At least one embodiment relates to an air purifying machine comprising at least one housing and a plurality of cores wherein each core is disposed in the housing. There is also at least one fan disposed in the housing. In addition, there is at least one pump disposed in the housing, wherein the pump is configured to circulate a fluid inside of the housing. The cores comprise at least two cores disposed inside of the housing comprising a first core and a second core, wherein the second core is disposed inside of said first core and wherein the second core is not concentric with the first core. The non-concentric nature of the cores creates a compression location at a point where the two cores are disposed closest to each other. This compression location creates a higher-pressure location for air flow around the cores. The different size of the openings for air to circulate between the cores creates air turbulence which results in greater interaction between the incoming air and the bioreactive fluid solution inside of the air purification system.
