Dry Fog technology is what sets Pure Maintenance apart from the competition. Instead of sledge hammers 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 and pathogen cells in its path. Our patented Dry Fog 0.75 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.
