Due to the different environments, it is difficult to estimate the difference in the data, and if there is a little more furniture, I personally think that the data will be slightly higher for 12 hours.
Find the State Environmental Quality Supervision, Inspection and Quarantine Bureau for testing.
It's formaldehyde testing, right? Many third-party testing agencies can, and we can also issue authoritative test reports.
Why should I test for toilet odor? Is it freshly renovated? If so, you can directly use activated charcoal and Shi Shanglong to remove the deodorant.
Look at what the test is, PSE, SG or what, different signs have different bodies.
The national fire prevention inspection department can be found directly on the official website, you can actually look at it.
