Overview
A reverse osmosis membrane inside a plastic housing treats tap water in the cabinet below the sink and passes it to a single tap. The listing gives its capacity and weight but no flow, drain ratio or parts list.
A recognized brand and a standard reverse osmosis build make this a familiar format. The capacity rating is on the low side for a family, and the listing leaves out the details that would help compare it with other systems.
Who it's for
A small household or couple with an under-sink cabinet and an interest in reverse osmosis fits the format. Larger families and anyone who needs flow and certification data should look at a better-documented system.
Pros and cons
- Reverse osmosis purification
- Heavy for its capacity rating
- Flow rate not stated
- Included parts not itemized
Performance notes
The membrane rejects dissolved solids under line pressure, and capacity describes how much water it treats before service. Output speed depends on supply pressure and water quality, which the listing does not give.
