Product Details
1. Product Introduction
Shenzhen Mingyang Purification Technology Co., Ltd. Specializing in the production of air filters, including primary filters, medium filters, high-efficiency filters, and air conditioning filter screens, widely used in central air conditioning systems, clean rooms, and industrial air purification.
Mingyang W-type sub-HEPA filter is a compact pleated filter product specially designed for central air conditioning and centralized ventilation systems. It is divided into two types: MZ/P polypropylene fiber series and MZ/G ultra-fine glass fiber series. The frame is integrally molded from ABS plastic, with an overall thickness of 292mm and a flange thickness of 25mm. It adopts a W-type pleated structure (2V/3V/4V). The filtration efficiency is divided into H10, H11, and H12 according to the MPPS method, mainly capturing ultra-fine dust particles ≥0.3μm in the air, strictly complying with the national standard GB/T 14295-2019. The product uses air pressurized adsorption as the core filtration principle, featuring large effective filtration area, low resistance, long service life, and small footprint. The MZ/P series can be 100% incinerated, fully meeting environmental emission requirements. It is widely used in ventilation purification needs in electronics, food, pharmaceuticals, hospitals, optics and other industries, and supports non-standard size customization to fully meet the installation and filtration requirements of different ventilation systems.
2. Key Product Features
- 2.1 Dense pleat structure, large filtration area, low resistanceThe W-type pleated design greatly increases effective filtration area, resulting in low initial resistance, higher airflow, gradual resistance increase over time, and significantly extended service life.
- 2.2 Compact design, saves installation spaceIntegrated thin structure with thickness of only 292mm, allowing more compact design of central air conditioning and ventilation systems, suitable for space-constrained installations.
- 2.3 Dual filter media options, balancing environmental protection and stabilityMZ/P polypropylene fiber media is 100% incinerable, environmentally friendly with no solid waste burden; MZ/G fiberglass media offers stable performance and lasting filtration efficiency. Flexible selection based on needs.
- 292mm, flange thickness 25mmEnsures high filtration efficiency while achieving stable high-volume airflow, with no efficiency degradation or deformation during long-term operation, suitable for continuous ventilation scenarios.
- 2.4 Sufficient air volume, stable operating performanceABS plastic frame offers high strength and light weight. Standardized flange dimensions allow direct connection to various air handling units and fume hoods, easy to install without complex construction.
3. Product Applications
3.1 Central air conditioning and centralized ventilation systems
Intermediate/sub-HEPA filtration for commercial/industrial central air conditioning and large centralized ventilation systems, effectively intercepting ultrafine dust, smoke, and microorganisms ≥0.3μm, ensuring supply air cleanliness and protecting downstream high-efficiency filters.
2.5 Standardized structure, easy installation and replacement
Ventilation purification in electronics factories, food processing, pharmaceutical workshops, hospital diagnosis areas, and optical instrument workshops. Acts as pre-protection for HEPA filters, sharing filtration load and extending HEPA filter life.
3.3 General industrial and commercial purification
Ventilation purification in large commercial venues such as shopping malls, office buildings, airports, and high-speed rail stations; filtration in industrial plants and laboratory ventilation systems, suitable for various ventilation scenarios with space and environmental requirements.

5. FAQ
5.1 How to select between MZ/P and MZ/G series?
For environmental disposal needs and cost-effectiveness, choose MZ/P polypropylene series (incinerable); for filtration stability and long service life, choose MZ/G fiberglass series. Flexible selection based on working conditions and environmental requirements.
5.2 What is the replacement cycle for W-type sub-HEPA filters?
Replace every 6-8 months in normal ventilation environments; every 3-4 months in high-dust clean scenarios. Replace immediately when initial resistance doubles to ensure ventilation and filtration performance.
5.3 Can the W-type filter be cleaned and reused?
Not washable. The pleated filter media structure is precise; washing causes media deformation, efficiency drop, and dust leakage. This is a disposable filter; replace directly upon expiration.
5.4 How to choose H10/H11/H12 efficiency levels?
Choose H10 for general central air conditioning ventilation; H11 for commercial clean areas and general hospital areas; H12 for electronics, pharmaceutical, and optical workshops with higher cleanliness requirements.
