Water filter cartridge Filter Logic FL402 replacement pack of 4

Filter Logic FL402 replacement pack of 4 cartridges provides a straightforward option for maintaining compatible household water filtration systems. These replacement cartridges are designed to fit systems that accept the FL402 model and perform mechanical and/or chemical filtration depending on the system configuration. They are intended to reduce suspended particulates, improve clarity and taste of tap water, and support everyday kitchen and drinking water use when installed according to manufacturer guidance.

Advantages

The four-cartridge pack reduces the need for frequent individual purchases and ensures consistent filtration performance across multiple change intervals. Each cartridge is manufactured to match the dimensions and connection type of FL402-compatible housings, enabling easy drop-in replacement. The filtration action targets particulates and common taste and odor contributors found in municipal and well-supplied tap water, helping to deliver clearer, better-tasting water for cooking and drinking.

How to use

Before installation, shut off the water supply to the filtration system and relieve system pressure by opening the nearest faucet.

Insert the Filter Logic FL402 replacement cartridge into the housing with the correct orientation until it seats securely, then reassemble the housing and slowly turn the water supply back on while checking for leaks. Run water through the system for a short period to purge air and any loose particles before normal use.

Usage recommendations

Replace cartridges according to the filtration system manufacturer’s recommended interval or sooner if flow rate decreases or water quality changes. Use potable water only for flushing and follow local guidelines for disposal or recycling of used cartridges. For optimal performance, inspect seals and O-rings during each change and replace them if worn.
