Dechlorinating Shower Filter (RS-502) Cartridge and Housing (No Shower Head)


Dechlorinating Shower Filter (RS-502) Cartridge and Housing (No Shower Head)


For a Healthier, More Enjoyable Shower… The Rainshow’r® Way


The RS-502 is a non-cartridge filter which converts chlorine into a harmless soluble chloride. This unit has a sealed back unit and comes with a back flush adapter so it can be reversed when needed to flush out collected contaminates and particulate matter. These units can be modified for particular environmental applications such as low or medium water pressure, making them appropriate for overseas applications.

This product does not include a shower head. For a more complete model, see our CQ1000 filter with chrome head or massage action head OR upgrade the head to a Bernouli Power Shower low flow shower head.
