British Berkefeld stainless steel water filter

The British Berkefeld RVS water filter is a powerful outdoor water filter system that effortlessly purifies water from the ground, rivers or ditches into safe drinking water. More than 99.99% of bacteria are eliminated by the included ceramic Ultra Sterasyl filter elements retained! In addition, the British Berkefeld stainless steel water filter is able to filter lead and other heavy metals from the water.

✓ The British Berkefeld is supplied with 2 Ultra Sterasyl filter elements. These last for 6 months or 3000 litres in total.

Each filter element can purify approximately 28 litres per day. Because you have two filters in it at the same time, it is good for a total of 56 litres of safe drinking water per day. There is room for a total of 4 filters. The housing is made of high-quality polished stainless steel (stainless steel).

The ATC Super Sterasyl / Ultra Sterasyl filter

British Berkefeld ATC Super Sterasyl (nowadays Ultra Sterasyl) elements remove heavy metals, bacteria, chemicals and chlorine. The ATC Super Sterasyl / Ultra Sterasyl filters particles from 0.5 microns (this is 500 nanometers) with an efficiency of more than 99%. New filter elements that have not yet been used can be stored indefinitely.

The filter elements contain active carbon and resin and are made of silver impregnated ceramic, which makes them self-sterilizing. These elements therefore do not need to be boiled during use. If the flow rate of the filter elements decreases, you can clean them with a scouring pad. This removes the deposits that have formed on the outside, and the elements regain their original performance.

All water filters are manufactured according to ISO quality standards and are certified by NSF, NAD and WRAS. This guarantees that they meet the strictest international testing standards.
