The GE FQK1R is a single-stage under-sink replacement filter cartridge designed for GE's GXK140TNN and GXULQR water filtration systems.

The unit is IAPMO certified to NSF/ANSI standards and features a twist-lock installation mechanism for easy maintenance.

The AQUACREST 3US-PF01 is a high-capacity replacement filter designed for Filtrete systems, offering tool-free installation and broad international safety certifications.
