The T-Safe ultra filtration technique provides the user with safe, sterile water. 


Ultra filtration technique

Ultrafiltration filter

  • T-Safe® hollow fiber membrane filter is a 0.1 µm absolute rated ultrafiltration filter.
  • It has been tested and validated as a sterile grade filter for liquid filtration, as it has proven filtration at 0.2 µm pore size in accordance to ASTM F838-05 testing.

Quality control

  • The filters are manufactured in a controlled production environment to ensure a high and consistent quality.
  • Traceability through Lot and Batch numbers on all filters and further randomized sampling control with bacteria solution ensures 100% product quality.

State of the art uniform pore size structure ensures a sharp cut off point and good flow rates, even at low water pressure. T-Safe® filters are tested to deliver safe and sterile water thanks to the accuracy in production of the filter membranes and pore size structure.

The sharp cut-off point is proven by the validation in accordance to ASTM F838-05 for 92 days of >Log7 bacteria retention for Legionella pneumophila, Pseudomonas aeruginosa, and Brevundimonasdiminuta and fungi retention for Aspergillusbrasiliensis (99.99999%).

How it works

  • The T-Safe® filter consist of a large amount of very thin hollow fibers with millions of pores.
  • The water flows from the outside of the filter membrane wall to the inside. The filtered particles as bacteria and fungi are caught on the porous membrane wall while clean water flows inside of the hollow fiber and provides the user with safe, sterile water.


  • T-Safe® filters are intelligent with their great exploitation of a bigger surface than common filters.
  • The big area of membrane wall secures a longer life-time of the filter as it will take longer for particles and bacteria to build up and clog the filter.

Constant flow

  • Our effort to save water has led to our wide experience in designing shower products, which provide great showering comfort with a minimum of water consumption – only 6-8 liters per minute is our normal recommendation.
  • This has proven to be essential for the development of filters with a long lifespan.


More than 20 liters of water can pass through an unregulated filter depending on the water pressure.

Litres per minute

 A Tandrup constant flow regulator limits the water flow to 2, 4, 6, 8, 10 or 12 liters per minute, regardless of the water pressure.
