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 use high-quality synthetic fiber filter media from well-known brands. They are mainstream intermediate filtration products for industrial and commercial ventilation systems, offering advantages such as high airflow, low resistance, high dust-holding capacity, and long service life. The outer frame is made of aluminum alloy with thicknesses of 21mm, 25mm, and 46mm. The filter media uses medium-efficiency synthetic fiber filter bags, operating on the principle of air pressure adsorption filtration, primarily targeting particles ≥1μm. Filtration efficiencies are classified as F5 (45%), F6 (65%), F7 (85%), and F8 (98%) (atmospheric dust colorimetric method), strictly adhering to the GB/T 14295-2019 quality standard. The products utilize hot-melt seamless bonding technology, eliminating the risk of air or dust leakage. They serve as intermediate filtration stages in central air conditioning, cleanrooms, and industrial air intake systems, effectively protecting downstream high-efficiency filters. Non-standard sizes, bag counts, and efficiencies can be customized to meet diverse intermediate filtration needs.

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?
Not recommended for washing; synthetic fiber filter media loses efficiency and is prone to damage and dust leakage after washing. Replace every 3-6 months in normal environments; inspect every 1-3 months in high-dust industrial environments. Replace promptly when 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 capture particles ≥5μm as the first stage; bag-type medium efficiency filters capture particles ≥1μm as the second stage, primarily protecting downstream high-efficiency filters. Using them together extends the overall life of the purification system.
