Three-stage filtration is not just a design preference — it is a cost and performance decision.
A single-stage system assigns the full collection burden to the HEPA filter. The result: faster loading, shorter filter service life, and higher per-job filter cost.
The INFILTRATOR three-stage architecture — used across the Mastercraft and Sootmaster lines — distributes that load across a collection bag, an intermediate filter, and the HEPA element. Each stage handles what it is engineered to handle, and each one extends the operational life of the stage that follows.
In practical terms: lower total filter cost per job, more consistent system performance across a service interval, and a HEPA filter that maintains its rated efficiency longer because it is not processing the full particulate load.
