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.

Yes. MeeFog systems are compatible with pharmaceutical, biotech, and semiconductor cleanrooms, where precise humidity control is essential for compliance, product safety, and process stability. By delivering energy-efficient humidification without steam boilers, MeeFog aligns with industry requirements for sustainability, reliability, and environmental control.

ROI is typically very fast due to energy savings and reduced maintenance costs. Facilities like Danfoss Power Electronics achieved payback in less than two years thanks to the tenfold reduction in energy use. In addition to financial savings, MeeFog systems improve reliability, lower operational risk, and provide cleaner humidification without the burden of gas-fired boilers.

MeeFog uses overhead fogging nozzles connected to a central high-pressure pump, operating at around 1,000 psi. This design ensures fine, evenly distributed droplets that evaporate quickly, maintaining stable humidity across the entire cleanroom or production floor. By avoiding localized steam injection, MeeFog prevents humidity hotspots or dry zones.

MeeFog offers dramatic energy savings in humidification compared to steam. In the Danfoss case study, annual humidification costs dropped from $8,000 in gas and electricity to just $750 in electricity with MeeFog. That’s more than a 90% reduction in energy costs—a savings factor of ten—while delivering superior performance.
