Ask the plants. Carbon Dioxide in, a bit of messing about, and then oxygen out.

Do you know how fractional distillation works? A mixture of liquids can be separated (unless they form an azeotrope) by carefully heating them and allowing them to evaporate (and be condensed and collected) one at a time. This is how, for example, ethyl alcohol (with 5% water by volume) can be isolated from anything fermented.
Oxygen (and nitrogen, and argon) is obtained by the fractional distillation of liquid air. Unless there's a particular need for liquid oxygen, it isn't re-condensed, but otherwise the process is exactly similar to distilling whiskey. Of course, anything (like pollen or other dust) which doesn't evaporate is left behind.

combine 2 oxygen atoms and you get 1 pure oxygen atom
if you combine 3 oxygen atoms, you'll get 1 ozone atom
