What is not a characteristic of a cyclone air cleaner?

The characteristic that is not associated with a cyclone air cleaner is its ability to remove all dusts of health importance. Cyclone air cleaners are designed to capture and filter out larger dust particles and aerosols effectively, primarily using the force of centrifugal action. However, they may not be able to remove all fine particles, especially those that can be of significant health concern, such as smaller particulate matter or certain types of toxic dust.

While cyclone air cleaners can significantly reduce the concentration of airborne dust, it's important to note that some harmful particles may still pass through these systems. The effectiveness of any air filtration system is often dependent on the specific design and the size of the particles involved.

The other characteristics described are accurate: these air cleaners are indeed effective at filtering a variety of dust particles, they typically require regular maintenance to ensure optimal performance, and they operate based on the principles of centrifugal force to separate particles from the air stream.
