The principle of negative ion in addition to formaldehyde is to turn harmful substances into macromolecules and sink into the ground through the attraction, collision and neutralization of positive and negative ions. Generally, pollutants such as formaldehyde and toluene are positively charged, while negative ions are negatively charged. The collision of positive and negative ions will play a role in thorough removal.
The commonly used activated carbon in addition to formaldehyde is based on the principle of adsorption. After adsorption saturation, activated carbon will release formaldehyde, which cannot be completely removed. Negative ions completely remove formaldehyde, which is also an important reason for purifying the air inside the car.
It is said that the formaldehyde release cycle in the car is as long as 3- 15 years. Formaldehyde has a subtle and serious impact on families and children. For the health of my family, I did not hesitate to buy a poetic dream cushion, which is priceless.
