Why High-Pressure Water Mist Is Gaining Popularity in Fire Suppression
As businesses and facility owners navigate the changing landscape of fire suppression regulations, high-pressure water mist fire suppression systems are emerging as a leading alternative to traditional clean agent and inert gas systems.
With increasing environmental concerns over PFAS-based chemicals, regulatory shifts under the AIM Act, and the push for LEED and ESG compliance, organizations are prioritizing eco-friendly, sustainable, and effective fire protection solutions. High-pressure water mist (HPWM) technology is proving to be a viable alternative to chemical-based suppression, offering minimal water usage, zero harmful emissions, and unmatched fire suppression efficiency.
At Premier Fire & Security, we’re at the forefront of helping businesses adapt to these changes. In this blog, we’ll explore the growing demand for high-pressure water mist suppression, its advantages over traditional fire suppression systems, and how current regulations and sustainability initiatives are shaping its future in the United States.
What Is High-Pressure Water Mist Fire Suppression?
High-pressure water mist systems use ultra-fine water droplets to rapidly cool, displace oxygen, and suppress fires without the need for chemicals or large volumes of water. These droplets, typically smaller than 200 microns, create a cooling effect that interrupts the fire triangle (heat, oxygen, and fuel), stopping fires quickly and efficiently.
Key Benefits of High-Pressure Water Mist Systems
✔ Minimal water usage – Uses up to 90% less water than traditional sprinkler systems.
✔ No chemical agents – Eliminates concerns related to PFAS and HFC-based clean agents.
✔ Safe for people and the environment – No toxic byproducts, safe for occupied spaces.
✔ Rapid cooling effect – Reduces damage to property and assets.
✔ Suitable for sensitive environments – Protects data centers, archives, and medical facilities without water damage.
Why Are Businesses Moving Toward High-Pressure Water Mist?
1. AIM Act & the Phase-Out of HFC-Based Clean Agents
What’s Happening?
- The American Innovation and Manufacturing (AIM) Act is phasing down the production and import of hydrofluorocarbons (HFCs), including FM-200® and other synthetic fire suppression agents.
- By 2024, HFC availability will be reduced by 40%, with an 85% reduction by 2036.
- This phase-out is driving up the cost of FM-200® and other HFC-based fire suppression systems, making alternatives like water mist and inert gas suppression more attractive.
Why It Matters:
✔ High-pressure water mist is not affected by AIM Act regulations, making it a future-proof investment.
✔ Water mist systems offer similar fire suppression effectiveness without the regulatory risks associated with HFCs.
✔ Facilities looking to avoid future price hikes and shortages of clean agents are transitioning to water mist suppression now.
2. The PFAS Controversy and Its Impact on Fire Suppression Choices
What’s Happening?
- The EPA, state governments, and international regulators are tightening restrictions on PFAS-based chemicals due to environmental and health concerns.
- Fire suppression agents like Novec™ 1230 contain fluorinated compounds, making them subject to potential bans.
- 3M has announced it will stop producing Novec™ 1230 by 2025, creating uncertainty around the long-term availability of PFAS-based suppression agents.
Why It Matters:
✔ High-pressure water mist is 100% PFAS-free, eliminating concerns over future bans.
✔ Unlike clean agent systems, water mist requires no chemical recharge or special disposal considerations.
✔ Facilities investing in PFAS-free solutions now will avoid potential compliance issues down the road.
3. Green Building, LEED, and ESG Sustainability Initiatives
What’s Happening?
- Companies are adopting LEED certification and ESG (Environmental, Social, and Governance) standards to meet sustainability goals.
- LEED and ESG initiatives prioritize low-impact, water-efficient, and chemical-free solutions in building infrastructure.
- NGOs and environmental advocacy groups are pressuring businesses to transition away from HFCs, PFAS-based agents, and high-water-use systems.
Why It Matters:
✔ High-pressure water mist is LEED-friendly, helping businesses earn sustainability credits.
✔ Water mist systems reduce water waste, making them attractive for eco-conscious businesses.
✔ Companies prioritizing ESG reporting and sustainable infrastructure are choosing water mist over chemical agents.
What Are the Best Applications for High-Pressure Water Mist?
Water mist fire suppression is ideal for:
| Facility Type | Why It’s a Great Fit |
| Data Centers & IT Rooms | No chemical residue, safe for electronics |
| Healthcare & Laboratories | Non-toxic, safe for sensitive environments |
| Museums & Archives | Protects artifacts from water damage |
| Industrial Plants | Reduces fire risk in machinery-heavy spaces |
| Hotels & Commercial Buildings | LEED-compliant, sustainable solution |
| Oil & Gas Facilities | Effective for high-risk environments |
How Does Water Mist Compare to Other Fire Suppression Systems?
| Feature | High-Pressure Water Mist | Inert Gas (IG-55, IG-541) | Clean Agents (FM-200®, Novec™ 1230) |
| Environmental Impact | Low water use, no chemicals | No GWP, natural gases | PFAS & HFC concerns |
| Regulatory Risk | No restrictions | PFAS-free, stable | AIM Act & PFAS bans |
| Effectiveness | Cools & displaces oxygen | Oxygen displacement | Chemical reaction-based |
| Residue & Cleanup | No residue | No residue | Potential chemical breakdown |
| Long-Term Viability | Future-proof | Long-term option | Supply chain uncertainty |
What Should Facility Managers Do Now?
With AIM Act restrictions, PFAS bans, and green building standards reshaping the fire suppression industry, businesses should take proactive steps to future-proof their fire protection strategy.
✔ Assess Your Current Fire Suppression System
