Abstract
Smoke filters that reduce the concentration of carbon monoxide and phenols in a smoke stream may include a porous mass section comprising a plurality of active particles, a plurality of binder particles, and an active coating disposed on at least a portion of the active particles and the binder particles, wherein the active particles and the binder particles are bound together at a plurality of contact points; and a filter section. In some instances, a filter may include a porous mass section comprising a plurality of active particles and a plurality of binder particles, wherein the active particles and the binder particles are bound together at a plurality of contact points without an adhesive; and a filter section comprising an active dopant.
Claims16
A porous mass comprising:
- a plurality of active particles and a plurality of binder particles, wherein the active particles and the binder particles are bound together at a plurality of contact points, wherein the active particles comprise phosphorous pentoxide.
A porous mass comprising:
- a plurality of active particles, a plurality of binder particles, and an active coating disposed on at least a portion of the active particles and the binder particles, wherein the active particles and the binder particles are bound together at a plurality of contact points, wherein the active coating comprises triacetin, triethyl citrate, acetyl triethyl citrate, tributyl citrate acetyl tributyl citrate, acetyl tri-2-ethylhexyl, POE (4) lauryl ether, POE 20 sorbitan monolaurate, POE (4) sorbitan monolaurate, POE (6) sorbitol, POE (20) C16, and any combination thereof.
A filter comprising:
- a porous mass section comprising a plurality of active particles and a plurality of binder particles, wherein the active particles and the binder particles are bound together at a plurality of contact points without an adhesive, wherein the active particles comprise phosphorous pentoxide;
- and
- a filter section comprising an active dopant.
