13 Inch Kwik-Change™ Filter Cartridges are intended for Replacement in Watts Kwik-Change System WQC4RO13-100 or AMI Simple Change RO Sytem 100SC. The WQC-13 filters a direct replacement for RSC-100- filters, which have been discontinued.  The filters are identical in size, performance, and quality - the key difference is the appearance of the branding on the labels.These filters will NOT fit the Watts Premier RO Pure RO-4 Reverse Osmosis System.

*This replacmeent schedule is an estimate only. Poor water quality requires more frequent maintenance, and better water quality may allow longer filter cartridge and membrane life. Generally speaking, replacement should be performed as needed based on any drop in system performance.
