About
I test shop vac systems against actual messes: silica, drywall dust, and slurry. My benches track CFM, sealed suction, and hose losses so recommendations reflect reality, not labels. Expect data, tolerances, and clear pass/fail thresholds.
Core Beliefs
Performance is a system; the weakest link sets the result.
Background
During a bathroom demo, our first vac choked on fine silica, then leaked through a 'HEPA-style' bag. The only setup that worked was a true HEPA bag, pre-separator, and a tight 27 mm hose. After that day, I started measuring CFM and sealed suction with gauges, not guesses.
Perspective
I favor measurable airflow and containment over brand loyalty.
