Mof-fabric filtration technology for air purification

Overview

Hava Technologies has developed a novel process for rapidly applying metal-organic frameworks (MOFs) onto fabrics, creating a multifunctional filtration material capable of removing particulates, chemicals, odors, volatile organic compounds (VOCs), and pathogens from air. MOFs are highly crystalline, porous materials formed by linking metal ion clusters with organic ligands. When applied to fabrics, they create filters that use electrostatic surface potential to attract and capture particles while the porous structure adsorbs small molecules and chemicals. The technology has demonstrated up to 90% particle filtration efficiency and offers a reusable, washable solution for air purification.

Technical specifications

Key features:

• Rapid MOF application process enables coating of fabrics with minimal pressure drop
• Electrostatic surface potential captures particulate matter and limits penetration through the membrane
• Porous MOF structure adsorbs small molecules, chemicals, and odor-causing compounds
• Antibacterial capabilities through MOF loading of antibiotic molecules
• Multiple MOFs can be loaded onto a single fabric for multifunctional performance
• UiO-66 MOF demonstrated loading capacity of 10 wt% for small molecules such as methylene blue
• NU-901 MOF shown to load peptides, indicating capacity for antibiotic substances
• Compatible with roll-to-roll coating processes for large-scale fabric treatment
• Washable and reusable after particle and toxin removal

Technology readiness level

The technology has been validated through peer-reviewed publications and filed patents, with supporting data on filtration performance and MOF-fabric composites. Current efforts focus on creating multifunctional MOF fabrics for HEPA filter applications, scaling production through roll-to-roll coating processes, and confirming reusability after washing. The team is advancing toward integration with air circulation systems for whole-room air treatment.
