Our farming is affected due to poor rain and less water, These lands are now used to produce salt. This is because of the co2 from big factories and vehicles. The Co2 from vehicles are sources are the major reason breathing problems for many people in cities who needs medication. These vehicles and factories should use the proper filter with water to create oxygen. This will avoid the climate change and help people.

• First part is the oil-filter.
• Second part is the nice cotton cloth which acts as a filter for the oil and the hot air.
• The third part is the water-filter set up.

FIRST PART

When the acid and oil- mixed hot air comes out from the silencer ,enters into the first part of the filter loses its acidity.

SECOND PART

When the acid and oil- mixed hot air comes out from the first part, and enters into the second part of the filter, it further reduces its acidity and it purifies the moist oily air passes from the cotton cloth , it absorbs the moist oil and air and hence it is purified at the second part .

THIRD PART

When the hot air (with carbon -di- oxide )comes out from the second part goes to the third part which is a water-filter which consists of a cold water pot further reduces the residuals and finally the output from the silencer is completely purified and goes out from the outlet of the filter as a cool domestic pure air.

Thus the outlet from the silencer is purified and comes out as an oxygen content air.

When this set-up is fixed in the automobiles, factories ,home appliances such as refrigerators ,industries, in high- speed generators etc., and in all pollution-giving equipments we can avoid the global warming by controlling the chlorofluorocarbon content in the atmosphere.
