Pollution in farms decreases the productivity and health of livestock due to feed, excrement, and other waste. The main pollutants include CO2, ammonia, hydrogen sulfide, CO, and dust. To clean the air on farms, PUROH has developed Cyclohnic, a contaminant air purifier that inactivates a large proportion of pathogenic microorganisms and mineralizes pollutant gases and particles. There are two Cyclohnic models according to the air filtration quality. Incorporating this technology reduces veterinary care, the use of medications, and increases livestock productivity, preventing the possibility of massive contagion.
