| titleOfInvention | Air purification filter device |
| abstract | (57) [Summary] The air purification filter device 1 includes a housing 3 having an air inlet 5 and an air outlet 7. An air transfer means 9 is provided for generating an airflow in the direction D from the inlet 5 to the outlet 7 through the filter element 11. The filter element 11 comprises at least one filter element formed of an absorbent fibrous material soaked in an acidic or basic aqueous solution. In a specific embodiment, the filter element comprises two filter units 13 and 15 arranged in series, wherein the filter unit 13 comprises a material impregnated with an acidic aqueous solution, and the filter unit 15 comprises a base. It is made of a material in which a neutral aqueous solution is immersed. If desired, at least one filter unit may contain at least one organic amine compound (e.g., 3-hydroxy) selected from the group consisting of alkali metal wetting agents (e.g., potassium formate) and / or urea and alkanolamines. Methylaminomethane). Also, a pH display function can be incorporated in at least one filter. |
