The first field guide
A small team mapped the recurring questions that appear before a filter is removed: access, fit, airflow direction, and records.
About the studio
Useful knowledge for the moment a filter needs changing.
Subtelio Airwise began as a field-notes project for people who wanted a clearer way to approach routine air-system upkeep. We turn observations from real maintenance environments into structured, approachable learning paths.

Scenario-based lessons
The curriculum expanded into short, focused courses for homes, offices, workshops, and supervised facility routines.
Today
A living practice library
Learners now use checklists, comparison exercises, and documentation drills to form dependable habits.
Our mission
Make routine filter replacement easier to understand, easier to teach, and easier to document—without promising outcomes that depend on equipment, environment, or professional inspection.
