How to detect and control indoor formaldehyde?

After a house is newly renovated, it will cause pollution to the room. Indoor decoration materials will produce formaldehyde and other gases that are harmful to the human body. The smell is particularly unpleasant and affects human health. Therefore, you cannot move in immediately after the decoration. You must wait until the formaldehyde in the room is released before you can move in. Many people do not know how to detect whether there is formaldehyde in the room. How to detect and control indoor formaldehyde? Let’s take a look at it next.

1. Smell

Formaldehyde is a colorless gas with a pungent odor. If there is a strong, pungent, and unpleasant odor in the room after decoration, it means that the indoor formaldehyde level must exceed the standard. However, it cannot be said that if there is no odor, there is no formaldehyde, and the formaldehyde content does not exceed the standard, because formaldehyde volatilization time is relatively long, which can be as long as 3-15 years.

2. See the reactions of plants and animals

If a large number of indoor plants wither or become sick, or pets become sick after you move into a new home, it means that the formaldehyde content in the room is above the standard.

3. Self-test method

After moving into a new home, if your family and yourself have weaker immunity than before, and are always sick, crying, coughing, dizzy, etc., it means that the formaldehyde content in the room is above the standard.

4. Use a formaldehyde detection kit

This method is the most economical and very safe method. It is relatively simple and convenient to use. It is best to use a formaldehyde detection kit to test before moving in. If the formaldehyde exceeds the standard, do not move in first. After all, health is the most important thing.

5. Use a formaldehyde detector

If conditions permit, you can buy a formaldehyde detector to test the formaldehyde in the room. The results measured by the formaldehyde detector will be more accurate, but it is expensive. If you buy a cheap one, the test results will not be very accurate. If you want to buy one, you should buy a similar one.

6. How to control formaldehyde

1. Open windows for ventilation

Whether it is a newly renovated house or a house that has been renovated for a long time, you must open the windows frequently for ventilation to keep the indoor air circulating so that harmful gases such as formaldehyde can be quickly dissipated.

2. Plant cultivation

Grow more plants indoors. Plants can purify the air. Plants like spider plants, green ivy, aloe vera, etc. also have a certain effect on absorbing formaldehyde. The raw materials of many formaldehyde removal products are also extracted from these plants. Plants can not only absorb formaldehyde but also have high ornamental value. It can be said to kill two birds with one stone.

3. Activated carbon solids

Activated carbon is easy to use, can be placed anywhere, and is not expensive, so it is favored by many people. Activated carbon mainly utilizes a large number of adsorption pores to adsorb harmful gases such as formaldehyde. However, the disadvantage of activated carbon is that it is relatively easy to saturate. If it is not cleaned regularly, at a certain temperature, the formaldehyde molecules adsorbed by the activated carbon will be emitted again, causing secondary pollution.

4. Photocatalyst to remove formaldehyde

Photocatalyst is one of the more common methods of removing formaldehyde and purifying the air, and it is also one of the methods that shows results more quickly. There are many types of photocatalysts, including photocatalyst wood essential oil, leather formaldehyde removal care solution, etc., which are used for different purposes. The principle of photocatalyst is mainly to decompose harmful substances such as formaldehyde in the air into harmless substances such as carbon dioxide through the effect of light. It can not only remove formaldehyde and purify the air, but also form a layer of photocatalyst protective film on the surface of objects, and the effect can be seen quickly.

5. Place fruits or fruit leather

If there is a strong odor in the room that is difficult to remove, you can put some fruits or fruit peels, such as orange and grapefruit peels, in every corner of the room. The fragrance of the fruit will cover up other unpleasant odors. However, this method has no effect on removing formaldehyde.
