DREO RO Water Filter 112 Countertop Reverse Osmosis System

System: The DREO RO Water Filter 112 is a countertop reverse-osmosis water purifier with a 3-liter capacity, TDS monitoring, and an autofill pitcher. Its no-plumbing format suits buyers who want an in-kitchen unit, while the listed 3-liter capacity and mixed feedback on dispensing speed make throughput and pitcher size worth considering.

What to know before buying

Listing details to confirm

Listing details are inconsistent about size and filter life: the table lists 3 liters and a 6-month filter cycle, while feature text describes a 3L tank plus 1.1L pitcher and a filter lasting 265 gallons (1000L), the manufacturer also gives two slightly different dimension sets. Confirm the capacity and replacement interval for the selected version. The listing claims reductions for specific contaminants and says it was SGS-tested to meet NSF/ANSI 58, but these are manufacturer statements, not independent verification here. Customer feedback also reports mixed opinions about pitcher size and dispensing speed.
