Clean, healthy water for the whole house — with a higher flow rate for larger buildings
The IMT-U8 ultrafiltration unit uses membrane technology with a pore size of 0.01 micrometre. The membrane physically captures and removes bacteria, viruses, sludge, rust, algae, sediments, microplastics and nanoplastics from water. Unlike a UV lamp or chlorination, it does not just inactivate microorganisms but physically removes them from the water including dead cells. At the same time, it keeps all beneficial minerals (calcium, magnesium, potassium) in the water.
A UV lamp replacement — no electricity, no bulb costs
The IMT-U8 is a full-fledged UV lamp replacement with lower running costs. It works without electricity — powered only by household mains pressure (0.1–0.4 MPa). There are no costs for UV bulbs or regular radiation intensity checks. The PAN (polyacrylonitrile) membrane is hydrophilic and highly resistant to biofouling.
Higher flow rate — a solution for larger houses, hotels, guesthouses and pools
The IMT-U8 has a higher flow rate than the IMT-U7 and is designed for buildings with higher water consumption — larger family houses, guesthouses, hotels, offices and commercial premises. It is also ideal for filtering water for swimming pools and hot tubs, where it reliably removes algae, bacteria and sludge without chemicals.
Long membrane life
The PAN membrane lasts up to 36 months. The unit has a flushing system for captured impurities that extends membrane life. We recommend installing an IMT-M5 or IMT-M8 pressure regulator with a mechanical pre-filter upstream of the IMT-U8, which significantly extends membrane life and reduces how often it needs replacing.
Sturdy stainless steel construction
The brushed 304 stainless steel housing withstands both dynamic water hammer pressure and static pressure. The unit can be installed horizontally or wall-mounted using the supplied brackets.

FAQ
Everything you need to know about the IMT-U8
What is the IMT-U8 and who is it for?
The IMT-U8 is a powerful whole-house ultrafiltration unit with a PAN membrane with 0.01 micrometre pores. It is installed on the main water supply (point of entry) and filters all the water in the building. Thanks to its higher flow rate than the IMT-U7, it is designed for larger family houses, hotels, guesthouses, offices and commercial premises. It removes viruses, bacteria, algae, sludge, sediments and microplastics while keeping beneficial minerals.
What is the difference between the IMT-U7 and IMT-U8?
The IMT-U7 and IMT-U8 use the same PAN membrane technology (0.01 μm). The IMT-U8 has a higher flow rate (4,000 l/h vs 3,000 l/h for the U7), making it suitable for larger buildings with higher water consumption such as hotels, guesthouses, offices or larger family houses. The IMT-U7 is designed for standard family houses and flats. For the highest demands, there is also the premium IMT-U8 PSG version with a display, an integrated automatic shut-off valve and automatic flushing, designed by studio F. A. Porsche.
Will the IMT-U8 replace a UV lamp?
Yes, and it is more effective and cheaper to run. A UV lamp only inactivates (kills) bacteria and viruses, but their bodies remain in the water. IMT-U8 ultrafiltration physically captures microorganisms and removes them from the water completely, including dead cells. It also works without electricity, without replacing UV bulbs and without checking radiation intensity.
Is the IMT-U8 suitable for filtering water for a swimming pool or hot tub?
Yes. The IMT-U8 is ideal for filtering water for swimming pools and hot tubs. The PAN membrane reliably removes algae, bacteria, sludge and microplastics without chemicals. Physical removal of microorganisms by a membrane is more effective than chemical disinfection alone because it also removes dead cells and impurities that would otherwise remain in the water.
Will the IMT-U8 remove E. coli and coliform bacteria from well water?
Yes. The IMT-U8 membrane has 0.01 micrometre pores, while E. coli bacteria measure 0.5–5 micrometres, so they are 50 to 500 times larger than the membrane pore. The bacteria are physically captured and removed from the water. Ultrafiltration is more reliable than chlorination or UV radiation because it does not just inactivate microorganisms but physically eliminates them.
How does the IMT-U8 differ from the IMT-NC9 nanofiltration?
The IMT-U8 (0.01 μm) removes viruses, bacteria, sludge and microplastics, but does not remove chemical contaminants such as pesticides, pharmaceuticals, hormones or heavy metals. The IMT-NC9 nanofiltration (0.001 μm) removes these substances, but it is an under-sink solution for a single tap with a lower flow rate. The IMT-U8 is a whole-house solution that works without electricity. For maximum drinking water protection, the two systems can be combined.
How long does the membrane last and how is it replaced?
The PAN ultrafiltration membrane in the IMT-U8 lasts up to 36 months, depending on the quality of the incoming water. We recommend installing a pressure regulator with a mechanical pre-filter (IMT-M5 or IMT-M8) upstream of the IMT-U8, which significantly extends membrane life. For the highest demands, there is the premium IMT-U8 PSG version designed by studio F. A. Porsche, with a display, an integrated automatic shut-off valve and an automatic flushing port. Replacing the membrane is simple and can be done yourself.
Does the IMT-U8 need electricity or a booster pump?
No. The IMT-U8 works on normal household mains pressure (0.1–0.4 MPa) alone and needs no electricity or booster pump. This makes it cheaper to run, silent and almost maintenance-free compared with nanofiltration or reverse osmosis.
🔬 Scientific basis: The effectiveness of ultrafiltration in removing E. coli and coliform bacteria from well water has been documented by RNDr. Jiří Polman CSc., managing director of H2O nanotec, with reference to scientific literature (LeChevallier et al., Applied and Environmental Microbiology, 1988).
