Ecoline Duo Ultra
Effective 2-stage filtration with activated carbon and ultrafiltration
Ecoline Duo Ultra combines a coconut-based activated carbon block with a 0.01-micron hollow-fibre ultrafiltration membrane. The two filtration stages reduce chemical impurities, microorganisms and ultrafine particles without removing the water’s naturally occurring minerals.
Stage 1: Coconut-based activated carbon block
The first filtration stage features our antibacterial AB22 carbon block cartridge. It is designed to effectively reduce chlorine, pesticides, pharmaceutical residues, microplastics, selected heavy metals and PFAS compounds such as PFOA, PFOS and PFNA, along with a wide range of other potential impurities.
The compressed coconut-based carbon block also helps improve the water’s taste and odour.
Stage 2: Ultrafiltration down to 0.01 microns
The second filtration stage consists of a 0.01-micron hollow-fibre ultrafiltration membrane, which acts as a physical barrier against bacteria and very small particles.
The membrane helps retain bacteria such as E. coli, coliform bacteria, Salmonella and Legionella. It also provides additional filtration of microplastics, sediment and other suspended particles down to 0.01 μm—equivalent to 0.00001 mm.
Ecoline Duo Ultra reduces:
- Bacteria such as E. coli, coliform bacteria, Salmonella and Legionella
- Pesticides and herbicides
- Selected PFAS compounds, including PFOA, PFOS and PFNA
- Chlorine and unwanted tastes and odours
- Selected heavy metals
- Pharmaceutical residues and organic pollutants
- Microplastics
- Rust, sand, sediment and other fine particles
- A wide range of other potential impurities
The precise reduction depends on the individual substance, water composition, flow rate and how long the cartridges have been in use.
Benefits of Ecoline Duo Ultra
- Advanced 2-stage filtration: The combination of activated carbon and ultrafiltration provides broad, effective filtration of chemical impurities, bacteria and particles.
- Retains natural minerals: Calcium, magnesium and other naturally occurring minerals pass through the filter.
- No wastewater: The filtration process produces no wastewater, unlike traditional reverse osmosis.
- High flow rate: Delivers up to 6–8 litres of filtered water per minute, depending on the installation and incoming water pressure.
- Antibacterial carbon block: The AB22 cartridge’s antibacterial properties help limit bacterial growth within the carbon block.
- Robust EU-made filter housing: Manufactured from heavy-duty, BPA-free, food-grade materials.
