Description

This replacement cartridge from Planets Own for the Smedur filter uses Ahlstrom + Activated Carbon, a filtration technology highly effective against contaminants like PFAS, with tests indicating that no residues remain after filtration with this combination. The Ahlstrom membrane is a relatively new technology developed by the Swedish-Finnish company Ahlstrom-Munksjö. This filter medium is one of the most effective we work with, capable of removing a variety of pathogens and pollutants, such as bacteria, parasites, viruses, endotoxins, pharmaceutical residues, microplastics, PFAS substances, and more.

Unlike traditional mechanical filters, this membrane operates through electro-adsorption by being positively charged, creating a barrier effect against extremely small particles, which tend to become more electronegative as they decrease in size. It functions similarly to the technology found in the Microspiral filters used in many of our other water purifiers. Although the membrane has a pore size of just over one micrometer, it can even capture viruses and other extremely small and hazardous particles at the nano-level, which can be up to 5,000 times smaller than a human hair! However, minerals and salts can pass through, allowing the purified water to retain all of its healthy properties.

The Ahlstrom membrane can be effectively used alongside other filtration techniques, and we now offer specially designed filter cartridges for Smedur with an Ahlstrom membrane that includes an activated carbon core, optimizing filtration performance. Insert the cartridge into the base of the filter housing, then reassemble the housing. Typically (if the water is not overly contaminated), the cartridge can last up to six months before needing replacement. Reduced water flow generally indicates the need for a new cartridge, and it should be replaced within six months regardless.

Q1: What contaminants does the Smedur replacement cartridge remove effectively?

A1: The cartridge removes bacteria, parasites, viruses, endotoxins, pharmaceutical residues, microplastics, PFAS substances, and more. It provides thorough filtration using a combination of Ahlstrom membrane technology and activated carbon.

Q2: How does the Ahlstrom membrane differ from traditional mechanical filters?

A2: Unlike traditional filters, the Ahlstrom membrane uses electro-adsorption with a positive charge to trap extremely small particles, including nano-sized pathogens and pollutants, while allowing essential minerals and salts to pass through.

Q3: How small are the particles that the Ahlstrom membrane can filter out?

A3: Although the membrane has a pore size of just over one micrometer, it can capture particles at the nano-level, such as viruses, which are up to 5,000 times smaller than a human hair.

Q4: How long does the Smedur cartridge last, and how do you know when to replace it?

A4: The cartridge typically lasts up to six months under normal water conditions. Reduced water flow indicates that it’s time for a replacement, and it should be replaced within six months regardless of usage.

Q5: Can the Smedur cartridge with Ahlstrom membrane be used with other filtration techniques?

A5: Yes, the Ahlstrom membrane can complement other filtration methods. The Smedur cartridge also includes an activated carbon core, enhancing its filtration performance when used in conjunction with other systems.
