ORGANIC LOAD
Tersano LotusPro Findings by Type of Item
Given the soiling and residue on the various surfaces, it was surprising that the LotusPro device
removed the organic load so quickly; leaving the surfaces for each item measured with remarkable
ATP reductions.
For removing ATP, the LotusPro unit delivered superior sanitizing results overall, reducing ATP levels
by 91% on average for the items studies.
The Table below presents the percent ATP for the Items measured during the conduct of this
study.

Percent ATP Reduction
Somerset Academy Elementary
ATP reductions were very
effective for the items and
surfaces evaluated. The
organic load reduction
varied between 98% and
71%. Even at 71% for
student desks are likely to
exhibit continual re‐
contamination as a constant
touch point.
