With a prefilter, tap water quality can be improved significantly. That is why the German DIN 1988 Codes requires that prefilters be installed in every household.

 100% healthy & lead free

2.5 times more efficient than comparable devices.

Made of ultra-durable bullet-proof PC material


  1. Removal of impurities
  2. Preventing secondary pollution
  3. Environmental friendliness and cost effectiveness
  • Filter performance: Studies show that particles over 40um account for merely 3% of the total pollutants, but 60% of the total area. For a water purifier, losing 60% of working area will lead to significantly reduced water flow, filtration efficiency and service life.
  • Removing impurities and safeguarding your health

Installed before the water inlet to the house, a prefilter can remove precipitate impurities, microbial debris, iron rust, sediment, dust and other large particles from the pipe. It can also prevent secondary pollution and waterborne diseases.

  • Environmental benefits: Enhanced filter performance and service life will be environmentally friendly and cost-efficient.

Anti-scaling feature for pipes (MW04-08S): Optional anti-scaling feature for pipes
