The filter in your air conditioner or central heat and air conditioner helps to keep dust and other particles out of the air. It also keeps dust and other particles from entering the mechanical parts of your system. Window unit air conditioners and heaters usually have a washable filter and central heat and air units usually have a disposable one.
For the window unit filters it is recommended that you clean the filter after every 120 to 320 hours of use. That is about one to two weeks of use. Certain conditions may require cleaning more often. Usually you can use a shop vac to clean the bulk of the dust out of the filter. Then you can gently spray out the rest with either a shower head or spayer head at your sink. Allow the filter to dry and then replace it.
Central heat and air units generally use a disposable filter, but there is a trend toward washable filters for that as well. It is recommended by most manufacturers that you replace your filter every two weeks to month. you can prolong the life slightly by vacuuming out the filter once a week or so. This is almost necessary if you happen to have pets. Otherwise just throw the filters away and put in a new one. The filters are usually sold in packs of two or three.
Changing the filters not only help to keep your air free of particles that could cause allergies it can also keep your air conditioner or central heat and air unit from needing costly repairs. If a unit is going to break down it is going to be when you most need it. Keep those filters clean and save money while doing it.
