The Short Answer
HEPA matters when your contract requires it, and rarely matters mechanically otherwise. HEPA captures 99.97% of particles at 0.3 microns. A standard filter captures less. For a standard office or retail floor, the cleaning result is the same. The difference is documentation and eligibility.
Buildings that specify LEED, IAQ programs, or medical-adjacent standards name HEPA by name. If the bid document says HEPA, you show up with HEPA or you lose the contract. Filtration is a compliance checkbox before it is a cleaning feature.
The Filtration Ladder, Explained
A standard filter captures larger dust and debris and is enough for general floors where no one specifies air quality. It is cheaper to replace and perfectly adequate for most retail and light office work.
HEPA at 0.3 microns is the number LEED and IAQ programs reference. A four-level HEPA system, like ProTeam runs, keeps that capture rate stable even as the bag fills.
ULPA captures 99.999% at 0.12 microns. It is required for hospitals, cleanrooms, and pharmaceutical spaces. Unless the bid says ULPA, you do not need it.
What This Means for Your Operation
Buy filtration to match the contracts you are bidding on. A HEPA machine like the CoachVac qualifies you for the broadest set of standard commercial jobs. A ULPA machine like the LineVacer only pays for itself if healthcare or cleanroom work is in your pipeline.
