How it Works
THE CONCEPT & FILTER ELEMENT EXPLAINED
Beautifully filtered water, in three simple steps.
The Claii water filter uses natural gravity to filter your drinking water. No electricity, plumbing or installation required. Read below to understand how it works.

1. Fill
Pour tap water into the upper chamber.
The water will go through the ceramic filter using nothing but gravity.
2. Filter
As the water slowly passes through the filter, unwanted contaminants are reduced while naturally occurring minerals like calcium and magnesium remain.
3. Enjoy
Fresh, beautifully filtered water collects in the lower chamber, ready to pour whenever you need it.
Simply refill the upper chamber to continue filtering.
The Doulton Ultra Sterasyl Replacement Filter.
Every Claii filter uses a Doulton® Ultra Sterasyl ceramic candle, made in England since 1826. Here are the independent laboratory reports for that element, including its NSF certification
What is the filter element made off?
The silver-impregnated ceramic shell physically removes bacteria, cysts, microplastics and fine particles, while the activated carbon and heavy metal reduction media adsorb contaminants such as chlorine, lead and many organic chemicals.
Antibacterial properties and silver are used to prevent bacteria from regenerating on the ceramic element.
How does it preserve the natural minerals?
Beneficial minerals such as calcium, magnesium and potassium exist in water as tiny dissolved, electrically charged particles called ions.
They are much smaller than contaminants like bacteria, microplastics and sediment, so they pass straight through the ceramic’s microscopic pores, keeping the natural minerals your body needs.
