| ADSORBENT | WHAT IT ADSORBS |
| Carbon | Removes xylene and most common paint solvents. Ineffective at removing methanol. |
| Zeolite w/ 6A pores | Removes methylene chloride, methanol and most low molecular weight solvents. |
| Zeolite w/ 8A pores | Removes higher molecular weight solvents. |
| Carbon & zeolite in series | Removes solvent mixtures containing moderate amounts of methanol (15% to 25%) at low total concentrations (<250 ppm). Note: A physical mixture of carbon and zeolite on a single substrate is more effective than the two in series in removing high concentrations of solvents (>300 ppm) with lower alcohol contents. |
