Product Details
1. Product Introduction
Shenzhen Mingyang Purification Technology Co., Ltd. has been deeply engaged in the air filtration field for over 20 years, specializing in the production of various air filters and air conditioning filter nets. The products cover all categories of pre-filters, medium-efficiency filters, and high-efficiency filters, widely used in industrial purification, central air conditioning, clean rooms, etc., making it a core manufacturer of paper frame pre-filters in China.
Mingyang CPP Paper Frame Pre-filter is an economical primary filtration product that emphasizes low cost, lightweight, versatility, and compactness, strictly produced in accordance with GB/T 14295-2019 national standards. The product features a hard cardboard outer frame combined with primary synthetic fiber filter cotton, with a folded filter material supported by a metal mesh on the back to effectively prevent deformation and collapse, ensuring stable filtration. The filtration efficiency is divided into G3 (80%) and G4 (90%), primarily targeting dust particles ≥5μm in the air. The outer frame thickness offers three options: 21mm, 46mm, and 96mm, corresponding to different installation depth requirements, suitable for various scenarios such as air conditioning ventilation, air compressors, and clean room return air. It is an optimal choice for disposable economical pre-filtration and supports non-standard specifications customization to fit various special installation spaces.
2. Core product features
- 2.1 Extremely cost-effective, controllable costs: The cardboard frame material is inexpensive, and the overall price is affordable, making it suitable for bulk purchases, significantly reducing the initial procurement and later replacement costs of the ventilation system, making it the first choice for budget-limited scenarios.
- 2.2 Lightweight and highly versatile: The paper frame material is designed to be lightweight, allowing for easy handling, installation, and disassembly without heavy tools, compatible with the vast majority of standard ventilation cabinets and air conditioning units, with high universality and no need for exclusive adaptation or modification.
- 2.3 Compact structure, occupying little space: The folded structure design provides a large filtration area while being slim, with a thickness starting at only 21mm, making it suitable for narrow installation spaces without occupying excess volume inside the equipment.
- 2.4 Metal mesh support, stable operation: The filter material's air outlet surface is equipped with a metal protective mesh to prevent deformation and shedding of the filter material due to airflow impact, ensuring stable filtration performance over long-term operation without risks of air or dust leakage.
- 2.5 Large air volume and low resistance, smooth ventilation: The initial efficiency synthetic fiber filter material has good air permeability, and the folded structure expands the filtration area, ensuring low initial resistance and high air volume without increasing the load on the ventilation system.
3. Product application range
3.1 Pre-Filtering for Air Conditioning and Ventilation Systems
As the first-stage filtering device for central air conditioning and centralized ventilation systems, it efficiently intercepts large particles of dust, hair, and fluff in the air, protecting the downstream medium and high-efficiency filters, extending the service life of high-end filtration equipment, and reducing overall operation and maintenance costs.
3.2 Pre-Filtering for Industrial Equipment Inlet Air
Used for pre-filtering the intake of large air compressors, fans, and other industrial equipment, preventing dust from entering the equipment and causing wear on components, ensuring continuous and stable operation of industrial equipment, and reducing the probability of equipment failure and downtime for maintenance.
3.3 Filtering for Clean Rooms and Purification Devices
Compatible with cleanroom return air filtration systems to maintain basic indoor cleanliness; it can also serve as a pre-filter for local high-efficiency filtration devices, sharing the filtration load and extending the service life of high-efficiency filters.
3.4 General Air Purification for Multiple Industries
Widely used in industries such as electronics, food, pharmaceuticals, hospitals, and aviation, which have basic air purification requirements, serving as a basic air filtration product to meet daily ventilation and air purification needs.

5. Frequently asked questions
5.1 Can the CPP paper frame pre-filter be cleaned and reused?
Washing is not recommended. This product is a disposable economical filter; the paper frame deforms and damages easily when wet, and the filter material cannot be washed to restore efficiency. Once the resistance reaches its limit, it should be replaced directly, offering far better cost-effectiveness than cleaning and maintenance.
5.2 How to choose the thickness of the CPP paper frame filter?
For narrow installation spaces, choose 21mm; for conventional air conditioning ventilation, choose 46mm (2 inches); for a larger filtration area, lower resistance, and longer service life, choose 96mm (4 inches), which can be matched according to the depth of the equipment installation slot.
5.3 How to choose between G3 and G4 efficiency?
For ordinary civil ventilation and general industrial pre-filtration, choose G3; for places with basic air cleanliness requirements such as shopping malls, hospitals, electronic workshops, and cleanrooms, choose G4, allowing flexible selection based on cleanliness needs.
5.4 What is the replacement cycle for paper frame filters?
Under normal conditions, replace once every 1-3 months; in industrial environments with high dust concentration, it is recommended to check every 2-4 weeks, and replace with a new product promptly when the initial resistance reaches twice the initial resistance, ensuring ventilation and filtration effectiveness.
