In OdorOff absorption washers the polluted air is led through a washer in which the undesired particles are captured in liquid. This method is applicable to larger quantities simply by adjusting the size of the washer. The end result can also be optimized by adding special odor binding liquids to the washer.
This method of odor removal is patented by OdorOff. The washer removes large quantities of odor compounds and the odor quantities can thus be reduced to the desired level. This method can also be used in removing other undesired particles such as dust. The washers produce a well-functioning and cost-effective method for odor removal. It can also be used simultaneously with other odor removal methods.
