How can I identify formaldehyde indoors?

A method to detect whether formaldehyde exceeds the standard by yourself.

1.Sensory method, both after the decoration is fully ventilated for 7-15 days, close the doors and windows for 24 hours, and then enter the room, if it feels dazzling or pungent, then your indoor formaldehyde is likely to exceed the standard by more than 4 times. (If only the furniture is harsh or pungent in the room, then the formaldehyde in your indoor space may also exceed the standard by about two times).

2.Calculation, according to how many plates are shared in your decoration? The surface area of the purchased furniture is multiplied by the formaldehyde test index in the relevant information provided to you by the manufacturer.

Then divide it by the volume of space in your entire room, which is the saleable area multiplied by the height from the floor to the ceiling. (Since the credibility of the manufacturer's data is almost zero, the practical value of this method is limited).

3. Self-purchased testing agent, there are many self-testing formaldehyde testing agents on the market for sale, if you choose this way to detect, it is recommended that you first mix those things together according to the instructions before using them to observe whether they are discolored? (This product is basically in two sets, so you can just take one out and try it.) If there is no discoloration or it is within the standard, you can also try it, generally that kind of product is a 6-hour average, that is, after 6 hours of colorimetry.

Do not place the sample utensils in furniture. Hopefully, you can place it in the center of your room, at a height of meters. If you wait for 6 hours to compare the color, if you find that the color is not within the color scale provided by the product, the results of this reagent are not very trustworthy.

As long as there is furniture, as long as there are plastic products, there is formaldehyde, only if the concentration does not exceed the standard, it will not affect health. If you feel that the smell is strong, you should always open the window for ventilation or replace something that smells particularly strong. Hope.

The most accurate way to judge indoor air quality is naturally instrumental measurement. At present, the available tools for measuring formaldehyde on the market, one is the formaldehyde self-test box, the other is the handheld formaldehyde detector, and the other is to ask a professional testing institution to do formaldehyde testing.

In fact, the pungent smell in the decoration process is not only formaldehyde, it will be taken away in the process of opening the window for ventilation, and the incubation period of formaldehyde is as long as 3-15 years, and after other odors dissipate, formaldehyde is actually still slowly released, and the smell is basically not smelled below 4 times the standard, that is to say, only more than 4 times the standard can have obvious odor, and it is too late to treat it at this time.

If you want to quickly know whether the indoor formaldehyde exceeds the standard, the simplest and rude way is to find a professional formaldehyde removal company, they have a set of professional testing equipment, which can let the owner know whether the indoor formaldehyde exceeds the standard by detecting the indoor formaldehyde content.

If you want to identify whether there is formaldehyde at home, it is very simple, as long as you find a professional formaldehyde testing agency or formaldehyde test box to check it, you will know that removing formaldehyde is a major problem after many home decorations, and everyone will search on the Internet to see what good methods can be used for reference, but there are many unscientific methods to remove formaldehyde, which not only delays the time to move in, but also increases the difficulty of removing formaldehyde.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde absorbed by it is very limited, and when the indoor concentration is high, if the plant simply relies on the adsorption of formaldehyde, its dosage is very large.

3. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated.

5. Ventilation is an indispensable method for removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution.

6. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying

Indoors, especially the newly renovated house will have formaldehyde, the newly renovated house will have a large formaldehyde content, causing great harm to the human body, so in order to ensure a healthy life and residence, how to judge whether there is formaldehyde in the room?

1. Olfactory judgment.

Formaldehyde is a colorless and odorless harmful gas, the simplest and most direct way is to judge through people's sense of smell, there are special circumstances, if the formaldehyde content in the space is not very high, if it is not accurate to feel through the sense of smell, it will feel a pungent taste when the formaldehyde concentration is high.

2. Formaldehyde detector.

Formaldehyde detector is a kind of chemical reaction to detect the formaldehyde content in the air, such formaldehyde detection products are certified to be able to effectively detect formaldehyde, and will also be affected by some external factors in the detection process, grasp the time during the detection to ensure the accuracy of formaldehyde detection.

3. Formaldehyde testing company.

Now there are many professional formaldehyde testing companies, they use some professional technology to detect indoor formaldehyde, they are from the site to collect air, using professional formaldehyde detection tools and methods to judge the content of formaldehyde. Before hiring a company, be sure to understand its business, such as showing some reports, some case records, and some professional tools before making judgments.

Self-judgment of whether indoor formaldehyde exceeds the standard, these three phenomena tell you!

Here are a few ways to detect formaldehyde in the room:

1.Formaldehyde detector: There are a variety of formaldehyde detection instruments on the market, which can be purchased by yourself or with the help of professional institutions for indoor air testing. When using, it should be operated in accordance with the specifications of the manual, and pay attention to the safety issues during use.

2.Smell: Formaldehyde usually releases a pungent odor, and if you feel a significant odor in the room and it persists, it may be caused by excessive formaldehyde.

However, different people's sensitivity and judgment of odor are also different, and the smell cannot be affirmed by the presence of formaldehyde and other polluting substances, let alone accurately judge its concentration and level.

