Material technology
for a cleaner future.

These four are the most representative MOF systems in MOFIL's R&D and production pipelines. For each industry's pollution spectrum, we use these frameworks as a parent, then engineer linker functionalisation, pore trimming and active-site modification into a customer-specific filtration media.

1. 01What is MOF (Metal-Organic Framework)?+

   An MOF is a class of periodic crystalline porous material formed by self-assembly of inorganic metal nodes and organic linkers via coordination bonds. Its surface area can reach 8 000 m²/g — more than ten times the surface area of equivalent-mass activated carbon. The pore size is tunable at the molecular level between 0.5 – 2 nm, and the active sites are dispersed at atomic resolution. This gives MOFs a combined geometric + chemical selectivity for gas-phase molecules.
2. 02How is MOF media different from activated carbon or molecular sieves?+

   Activated carbon relies on random pore structure and collision probability to capture pollutants — its selectivity is weak and its loading capacity is bounded. MOF pores, by contrast, are engineered crystallographically: size, shape and surface chemistry are all tunable, so the framework and linker chemistry can be customised for specific target molecules such as SO₂, NH₃ or toluene. Under the same weight and operating conditions, MOFIL's acid AMC media adsorbs SO₂ at 1.7× the level of mainstream imports; the base NH₃ media at 1.4×.
3. 03What is AMC, and why must cleanrooms control it?+

   AMC stands for Airborne Molecular Contamination — chemical pollutants present in air at the molecular level, primarily acidic gases (SO₂, H₂S), basic gases (NH₃) and volatile organic compounds (VOCs such as toluene, acetone, IPA). In advanced semiconductor processes, AMC damages electron mobility, raises leakage current, and shortens device lifetime — it is the invisible variable beyond particulates that determines yield. Chip, battery and pharma cleanrooms require AMC control at ppb / ppt levels.
4. 04How do I choose between MFT, MFV and MFX?+

   All three are built on the same MOF chemistry; the mechanical structure differs by deployment scenario. The MFT cylinder series carries a high media charge and can pack acid / base / VOC media in parallel inside one module — best for complex pollutant spectra. The MFV V-bank series has a large contact area and low pressure drop — best for high-airflow, long-cycle fresh-air and return-air systems. The MFX deep-pleat box series specialises in linker-level customisation — best for precise removal of a single target contaminant.

5. 05Which test standards is MOFIL's AMC media certified against?+

   MOFIL operates its own AMC filtration test centre. Performance is measured per GB/T 30190 ('Air Chemical Filter — Purification Efficiency and Pressure Drop Test Method') and ISO 10121-1 ('Test methods for assessing the performance of gas-phase air cleaning media and devices'). The publicly stated 1.7× / 1.4× comparisons, 93 / 97 pa resistance, 99.99 % initial efficiency, and 80 % cutoff efficiency all come from the same standardised pipeline. Customers may arrange third-party retesting or on-site witness testing.
6. 06Which industries does MOFIL serve?+

   Four core cleanroom environments today: semiconductor and microelectronics (panel, drive, advanced-node fab); new-energy battery (cathode, separator, electrolyte lines for lithium and solid-state cells); pharma and healthcare (pharmaceutical cleanrooms, ICU, OR, isolation wards); transit and mobility (fresh-air and cabin HVAC for airports, metro, high-speed rail, transit hubs). Adjacent deployments include biodefence, defence and aerospace, animal labs, and OLED panel plants.

* All performance numbers are measured at MOFIL's own AMC test centre using GB/T 30190 / ISO 10121-1 methods. Field suitability remains subject to on-site validation.
