The chemical media undergoes 100% particle screening and homogenization (most products on the market suffer from uneven particle size, leading to unstable air resistance).
Multiple chemical adsorbent formulations (KMnO₄, activated alumina, impregnated activated carbon, etc.) are used to achieve composite adsorption, rather than a single material.
The iodine value, specific surface area, and loading rate of the media are all tested, while few products on the market have a complete media quality traceability system.
Each filter undergoes actual testing for air resistance, filling volume, uniformity, and adsorption capacity for chlorine/acidic gases, ensuring real performance rather than theoretical values.
Gas concentration simulation experiments are supported, and precise solutions can be provided based on on-site measurement data for SO₂, NOx, H₂S, ammonia, and VOCs.
SYNRUI is not only a manufacturer but also a supplier of air chemical purification solutions, providing standardized and customizable system-level outputs for different pollutants, truly achieving one-stop delivery from needs diagnosis → media selection → filter box design → performance testing → installation guidance.
Function of Chemical Air Filters
Chemical air filters are a type of molecular-level purification device based on chemical adsorption, oxidation-reduction, neutralization reactions, or physical adsorption. Their core function is to remove H₂S, SO₂, NO, NO₂, ammonia, alkaline gases, acidic corrosive gases, toluene, aromatic hydrocarbons, odorous gases, and molecular-level pollutants from the air. They are used in industries requiring high cleanliness, high equipment stability, and non-corrosive environments.
Product Advantages
Enhanced Chemical Adsorption Capacity: SYNRUI utilizes highly active KMnO₄ series adsorbents with impregnated adsorption media, boasting a specific surface area of 6,000–12,000 m²/g. Adsorption efficiency and oxidation capacity are 45%–120% higher than ordinary activated carbon.
Longer Lifespan: Controllable particle size distribution (2–4 mm), and multiple tests and calibrations of packing density and porosity ensure stable media saturation rates and prevent sudden failures.
Stable Air Resistance: Automated, uniform filling equipment avoids uneven packing; the frame is constructed of stainless steel or corrosion-resistant plastic, preventing deformation and leakage.
Supports Multi-Stage Filtration Combinations: It can be combined with a Pre-Filter + HEPA Filter + Chemical Filter purification chain design to improve overall efficiency and extend the lifespan of upstream filters.
Capable of Handling Complex Gases: Single adsorbents often cannot handle complex industrial environments. SYNRUI can combine multiple chemical media based on on-site testing data to enhance overall purification capabilities.
Quality Traceability: Each chemical medium has complete iodine value, specific surface area, pore size distribution, KMnO₄ loading rate, SO₂/NOx/H₂S ratio, and SO₂/NOx/H₂S ratio.
OEM/ODM: Supports customized structures, customized medium formulations, and customized module sizes to meet the needs of different equipment manufacturers and engineering companies.
- Semiconductor Factories: Removes AMC (Airborne Molecular Contaminants).
- Lithium-ion Battery Factories: Treats VOCs and acidic vapors.
- Laboratories and Biopharmaceuticals: Protects instrument precision and experimental accuracy.
- Food Production: Removes odors and volatile residues.
- Data Centers: Protects against corrosive gases and extends equipment lifespan.
- Petrochemicals: Neutralizes acidic and sulfurous contaminants.
- Art Galleries/Libraries: Protects artifacts, paper, and paintings from chemical corrosion.
- Cleanroom Systems: Serves as a core component of molecular-level end-of-line filtration.
1. Media Pretreatment Process: Drying, homogenization, and sieving ensure consistent particle size, improving ventilation efficiency and adsorption stability.
2. Optimized Porous Structure Filling Technology: Utilizing an automated quantitative filling system, the porosity error of each filling zone is controlled within ±3%, ensuring stable air resistance.
3. Frame Welding and Sealing Process: Stainless steel frames are automatically and uniformly welded, and plastic frames are fully molded, ensuring long-term non-deformation under high humidity/corrosive environments.
4. Leak Detection and Air Resistance Testing: Each unit undergoes air resistance and filling density testing to ensure no empty boxes or leaks.
Performance Verification: Testing can be performed upon request for SO₂ removal capacity, ammonia removal capacity, VOC removal efficiency, and high humidity environment attenuation rate, with curve reports provided.

A: We will recommend a suitable formula based on the on-site gas detection report, production process, and temperature and humidity environment provided by the client, and provide simulation experimental data.
Q: 3. What makes your chemical medium different?
A: Our medium undergoes screening and homogenization, resulting in controllable specific surface area and loading rate. Its adsorption capacity is over 45% higher than ordinary activated carbon.
Q: 4. What is the lifespan of your chemical filter?
A: It depends on the pollutant concentration, temperature, humidity, and airflow, generally 6–18 months. We can provide a predicted lifespan model under operating conditions.
Q: 5. Do you support customized sizes?
A: We support customization of all parameters, including height, area, frame material, and filling volume. It can replace models from major global brands.
Q: 6. What tests can your filters pass?
A: SO₂ removal, H₂S adsorption, alkaline gas neutralization, VOC degradation, air resistance testing, and sealing testing can all be performed according to EN/ISO standards.
Q: 7. Will secondary pollution occur after the chemical media becomes saturated?
A: No. We use highly stable oxidizing and impregnating media that do not release adsorbed pollutants after saturation.
Q: 8. Do you have filters suitable for high humidity environments?
A: We provide dedicated "moisture-resistant chemical media" that maintain stable performance in environments with 80–95% RH.
Q: 9. Can the filling media be purchased separately?
A: Yes. Media can be supplied in bags, drums, and ton bags, and comes with a COA and MSDS.
Q: 10. Can you provide a complete AMC solution?
A: Yes. Complete projects including chemical filter media, chemical filter boxes, monitoring systems, pipeline modifications, and energy-saving optimizations.
