Precautions to take when choosing to filter raw water in the water purifier Pure Filters

Coldstream FTO+ filters that are integrated into Pure Filters purification systems are fully capable of purifying reclaimed water.

However, certain precautionary measures are necessary:

  • Verify that there is no contamination with a specific pollutant that would not be detected by Coldstream FTO+ laboratory tests.
  • It is also important to minimize any contact of water with animal feces or chemicals from the roof.
  • Before being introduced into the purifier, the water must undergo pre-filtration to avoid any risk of rapid clogging of the filters.
