Osmio 4.5 x 10 Inch 10" F-Guard PFAS/Fluoride Filter 2 micron

Specialist 2 micron replacement cartridge Target PFAS, fluoride and a broad range of chemical contaminants The Osmio F-Guard is a specialist 4.5 × 10 inch filter cartridge designed for point-of-use, point-of-entry and industrial filtration applications. Its multi-media carbon block combines two activated carbons with zeolite minerals, metal scavengers and activated mineral phosphates. Advanced multi-media filtration More than a standard carbon cartridge The F-Guard uses a composite block engineered for adsorption and contaminant reduction across several media types. Its 2 micron rating also helps capture fine particulate matter while maintaining a low initial pressure drop at the stated test flow. Targets PFAS, PFOA, PFOS and fluoride Reduces chlorine, chloramine, lead and heavy metals Helps reduce VOCs, THMs, pesticides and herbicides 2 micron filtration rating Suitable for compatible 4.5 × 10 inch housings 2µ 2 micron rating Fine filtration within a specialist composite block. 92% Fluoride reduction More than 92% under the stated test conditions. 95% PFAS reduction More than 95% reduction stated in the datasheet. 7.5 Optimal flow 7.5 litres per minute for the 10 inch cartridge. Published contaminant reduction Performance stated in the Osmio technical datasheet The following figures are manufacturer-published reduction claims for the F-Guard media under the stated test standards and conditions. Real-world performance and cartridge life depend on the incoming water, flow rate, contaminant loading and installation. >99%PFOA and PFOS Fluorinated organic acids. >95%PFAS Per- and polyfluoroalkyl substances. >92%Fluoride Including fluorosilicic acid, sodium fluorosilicate and sodium fluoride. >99%Chlorine and chloramine Chloramine tested with a 3 ppm challenge. >99%Lead Specialist metal-reduction media. >98%Heavy metals Published broad heavy-metal reduction. >98%VOCs and THMs Volatile organics and trihalomethanes. >98%Pesticides and herbicides Also more than 98% glyphosate reduction. >99%Pharmaceutical compounds Referenced against ANSI/NSF Standard 401. >99%Microplastics Published reduction under the stated test conditions. >94%Radionuclides Published reduction under stated conditions. >92%Nitrates Published reduction under stated conditions. Capacity and flow Two different capacity ratings for different contaminant groups The figures below should not be treated as interchangeable. Replace the cartridge when the relevant rated capacity is reached, or sooner if water quality or flow deteriorates. 11,000 litres PFAS and fluoride reduction Approximately 3,000 US gallons under the manufacturer's stated conditions. 40,504 litres Lead, mercury, chloramine and chlorine Rated at 5.68 litres per minute, equivalent to 10,700 US gallons at 1.5 GPM. ✓ Check the housing and required flow Nominal 4.5 × 10 inch cartridge format The cartridge measures approximately 107 mm in diameter and 241 mm long, with a 34.5 mm internal diameter. Confirm that your housing accepts this format and that the 7.5 L/min optimal flow suits the intended application before ordering.

Shop Osmio Helpful answers Frequently asked questions Does the F-Guard reduce fluoride?Yes. The Osmio datasheet states more than 92% reduction for several common fluoride forms, with a stated PFAS and fluoride capacity of approximately 11,000 litres for this 10 inch cartridge. Does it reduce PFAS?The datasheet states more than 95% PFAS reduction and more than 99% reduction of PFOA and PFOS under the referenced test conditions. How long does the cartridge last?There is no single calendar lifespan stated in the datasheet. Capacity depends on the contaminant group: approximately 11,000 litres for PFAS and fluoride, and approximately 40,504 litres for lead, mercury, chloramine and chlorine at the stated flow. Water quality and use can shorten service life. Will it fit any 4.5 × 10 inch housing?Do not assume compatibility from the nominal size alone. The cartridge is approximately 107 mm in diameter and 241 mm long with a 34.5 mm internal diameter. Confirm the housing specification before ordering. Can it be used as a whole-house filter?Osmio lists point-of-entry use as an application, but the 10 inch cartridge has an optimal flow of 7.5 L/min. Compare this with the property's peak simultaneous demand; a larger cartridge or multi-stage system may be more suitable for higher flow requirements. Does it soften water or prevent limescale?No. This is a specialist contaminant-reduction cartridge, not an ion-exchange water softener. It does not remove the calcium and magnesium hardness responsible for limescale. Friendly expert support Need help confirming the correct cartridge and housing?
