The Differences Between Low VOC and No VOC Paints Paints With Low VOC Levels. Low VOC paints are often advertised as low odor, and their labels are clearly marked with VOC gram-level per liter. Paints with low VOC levels tend to be more expensive than regular paints. Moreover, they tend to not have the same coverage ability as regular paints, which means more coats need to be applied. Paint technology continues to improve, however, and some low VOC paints claim to offer coverage equal to regular paint.
