Hi. I am a new homeowner in search for a water filter that has that alkaline properties. After reading through so many pages of post (skipping some), i can only conclude that i wound not want a filter that uses chemical to turn water alkaline. I had been approached by two different company: focuswater and hydroflux doing door to door sales. But realise both companies were not mentioned in this forum at all. Anyone has any comment on them? The more important question is, which filter should i choose?
