Our verdict

A cartridge shower filter that adds chlorine reduction without replacing your current head. It does not include a head, and it must be replaced on a schedule.

ASIN: B00AM17776Model: AQ-4100NSH

Overview

A bed of KDF copper-zinc media and coconut shell carbon fills a cartridge placed between the shower arm and your own head. Water flows through it on its way to the head.

Installation needs no plumbing skills, and you run water for several minutes after fitting to flush the cartridge. Filter life is limited by gallons or months, whichever comes first. The weight entry is unusable, so check size before ordering.

Who it's for

People with hard-to-please hair or skin and a shower head they like will use the add-on cartridge. Those who want a head included, or who have non-standard arm threads, should look at a bundle.

Performance notes

KDF copper-zinc media and coconut shell carbon work together to reduce chlorine and other impurities. Contact time and flow rate decide how much is removed, which is why a maximum flow rate and a gallon rating are published.
