Camfil provides filters that can remove molecules, gases and vapours from the air through molecular filtration. Our molecular products are tested according to ISO 10121 or ASHRAE 145.2.
Molecules are typically 1,000 to 10,000 times smaller than the most penetrating particles that pass through HEPA and ULPA filters.
All Camfil molecular filters utilise a technique known as adsorption. In simple terms this means sticking the molecules onto materials with extremely high surface areas. Nearly all Camfil molecular filters use activated carbon or activated alumina as the active ingredient. Molecular filters are also sometimes known as chemical filters or gas phase filters.
