How to correctly detect whether formaldehyde exceeds the standard?

Excessive formaldehyde poses a serious threat to the human body, so in daily life, we should of course pay attention to preventing formaldehyde and detect whether the formaldehyde level exceeds the standard. We can use the sensory method, calculation method or ask a professional indoor pollution detection company to detect it.

1. Feeling method,

After decoration, fully ventilate the room for 7-15 days, close the doors and windows for 24 hours, and then enter the room. If you feel glaring or pungent, then the formaldehyde in your room is likely to exceed the standard by more than 4 times. (If only the furniture feels glaring or pungent, then the formaldehyde in your indoor space may also exceed the standard by about 2 times).

2. Calculation method

Based on how many boards you used in your renovation, multiply the unfolded surface area of ​​the purchased furniture by the formaldehyde test index in the relevant information provided to you by its manufacturer. Then divide it by the spatial volume of your entire room, that is, the practical area multiplied by the height from the ground to the ceiling (since the credibility of the manufacturer's data is almost 0, the actual use value of this method is limited).

3. Please ask a professional indoor pollution detection and treatment company to conduct detection and treatment. This is the most accurate method to determine whether formaldehyde exceeds the standard.
