Q: Where can I purchase replacement filters? 
A: You can scan the QR code on the machine to purchase replacement filters. Alternatively, you can contact us and we will provide the purchase link.

Q: How often should I replace the filters? 
A: The first-stage pre-filter cotton should generally be replaced every 7–15 days, the second-stage high-efficiency filter should typically be replaced every 3–6 months. Actual replacement intervals may vary depending on usage time and smoke volume. If the unit is no longer effectively capturing smoke, it is time to replace the filter.

Q: How do I know when the filters need to be replaced? 
A: If the machine stops extracting smoke effectively or emits a beeping alarm, first replace the first-layer filter and test the machine. If performance does not improve, replace the second-layer filter. Continue checking each filter layer as needed until normal suction is restored.

Q: What should I do if my fume extractor is not working properly? 
A: Please refer to the user manual for troubleshooting instructions. If the issue persists, contact us for further assistance.

Q: What does the beeping sound mean? 
A: The beeping sound is the filter replacement alarm, indicating that the filters may need to be replaced. If the filters are still usable and the machine maintains sufficient suction, you can increase the negative pressure sensitivity.
