Disposable gloves between 2 and 3.9 mils are generally used for light to medium duty tasks. They're popular for food prep, cleaning, manufacturing and packaging operations. Gloves under 3 mils should generally be used for your lighter tasks like chopping veggies. Once you get above 3 mils you're looking at gloves that can be used for heavier cleaning and cooking tasks. As well you'll start to see exam gloves in the 3+ mil range that are good for hospitals, nursing homes, home-care and medical centers.
