This built in filter was perfect for my 5 watt reverse osmosis system. It has two detachable quick connectors, one on each end. These connectors are reusable and can be used with other in-line filters of the same size. You must flush at least 2 gallons of water to release fine coal dust. The water tastes great and the flow is the same as with the previous built-in watt filter. If your system uses QC 3/8 connectors, please purchase this filter. You will be happy with that.
