The Valleylab AirForce E3510 Prefilter (#901202-000) is a non-sterile, single use (disposable) replacement smoke prefilter for use with the AirForce Replacement ULPA Filter and AirForce System. It is recommended for low plume electrosurgical procedures. In the filtration system for the 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 HEPA prefilter removes particles down to 0.3 microns thus capturing a large percentage of the particulate matter. In the second filtration stage, the primary ULPA filter removes the remaining particles as well as the odors and gases associated with surgical smoke plume. The primary benefit to removing the surgical smoke in two filtration stages is that the prefilter ensures the optimum performance and useful life of the more expensive ULPA filter. Surgimedics prefilters are designed to provide visual indication that the prefilter needs to be replaced. When you notice that the top layer of the filter media is covered with dark brown or black sediment, it is time to change the prefilter. The useful life of a Surgimedics prefilter is recommended for single use. All prefilters are easily replaced, which can be quickly done during a procedure if necessary.
