PURPOSE:To improve sanitary and comfortable properties by a construction wherein a second filter composed of a charged net and an activated charcoal net is fitted rollably in the rear of a net filter in an air filter device for an air- conditioner. CONSTITUTION:Very minute dust passing through the net 9 of a first filter 7 is attracted by a charged net 11 of a second filter 10 to be removed. Moreover, a smell in air is adsorbed by an activated charcoal net 12 to be deodorized. Thus, purified and refreshed air is supplied into a room. A filter 6 having turned ineffective is rolled up by the rotation of a roll 13, and a new filter is set instead. By this constitution, sanitary and comfortable properties can be attained. |
