Inline Pureflow® Series
In-Line Filter System with an antimicrobial design, providing up to 90 days* of protection
InLine Pureflow® Blue is an advanced microfiltration system designed to reduce microbial contamination in water, including Legionella pneumophila, Nontuberculous Mycobacteria (NTM), E. coli, Salmonella, and other waterborne bacteria.
It features a replaceable 0.08 µm membrane filter cartridge securely housed within the unit, supporting consistent, high-efficiency bacterial reduction. When the filter reaches the end of its certified service life, simply unscrew and replace it with a new InLine Pureflow® filter to maintain uninterrupted filtration performance.
The InLine Pureflow® Blue system is equipped with pre-filtration technology, the InLine Pureflow® Red, a sediment strainer filter, designed to remove large particles from water and the InLine Pureflow® Green, a superior Carbon filter that reduces chemicals and odor while maintaining strong water flow. Its sterilizing-grade hydrophilic capillary membranes ensure long-lasting performance, retaining harmful microorganisms like fungi, protozoa, and bacteria without limiting water volume.
Designed for compatibility with all standard ½ size connector cradles and quick-connect adapters, the InLine Pureflow® Blue System combines a durable, reusable In-Line with a replaceable filter capsule, minimizing waste and lowering long-term costs. While this system enhances safety and hygiene, it should complement, not replace, local water testing and hygiene practices. Enjoy peace of mind with cleaner, safer water every time you shower.
Blue - a compact and reliable microfiltration unit engineered to reduce microbial contamination in water, including Legionella pneumophila, Nontuberculous Mycobacteria (NTM), E. coli, Salmonella, and other waterborne bacteria.
Product Applications:
The product comes in different modified versions:
-
Standard Version – Suitable for private homes, hotels, gyms, sports facilities, and restaurants
-
Specialized Version – Adapted for dental practices, outpatient clinics, and health-focused institutions
-
Portable Version – Ideal for field deployment by NGOs, emergency response teams, military bases, and civil support infrastructure
Red - Sediment Strainer filter
The sediment strainer filter is an essential filtration unit designed to remove large particles from water, thereby enhancing the lifespan of the Hollow Fiber system. It is equipped with Polysulfone membranes featuring pore sizes of 20 µm, and options for either 10 µm or 5 µm.
Product Applications:
The For-Filter is versatile and can be effectively used in healthcare, industrial, and residential settings, particularly in showers. It should be installed before the flexible piping, as illustrated in the accompanying images, or positioned prior to the In-Line system for optimal performance.
Green - Active Carbon filter
The Granular Activated Carbon (GAC) filter is a highly effective solution for purifying water by removing specific chemicals, especially organic compounds.
This type of filter excels in eliminating substances that cause unpleasant odors or tastes in water, such as hydrogen sulfide, which imparts a rotten egg smell, and chlorine. Its reliable performance makes it an excellent choice for enhancing water quality and sensory enjoyment.
Designed for use as an inline filtration solution to reduce exposure to waterborne bacteria within water systems. Independently tested to significantly reduce microbial load, including Legionella pneumophila, E. coli, and Pseudomonas aeruginosa. Suitable for environments with elevated water hygiene requirements.
* Filter capacity is influenced by local water conditions, the concentration of microparticles (SDI), and pre-filtration. SDI is measured according to ASTM D4189-95 standards. It is recommended to replace the filter cartridge every 90 days for optimal performance.
