Outdoor placement
Discharge should be positioned away from people and building openings. Weather and shared-property rules can affect the safe location.
Containment reading 26
Ask where collected air and particles will go
Review outdoor placement, then connect the observation to its source, system location, and a written scope.
DIRECT ANSWER
Start with the condition, not the sales package
EPA advises using vacuum equipment that exhausts particles outside or high-efficiency particulate air filtration when exhaust remains indoors. Either setup requires planning. Outdoor discharge should not blow debris toward an entrance, neighbor, open window, vehicle, or air intake. Indoor equipment needs suitable filtration, seals, maintenance, and placement.
The question is not only where the hose ends. Ask how the collector is transported through the home, how full containers and filters are handled, and how leaks or a power interruption will be managed.

What deserves a closer look
Indoor filtration
If exhaust stays indoors, ask for the filtration specification and how the unit is inspected for leaks. A generic claim of HEPA equipment is not a full containment plan.
Waste handling
Removed debris should remain contained during filter changes, machine movement, and disposal. The path through occupied rooms belongs in the preparation plan.
USE THIS SEQUENCE
Move from observation to a written decision
Choose the exhaust location
Review openings, neighbors, walkways, and outside-air intakes.
Confirm the filtration path
Ask what happens from duct connection through final exhaust.
Protect the travel route
Use floor and corner protection for hoses and collectors.
Plan interruptions
Ask how sections are closed if power, equipment, or weather stops the work.
