Frequently Asked Questions
-
Q: What is the difference between G3 and G4 filtration grade?
A: G3 captures particles >10 μm (e.g., coarse dust) with average efficiency >90%. G4 captures finer particles >5 μm, offering higher efficiency for cleaner air. Both are suitable for pre-filtration in HVAC systems. We can supply either grade based on your requirement. -
Q: Can I get a custom size for my air handler?
A: Yes, we produce filters in any dimensions. Just provide the length, width, and thickness you need. Custom sizes are our specialty – no minimum order quantity for standard customization. -
Q: What is the typical lead time?
A: For standard sizes, lead time is 7–10 working days. Custom sizes require 10–15 working days, depending on quantity. We ship via sea or air from major Chinese ports. -
Q: Is the filter washable or disposable?
A: Our polyester filters are typically disposable. However, depending on the application, some customers clean them with compressed air (low pressure) for limited reuse. We recommend replacing after 3–6 months for optimal performance. -
Q: Do you provide samples before bulk order?
A: Yes, we offer free samples (shipping cost paid by buyer). Sample production takes 3–5 days. We can also provide a Mill Test Report for the sample. -
Q: What is the warranty coverage?
A: The 1-year warranty covers manufacturing defects such as media tear, frame deformation, or poor sealing. It does not cover damage caused by misuse or improper installation. Our technical support team can assist with any issues. -
Q: How do I install the flange-clamp filter?
A: The filter slides into the duct or housing and is secured by tightening the clamp bolts around the flange. No tools are required. Detailed installation instructions are included with each shipment. -
Q: Can I order filters with different colors for my facility?
A: Yes, we can supply white, blue, black, or custom colors. Color coding helps identify filter grades or maintenance zones. Please specify your color request when ordering.
