The Magc-Alcan and Nirmal filter are examples of household filters that use activated alumina as the adsorption medium.
Filters based on passive and solar oxidation make use of naturally occurring dissolved Fe(OH)2 in the groundwater to remove arsenic. The Swiss research institute Eawag has developed developed filters based on the SORAS (Solar Oxidation and Removal of Arsenic) method.
