There is no "Only Solution. Improving air quality is achieved by emission reductions of many types, treatment, alternate fuel use, fuel reduction, dispersion of emitted gases, etc.

We can clean the air by planting trees!; not only planting but growing them also.!!!
air is a solution as it is homogeneous mixture of mostly nitrogen with some oxygen, some carbondioxdie, and lots of small amounts of other gasses including hydrogen and argon. "Clean" air usually refers to no dust, car exhaust or other particles/gases. But all air has nitrogen, oxygen and carbondioxinde - otherwise its not air. note solutions can be gases.
Air is the only gas-gas solution
The only reason to flush the ac system is if you had a compressor burn out. if this did not happen you just need to have the system recharged. you might have air the the system pull a vaccum on the system this should remove the air and the moisture. ******************************************************************* If you replace the compressor you should replace the drier and expansion valve and flush the system. To flush it you need a flush solution and clean dry compressed air. Put the solution in and force it out with the air one line at a time until the flush comes out clean. Install the new parts with the proper amount of oil and recharge the system.

Air is neither a colloïd solution nor suspension. It is quite the opposite: a homogeneous mixture, like ALL gases do: there is only ONE existent gas phase .
air is a solution
Only nitrogen, oxygen, argon and some minor natural components of air.
The only way to preserve clean air is to reduce the amount of air pollution. This is done by reducing emissions from human sources like vehicles, power plants, farms, and factories.
why is air considered a solution
5 GHZ only
