How do you remove formaldehyde in a new house? How to remove formaldehyde in a new house?

Open windows and ventilation is the most common way to remove formaldehyde, we open the doors and windows of the home, so that indoor and outdoor air circulation, but it takes longer to open the window to ventilate and remove formaldehyde, usually we need to ventilate the house for half a year or even more than a year. We also need to pay attention to the skills of opening windows for ventilation, so as to avoid problems such as wall cracking due to non-standard ventilation.

Many plants have the effect of adsorbing formaldehyde and purifying the air, such as spider plant, cactus, monstera and so on. However, plants have limited ability to adsorb formaldehyde. If the indoor formaldehyde level is too high, it can lead to food death.

Under normal circumstances, when we finish decorating the new house, we can not move in immediately, we need to place the new house for about 2 or 3 months before moving in, and during this period, we need to ensure indoor air circulation, which can effectively remove indoor formaldehyde.

You can also put green plants indoors, or put some activated carbon, which can improve the indoor environment and absorb formaldehyde or benzene compounds in the air.

In the newly renovated house, there are some harmful substances, if it is a long-term residence, it is easy to cause damage to the respiratory tract, and it is easy to suffer from leukemia, infertility and other diseases, therefore, after the house is renovated, it needs to be ventilated for 2 to 3 months.

New decoration formaldehyde removal method

After filling a bowl or bucket with cold water, add vinegar or green onions to ventilate the room and open the cabinet door. In this way, the amount of water can be evaporated to protect the surface of the upper coating and residual odors can be absorbed.

After quickly removing the residual paint smell, moisten with a cotton ball with citric acid, and then put the inside and wooden furniture, but it is too troublesome. Many people use tropical fruits to eliminate odors, which are not only effective but also economical and easy to use. For example:

Grapefruit or yuzu peel, these are odorous chemicals that can remove newly renovated homes and have a remarkable effect.

Plant greenery. Studies have shown that saxifera and spider plants can absorb more than 80% of the harsh gases in a room. Aloe vera is also good at absorbing formaldehyde**, it can absorb 90% of formaldehyde in cubic meters of air.

Place some suitable flowers and plants that can not only absorb formaldehyde, but also release oxygen, such as: gerbera, ivy, spider plant, cactus, etc.

Of course, there are green radishes that are especially suitable for food. After the renovation of the house, go to the location of the new house, master bedroom, second bedroom, living room, kitchen and other places. These plants also have a relatively high survival rate, remember to water them often.

Once the renovation is complete, you can buy some activated carbon. Activated carbon has a good adsorption effect and can absorb formaldehyde gas that exceeds the standard of new houses.

Wrap the prepared activated charcoal in cabinets, balconies, TV stands, and other visible places. After ten and a half days, you'll notice that the smell in your new house isn't as strong. window ventilation mode.

This is the most traditional way to get rid of odors, but when opening doors and windows, pay attention to the time and method; Otherwise, the walls will crack and affect the decorative effect. Put a few basins of water in the room, because formaldehyde can be dissolved in water, slice shallots, and put them in all corners of the house, which can also effectively remove formaldehyde; Of course, there are green radishes that are especially suitable for food. After the renovation of the house, go to the location of the new house, master bedroom, second bedroom, living room, kitchen and other places.

These plants also have a relatively high survival rate, remember to water them often.

Activated carbon can adsorb part of the formaldehyde in the new house, but there is a small part of the risk when used, once the adsorption is saturated, it is likely to cause secondary pollution, and there are many tricks to remove formaldehyde in the new house

1. Wise Stone.

It is currently a relatively cost-effective formaldehyde removal product, its advantage is that it can be decomposed into water and carbon dioxide harmless substances to the human body when absorbing formaldehyde, because of its decomposition characteristics, so that it will not appear adsorption saturation and indoor secondary pollution, and suitable for various types of environmental use. In addition, its removal rate is also dozens of times that of traditional adsorbent materials. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Wind fan.

The fan can play the role of "inducing air" to accelerate the discharge of the gas containing free formaldehyde in the room to the outdoors, this method is only useful for the house with poor ventilation, and has little effect on the house with good ventilation effect.

3. Plants.

Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air.

Fourth, the fresh air system.

The fresh air system can introduce fresh air outside and discharge harmful substances from the indoor space through the system's filtration device during the period when the windows cannot be opened, which will reduce the concentration of free organic pollutants in the indoor space to a certain extent and speed up the release of pollutants. Through continuous circulation, the indoor decoration pollution is controlled.

5. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Three stinkers have competed against Zhuge Liang, and formaldehyde is the same, and several methods are recommended to be combined to stabilize formaldehyde in a safe range more quickly.

Dear, first of all, GB18883-2002 stipulates: close doors and windows for 12 hours; Detected by phenol reagent method; The concentration of formaldehyde in indoor air should be less than. These three points should be noted, the lack of one is not accurate, not closed doors and windows, not in line with our actual living habits, you use the detector does not know what it is, and there is no value.

According to the actual situation, it is very likely that the formaldehyde exceeds the standard after decoration, and it is generally recommended to dry it for at least half a year, and then do a professional indoor air quality test before moving in.

If you are not in a hurry to move in now, ventilate it for a while and do a professional indoor air quality before moving in. I don't think your current test results can be trusted.

If there are elderly people and children at home, it is recommended to test whether the formaldehyde concentration exceeds the standard after closing the window overnight before deciding whether to move in, because the immunity of the elderly and children will be relatively low.

Here are some ways to remove formaldehyde that we hope will help you.

Salt water in the new house takes advantage of the characteristics of formaldehyde dissolved in water, we can put a few pots of salt water in each room, so that the big pungent smell in the room can be initially absorbed.

2.Indoor ventilation.

Everyone knows that formaldehyde is a volatile substance, so we can take advantage of this and open all the doors and windows in the room to keep the air convection inside and outside the house, so that it will be about the same for about 2 months. However, this method should be careful to remember to close the doors and windows at night to avoid theft.

3.Turn up the indoor temperature.

The volatilization rate of formaldehyde is generally very slow, if we want it to volatilize as soon as possible, we must try to increase the indoor temperature, and we can turn on the air conditioner for an appropriate amount of time to raise the indoor temperature to speed up the volatilization of formaldehyde.

4.Adsorption of activated carbon, etc.

There are a few things we can use that can have strong odor adsorption to improve indoor air quality. At present, the most popular is the most popular activated carbon on the market. Placing about 50g of activated carbon per square meter can play a good role in the adsorption of formaldehyde, but at the same time, attention should be paid to the replacement of activated carbon, which is generally appropriate once every 7-8 months.

Here I also list other things that have the function of adsorbing formaldehyde, you can choose according to your needs: tea water, salt water, grapefruit peel, onion slices, pineapple pieces, white vinegar aromatherapy, etc., coal ash can also remove formaldehyde gas, you can choose to use it.

5.Green.

Plant adsorption is also a good option. After a large number of investigations and studies by scientists, many green plants such as spider plant, cactus, tiger tail orchid, iron tree, chrysanthemum, etc. have a strong ability to absorb formaldehyde. These plants can effectively absorb formaldehyde while decorating the room, which is one of the common methods to remove formaldehyde in new houses.

6.Emerging formaldehyde removal methods.

You can also use some emerging scientific preparations and scientific research products to remove formaldehyde, such as the popular formaldehyde scavengers on the market and the emerging photocatalyst decomposition method, which are effective solutions to the hazards of formaldehyde in new houses.
