  • FAQ

    Q: Can the virus be removed with a HEPA filter?

    A: A high-performance filter that collects 99.97% or more of particles with a rated air volume and a particle size of 0.3 micromillimeter. It is set to collect mainly 0.3 micrometers, which is considered to be the most difficult to collect particles (poor collection rate), and the mechanism of particle streamline obstruction, collision, electrodeposition, diffusion, etc. by the fibers that make up the filter. The air is filtered, and the collection performance is fully exhibited even at 0.3 micrometer or less.

    Q: Isn't the inside of the box stuffy?

    A: The inside of the box is not sealed because air enters through the gap of the cover and the air supply filter even when the exhaust unit is not connected. In addition, when the exhaust unit is in operation, air enters through the air supply filter and is discharged from the duct through the breathing area of ​​the subject, so there is no suffocation.
