Water purification system utilizing a carbon block pre-filter

This water purification system cleans water using a carbon block filter followed by a reverse-osmosis (RO) filter. Untreated water first flows through the carbon filter, then into the RO filter, which is wrapped around a central tube. Purified water then exits through the central tube.

Why it matters: Since 2004, manufacturing for compact, integrated filter cartridges has advanced, improving viability.
