus pure: why filtered water still has the heavy minerals in it.
- The kettle: a tea kettle I have used for maybe 20 years. “And the inside looks brand new, right?”
- What distilling costs: by my numbers, three kilowatt hours of electricity to distill one gallon, plus the cleaning.
- The drinking-water slides: the background figures I discuss before demonstrating my own kitchen-sink measurements.
- Upkeep: “If I can’t just set it forget it and walk away, I’m not interested.” I have not touched mine in about two and a half years.
- Questions from the audience: and a plain warning that it is a do-it-yourself project with no support from me.
