Filtered shower heads and universal shower filters designed to reduce chlorine and common impurities, plus 18-month kits that bundle the filter with two replacement cartridges. Installs by hand on a standard shower arm, no tools or plumber needed.

Which shower filter is right for you?

• Filtered shower head: replaces your current head. One part, a clean look, and a 15-stage cartridge built in.
• Universal inline shower filter: keeps the shower head you already have. It screws on between the shower arm and your head and works with most standard heads.
• 18-month kits and multi-packs: the filter plus two replacement cartridges, or 2- and 4-packs for every bathroom in the house.

How often to change the cartridge

Plan on a new cartridge about every 3 to 6 months, depending on how much your household showers and your local water. The shower head and the inline filter use the same replacement cartridge, sold in 2-packs or on a subscribe-and-save plan.
