Cutting-Edge Technology

The PURA STOP Filter Core is achieved thanks to our proprietary manufacturing process, which involves high-temperature fusion of materials to ensure they are united to form a single block. The technology of the materials and manufacturing provides the greatest rigidity, durability, and prevents the release of fibers into the water, features that are rare in conventional filters.

PURA STOP Filter Core technically has a larger surface area, increasing flow rate and improving filtration performance. Due to the quality of our raw materials, components, and advanced manufacturing process, PURA STOP is of technical grade, suitable for professional use without adding fibers to the treated fluid, or any taste or odor, making it ideal for applications requiring the highest quality liquid filtration.


PURA BIG STOP is designed for convenience and ease of installation. With no electrical connection required, this filter can be installed in a variety of locations, including outdoor settings.
PURA BIG STOP can be easily installed:

1. Before the elevated water tank.
2. Before a cistern.
3. Directly in the house’s water inlet pipe.
4. After the lifting pump from the cistern to the elevated tank.
5. After the pressurizing pump at the cistern outlet.
