Mode of Operation
The PlumeSafe Whisper 602 Smoke Evacuation Filtration System is designed to remove smoke
and noxious odors from the smoke plume generated while performing laser and electrosurgical
procedures.
These evacuation systems are designed with high suction and high flow rate centrifugal action
pumps. The ultra-quiet motor is used to draw the smoke plume from the surgical site through the
vacuum tubing and into the ViroSafe®filter where the smoke plume is purified by a series of
filters and carbon. A single disposable filter is used to simplify the installation and removal during
filter changes. This filter is completely enclosed to further protect the healthcare personnel from
potential contamination. The ViroSafe® filter contains four different filter stages within a single
housing to decontaminate the smoke plume.
The ViroSafe®filter is used with the PlumeSafe Whisper 602 Smoke Evacuation System.
The first stage of filtration is a pre-filter whose function is to trap and remove gross particulate
and casual fluid, while capturing some micro-organisms.
The second stage of filtration is a VLSI (Very Large-Scale Integrated) grade ULPA (Ultra Low
Penetration Air) high-tech, patented1filter designed to capture particulate and micro-organisms
down to 0.01µm at an efficiency of 99.99995%. Each ULPA filter is pre-tested and certified
before use and is impregnated with a chemical agent.
The third stage of filtration uses virgin coal grade activated carbon for the removal and
adsorption of odors and toxic gases produced by the burning of tissue. These harmful gases are
a health hazard to those healthcare workers who breathe them. For this reason, the highest
quality virgin coal grade activated carbon is used. This activated carbon preferentially removes
toxic organic gases rather than water vapor.
The fourth stage of filtration is an expanded foam and filtration media, both of which are also
impregnated with a chemical agent, used to trap activated carbon fines from migrating out of the
filter.
