Get an air ionizer. You can find them around $ 30. on ebay or get one at a hardware store. Don't get one with an air filter as it is completely unnecessary and counterproductive as you will have to replace the filter.
It will take any crap out of the air quickly and give you a bit of an energy boost.
Also check the air filter if you have a forced air furnace. That is what was suspected as the source of Legionairs disease.
Another one that works really well but you may have a bit of trouble with finding the ingredients is to get one of those tea light diffusers

However the critical part is to put 6 drops of this :

In about a 1/2 to one cup of water in the diffuser. Light the candle or turn on the electricity if you have an electric diffuser or if you want low tech and easy just put a pot on a stove with a cup or two of water (amount doesn't matter at all) then put the drops of oil in. It will diffuse the aroma into the air and your coughing will stop.
I used to use it when we lived in a very dry place (!5% RH) for my daughters when they would cough. Took less than 5 minutes and the coughing stopped completely.
