NSF 350 SYSTEMS | FAILURE FACTS
Greywater/Graywater filters destined to fail
A NSF 350 certification is worthless because NSF’s testing protocol does not include the real debris – hair and lint – found in real greywater.
Here is what real greywater has in it:

The greywater debris shown in the above pictures is from a commercial laundromat.
Nexus eWater from Australia was a perfect example of how completely worthless NSF 350 certification truly is.
Nexus eWater’s greywater systems passed the NSF 350 test and were certified by NSF to operate for 6 months without maintenance, but outside NSF’s laboratory the systems failed almost immediately from the hair and lint in real greywater.
Nexus eWater is now completely out of business, leaving a trail of abandoned customers with expensive systems that will never work.
Other companies now touting their own NSF 350 certifications will follow.
