The magic bit:
The home air purifier design, currently in the prototype stage, features two cylindrical columns of the FOAM3R material. During operation, one column is used to purify the air, while the other ‘regenerates’ for reuse through heating, restoring the foam’s sorbent properties.
The process also removes collected pollutants and dead microbial debris captured in the air through heating, and recovers volatile components through cooling and condensation, which are collected as a liquid that is safe to pour away.
FOAM3R is created in a simple one-step manufacturing process and can be shaped into a variety of form factors. It can also be retro-fitted into existing technology and is more energy efficient than comparable carbon-granule based air purification systems.
Seems like an interesting filter process. Cheap to produce but a bit more expensive to operate than traditional air purification. Wonder if we’ll see heaters with this tech.
