Smoke evacuation systems today use the most efficient type of filtration – ULPA (ultra low penetrating air) filters. These filters have an efficiency rating of 0.1 micron sized particulate at 99.9995%., meaning one particle out of a million measuring 0.1 micron will pass through the filter. Capture of the particulate matter in the filter is accomplished through the three standard collection methods – inertial impaction, interception and diffusion. Efficiency in filtering capability is one of the key factors when evaluating a smoke evacuator.

In addition to the type of filtration media used for capturing particulate matter, a smoke evacuator filter should also include activated charcoal for adsorption and deactivation of the odor associated with surgical smoke plume. Where the charcoal is placed within the smoke evacuator filter is very important. It should be placed last so it can adsorb the odor containing gases rather than act as a physical filter. All Surgimedics ULPA smoke evacuator filters contain 25% or more specialty blended, activated charcoal for improved odor removal.

Often overlooked in the evaluation of a smoke evacuator filtration system is the size and type of the prefilter, as this may have a significant impact on the actual cost per procedure. A properly designed prefilter should be able to filter larger particles, extending the useful life of the ULPA media contained within the smoke evacuator filter. It may also include a layer of charcoal media for odor adsorption. In smoke evacuation systems where the useful life of the ULPA media is measured by pressure differential rather than cumulative time, a replaceable prefilter can reduce the cost of maintaining a smoke evacuation system.

Surgimedics offers the most advanced filtration technology to ensure optimal performance at the lowest cost per procedure.

Surgifresh Protection Plus ULPA Filter

Surgimedics’ ULPA Protection-Plus Filter is designed for use in the Surgifresh Turbo smoke evacuation system. The purpose of the filter is to remove particulate, toxic gases and odor from laser plume or surgical smoke. While suitable for use in both laser and electrosurgical procedures, it is especially recommended for procedures that create offensive odor and gases, such as the odor created during laser hair removal.

Surgifresh ULPA Smoke Filter

Surgimedics’ ULPA Smoke Filter is designed for use in the Surgifresh Turbo smoke evacuation system. The purpose of the ULPA filter is to remove particulate, toxic gases and odor from laser plume or surgical smoke. While suitable for use in both laser and electrosurgical procedures, it is especially recommended for surgical procedures since the smoke plume created in this procedure type typically contains more particulate matter.

Surgifresh Prefilter

In the filtration system for the Surgifresh Turbo smoke evacuator, the removal of the particulate matter and odors found in laser plume or surgical smoke occurs in two filter stages. In the first filtration stage, the replaceable prefilter removes particles down to 0.1 microns at 99.9995% efficiency, thus capturing a large percentage of the particulate matter.
