Wrapped in a microporous cloth, the carbon block filter serves a twofold purpose: sifting sediment while safeguarding the carbon's intricate honeycomb pores from particles. This ensures its filtration capacity is directed towards contaminants such as chlorine instead of being occupied by dirt. Through Nitrogen treatment, the carbon is activated, heightening the adsorption process to entice contaminants into the pores and firmly trap them there.

This fine layer serves as a preventative measure against limescale accumulation in hard water, repelling molecules that contribute to scaling while encasing surfaces to deter further scaling downstream. Additionally, this film acts as a barrier against corrosion by intercepting molecules carrying oxygen, thereby disrupting the oxidation that initiates rust and eventual corrosion on surfaces.

The published F-Guard capacity is\n        stated at 1.5 GPM (approximately 5.7 L\/min). Reduction performance and\n        cartridge life can change with flow, water chemistry and contaminant\n        concentration, so application-specific testing may be needed where a\n        defined result is essential.\n      \u003c\/p\u003e\n    \u003c\/details\u003e\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes the antibacterial housing disinfect the water?\u003c\/summary\u003e\n      \u003cp\u003e\n        No such claim should be made.

The\n        F-Guard has a published capacity of approximately 40,504 litres at the\n        stated test flow, while NanoCeram® is listed at 40,000 litres. Catalytic\n        carbon capacity varies sharply by contaminant: the published projections\n        exceed 60,000 US gallons for chlorine but 4,000 US gallons for\n        chloramine.

The PRO-III-XL uses Active Ceramics, a carbon block and a\n        KDF\/GAC filter.

The first-stage F-Guard filter is specifically designed to reduce\n        PFAS compounds, including PFOA and PFOS, together with fluoride and a\n        wider range of chemical contaminants.\n      \u003c\/p\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes the system remove bacteria?\u003c\/summary\u003e\n      \u003cp\u003e\n        The NanoCeram® stage is designed to reduce bacteria, cysts and fine\n        particles. The system must still be used with microbiologically safe,\n        adequately disinfected water and is not a substitute for correctly\n        specified UV treatment on an unsafe private supply.\n      \u003c\/p\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eWill the system deliver 70 litres per minute?\u003c\/summary\u003e\n      \u003cp\u003e\n        Not necessarily. Seventy litres per minute is the maximum rating of an\n        empty individual 20-inch housing. The F-Guard datasheet gives an optimal\n        flow of 15 L\/min. Actual output also depends on incoming pressure,\n        pipework and the condition of all three cartridges.\n      \u003c\/p\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eHow often should the cartridges be replaced?\u003c\/summary\u003e\n      \u003cp\u003e\n        Osmio recommends replacement approximately every 12 months. Replace\n        sooner if source-water quality, heavy consumption or falling pressure\n        and flow indicate that a cartridge is becoming exhausted or blocked.\n      \u003c\/p\u003e\n    \u003c\/details\u003e\n\n    \u003cdetails\u003e\n      \u003csummary\u003eDoes the PROMAX-III-XL soften hard water?\u003c\/summary\u003e\n      \u003cp\u003e\n        No. It does not remove dissolved calcium and magnesium.
