1. Distinguish wood smell and formaldehyde.
1.Olfactory discrimination.
Formaldehyde is an organic compound that has a strong pungent odor. Therefore, formaldehyde and wood smell can be preliminarily distinguished by the sense of smell. Generally speaking, formaldehyde has a strong taste, while wood has a relatively light taste. However, it should be noted that some man-made panels will add some flavors to mask the smell of formaldehyde during processing, so it is not completely reliable to rely on olfactory discrimination alone.
2.Chemical detection reagents.
There are some chemical detection reagents on the market that can be used to detect indoor formaldehyde levels. These reagents are usually some liquids or test strips with special chemical compositions, and they are placed in various corners of the room when used, waiting for a period of time to observe the change of color to judge the formaldehyde content. These reagents are highly accurate, but need to be purchased and used correctly according to the instructions.
3.Professional testing institutions.
If the above two methods cannot determine the presence or content of formaldehyde, you can ask a professional indoor air testing agency to test. These institutions usually use specialized instruments and equipment to sample and analyze indoor air to obtain accurate formaldehyde content data. There is a fee for a professional testing facility, but it is very necessary for people who live indoors for a long time to get tested regularly.
Second, the method of removing formaldehyde 1Opening windows for ventilation is the simplest and most direct way to remove formaldehyde. Through the convection of air, formaldehyde in the room can be diluted and discharged outside. It is recommended to open the windows regularly every day after the renovation is completed, especially if the weather is clear and the air quality is good. For newly renovated houses, ventilation is required for at least half a year before moving in. 2.Using activated carbonActivated carbon is an adsorbent that can adsorb harmful substances such as formaldehyde in the air. Placing activated carbon in all corners of the room, such as wardrobes, drawers, under beds, etc., can effectively remove indoor formaldehyde. It should be noted that activated carbon needs to be replaced regularly to ensure its adsorption effect. 3.There are some formaldehyde removal sprays on the market, which can be attached to the surface of furniture by spraying, so as to decompose harmful substances such as formaldehyde. The effectiveness of these sprays varies depending on the brand and ingredients, and you need to choose the right product for you according to the actual situation. At the same time, it is necessary to pay attention to the use method to avoid causing damage to the furniture. 4.Plants purify the airSome plants have the effect of absorbing harmful substances such as formaldehyde, such as spider plant, pothos, aloe vera, etc. Placing these plants in your home can help to purify the air. However, it should be noted that the purification effect of plants is limited, and it cannot be completely relied on to remove formaldehyde from plants. Formaldehyde
