Methods for removing formaldehyde are:
1. Ventilation method
Through the circulation of indoor air, the content of harmful substances in the indoor air can be reduced, thereby reducing this The harm of substances to the human body. In winter, people often close their doors and windows tightly, and indoor and outdoor air cannot circulate. Not only will the content of formaldehyde in the indoor air increase, but radon will also continue to accumulate, even reaching very high concentrations.
2. Deodorization method
Formaldehyde deodorizer can capture and decompose harmful pollutants such as formaldehyde, benzene and ammonia, kill germs, mites and harmful microorganisms, and purify air to eliminate odors.
3. Activated carbon adsorption
Activated carbon can rely on its own developed pore structure and surface area to be exposed to the surrounding air to a great extent, and passively adsorb some pollutants into its own pores. Therefore it is widely used to remove indoor formaldehyde. Among them, activated carbon made of coconut shell has the best adsorption performance.

Eliminate misunderstandings about formaldehyde
1. Use water, vinegar, and black tea to soak in water to remove formaldehyde
Use water, black tea It is obviously unrealistic to use methods such as vinegar and vinegar to absorb formaldehyde. The release of formaldehyde is closely related to indoor temperature and humidity. As the temperature in the air increases, the amount of formaldehyde released will greatly increase. Experimental results show that when the relative humidity in the air increases by 10%, the amount of indoor formaldehyde released will increase by about 5%.
2. Fruit peels such as oranges and pineapples cannot absorb formaldehyde
Some people believe that fruit peels can eliminate formaldehyde. In fact, this idea is unscientific because grapefruit peels , pineapple, etc. not only cannot remove formaldehyde, but will also increase the indoor formaldehyde content.
