Re-mineralize with various things.. either the lime I guess - or a few drops of crystal salts, about a dozen grains of organic rice will also do it, or
what-have-you.
You can also let it sit in the sum for energizing and drop a crystal in the jug.
I decided on the Aquasana, but there are a few good models. I got one even tho I don't have chlorine, I have well water..
but these days I don't trust any water or the air, sad to say.
