Is it illegal to operate a hotel room with excessive formaldehyde?

Not illegal. According to the information of China Travel Service. Com, the hotel is a profit-oriented service industry, and the law of our country does not clearly stipulate that hotels with excessive formaldehyde cannot open, so it is not illegal to operate rooms in hotels with excessive formaldehyde. But hotels should focus on the interests of customers, not just their own economic interests. Once the hotel finds that formaldehyde in the air exceeds the standard, it should first inform the guests of the fact that formaldehyde exceeds the standard and take effective measures to solve it as soon as possible.
