F5 Medium Efficiency Filter
The core function of the F5 Medium Efficiency Filter is to accurately capture fine dust, pollen, fibers, and various airborne particulates ranging from 1–5 μm in size, with a filtration efficiency of 40%–60%.
Constructed from high-quality filter media and a sturdy frame, it features low air resistance and high dust-holding capacity.
Compatible with a wide range of applications and requiring minimal maintenance, it is an economical and practical choice for ventilation and air purification in commercial, industrial, and public facilities, balancing filtration performance and operating costs.
Product Introduction
Products Description
The F5 Medium Efficiency Filter is a key filtration component in ventilation and air purification systems. It mainly captures dust, lint, pollen, and suspended particles of 1–5 μm in the air, with stable and compliant filtration efficiency that effectively improves supply air cleanliness. Featuring a bag-type structure, it offers good air permeability, high dust-holding capacity, and low operating resistance, which reduces fan load and energy consumption. With a sturdy, flat outer frame and excellent sealing performance, it is easy to install and replace. Suitable for shopping malls, office buildings, workshops, hotels, central air conditioning systems, and other scenarios, it delivers stable performance, high durability, and low maintenance costs, making it a cost-effective and widely used key filtration part for various ventilation systems.

Product Advantages
High-Quality Materials, Durable
The filter medium is resistant to fracture and aging, and not easily damaged. The outer frame is made of high-quality materials such as aluminum alloy and galvanized sheet, which are corrosion-resistant and rust-proof, adapting to different humidity and temperature environments.
Low Resistance and Energy Saving, Efficient Operation
The optimized bag-type structure design provides a large effective filtration area, with an initial resistance of only 50Pa. This can greatly reduce the fan load of the ventilation system, lower energy consumption, and significantly save operational costs during long-term use.
Easy to Install and Replace
The standardized structure design simplifies installation, making it suitable for various conventional ventilation systems. When replacing the filter, only the filter bag needs to be replaced, which is convenient and quick to operate, greatly saving maintenance time and labor costs.
Green and Environmentally Friendly
The filter medium is made of environmentally friendly and non-toxic materials, with no odor or secondary pollution, complying with national environmental protection standards.

Q:What is the service life of the F5 Medium Efficiency Filter?
A:Under normal operating conditions, its service life is 3-4 months; if the dust concentration in the operating environment is high, the service life will be correspondingly shortened. When the filter resistance reaches more than 400Pa, it must be replaced.
Q:What is the filtration efficiency of the F5 Medium Efficiency Filter?
A: The filtration efficiency of the F5 Medium Efficiency Filter is 40%-60% @1-5μm (colorimetric method), mainly intercepting particulate matter of 1-5μm.
Q:What are the installation requirements for the F5 Medium Efficiency Filter?
A: The installation requirements are simple. It is only necessary to ensure good airtightness at the edge-pressing part of the filter and the frame to prevent air leakage. During installation, the length direction of the filter bag opening should be perpendicular to the ground to ensure the air supply filtration effect and service life. Avoid placing the filter on the downwind side of a sprinkler room or humidifier; if unavoidable, protective measures must be taken. Do not strike the filter surface with heavy objects or pull the filter medium forcefully.
