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.

HEPA Vacuum Shop Vacs: Allergy Dust Control for Woodshops
Build a woodshop dust-control setup that truly contains fine dust by verifying loaded CFM, true HEPA certification, and using a three-tier system. Get the exact airflow thresholds, hose and pre-separator upgrades, and tested vac picks that meet compliance.
Comparisons & Key Decision Factors
5 Gallon vs 12 Gallon Shop Vac: Which Size Fits Your Workshop?
Stop choosing by tank size alone - match airflow, filter, and hose setup to your actual debris load. Use the decision rules to know when a 5-gallon's mobility beats a 12-gallon's capacity and how to maintain suction across dust and wet cleanup.
