Highest Quality Filters

The Clarity's Coldstream Filters are extremely powerful at filtering. They are even able to reduce fluoride (up to 97% - see test results). Doulton Super Sterasyl, Doulton ATC Super Sterasyl, and Black Berkey Filters do not reduce fluoride on their own, so you have to add extra filters (the PF4's for the Doultons and the PF-2's for the Black Berkey Filters).

This is a problem because they screw onto the end of the main filters and take up space in the filtered water chamber. They are also made of plastic so the plastic is then sitting in your filtered water, not nearly as good as Coldstream who have solved it through their more advanced filtering technology.

The Clarity Glass and Mango Wood Housing is a thing of simple beauty and was inspired by the fact that water should be in glass when possible.

Gravity Filtered Water... Drinking Water for Health

Gravity Water Filter for Fluoride Removal

While thousands of tons of fluoridation chemicals are added to public drinking water supplies each year, it's done despite a large body of government-funded research indicating that fluoride is neurotoxic and associated with lowered IQs in children as well as a significant increase in ADHD diagnosis in fluoridated communities. Experts in toxicology have likened the size of the effect to that from lead. Recent studies have also confirmed that fluoride toxicity can potentially lead to a wide-range of serious health problems – impacting your bones, thyroid, liver, kidneys, pineal gland, and even blood sugar levels. Fortunately, we have organisations like the Fluoride Action Network (FAN) who are helping to fight for the end of water fluoridation worldwide.

A powerful aspect of the Clarity's filters is that they reduce fluoride without using Activated Alumina which exchanges fluorides with aluminum hydroxide. The Clarity's Coldstream Filters use micro-ceramics to achieve this without migrating materials into the water through exchange making them far superior to older fluoride reduction technology. Fluoride consumption ought to be a choice, not a mandate!
