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 HD/SE bag medium efficiency filter is the most commonly used medium-grade filtration product in industrial and civil ventilation systems. It uses high-quality branded chemical fiber filter media, offering core advantages of high airflow, low resistance, high dust holding capacity, and long service life. The outer frame is made of aluminum alloy profiles, available in thicknesses of 21mm, 25mm, and 46mm. The filter media is medium-efficiency synthetic fiber filter bags, using the pressurized air adsorption method for filtration, primarily capturing ≥1μm dust particles. Filtration efficiencies cover F5 (45%), F6 (65%), F7 (85%), and F8 (95%) (atmospheric dust colorimetric method), with the F7 pink series being the mainstream market choice. Strictly complies with GB/T 14295-2019 quality standards. The product adopts a bag structure with hot-melt seamless bonding technology, eliminating the risk of air and dust leakage. It can be used as a medium-grade filtration stage in central air conditioning, centralized ventilation systems, and cleanrooms, effectively protecting downstream HEPA filters and extending the service life of high-end filtration equipment. Non-standard sizes, bag counts, and efficiencies can be customized to meet various medium-grade filtration needs.

5. FAQ
5.1 What are the application scenarios for F7 bag medium efficiency filters?
F7 (pink) is suitable for places with high air cleanliness requirements such as hospitals, electronics workshops, food factories, shopping malls, and office buildings. It serves as medium-grade filtration in central air conditioning and cleanrooms, effectively protecting downstream HEPA filters.
5.2 Can bag-type medium efficiency filters be cleaned? How often should they be replaced?
Cleaning is not recommended; synthetic fiber filter media loses efficiency significantly after washing and is prone to damage and dust leakage. Under normal conditions, replace every 3-6 months; in high-dust industrial environments, inspect every 1-3 months and replace when the initial resistance reaches twice the initial value.
5.3 How to select F5/F6/F7/F8 filters?
F5 (white) for general ventilation pre-filtration; F6 (green) for conventional commercial places; F7 (pink) for hospitals, electronics, and food industries; F8 (yellow) for pharmaceutical, precision instruments, and other high-standard purification scenarios.
