After decorating a new house, formaldehyde is a common harmful gas, which comes from various decoration materials and furniture, such as glue, paint, plates, etc. Formaldehyde is very harmful to the human body, can cause headaches, dizziness, nausea and other symptoms, and in severe cases, may even lead to poisoning and cancer. Therefore, it is very necessary to ventilate new houses to remove formaldehyde.
So, how long does it take to ventilate a new house to get rid of formaldehyde?
First of all, we must understand the principle of ventilation to remove formaldehyde. Ventilation is the convection of air to expel formaldehyde from the indoor and outdoor. Therefore, the effectiveness of ventilation depends on the concentration of formaldehyde in the room and the intensity of ventilation. Generally speaking, for a newly renovated house, it needs to be ventilated for at least 3 months to effectively reduce formaldehyde concentration.
However, ventilation alone is not enough. Because formaldehyde is released for up to 3-15 years, more effective measures need to be taken to remove formaldehyde.
First of all, it is necessary to choose decoration materials and furniture with low formaldehyde. When purchasing decoration materials and furniture, you should choose environmentally friendly materials that meet the national standards of E0 or above, and try to avoid using materials with high formaldehyde content.
Secondly, you can use Wise Stone,It is a natural mineral with a strong ability to adsorb and decompose formaldehyde. Not only does it remove formaldehyde, but it also removes odors, mold and moisture, making it very practical. And it can be used for three years without replacement, which is very convenient.
In addition, you can also use Muguang Blue. It can quickly penetrate the inside of the pollution source, induce formaldehyde and break it down into harmless water and carbon dioxide. What's more, it is very safe to use and does not require any special conditions.
In short, how long it takes to get rid of formaldehyde when ventilating a new house depends on a variety of factors, including the concentration of formaldehyde in the room, the intensity of ventilation, and the formaldehyde removal measures taken.
Generally speaking, ventilation for more than 3 months can effectively reduce formaldehyde concentration, but in order to remove formaldehyde more comprehensively, other effective measures are needed. At the same time, we should also pay attention to maintaining indoor air circulation to avoid excessive indoor formaldehyde concentration and harm to health.
