Yeah, the one at walmart is great, the last tds
reading was 6 ppm
. Not too bad at 33 cents a gallon. I only get 10 gallons a week though. Also, I live in an apartment and landlords tend to frown on DIY
. I really don't know, and maybe someone has the answer, how that machine can pump the water out so fast and have such low tds
. I fill one 5 gallon container in 3-4 minutes.
When I own a house, and a bigger tank, I will definitely invest in a RO
unit (and a dishwasher, but that's another story
) especially for drinking and cooking.
