Activated carbon air purification filter screen can be customised to meet customer requirements and application scenarios, available in both flat-panel and ring-shaped configurations.

Flat-panel activated carbon air purification filters are a best-selling air filtration component on the international market. Made from high-purity activated carbon base paper, they feature abundant microporosity and stable adsorption properties, effectively removing formaldehyde, benzene compounds, TVOCs, smoke particles and odours; The integrated flat panel is fitted with a reinforced protective mesh, making it robust and resistant to deformation. It features low air resistance, good air permeability, high dust-holding capacity and a long service life, whilst being easy to install and remove. Suitable for air purifiers, fresh air systems, central air conditioning and ventilation equipment, it is used in residential properties, hotels, office buildings, hospitals and industrial premises. Manufactured in accordance with international standards, the product range is comprehensive and available for customisation and bulk supply. Offering excellent quality at competitive prices, it has received widespread acclaim from overseas buyers, distributors and engineering clients.

The ring-shaped mesh utilises a composite moulding process, making it suitable for circular purification and ventilation equipment; high-adsorption filter paper provides deep purification of formaldehyde, VOCs, dust and odours. The ring-shaped design fits the equipment snugly, whilst the double-layer protective mesh is wear-resistant, stable and maintains its shape over time. With low air resistance, high permeability and a large dust-holding capacity, it enables more energy-efficient equipment operation and extended replacement intervals, making it suitable for cylindrical purifiers, commercial fresh air ducts and industrial ventilation systems. Inner and outer diameters, thickness, and activated carbon content are all customisable. With rigorous quality control and ample stock for export, we offer a one-stop procurement service for overseas wholesalers and engineering contractors.

Selected applications

Domestic / commercial air purifiers

Main filtration layers: Pre-filter (activated carbon paper) + HEPA, for removing formaldehyde, TVOCs, smoke odours and pet odours.

Structure: Flat-panel activated carbon air purification filter (low air resistance, large surface area).

Central air conditioning and fresh air systems

Duct / unit-mounted: G4–F8 grade, removes odours from fresh air, VOCs and ozone, and protects terminal equipment.
Features: High airflow, low pressure drop, long service life (3–6 months).
Structure: Ring-shaped activated carbon air purification filter

Car Air Conditioning

Air conditioning filter: Activated carbon paper + non-woven fabric, removes formaldehyde, benzene, exhaust fumes and PM2.5 from the vehicle interior.

Industrial Exhaust Gas Treatment

Low concentration, high airflow: Spray painting, printing, chemical and electronics factories; treats benzene, toluene, xylene, esters, alcohols and malodorous gases.

Structure: Flat-panel activated carbon air purification filter

Special Applications

Medical: Operating theatres, ICUs, laboratory fume cupboards; removes odours and harmful gases.

Protection: Gas masks, respirators; adsorbs toxic vapours.

Pets / Livestock: Removes ammonia and odours; improves air quality.

Appendix: Our Company's Testing Methods and Results

1. Test Equipment: 8m³ test chamber

2. Test Method: A fixed quantity of five gases (acetaldehyde, acetic acid, ammonia, toluene, formaldehyde) was introduced into the 8m³ test chamber. After introduction, the air purifier was operated for 30 minutes, following which the gas composition within the chamber was analysed using FT-IR.

3. Test Results: Odour removal efficiency: 99.9%.
