i just wanted to put a little note in here to tell about my recent dealings with pure water club... I had a very pleasent and productive interaction with them... I had an issue with my filter not "turning off" so that water was continuiously comming out of the drain line of my filter... after discussing it on here, i contacted pure water club via email, gave them my order # from when i ordered my filter, explained the problems i was having(non stop water and increased TDS in the output).. after 2-3 emails confirming my issues, they sent me replacement parts, no cost... i installed the parts, and as far as i can tell right now(about 12 hours after installing the parts) everything is working just like it should... so, in conclusion, i have heard that pure water club may have had some issues in the past, but my personal experiences have been very pleasent.... +1 Pure Water Club.
