The Solenco CF8500 comes with a 3-in-1 filter consisting of a pre filter, HEPA filter and a carbon filter.
The Pre-filter removes the large airborne particles
The true HEPA filter removes particles from the air as small as 0.3 microns – smaller than the eye can see.
The Carbon filter removes smells and odours.
The enhanced charcoal and HEPA filters have a rubber gasket seal to ensure that no air leaves the air purifier uncleaned.
The unit has a replace filter indicator light.
