DESC: Amaircare air cleaners are individually tested to meet HEPA standards and beyond. This means that the complete air cleaner system will remove at least 99.97% of all particles as small as 0.3 microns (1/300th the size of a human hair or 0.000012 of an inch) that enter the air cleaner and are also 95% efficient at 0.1 microns. The 6000v is built to provide air filtration for large commercial spaces.
