FAQs

MeeFog systems help maintain the recommended 40–55% RH to protect books, paper, and bindings from drying, cracking, or degrading. At the same time, stable humidity reduces static buildup and supports better air quality, making libraries and archives healthier environments for staff and visitors.

Traditional steam humidifiers require large amounts of electricity or natural gas to boil water, driving up utility bills. MeeFog avoids boiling water entirely, instead using adiabatic fog humidification. On average, MeeFog uses 1/10th the energy of steam systems, making it the more sustainable choice for universities and schools focused on energy efficiency and environmental responsibility.

Hach Hall, the first LEED Gold-certified chemistry building in the U.S., needed an efficient way to humidify labs served by 100% outside air. MeeFog was chosen because it improved indoor air quality in winter, cut energy costs, and integrated seamlessly with Johnson Controls Metasys automation. The system cost $107,000 annually, saving $30,000 compared to a gas boiler system, while also ensuring 100% availability with a backup pump.

MeeFog systems consume a fraction of the energy required by steam humidifiers. Instead of using electricity or gas to boil water, MeeFog relies on a small high-pressure pump and a low-grade heat source (like a hot water loop) to create fine fog droplets that evaporate efficiently. This design allows schools and universities to cut energy costs by 50–80%compared to steam systems while meeting indoor air quality requirements.

Universities and libraries include diverse environments such as classrooms, lecture halls, study areas, and archives—each of which benefits from stable humidity. Stable humidity in educational environments helps maintain comfort, concentration, and health for students and staff. Low humidity can increase virus transmission, cause discomfort and fatigue, and damage books, paper, and archives. The recommended relative humidity (RH) range is 40–55%, which supports both wellness and preservation of valuable collections.

Most facilities see payback within 1–3 years due to energy savings, reduced maintenance, and elimination of steam boilers. The NC Museum of Art’s installation not only delivered measurable savings but also simplified their HVAC system, proving that MeeFog provides both financial and operational ROI.

Yes. MeeFog humidification systems are designed to achieve precise environmental conditions required for sensitive spaces such as museums, libraries, and galleries. The NC Museum of Art successfully reached ASHRAE Class AA compliance with a MeeFog system, which allowed them to host national traveling art exhibits without risk of humidity-related damage.

By replacing steam humidifiers with fog technology, MeeFog improves indoor air quality and ensures consistent humidity levels across large, open spaces. Visitors experience fewer comfort issues like dry air, while collections and building materials are better protected. The system also requires less maintenance, which reduces downtime and operational disruptions in public venues.

Traditional steam humidifiers require natural gas or electricity to boil water, leading to high operating costs. In contrast, MeeFog systems use a high-pressure pump and fine water atomization, cutting energy use by up to 90%. At the NC Museum of Art, this translated into more than $30,000 in annual savings, plus reduced carbon emissions.
