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-type medium efficiency filters are mainstream intermediate filtration products commonly used in industrial and commercial ventilation systems. They are made of high-quality branded synthetic fiber filter media, offering core advantages such as large effective filtration area, high airflow, low resistance, high dust holding capacity, and long service life. The outer frame is made of aluminum alloy, available in thicknesses of 21mm, 25mm, and 46mm. The filter media is medium efficiency synthetic fiber filter bags, using air pressure adsorption as the filtration principle, mainly filtering dust particles ≥1μm. The colorimetric filtration efficiency covers multiple grades: F5 (45%), F6 (65%), F7 (85%), F8 (95%), F9 (98%), strictly complying with GB/T 14295-2019 quality standards. The product adopts a bag structure and hot melt seamless bonding process, eliminating the risk of air leakage and dust leakage. It can be used as the intermediate filtration stage in central air conditioning, centralized ventilation systems, and clean rooms, effectively protecting downstream high efficiency filters and extending the service life of high-end filtration equipment. Non-standard sizes, number of bags, and efficiency customization are supported to meet various intermediate filtration needs in different scenarios.

5. FAQ
5.1 How to select F5/F6/F7/F8 bag-type medium efficiency filters?
F5 (white): Suitable for general central air conditioning and general ventilation intermediate pre-filtration. F6 (green): Suitable for shopping malls, office buildings, and other conventional commercial spaces. F7 (pink): Suitable for hospitals, electronics workshops, and food factories. F8 (yellow): Suitable for high-standard purification scenarios such as pharmaceuticals, precision instruments, and biomedical applications.
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 What is the difference between bag-type medium efficiency and primary efficiency filters?
Primary efficiency filters mainly filter large particles ≥5μm as the first stage of the system; bag-type medium efficiency filters filter fine particles ≥1μm as the second stage. The core function is to protect downstream high efficiency filters. Using them together can significantly extend the life of the purification system.
