Decreasing your mold exposure will require both the removal of mold and and moisture control to be effective. There are a number of things you can do to prevent mold growth in your home:
Wash, disinfect, and then dry all surfaces
Repair any leaks and dry moisture that results from leaks
Ventilate, preferably to the outside of your home, the source of any moisture such as clothes dryers, stoves and other appliances
Keep relative humidity less than 50% - this may require air conditioning or a dehumidifier
Keep drip pans from appliances such as refrigerators and air conditioners clean and dry
