That is the subjective question. What exactly "compares" falls into the relatively small market of "believers" about AQLV.
I'm not wrong and totally right, there are good systems that filter water to very acceptable high standards for a lot less. I'm in the market side and that is what counts. The ones who put out the money to buy any system.
AQLV's only issue is how they can "sell" the product and how many of people like me that would "believe" that it is prudent to spend that kind of money when one can get plenty or in the view of the same or better for considerably less in an economy that will not recover for years.
