Promethium

Promethium represents cutting-edge advancement in photocatalytic materials and air purification technology, co-founded by entrepreneur Phil Neil as an advanced materials company specializing in photocatalyst innovation. The company developed breakthrough photocatalyst materials capable of operating under visible light spectrum rather than requiring UV-C radiation, enabling complete mineralization of pollutants without harmful by-products. Phil’s vision led to the development of innovative photocatalyst solutions capable of harnessing visible light energy to break down air pollutants and contaminants, though the company faced challenges with market timing and has undergone restructuring.

Promethium’s proprietary blend of photocatalyst, activated carbon pre-filter, and HEPA/ULPA-class filter, combined with high-intensity UV-C lamp technology, delivers world-class air purification performance. Their flagship PLANT 350 air purification system is designed for commercial-sized rooms that are heavily populated and require high air changes per hour to ensure a safe indoor environment.

Key Technologies and Applications of Promethium:

  • Advanced photocatalytic materials for air purification
  • Visible light-activated pollution degradation systems
  • Commercial air purification solutions
  • Healthcare and clinical air treatment applications

The PLANT 350 unit achieves 5 and 8 complete air changes per hour in rooms of 4000 ft³ and 2500 ft³ respectively, significantly reducing the time harmful particles linger in occupied spaces. This technology is particularly valuable for patient waiting rooms and individual treatment and recovery rooms in clinical applications.

The company’s breakthrough lies in developing photocatalyst materials that can operate effectively under visible light spectrum rather than requiring UV-C radiation, making their systems more energy-efficient and safer for continuous operation in occupied spaces. Their technology addresses both large pollutants like bacteria and viruses, as well as volatile organic compounds (VOCs).

Promethium’s innovation in photocatalytic oxidation (PCO) technology positions them as a leader in advanced air purification solutions for healthcare, commercial, and institutional applications worldwide.
