Are you refering to a tap water purifier? If so they do produce comparable
quality water as an RO unit however they are more expensive in the long run
as the cartidges need to be replaced as they become saturated.
You can now buy RO units that process a large amount of water per day (65
gallons and up) starting around $200 if you shop around. The waste water can
be used to water other plants that are not as sensitive to salt buildup (such
as outdoor plants).
I would recommend a TFC membrane if you are going to purchase a RO unit.
These membranes work better at removing the salts in the water than the CTA
membranes.My two cents,
Ed
