<p>Process, filter and device for eliminating from the air inhaled bacteria and/or viruses and/or fungi and/or spores and/or germs and/or allergens and/or contaminants and/or odors, etc, by means of a filter consisting of one or several layers of chemisorption mixture. In order to prevent the possible release of fungus spores and bacteria by biofilters in operation for a long time, it is proposed to use downstream of a biofilter layers of bulk material as chemisorption mixture layers alternately of a very strongly alkaline and very strongly acid nature or vice-versa. For the bulk material, use is made of coal coke of types III or IV of crushed coke with strongly alkaline and strongly acid chemisorption layers. The individual layers of chemisorption mixture are felt layers which are impregnated with alkaline, acid and/or neutral liquids or vice-versa, subsequently dried and superimposed in an alternating manner, being used as a chemisorption layer, hydrophobic separation layers being located between the chemisorption layers. In order to eliminate smells, said chemisorption layers consist of activated carbon treated with propylene glycol. Projecting from the inlet side of the air humidifier installation is a chemisorption filtering assembly which enables humidification of the air free from allergens and totally blocs the airborne allergens as well as the germs. After interruption of the unit by hand or by remote control, a bactericidal and fungicidal chemisorption filter also acts as a barrier on the discharge side.</p> |
