Clearum HS Dialyzer

There is a difficult balance between removing toxins while retaining critical proteins. The Clearum™ HS high flux dialyzer can do both.1,5,6 Its performance is coupled with a BPA free design8 and reduced environmental impact,2-4 making it your dialyzer of choice.

The membrane that matters: safe,1 effective,1 green2-4,14

Clearum™ high flux steam sterilized (HS) dialyzers are standard hemodialysis dialyzers with a biocompatible membrane that provides adequate balance between diffusion and convection in HD, HF and HDF.1,5,6 Additionally, they have demonstrated usability on many machines on the market.7


  • BPA free8 : BPA is a highly protein bound toxin that is difficult to remove during dialysis. The Clearum™ HS dialyzer avoids this additional protein bound toxin9
  • Steam sterilization improves hemocompatibility10-12


  • Effective blood purification without critical protein loss1,5,6
  • Based on the sieving coefficient: retains essential nutrients and proteins1,5,6


  • Made of polypropylene: reduces final product weight14 and reduces carbon footprint by 60%2
  • Steam sterilized: avoids releasing ozone material into the environment4
