High-Efficiency Particulate Absorption (HEPA) is an acronym for High-Efficiency Particulate Absorption. These filters are intended to catch particles as small as .03 microns. It will trap anything that is not water-soluble in the Sirena Vacuum. As a consequence, the filter’s life is extended.
The HEPA filter should be washed every 3-4 months and replaced every 12-18 months. HEPA filters are extremely helpful for those who have a variety of respiratory problems.
