Key benefits and features

• Premium materials and design provide robust adsorption to capture particulates like sediment, rust, silt, sand, and iron.

• Long-lasting performance with an estimated life up to 15,000 gallons, and replacement every 3–6 months depending on water quality and usage.
• Easy installation and DIY-friendly replacement; a 6-pack provides convenient, ready-to-use cartridges when you need them.
