Humidification for Cleanrooms
Humidity for Manufacturing & Research Cleanrooms
Microchip & Semiconductor
To preserve the integrity of the clean room envelope, positive pressure has to be maintained in the room at all times. To accomplish this, large amounts of outside air are required to off set the exhaust and room leakage. The large air flows must have tight temperature and humidity control, and doing so in a budget friendly way is important.
Benefits:
• Reduces electrostatic shock.
• Low energy consumption.
• Precise humidity level control.
• Ultra-fine droplets evaporate – no wetting.
Aerospace & Auto Paint Booths
MeeFog is able to provide humidity for large airflows with a single MeeFog system. Lower energy costs than a steam humidifier and low maintenance means the system can pay for itself in a matter of years. Proper humidity control can solve issues with fluctuations in moisture which may cause costly defects. Many spraying and bonding processes will benefit as dry air can cause premature drying.
Benefits:
• Maintain moisture content while curing.
• Reduce dust and static control problems.
• Enable product repeatability.
• Lessen down-time.
Pharmaceutical
Manufacturing pharmaceuticals requires a controlled environment. In cleanrooms, it is especially important to maintain a perfect relative humidity. The MeeFog system is integrated into the building management system and controls the building humidity levels perfectly. Return on investment in two years is common due to low maintenance and energy costs.
Features:
• Evenly distributed humidification.
• Increased reliability.
• Reduced energy costs.
• Improved product quality.
• Does not require compressed air or steam.

Reverse Osmosis Water Purification
Reverse Osmosis Water Purification
City water is treated using the Reverse Osmosis water treatment rack. This purifies the water, removing minerals, particulate, and microorganisms. Systems include automated membrane flushing, pre-treatment filtration, and UV Re-Circulation.
MeeFog Pump
MeeFog Pump
The high-pressure pump maintains 1000 psi water pressure in order to atomize the water into tiny droplets that can evaporate into the air stream. The pump rack has a VFD with panel-mounted controller that maintains pressure when staging valves open and close.
Staging Valves
Staging Valves
The valve panel allows precise control over how much humidification is injected into the air stream based on a signal from the BMS. It is possible to control the humidification level in the space to plus or minus 1% RH.
Nozzle Manifolds
Nozzle Manifolds
Fog nozzles are mounted on stainless steel tubing inside the air handler. These nozzles produce droplets in the 10-micron range. These precision nozzles are manufactured and tested in Mee Industries' own facility.
Mist Eliminator
Mist Eliminator
The mist eliminator removes water droplets larger than 5 microns. The filter pads can come off their stainless steel frames and can be washed or replaced easily.
System Overview
Nozzle Comparison
At an operating pressure of 2000 psi, the resulting average droplet size is roughly one tenth the diameter of a single strand of human hair.
MeeFog System Benefits
- Minimizes the risk of airborne infections.
- Decreases the occurrence of respiratory issues in newborns.
- Low energy consumption.
- Precise humidity level control.
- Elevates patient and staff overall comfort and virus protection.
- Lowers employee absence rate.
- Reduces premature drying and formation of scabs from coagulated blood.
- Prevention of electrostatic damage to medical equipment.
Droplet Comparison
Small droplets have a larger surface to volume ratio compared to larger droplets. This allows them to evaporate much more rapidly than larger droplets.

Cleanrooms FAQ
Cleanrooms and electronics production facilities must control humidity to prevent electrostatic discharge (ESD), which can damage sensitive components. Stable humidity also ensures compliance with ISO cleanroom standards, prevents contamination, and protects product quality. MeeFog systems deliver precise, reliable humidification ideal for these controlled environments. In the highly controlled environment of a clean room, temperature and humidity are kept to exact settings. Maintaining a precise +- 1% RH is possible with MeeFog and staging valves.
Traditional gas-fired steam systems consume excessive energy and often struggle to maintain even humidity. MeeFog’s centralized high-pressure fogging system uses no natural gas and maintains a consistent humidity level throughout the facility. At Danfoss Power Electronics in Illinois, one MeeFog system replaced an inefficient gas-fired system, eliminating humidity fluctuations while dramatically reducing energy use.
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.
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.
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.
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.
Featured Case Study
Army Research Laboratory Uses CHP and MeeFog Humidification to Cut Energy and O&M Costs
The Challenge:
The Army Research Laboratory in Adelphi, Maryland had been using a boiler to provide hot water as well as steam humidification to two clean rooms. It recently installed a combined heat and power system in its central utility plant, but the hot water generated was not hot enough to provide needed humidification.
The Solution:
A Meefog system was installed to provide humidification to both clean rooms, at a much lower cost and with less maintenance than the boiler.