3.Eutrophic water plants: Some environmentally friendly plants rich in adsorption of harmful gases such as erector formaldehyde, such as aloe vera, spider plant, tiger tail orchid, etc., can be used to purify indoor air;

4.Precautionary measures: most of the new house decoration will use a large number of wood furniture, boards, coatings will also be processed on the wall, floor and ceiling and other places to accept the key, if you can choose the decoration in line with the environmental protection hole delicate standard of materials, timely open windows and ventilation and other ways can reduce indoor formaldehyde pollutant emissions.

If you suspect that indoor formaldehyde exceeds the standard or there are other indoor air pollution problems, it is recommended to seek help from professional institutions to ensure the safety of the living environment.

You can choose green materials, indoor testing instruments and human senses before decoration to understand whether formaldehyde exists in the room.

1.Choose green materials: Choosing green materials before decoration can effectively reduce the possibility of indoor formaldehyde content. When purchasing, you can pay attention to choosing a brand with complete environmental protection marks and authoritative certification, and check whether the product manual meets the environmental protection requirements.

2.Indoor testing instruments: You can buy indoor formaldehyde testing instruments for testing, if you don't know how to use them, you can find professionals or testing institutions for testing.

3.Human senses: People will feel discomfort in the eyes, throat, nose and other discomfort in the room with high formaldehyde content, but this cover is only suitable for a certain amount of formaldehyde, and more than a certain amount of human senses will be adapted, and it is difficult to find.

Summary: To understand whether there is formaldehyde in the room, you need to buy green materials from the decoration, self-test with tools or find a professional testing agency for testing. In normal times, it is necessary to pay more attention to the changes in the human senses and open the windows for ventilation in time.

Expansion: After decoration, if there is a heavy odor or itchy eyes and other discomforts in the room, you can open the windows indoors for ventilation and pay attention to keeping the environment dry. Excessive pollution hangs an indoor air purifier that removes formaldehyde, but it is recommended to keep indoor natural things as good as possible, and the purifier only plays an auxiliary role in the process.

How to know if there is formaldehyde in the room

The first method is the self-experience method. The so-called self-experience method is actually a rough test method, and it cannot specifically estimate the specific concentration of formaldehyde. To put it simply, it depends on the reaction of yourself and your family, whether your immunity is reduced, or whether there is a noticeable odor when you are close to a piece of furniture.

Of course, this method is still relatively primitive. If you feel that formaldehyde exceeds the standard, if you want to make further sure, you still have to ask a professional to test it.

The second method is the physiological response of animals and plants. In fact, the physiological response of animals and plants is also a relatively rough test. For example, in real life, after we move into a new house, if the animals raised at home suddenly do not eat often, and they are not as active as before, and their immunity is reduced.

Or the plants in the house begin to slowly wither and die, these are all manifestations of excessive formaldehyde. When this happens, be sure to ask a professional to test it, and then use a certain method to eliminate it.

The third method is the formaldehyde self-test box. In fact, the formaldehyde self-test box is also a relatively simple way to detect formaldehyde. Generally speaking, before we want to ask a professional indoor environmental protection company to conduct testing, we can also buy a formaldehyde self-test box for testing first.

If it is found that the formaldehyde has an excessive fraction, you can ask the indoor environmental protection company to conduct further testing.

The fourth way is to ask a professional company to do the test. In fact, this method is also the most accurate method, after all, it is to do this business, professional companies will of course be very professional, they can detect through their own professional testing equipment, get a specific formaldehyde concentration, and then eliminate it in a targeted manner.

To determine the presence of formaldehyde in a room, the following methods can be taken:

1.Olfaction: Formaldehyde has a pungent odor, and may emit a pungent smell at higher concentrations.

If you can smell a peculiar smell similar to glue or a pungent odor, there may be a problem with formaldehyde. However, low concentrations of formaldehyde may not be noticeable, or other odors may mask the formaldehyde taste.

2.Air quality testing instruments: The use of professional air quality testing instruments can accurately measure the formaldehyde concentration in indoor air. These instruments can detect a wide range of contaminants, including formaldehyde, volatile organic compounds, and more.

Whether there is enough formaldehyde indoors can be judged by the following aspects:

1.Air humidity.

After being left indoors for a period of time, the air humidity can clearly show the formaldehyde concentration in the room. If the air humidity increases significantly, it means that the indoor air humidity is high, and the concentration of formaldehyde will decrease.

2.Temperature.

The lack of indoor temperature also has an effect on formaldehyde concentration. If the indoor temperature is too high, the formaldehyde concentration will rise, while if the temperature is too low, the formaldehyde content will decrease.

3.The smell is hail.

Formaldehyde is a colorless and odorless gas, so odor is also important. If a pungent odor is smelled indoors, then the formaldehyde concentration may increase.

In short, formaldehyde is a common indoor pollutant, and it is necessary to pay attention to keeping the indoor air clean and hygienic in the process of indoor decoration, furniture use, ventilation, etc.

You can buy formaldehyde reagents online, or find a professional to measure them.
