Dry Fog technology is what sets Pure Maintenance apart from the competition. Instead of sledgehammers and axes slamming into your mold-infested walls, tiny particles of a dry fog fill the capacity of your home or office, destroying all mold cells in its path. Our patented micron particle is so small that it continues to bounce around the room for several minutes before finally dissipating. The best part about developing such a particle is that it gets nothing in your home or office wet.
