In January 2023, WaterFleet’s mobile water treatment system underwent rigorous challenge testing at the National Sanitation Foundation (NSF) in Ann Arbor, Michigan. The goal: determine if our mobile system could disinfect contaminated water to levels that meet or exceed the safety standard of boiling water—a long-trusted method for emergency potability.
So, is the mobile water treatment system better than boiling water? The results are in, and they’re independently verified.
NSF Challenge Testing: What Was at Stake?
The NSF, a globally recognized, ISO-accredited organization for public health standards, put WaterFleet’s mobile system through a 3-day gauntlet to test its effectiveness against microbial contaminants, including:
-
Viruses
-
Bacteria (e.g., E. coli)
-
Protozoa
The challenge? Could the mobile water treatment system remove 2 to 6 logs of contaminants (99%–99.9999%)—matching or outperforming the disinfection level achieved by properly boiling water?
Spoiler: Yes, it did. In every test scenario—with and without chlorine, with multiple processes toggled—the system met or exceeded the boiled-water benchmark.
How the Mobile Water Treatment System Performed (and Outperformed)
Tested Without Chlorine
Even without chlorine disinfection (which WaterFleet always uses in practice), the system passed the NSF’s toughest microbial thresholds. That means it builds in redundancy, even in suboptimal field conditions.
Chlorine Scenario Would Surpass Standards
With chlorine added, the system would’ve qualified for an additional 3-log removal credit for viruses and E. coli. That pushes disinfection well beyond what boiling water achieves.
Limitations Were in the Lab, Not the System
Had the NSF been able to load higher concentrations of contaminants into the test water, the mobile water treatment system would have achieved even higher log reductions. In short: the system outperformed the lab’s maximum stress levels.
Proven by Science, Powered by Values
After nearly a decade of serving thousands of workers and delivering millions of gallons of potable water, WaterFleet’s confidence in our mobile water treatment system is now backed by indisputable, third-party evidence.
We’ve always stood behind our Core Values—now we have NSF-certified data to back up what our customers already know: WaterFleet’s technology delivers.
So is the mobile water treatment system better than boiling water?
The evidence speaks for itself.
