Several years ago I bought one of these big glass ZeroWater Filters to "Watch the Water" with.

It does a nice job of making zero TDS (Total Dissolved Solids) water out of tap water as long as you keep a close eye on it with a TDS meter, changing the filter without delay as soon as the TDS starts measuring above zero, and clean everything fully every filter change.

Like a cat, I think water should move, so when I first put this together I thought it would be clever to also add a magnetic lab stirrer under the base to gently spin a Teflon coated magnetic pill inside the glass tank, causing the water in the tank to circulate clockwise perhaps 3 to 6 times a minute. (Adjustable)

Interestingly, during the last couple of filter changes I've noticed the need to clean some magnetically attracted black buildup off of that teflon coated pill magnet.

You can see a bit of it in the image on the right.

All water into our Covfefe Pot comes out of this this filter, so whatever our magnet is attracting out of our already zero TDS water, should not be adding to Dad's and my "attractiveness" by way of our beverage of choice, at least.

Curious about how the filtration systems do with saltwater, which is plentiful in the Gulf and nearby after the storm surge.

I vote for Berkefeld. Used in HI when the only water was catchment which was seriously undrinkable. Or any kind of city water etc. Right now we have clean well water so Berk is on a shelf for now.

Nuthin

We distill

You are also structuring that water. The stirring action may make up for the anger the water felt for being filtered. I’m not sure that having zero solids in the water is ideal, although I understand the thinking. Having “some” flavor is ok if it’s the right stuff (minerals). Does the black stuff wash off the Teflon or is it staining it? Curious if it’s patina like.

Side note: I have a ductless clothes dryer and the water it captures is 3ppm TDS. That’s darn near distilled, but it still has a slight detergent smell. Since I make the detergent, I don’t care. We use it in place of distilled for like the iron or steam mop. Distilled is hard to find these days at the grocery.

> So what’s in your water?

Sediment but I’m working on that. Nothing horrible and my water is totally neutral. When I top off my pool every Spring from the my well I have to add acid and alkaline. And in the Northeast that’s INSANE. 99% of people here have hard water.
