Fpollution testing before entering offices and homes through air conditioning units can prevent the entry of 99% of chimneys, scientists concluded.
The University of Nottingham Trent and the Chinese Academy of Sciences are trying to find a way to prevent the deadly pollution of external air from entering prison.
They found that if the pollution is frozen to about -18C in the condensation tube, the particles meld together and fall to the bottom, allowing the passage of fresh, clean air.
Their method was able to remove 99 percent of the particles and 98 percent of pollutants of nitrogen oxide. We hope that work will be able to open the way for simple modification of air conditioners and humidifiers …
