Air purifier

Abstract

An air purifier includes a housing (1), an intake built into the housing (1) which is designed for the intake of air into the housing (1), an exhaust built into the housing (1) which is designed for the venting of air out of the housing (1), a blower (2) disposed in the housing for generating an air stream which flows from the intake to the exhaust, at least one filter (3) which is designed to purify the air flowing from the intake to the exhaust, and a bioreactor (4) which is disposed on and/or in the housing (1) such that the air stream flows through it, and which contains at least one life form (5) which is designed to at least partially convert CO2 contained in the air stream into O2 by means of photosynthesis.

1 . An air purifier comprising:
 a housing ( 1 ),   an intake built into the housing ( 1 ) and configured for an intake of air into the housing ( 1 ),   an exhaust built into the housing ( 1 ) and configured for venting of air out of the housing ( 1 ),   a blower ( 2 ) disposed in the housing for generating an air stream which flows from the intake to the exhaust,   a filter ( 3 ) configured to purify the air flowing from the intake to the exhaust, the filter including a bioreactor ( 4 ) disposed on or in the housing ( 1 ) such that the air stream flows through it, and containing at least one photosynthesizing life form ( 5 ) configured to at least partially convert CO2 contained in the air stream into O2 by photosynthesis.   
     
     
         2 . The air purifier according to  claim 1 , wherein the at least one photosynthesizing life form ( 5 ) is at least one alga. 
     
     
         3 . The air purifier according to  claim 1 , wherein the at least one photosynthesizing life form ( 5 ) is contained in the bioreactor ( 4 ) as a suspension culture. 
     
     
         4 . The air purifier according to  claim 1 , wherein the bioreactor is composed of multi-skin sheets with at least one membrane module, through which the air stream flows. 
     
     
         5 . The air purifier according to  claim 1 , further comprising a lighting unit ( 6 ). 
     
     
         6 . The air purifier according to  claim 5 , wherein the lighting unit ( 6 ) comprises light-emitting diodes. 
     
     
         7 . The air purifier according to  claim 5 , wherein the lighting unit is designed to emit wavelengths in the range of red light. 
     
     
         8 . The air purifier according to  claim 1 , further comprising a WLAN module ( 7 ). 
     
     
         9 . The air purifier according to  claim 1 , further comprising by a humidifier ( 8 ) or a moisture sensor. 
     
     
         10 . The air purifier according to  claim 1 , further comprising a temperature sensor. 
     
     
         11 . The air purifier according to  claim 2 , wherein the alga is a microalga.
