The market is projected to reach USD 180.33 million by 2035, a CAGR of 5.02% from 2025. **How fast is the Data Center Humidifier Market growing?** 5.02% a year from 2025 to 2035, after 5.35% a year from 2020 to 2025, because replacement and service on a 36,895 MW humidified installed base grow faster than new halls that need humidifiers. **What does a data center humidifier do?** USD 110.51 million was spent in 2025 on units that add moisture to data hall air so it stays above the ASHRAE minimum of −9°C dew point recommended (8% relative humidity allowable), limiting static discharge risk for IT equipment. **Which type of data center humidifier leads the market?** Electrode and resistive steam humidifiers lead with 45.0% of 2025 value (USD 49.73 million). Ultrasonic humidifiers grow fastest at 8.28% a year, and high-pressure atomising units become the largest type by 2035 at USD 72.13 million. **How much does a data center humidifier cost per MW?** About USD 12,000 per humidified MW of IT load in 2025, including installation, controls and water treatment, plus about USD 1,200 per MW a year for service and consumables (DC Market Insights estimates). **Do AI data centers need humidifiers?** Only about 5% of new AI capacity was humidified in 2025, against 30% of new conventional capacity, because liquid-cooled AI halls move little outdoor air; AI adds under USD 1.1 million a year of new-build humidifier spend. **Which region leads the Data Center Humidifier Market?** North America leads with USD 44.20 million, 40.0% of 2025 value. The Middle East and Africa grows fastest at 7.80% a year, and India is the fastest large country at 12.26% a year. **What rules apply to data centre humidifiers in London?** USD 5.75 million was spent on UK data centre humidifiers in 2025, about 70% in London and Slough. Each unit falls under HSE Approved Code of Practice L8 and HSG274 Part 3: risk assessment, cleaning, monitoring and records. **Who are the leading data center humidifier companies?** Condair Group leads with about 28% of 2025 value (DC Market Insights assessment), followed by Carel Industries, DriSteem, Armstrong International and Vertiv; the top five hold about 60%. **Why do Data Center Humidifier Market estimates differ?** DC Market Insights values the market at USD 119.05 million in 2026 because it counts only humidifiers used for humidity control; broader estimates add evaporative cooling media, adiabatic pre-coolers and whole cooling units, which are cooling equipment. **How do data center humidifiers fit in the industrial humidifier market?** USD 110.51 million of 2025 humidifier spend went to data halls, one buyer group in the wider industrial humidifier market alongside cleanrooms, printing, textiles and food storage; DC Market Insights counts only data center purchases. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 110.51 | USD million | | Revenue CAGR | 5.02 | % | | Market size 2035 | 180.33 | USD million | ## Frequently asked questions ### What is the size of the Data Center Humidifier Market in 2026?
