How to remove formaldehyde from newly bought furniture?

Activated carbon adsorption:

Activated carbon to remove formaldehyde is a relatively cheap and practical method, characterized by physical adsorption, thorough adsorption, not easy to cause secondary pollution. The physical effect of activated carbon is deodorization and detoxification; There are no chemical additives and no effect on the human body.

Nanotechnology absorption decomposition:

The method after decoration is to use products with powerful functions of capturing, adsorbing and eliminating formaldehyde. Using high-tech nano and nano modification technology, after multiple screening, formulation and activation modification, several natural nano-scale raw materials are combined with conventional oxidants, which can effectively remove harmful gases such as formaldehyde, ammonia, benzene, carbon monoxide and so on in the indoor environment. Not only for formaldehyde, but also for ammonia, benzene, TOVC and other harmful substances can be effectively removed.

This method can be used for a moderate excess of 30 square meters.

Ventilation method to remove formaldehyde:

Through the circulation of indoor and outdoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, indoor and outdoor air can not circulate, not only the content of formaldehyde in indoor air will increase, radon will also continue to accumulate, and even reach a high concentration.

Soil trick: 300 grams of black tea to make hot tea in two basins of water, put it in the living room, and open the window for ventilation, the indoor formaldehyde content will drop by more than 90% within 48 hours, and the irritating odor will be basically eliminated.

Plant deodorization:

Plant decontamination can be selected for medium and low pollution: general indoor environmental pollution in the environment with light and moderate pollution, and the pollution value is less than 3 times the national standard, and the use of plant purification can achieve better results. Choose and place plants according to the different functions and sizes of the room.

In general, in a room of about 10 square meters, it is more appropriate to put two pots of plants with a height of meters. (Recommended indoor pollution control methods: ventilation + activated carbon + formaldehyde removal plants, suitable for medium and low pollution).

Choose and place plants according to the different functions and sizes of the room. In general, in a room of about 10 square meters, it is more appropriate to put two pots of plants with a height of meters.

1. Ventilation method.

The best thing to do is to ventilate.

2. Plant absorption method.

Plants have a strong ability to absorb formaldehyde, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better effect on absorbing formaldehyde, such as spider plant, tiger tail orchid, etc.

3. Methods of folk circulation.

Place tea pomace, grapefruit peel, onion slices, pineapple chunks, etc. in the newly renovated room or fumigate the whole room with white vinegar.

4. Activated carbon adsorption method.

Solid activated carbon has the characteristics of many pores, and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde, and the smaller the particles of activated carbon, the better the adsorption effect.

5. Photocatalyst decomposition method.

Under the stimulation of light, the catalyst in the photocatalyst generates negative ions and hydrogen and oxygen radicals with oxygen and water in the air, which can oxidize and decompose various organic pollutants and inorganic pollutants, and finally degrade into harmless substances such as carbon dioxide, water and corresponding acids, so as to decompose pollutants and purify the air.

6. Chemical purification method.

At present, there are two types of formaldehyde scavengers on the market, one is to purify the air by neutralizing formaldehyde and generating harmless substances; The other is to purify the air by sealing formaldehyde and preventing the volatilization of formaldehyde.
