According to Article 4 of the Measures for the Supervision and Administration of Drinking Water Hygiene (Order No.53 of the Ministry of Construction and the Ministry of Health), "The state implements a hygiene license system for water supply units and products related to drinking water hygiene and safety." Article 21: "Protective coatings, water quality processors, new materials and chemicals that come into contact with drinking water shall be submitted to the Ministry of Health for examination after preliminary examination by the health administrative department of the provincial people's government; The products that pass the re-inspection shall be issued with approval documents by the Ministry of Health.

With "Sperling" as the key word, no legal approval number can be found.

Please confirm that the brand of the product is "Sperling". If the manufacturer is "Sperling" and the product has another trademark, it may cause query errors.

Unapproved products cannot be sold as drinking water processors.

The Health Planning Commission (formerly the Ministry of Health) can view the following entrances to official website:

Some people who don't know or knowingly commit crimes will have objections to the examination and approval. If you think that the cited laws and regulations are improper, you can tell me the order number of the State Council when the Measures for the Supervision and Administration of Drinking Water Hygiene was abolished. If you agree with the laws and regulations, but think my statement is wrong, your brand has an approval, you can tell me the approval number you obtained. If my inquiry is wrong as you said, I will sincerely apologize to you.

Honesty and legality can be a sustainable business.
