Product Details
1. Product Introduction
Shenzhen Mingyang Purification Technology Co., Ltd.Deeply rooted in the air filtration field for over 20 years, we professionally produce various air filters and HVAC filter screens, covering primary, medium, and high-efficiency categories. Widely used in industrial purification, central air conditioning, clean rooms, and other scenarios, we are a core manufacturer of paper frame primary efficiency filters in China.
Mingyang CPP paper frame primary filter is an economical primary filtration product that emphasizes low cost, light weight, versatility, and compactness. It strictly followsGB/T 14295-2019Manufactured to national standards. The product uses a hard cardboard frame with primary synthetic fiber filter media, with a metal mesh added on the back of the folded media for reinforcement, effectively preventing media deformation and collapse, ensuring filtration stability. Filtration efficiency is available in G3 (80%) and G4 (90%), targeting airborne particles ≥5μm. Frame thickness options include 21mm, 46mm, and 96mm to suit different installation depth requirements. It meets primary filtration needs in scenarios such as HVAC, air compressors, and clean room return air, serving as an economical disposable pre-filter option. Non-standard sizes can be customized to fit special installation spaces.
2. Key Product Features
- 2.1 Extremely high cost performance, controllable costsThe hard cardboard frame material is low-cost, making the overall price affordable, suitable for bulk procurement and use, significantly reducing upfront purchase and later replacement costs for ventilation systems. It is the first choice for budget-limited scenarios.
- 2.2 Light weight and excellent versatilityThe lightweight design of the paper frame material eliminates the need for heavy tools during handling, installation, and removal. It is compatible with most standard ventilation cabinets and air conditioning units, offering high versatility without requiring custom modifications.
- 2.3 Compact structure, small footprintThe pleated design provides a large filtration area while keeping the unit slim and lightweight, with a thickness starting from just 21mm. It fits into tight installation spaces without occupying excess internal equipment volume.
- 2.4 Metal mesh support for stable operationA metal protective mesh is installed on the air outlet side of the filter media to prevent deformation or shedding under airflow impact. This ensures stable filtration performance over long-term operation, with no risk of air leakage or dust bypass.
- 2.5 High airflow and low resistance for smooth ventilationThe synthetic fiber filter media offers excellent air permeability, and the pleated structure increases the filtration area. While maintaining filtration efficiency, it provides low initial resistance and high airflow, without adding load to the ventilation system.
3. Product Applications
3.1 Pre-filtration for air conditioning and ventilation systems
As the first-stage filtration device for central air conditioning and centralized ventilation systems, it efficiently intercepts large particles, hair, and fibrous materials in the air, protecting downstream medium and high-efficiency filters, extending the lifespan of high-end filtration equipment, and reducing overall maintenance costs.
3.2 Pre-filtration for industrial equipment air intake
Used for intake pre-filtration of large industrial equipment such as air compressors and fans, preventing dust from entering the equipment and causing component wear, ensuring continuous and stable operation of industrial equipment, and reducing equipment failure and downtime.
3.3 Filtration for cleanrooms and purification devices
Suitable for clean room return air filtration systems, maintaining basic indoor cleanliness; also serves as pre-filtration for local high-efficiency filtration devices, sharing the filtration load and extending the service life of high-efficiency filters.
3.4 Multi-Industry Universal Air Purification
Widely used in industries such as electronics, food, pharmaceuticals, hospitals, and aviation that require basic air purification. As a primary air filtration product, it meets daily ventilation and air cleaning needs.

5. FAQ
5.1 Can the CPP paper frame primary filter be cleaned and reused?
Not recommended for cleaning. This is a disposable economical filter. The paper frame is prone to deformation and damage when wet, and the filter media cannot be restored to efficiency by washing. Replace it directly when the resistance reaches the limit; cost-effectiveness is far higher than cleaning and maintenance.
5.2 How to choose the thickness of the CPP paper frame filter?
Choose 21mm for tight installation spaces; 46mm (2 inches) for conventional HVAC; 96mm (4 inches) for larger filtration area, lower resistance, and longer service life. Match the depth of the equipment installation slot.
5.3 How to choose between G3 and G4 efficiency?
Choose G3 for general civil ventilation and general industrial pre-filtration; choose G4 for environments with basic air cleanliness requirements such as shopping malls, hospitals, electronics workshops, and clean room return air. Select flexibly based on scenario cleanliness needs.
5.4 What is the replacement cycle for paper frame filters?
Replace every 1-3 months in normal environments; in high-dust industrial environments, check every 2-4 weeks. Replace promptly when the initial resistance doubles to ensure ventilation and filtration effectiveness.
