How much is the formaldehyde detection value exceeding the standard?

Before moving into a new home, everyone is most concerned about whether the indoor formaldehyde detection air quality formaldehyde value is up to standard.

Is it safe to live in it?

Therefore, it has become the common sense of urban residents to detect formaldehyde before moving into a new house?

So how many indicators can formaldehyde stay in?

Some people say 0. 1mg/m3, others say 0.08mg/m3.

Which is more standard?

Let's look at the national formaldehyde standard first:

The first is the delivery acceptance standard required by the Ministry of Housing and Urban-Rural Development.

The formaldehyde content in indoor air is ≤ 0.08 mg/m.

It is required to seal doors and windows 1 hour in advance before testing.

? The second is the occupancy standard required by the Ministry of Health.

The formaldehyde content in indoor air is ≤ 0.1mg/m.

It is required to seal doors and windows 12 hours in advance before testing.

The second criterion is closer to people's living conditions.

Therefore, at present, the standard of formaldehyde detection is usually ≤0. 1mg/ m3.

So what does the formaldehyde concentration standard of 0. 1 mg/m3 mean?

Does the formaldehyde concentration in the new home meet this standard?

In fact, the limit is 0. 1 mg.

It is safe for human health.

But there is one problem that must be pointed out.

This standard is based on the current level of scientific cognition.

In other words, with the improvement of scientific research level.

We can't rule out the future

The possibility that this safety standard is unsafe.
