The experts may know it all but for the commoner, the discussions and options are baffling without some clear answers. If would be nice if the collective wisdom here would narrow it down to the top 5-10 configurations and the topic is stickied for all new inquiries but clear choices are hard to find even after going through lengthy threads.
I find an opinion: "Whatever system brand you choose, make sure it uses a standard Dow style membrane and standard 2x10 prefilter housings. DO NOT purchase a system with proprietary cartridges." Which makes sense but how does one know that any given system uses Dow style membrane and where does one find the pre-filter housing sizes if they are rarely mentioned in the specifications?
To make matters more confusing, The Consumer Reports issue of January 2022 lists 4 preferred systems for under-sink installation but none of these seems to have a RO component. I even find a single cartridge filter system from the well-regarded Impact Water Products. Their Solo 1 has a unique 3-stage cartridge but its daily purification capacity is 5-10 times what an average household like mine requires. What are the circumstances under which RO is necessary for city-supplied water?
Some of our experts advise buying only US-made products but where can one find US-made water purification systems when most manufacturing has been outsourced to countries with cheap labor?
Over the years I have benefited tremendously and learned much from these forums. Please forgive me for my expression of helplessness but all I am hoping to find are some concrete recommendations for a kitchen water purification system for my city-supplied (soft) water that does not waste more water than it produces in purified form, serves our needs for drinking and cooking at about 5-10 gallons per day, and uses non-proprietary filters. Is that too much to hope for without having to learn the science of water purification and doing plenty of research worth publishing in an industry journal?
Thank you all for your insights.
