Beware of the many cheap copies that invade the market: some systems look the same, but are not equal.

At Pure Filters, we have chosen rigour. Our Coldstream filters are manufactured in Europe, tested up to 3000 liters by an independent  laboratorywith full traceability. A credible alternative to superficially tested Asian clones.

Pure Filters, autonomy through quality.

We are proud to present our selection of gravity filtration and purification systems Pure Filters equipped with Coldstream FTO+ cartridges and proven Berkey purifiers, each offering an elegant and efficient solution for achieving pure, healthy water without relying on electricity or complex plumbing systems.

Become self-sufficient in clean and healthy water.

Even if normality is disrupted. Filter and drink water from a lake, river, rainwater or well thanks to mechanical filtration and high-performance adsorption. Our Pure Filters range allows you to treat tap water and outperform bottled water quality, while reducing your environmental footprint. Check out this detailed article on this subject. 

Many gravity filters have been available on the market since the end of the Black Berkey manufacture. We invite you to consult this guide to help you make your choice while finding scientific data.

Warning: the conflict between Berkey and the EPA in the US has led to the appearance of many imitations of unreliable systems. Check out our full analysis of these Black Berkey filter copies.

In a world where the quality of tap water and bottled water is becoming increasingly uncertain, being self-sufficient in drinking water is essential to protect your health. Pollution problems, chemical contaminants and endocrine disruptors are all risks that can affect the quality of the water we consume daily.

Pure Filtersgravity purifiers, equipped with Coldstream FTO+ cartridges, offer a reliable and efficient solution for obtaining filtered and quality water, suitable for different types of water. 

Protect your health from water quality issues

Tap water, although treated, can still contain unwanted contaminants such as heavy metals, pesticides, and pharmaceutical residues. In addition, aging pipes can introduce additional impurities.

As for bottled water, it is not without its problems. Plastic bottles can release microplastics and other harmful substances into the water, affecting its quality.

Drinking water autonomy: security in the event of a crisis

In the event of a disruption of normality, such as natural disasters, power outages or water shortages, it is crucial to be able to rely on a reliable source of drinking water.

Gravity water purifiers are designed to operate without electricity, simply using the force of gravity to filter the water. Whether you're out in the wilderness, camping, or facing an emergency, these purifiers can turn river, lake, or rainwater into clean, drinkable water.

Advanced filtration technology with Coldstream FTO+

The Coldstream FTO+ cartridges built into our Pure Filters purifiers use a combination of high-quality ceramic and activated carbon to effectively remove a wide range of contaminants. They are specifically designed to provide additional protection against nitrates, a benefit that few other filters can claim.

An ecological and economical solution

Opting for Pure Filtersgravity purifiers also means making an ecological and economical choice. By reducing your reliance on bottled water, you are helping to reduce plastic waste and protect the environment.
