Air Cleaner Power Tool FAQ

How do I choose the right size air cleaner for my workshop?

To select the correct unit, calculate your shop's total volume (length x width x height) and multiply by the desired air changes per hour, typically 6 to 8. Choose an air cleaner with a CFM (Cubic Feet per Minute) rating that meets or exceeds this calculation to ensure efficient filtration.

What is the difference between a shop vacuum and an ambient air cleaner?

A shop vacuum or dust extractor is designed for source collection, capturing large chips directly from the tool. An ambient air cleaner is designed to filter the fine, airborne "invisible" dust particles that escape the vacuum and remain suspended in the air throughout the room.

Where is the best location to mount an air cleaner?

For optimal circulation, mount the unit at least one-third of the way along the longest wall, roughly 7 to 8 feet above the floor. Avoid placing it in a corner; instead, position it so the intake and exhaust create a circular airflow pattern (the "Coanda effect") throughout the workspace.

How often should I replace the filters in my air cleaner?

Inner filters should generally be replaced every 6 to 12 months, while outer pre-filters should be cleaned or replaced every 1 to 3 months depending on usage. Many modern units feature a pressure sensor or indicator light that signals when airflow is restricted and maintenance is required.

What does the "micron rating" mean for air cleaner filters?

The micron rating indicates the size of particles the filter can trap. Most woodworkers should look for a primary filter rated for 5 microns and a secondary/inner filter rated for 1 micron. This ensures that the smallest, most harmful respiratory dust is effectively removed from the breathing zone.
