I am not taking any changes on tap water. It may test o.k today and not be o.k. tomorrow. I also do not use water from my frig nor ice from my frig or any ice unless it is from my filtered and boiled water.

I have a Zero plastic container and. use Zero filters. A filer will last me about 3 or 4 weeks. After filtering the water to get out all the particles, then I pressure it in my InstantPot for 14 minutes. That is more than necessary because I am almost at sea level. The Zero Filter comes with a meter to measure the particles before and after. It is amazing!! it tells you when to replace your filter. I start checking my water after filtering in about 3 weeks after putting in a new filter. I change when the ppm is 10.
It is a production to get use to but it is just part of my daily routine and has become simple with the Instant Pot. and a large 2 gallon ceramic jug with a faucet on it.
I average using 2 or 3 gallons a day.
