The national standard of indoor formaldehyde is 0.08mg/m3, because there are many materials that release formaldehyde, when the ventilation is a little worse, there will be the possibility of formaldehyde exceeding the standard, which can not be completely removed in a short time, which is also the reason why the treatment of formaldehyde will be repeated. So how should we deal with it and recommend several long-term effective methods to everyone.

1. Plants can remove formaldehyde. Although they can remove formaldehyde, the amount of formaldehyde they absorb is very limited, and when the indoor concentration is high, if only plants absorb formaldehyde, the amount is very large.

2. If the newly renovated house wants to remove formaldehyde and odor in the room as soon as possible, the first thing to do is to open the window for ventilation. At the same time, doors and drawers can be opened, and formaldehyde can be diluted by air convection and put outdoors. Although this step is simple, we should also pay attention to the weather so as not to damage the newly renovated home environment due to strong winds and heavy rains.

5. The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a solid film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and utilize the photocatalytic performance of photocatalyst to oxidize formaldehyde. However, the film may be oxidized and worn in daily life, and the effect will be halved.

6. There are many companies in in addition to formaldehyde and they adopt different methods. Commonly used methods are plugging method, oxidation method and catalysis method. If it is a reliable company, the effect is obviously that the price is slightly higher?
