Can tea remove formaldehyde?

In fact, tea can generally remove formaldehyde, but the effect is not that good. The best way is to use black tea and open the windows for ventilation. In this way, the effect will be relatively better. It will take about 48 hours for the formaldehyde in your room to completely dissipate, and formaldehyde will not exceed the standard again. You can also plant plants in the room.

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.

2. Ventilation method to remove formaldehyde hazards

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.

3. Local methods to eliminate formaldehyde hazards

Soak 300 grams of black tea in two basins of water, put it into 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 to eliminate formaldehyde hazards

Plant decontamination can be chosen for medium and low pollution: In general, in environments where indoor environmental pollution is light or moderate, and pollution values ​​are below 3 times the national standard, plant purification can achieve relatively good 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 hazards

1. Treatment with drugs such as sprays 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.
