Yes. Kazee uses the universal 1/2-inch threading found on virtually every standard shower arm in North America. It installs by hand in about two minutes — no plumber, no tools, no tape required.

Unscrew your existing showerhead by hand, thread Kazee onto the shower arm, and hand-tighten. The built-in seal means no tools or plumber's tape, and a step-by-step card ships in every box. Most people are done in under two minutes.

Roughly every six months, or about 20,000 gallons. An indicator ring on the housing gradually changes shade so you always know when it is time. Replacement cartridges ship to your door on a schedule you control.

No. The micro-nozzle face plate is engineered to maintain — and usually improve — the feel of your flow, even while using less water overall.

Across fifteen stages, Kazee reduces chlorine, heavy metals such as lead and copper, hard-water minerals, rust, sand and fine sediment, then rebalances pH with mineral and vitamin-C media.

Orders ship within one business day from our U.S. warehouse, and most deliveries arrive within 3–5 business days. You'll receive tracking the moment your filter leaves the dock.

Anytime. Manage everything from your account — skip a delivery, change the frequency, or cancel in two clicks. No phone calls, no fees, no guilt trips.

Every Kazee filter is backed by a 90-night water-quality guarantee. If your skin and hair do not feel the difference, return it for a full refund — keep the cleaner water you already enjoyed.
