    Frequently Asked Questions (FAQ)
    What is the main purpose of an air pre-filter media?
    The main purpose of an air pre-filter media is to capture larger particulate matter before it reaches the main filter. This helps sustain the life of the main filter, reduces replacement frequency, and lowers overall maintenance costs.
    What filter grades are available for this media?
    The pre-filter media is available in a variety of grades including G2, G3, G4, as well as MERV 5, 6, 7, and 8, allowing it to meet specific air quality requirements for different applications.
    What material is the pre-filter media made from?
    It is made from top-grade synthetic polyester fibers that are highly effective at retaining larger particles while maintaining optimal airflow.
    What is the maximum temperature this filter media can withstand?
    The filter media is designed to withstand temperatures up to 100°C, making it suitable for a wide range of HVAC system environments.
    How does this filter media help reduce energy costs?
    It is engineered for minimum airflow resistance, meaning your HVAC system doesn't have to work as hard to push air through. This improves energy efficiency and directly reduces the operating costs associated with HVAC functions.
    Can the specifications of the filter media be customized?
    Yes. While it comes in normal sizes like 1*20m and 2*20m with thicknesses ranging from 5mm to 22mm, other specifications can be customized according to specific customer requirements and dust-loading applications.
