Nanofiltration IMT-NC9

The IMT-NC9 is an under-sink water purifier with a 0.001 μm nanofiltration membrane. It removes viruses, bacteria, chlorine, pesticides, antibiotics, hormones, heavy metals, nitrates, nitrites and microplastics. Unlike reverse osmosis, it keeps beneficial minerals (calcium, magnesium) and slightly raises the alkalinity of the water.

Reverse osmosis removes almost everything from water — including beneficial minerals. IMT-NC9 nanofiltration removes contaminants (pesticides, pharmaceuticals, heavy metals, bacteria, viruses) but keeps calcium, magnesium and potassium in the water. The result is naturally mineralised, slightly alkaline water.

Ultrafiltration (0.01 μm) removes physical particles — bacteria, viruses, algae, microplastics. IMT-NC9 nanofiltration (0.001 μm) is 10× finer and also removes dissolved chemicals — pesticides, antibiotics, hormones, heavy metals, nitrates. For chemically polluted water, nanofiltration is the more effective solution.

Yes, very effectively. Most pesticides have a molecular weight of roughly 200–400 g/mol, i.e. at or above the cut-off of a nanofiltration membrane. Their metabolites, which predominate in wells (e.g. the ESA and OXA metabolites of metazachlor or metolachlor), are also negatively charged and repelled by the membrane. Uncharged pesticides such as atrazine are captured by the C carbon cartridge. The weak spot is small uncharged metabolites, typically desphenyl-chloridazon – if a water test shows it at a higher concentration, we will recommend reverse osmosis. The EU drinking-water limit is 0.1 µg/l for each individual pesticide and 0.5 µg/l for their total.

Yes, most of them. The 0.001 μm membrane corresponds to a cut-off of roughly 200–300 g/mol, and the most closely monitored PFAS are larger – PFOS is about 500 g/mol, PFOA about 414 g/mol. In addition, the membrane surface is negatively charged and repels negatively charged PFAS molecules. For these substances, the scientific literature typically reports nanofiltration rejection of over 90 %, often around 99 %. The next stage is the C carbon cartridge, which adsorbs long-chain PFAS. Short-chain PFAS with small molecules (e.g. PFBA, TFA) are captured less well by nanofiltration – for those, reverse osmosis is more reliable.

We do not yet have a specific independent PFAS test of the IMT-NC9. PFAS are a group of more than ten thousand substances with different properties, so a single "PFAS efficiency" figure would be misleading. The efficiency is based on the physical principle of the membrane – its cut-off and electrical charge – and on published results for nanofiltration membranes.

Since 12 January 2026, EU drinking water has been subject to a limit of 0.1 µg/l for the sum of 20 monitored PFAS. On a public water supply, ask the operator for test results; for a private well, we recommend testing in an accredited laboratory. With low or undetectable levels, the IMT-NC9 is an excellent choice; where higher levels are confirmed, we will recommend reverse osmosis. Send us your results and we will advise you free of charge.

The version without a faucet is the standard configuration with no tap. The version with the SMART faucet includes a special matte-black tap with a display showing TDS and filter life, supporting Wi-Fi and the E-Water app. The SMART faucet dispenses filtered water only — it is not three-way.

The PPC and C cartridges are changed every 6–12 months. The NF nanofiltration membrane lasts 24–36 months. The unit monitors filter status automatically and alerts you on the display when a change is due.

A filter change takes 5 seconds thanks to the bayonet lock — no tools needed. Simply shut off the water supply to the unit, open the filtered-water tap to release the pressure, swap the cartridge and turn the supply back on.

Yes. The IMT-NC9 reliably removes bacteria, viruses and the chemical contaminants typical of well water — pesticides, nitrates, heavy metals — while keeping minerals. H2O nanotec offers a free consultation based on your water test.

Yes. The IMT-NC9 removes microbiological contaminants and the vast majority of chemical pollutants while keeping minerals. The result is clean, naturally mineralised, slightly alkaline water — suitable for everyday drinking, preparing baby food and cooking.
