The Watts Kwik-Change cartridges are easy to change with just a single 1/4 turn. No filter sumps, no mess, and the double O-rings prevent leakages.

Kit includes:

• (2) 13″ Sediment Prefilters (WQCSC13)
• Changed every 6 months
• (2) 13″ Carbon Block Prefilters (WQCCC13)
• Changed every 6 months
• (1) 13″ Hollow Fiber UF Membrane (WQCHFC13)

These water filter replacements and ultrafiltration membrane are not compatible with the Watts Premier Kwik Change UF3 Ultra Filtration System which are 10″ filters that are keyed differently.
