NSF Study Finds AcornVac® Vacuum Toilets Show No Evidence of Bacterial Contamination from Toilet Plume
AcornVac® Vacuum Toilets Produce No Evidence of Bacterial Contamination from Flush Plume in NSF Testing
AcornVac Vacuum Sewage and Condensate Collection Systems have been certified by NSF International and carry an NSF-SE Listing.
Test: We provided NSF with a cistern flush toilet, a flush valve toilet, and two vacuum toilets for analysis of overspray and any associated contamination. E. coli bacteria was introduced to the toilets’ water supply, the overspray collected on Petri dishes surrounding the toilets, and the plates tested for the presence of E. coli colonies.
Hypothesis: Vacuum toilets introduce less overspray to the surrounding environment and are more sanitary.
Results: AcornVac’s vacuum toilets left no discernible traces of bacteria on the toilet seat, wall, or floor. Both gravity-flush toilets, however, generated detectable levels of E. coli on the toilet seat and the surrounding areas.
2022 Study Is First to Directly Measure Speed & Spread of Aerosol Flush Plume
A scientific study from the University of Colorado Boulder (CU) and covered by Fox News on Dec. 12 and 13 confirms that commercial toilets produce unsanitary plumes of germs and bacteria when flushed.
According to a write-up from CU Boulder Today , it “is the first study to directly visualize the resulting aerosol plume and measure the speed and spread of particles within it.” That means that for the first time, there is quantifiable data showing just how far the aerosolized flush plume can travel. These unsanitary flush plumes carry all sorts of undesirable germs and bacteria into the air, where they land on nearby surfaces and can be carried out of the restroom.
Our Blacklight Test Proves the AcornVac Difference
Compare the images of a commercial toilet and AcornVac toilet after flushing. The commercial toilet sprays visible droplets of unsanitary water onto the seat. The AcornVac toilet does not. Which would you prefer to use?
Our test report from NSF International confirms what you see: that “the two AcornVac vacuum toilets had non-detectable levels of overspray,” unlike the cistern and flushometer toilets.
Watch this video to see the test in action!
The video of the test echoes the findings of the CU study, showing a large flush plume emanating from a gravity-flush toilet and leaving droplets on the toilet seat. Gross! However, when the AcornVac toilet is flushed, there is no plume at all, and the toilet seat remains clean.

With so many harmful germs and bacteria in the world, it’s more critical than ever to take every safety precaution possible when it comes to minimizing their spread. An AcornVac vacuum toilet plumbing system should be a core component of every healthy building and a key component in minimizing disease spread.
