The test results are normal, but the appearance of the product is affected, which poses a certain risk to the high-end development of the product. It is necessary to use a filtering device to filter it to improve its appearance quality.

[0004] The prior art patent document with publication number CN211435300U provides a high-precision filtering device for a formic acid product. The filtering device can effectively remove impurities such as floccules in the formic acid and improve its appearance quality. The filtering device can achieve formic acid removal while also being able to adjust and control the pressure balance in the tank to ensure normal filtration and process the volatilized gaseous formic acid to prevent it from polluting the workshop environment.
