Can a humidifier remove formaldehyde?

Many newly renovated houses will not be habitable until half a year or more because the chemicals used in decoration will cause formaldehyde in the air. Nowadays, people pay more attention to green and pollution-free decoration. If they want to enjoy a healthy living environment, they will choose green decoration. Now many people choose air humidifiers to improve the indoor environment. So, can air humidifiers remove formaldehyde?

Properties of formaldehyde: A colorless, soluble, irritating gas that can be absorbed through the respiratory tract, and its aqueous solution "formalin" can be absorbed through the digestive tract.

Formaldehyde hazards: Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, menstrual disorders in women, pregnancy syndrome, reduced physical fitness in newborns, chromosomal abnormalities, and even nasopharyngeal cancer. High concentrations of formaldehyde are toxic to the nervous system, immune system, liver, etc. Formaldehyde also has teratogenic and carcinogenic effects. People who are exposed to formaldehyde for a long time may develop cancer of the nasal cavity, oral cavity, nasopharynx, throat, skin and digestive tract.

Methods to remove formaldehyde:

1. Ventilation method to remove formaldehyde: Through the circulation of indoor 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, and the air cannot circulate between indoor and outdoor spaces. Not only will the formaldehyde content in the indoor air increase, but radon gas will also continue to accumulate and even reach a very high concentration.

2. Activated carbon adsorption method: Activated carbon is internationally recognized as an expert in drug absorption. Activated carbon masks and gas masks all use activated carbon. This product uses the physical effect of activated carbon to deodorize and remove toxins; it does not contain any chemical additives and has no effect on the human body. Placing two to three discs in each room can basically remove all indoor odors within 72 hours. This method can be used for medium and low pollution, or it can be used in combination with other chemical methods to achieve better comprehensive treatment effects.

3. Folk trick: Soak 300 grams of black tea in two basins of water, put it in the room, and open the windows for ventilation. Within 48 hours, the indoor formaldehyde content will drop by more than 90%, and the irritating smell will be basically eliminated.

4. Plant deodorization method: Plant deodorization can be selected for medium and low pollution: Generally, in environments with light and moderate indoor pollution and pollution values ​​below 3 times the national standard, plant purification can achieve better results.

Choose and place plants according to the different functions and size of the room. Generally speaking, it is more appropriate to place two pots of plants 1.5 meters high in a room of about 10 square meters.

5. Chemical method to remove formaldehyde

1. Treatment with sprays and other drugs can easily cause secondary pollution and may damage furniture, while activated carbon is a physical adsorption method, which is very safe, harmless to the human body, and has anti-mildew and anti-corrosion effects on furniture.

2. It advocates one-time removal (experts question, not credible), but the release of toxic gas in the home is a slow process, so if it is removed today, the smell will reappear in a few days, and the price is not low.

3. There are too many products to distinguish. Although many formaldehyde-control products are labeled as "high-tech" and "environmentally friendly", they actually use some inferior chemical synthetic substances. Although these products can eliminate formaldehyde to a certain extent, they may also re-produce other pollutants and cause secondary pollution. Therefore, consumers must be vigilant when purchasing formaldehyde control products. For example, chemical air treatment products are obtained through artificial synthesis, and many of them are aromatic compounds. Almost all aromatic compounds contain benzene ring compounds which have been proven or suspected to be carcinogens. In addition, many chemical products are oxidizing and corrosive, which can easily damage utensils and cause harm to operators and residents. When the coating of closed concealing products ages and the weather becomes hot and humid, the film is easily damaged, and harmful substances such as formaldehyde will be released, becoming a hidden "time bomb" in the home.
