The market is projected to reach USD 1.19 billion by 2035, a CAGR of 8.59% from 2025. **How fast is the Data Center Air Filtration Market growing?** 8.59% a year from 2025 to 2035, after 10.56% a year from 2020 to 2025, because liquid cooling moves 75% to 85% of AI rack heat off the air path while the air-handled base still doubles to 231.0 GW. **What does data center air filtration include?** USD 520.20 million of 2025 spending on pre-filters, fine filters, HEPA and EPA filters, gas-phase (chemical) media and housings bought for data centers. Air handlers, water treatment, generator fuel filters and cleanroom fab filtration are excluded. **How much do data center air filters cost per MW?** USD 3,600 per MW of air-handled IT load a year for replacement filters and media in 2025, and USD 11,000 per new air-handled MW at first fit (DC Market Insights estimates). **What MERV rating do data centers need?** MERV 8 for recirculated room air and MERV 11 or, preferably, MERV 13 for outside air, according to ASHRAE TC 9.9 guidance, which keeps data halls at ISO 14644-1 Class 8 cleanliness. **Why do data centers use gas-phase filtration?** 300 angstroms a month of copper corrosion is the ASHRAE G1 limit (silver 200). Sites above it need chemical media because lead-free solder corrodes faster; gas-phase filtration grows 11.16% a year to USD 284.63 million by 2035. **Which filter type leads data center air filtration?** Fine filters (bag and rigid box), with 38.0% of 2025 value or USD 197.68 million. Gas-phase (chemical) filtration grows fastest, at 11.16% a year. **Which region leads the Data Center Air Filtration Market?** North America, with 39.0% of 2025 value or USD 202.87 million. The Middle East and Africa grows fastest, at 12.13% a year, as dust loads on Gulf campuses shorten filter life. **Who are the leading data center air filtration companies?** About 50% of 2025 value sits with the top five: Camfil, AAF International (Daikin Industries), Parker Hannifin (Filtration Group and Purafil), Freudenberg Filtration Technologies and MANN+HUMMEL (DC Market Insights assessment). **Why do Data Center Air Filtration Market estimates differ?** USD 589.74 million in 2026 is the DC Market Insights figure for filters, media and housings in data centers only. Estimates that add air handlers, cleanroom filtration or commercial HVAC filters are several times larger. ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 520.2 | USD million | | Revenue CAGR | 8.59 | % | | Market size 2035 | 1,185.94 | USD million | ## Frequently asked questions ### What is the size of the Data Center Air Filtration Market in 2026?
