SupaSpun II R31
DWI Regulation 31 requires that only filtration products approved by the Secretary of State can be used in the supply of drinking water.
To help water supply companies meet this legal requirement Amazon Filters have introduced SupaSpun II R31 filters which are specifically designed and qualified for use in the purification and supply of public water.
These high performance depth cartridges have a precision graded porosity that provides absolute ratings, high dirt holding capacity and excellent flow rates. They are available in a wide choice of removal ratings and therefore can be used in a range of applications from removal of Cryptosporidium oocysts to reduction of turbidity. Made with sustainable polypropylene derived from waste cooking oil and other vegetable oil residues.
