The Watts MAXETW-975 is a premium replacement filter cartridge engineered for use with the Watts Maxetad-975 and compatible Watts Premier whole-house and under-sink filtration systems. It uses a high-grade coconut shell carbon block media to reduce chlorine taste and odor, sediment, sand, silt, rust, and other particulates, delivering cleaner, better-tasting water throughout your home or at your point of use.

The Watts MAXETW-975 features a 5-micron rating, effectively capturing fine sediment and particulates while allowing optimal water flow. This cartridge has a filtration capacity of approximately 15,000 gallons or a service life of up to 6 months, whichever comes first. Replacement intervals may vary depending on your household water usage and incoming water quality.

Yes, the Watts MAXETW-975 cartridge is tested and certified to NSF/ANSI Standard 42 for the reduction of chlorine taste and odor, as well as aesthetic effects. The cartridge is manufactured with FDA-compliant materials, ensuring safe contact with potable water and providing peace of mind that your drinking water meets rigorous industry standards.

The MAXETW-975 is specifically designed as a direct replacement for the Watts Maxetad-975 filtration system and fits other Watts Premier housings that accept this cartridge size. Always verify the model number of your existing housing before purchase to ensure proper fitment. Using the genuine Watts MAXETW-975 ensures optimal performance and maintains any applicable system warranties.

To install the MAXETW-975, shut off the water supply to your Watts filtration system, depressurize the housing, and unscrew the sump. Remove the old cartridge, insert the new MAXETW-975, and reseal the housing. Slowly restore water pressure and flush the cartridge for 5–10 minutes to remove any carbon fines before use. For best performance, replace the cartridge every 6 months or every 15,000 gallons, and sanitize the housing at each changeout.
