Samsung patents filter that traps PFAS chemicals using heat control
Samsung has filed a patent for a vertical filter designed to capture PFAS, a group of chemicals often called 'forever chemicals.' The device uses a membrane to trap these substances and includes a heating element to adjust the filter's temperature for better performance.
In the filing’s own words
A per- and polyfluoroalkyl substances (PFAS) capturing filter including a first body extending in a vertical direction; a first cage surrounding a side surface of the first body, a membrane filter surrounding the first cage and configured to adsorb PFAS, a second cage horizontally spaced apart from the membrane filter by a predetermined distance, surrounding the membrane filter in a lateral direction, and including a protrusion bent at a lower side, a thermoelectric element surrounding the second cage and configured to control the temperature of the membrane filter.
What exactly they claim (claim 1)
1. A per- and polyfluoroalkyl substances (PFAS) capturing filter comprising: a first body extending in a vertical direction; a first cage surrounding a side of the first body; a membrane filter surrounding the first cage and configured to adsorb PFAS; a second cage horizontally spaced apart from the membrane filter by a predetermined distance, surrounding the membrane filter in a lateral direction, and including a bent protrusion bent on a lower side; and a thermoelectric element surrounding the second cage and configured to control a temperature of the membrane filter.
