How can you tell whether an eco-friendliness grade for whole-house customization is genuine?

To tell whether an eco-friendliness grade is genuine, do not rely only on what the salesperson says. You can ask to see the board's test report and eco-friendliness grade label, and check the grade, testing institution, and batch information on the report; when you visit the factory, look at the board packaging and edge banding process—poor edge banding means a stronger odor. Our eco-friendliness grades are available in HENF, ENF, E0, FAS, and F4 star; cabinet bodies come with a ten-year warranty and are returnable if not environmentally compliant—only what is written into the contract counts. After installation, have a third party test the air; it is reliable only when the report matches the contract.
