InSinkErator F-1000 Replacement Water Filter Cartridge for Under-Sink Systems

Clean, great-tasting water from your kitchen sink

The InSinkErator F-1000 Replacement Filter Cartridge is designed for exclusive use with InSinkErator water dispensing systems. When paired with compatible models, it helps reduce particulates and chlorine taste and odor, offering water that tastes crisper for beverages and daily hydration. With a 500-gallon rated capacity, this cartridge is built to support regular use without frequent changes, making filtered water more convenient at home.

Designed to fit under-sink installations, the cartridge measures about 11.75 inches long by 2.25 inches in diameter, a compact size that fits neatly within standard filtration housings. The result is water that can be perceived as cleaner and fresher, especially when drawn directly from your drinking water dispenser or mixed with hot water from a compatible system.

Key benefits at a glance

• Reduces particulates and chlorine taste and odor to improve drinking water quality.
• Economical 500-gallon capacity supports longer use between changes.
• NSF standard 42 certification provides quality assurance while maintaining system performance.

Compatibility and setup

Use this cartridge with the F-3000S, F-2000S, or F-1000S water filter systems for best results. Note that the F-1000 cartridge is not compatible with the SST-FLTR Stainless Steel Tank & Filtration System. For a complete filtered-water experience, consider pairing a compatible IN-SINK-ERATOR instant hot water tank and a multi-feature faucet to deliver both filtered hot and cold drinking water from a single tap.

Eco-conscious choice

By enabling filtered water at home, you may reduce reliance on single-use plastic bottles, contributing to less waste and a lower environmental footprint over time when used as part of a regular hydration routine.

Replacement cadence: For optimal performance, consider replacing every six months at the rated capacity or sooner if you notice a drop in flow-rate or changes in taste. This helps maintain filtration effectiveness and overall system performance.
