FAQs

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.

MeeFog systems can consolidate dozens of distributed steam humidifiers into a single central system. For example, at the North Carolina Museum of Art, one MeeFog system replaced 92 steam humidifiers, eliminating the need for a boiler system dedicated to steam. This streamlined the HVAC design, simplified maintenance, and reduced energy costs dramatically.

Public spaces with sensitive collections, art, large crowds, or valuable assets that are highly vulnerable to environmental fluctuations, require precise humidity control. Without it, facilities experience wide humidity swings that can damage artwork, artifacts, furnishings, and even affect visitor comfort. Low humidity causes materials like paper, canvas, wood, and textiles to become brittle, crack, or fade. Controlled humidification—typically between 45–55% RH—is crucial for preserving cultural and historical assets over time. MeeFog systems help facilities meet strict standards like ASHRAE Class AA conditions, ensuring stable environments for both people and property.
