In a recent study of 180 homes in seven states, the University of Arizona found that mold was thriving on 88 percent of windowsills, 83 percent of refrigerator seals, under 82 percent of sinks and on 49 percent of shower grout.

Here are some tips from the Asthma Allergy Foundation of America for preventing mold buildup:

– Make sure your home is adequately ventilated.

– Keep humidity levels below 40 percent.

– Do not carpet bathrooms and basements.

– Clean hard surfaces regularly with mold-killing products.
