Fine filters

Fine filters are the most common type of filter in air cleaning. Fine filtration removes small particles that you cannot see by eye. In practice, the filtration is level EN16890 ePM1≥50%. The fine filter can be the only filter solution on the device, or it can be a part of the filtration chain of a more versatile device, starting from coarse filtration and ending in EPA/HEPA filtration after the fine filtration.
