Re: DI water (was APD V3 #724
Before you invest in a deionizing unit, check how many gallons of your
water will each cartridge process. That and the price of a replacement
cartridge will give you cost/year (if you do, say, 25%/week water
Your other choice is Reverse Osmosis, which over 2-3 years might turn
out to be less expensive.
Have a Merry Christmas and a Happy New Year!
