Keep your Arius shower system performing at its best with genuine sediment filter replacements, shower filter replacement cartridges, and softener replacement filters designed specifically for the Arius water filtration and softening system. Unlike ordinary shower filters that only target chlorine, Arius combines a high-performance filter cartridge with a true, resin-based water softener and each component needs periodic replacement to keep delivering clean, soft water.

The sediment filter replacement removes rust, dirt, and particulate matter before it ever reaches your skin and hair, protecting the rest of the system and keeping water flow smooth. The shower filter replacement cartridge tackles chlorine, VOCs, heavy metals, and other contaminants that can dry out hair and irritate skin. The softener replacement filter restores the resin media responsible for removing hard water minerals like calcium and magnesium — the real cause of dull hair, dry skin, and mineral buildup on fixtures.

For best results, Arius recommends replacing your filter roughly every 90 days (a 30-second swap) to maintain optimal filtration and softening performance. All replacement filters are independently lab-tested and built to the same standard as the original Arius system, so you can count on consistent results, shower after shower.
