The Short Answer
Use OEM bags when filtration matters, and aftermarket bags only when no contract specifies HEPA or IAQ. On a ProTeam, the intercept micro filter bag is part of the four-level HEPA system, so a cheap aftermarket bag can silently drop your capture rate and void compliance claims.
If your contracts are general commercial with no filtration requirement, aftermarket bags work mechanically and save money. The gamble is only a gamble when someone is checking the microns.
OEM vs Aftermarket, Decided
OEM bags match the machine's filtration spec and fit without fuss. On a ProTeam, the 10-quart intercept micro filter bag is a filter stage, not just a liner. OEM is the safe default for any fleet that documents HEPA.
Aftermarket bags are cheaper but may not match the capture spec or the fit. For general commercial work with no IAQ requirement, they are fine mechanically. The asterisk is compliance, not function.
An aftermarket bag that voids a HEPA compliance claim costs far more than the few dollars it saves, if it costs you a contract. Buy the bag your contracts require, not the one your purchase order prefers.
What This Means for Your Operation
Stock OEM bags for any ProTeam fleet that bids HEPA or LEED work, and consider aftermarket only for machines doing general commercial cleaning where no one specifies filtration. Keep the bag size matched to the machine, 10-quart for the CoachVac and LineVacer, 6.4-quart for the Hoover C2401.
