In recent years, air filters have entered thousands of families due to air pollution, especially with negative ion function. Because it not only solves our current life dilemma, but also slowly improves our physique. But for how to judge the quality of a negative ion air filter, everyone is still embarrassed.
As a source of negative ions, the closer the ion ion filter is, the higher the concentration of ions, and the negative ions have excellent dust-reducing effect. Therefore, the closer the negative ion air filter is, the more severe the sedimentation is, and the part is attached to the wall. The performance is that the wall is black, the farther away from the negative ion air filter, the lighter the situation.
The effect of negative ions on the sedimentation of the dust with smaller particle size is better. This blackening phenomenon indicates that the fine dust in the air is effectively settled, especially purifying indoor PM2.5, eliminating the entry of these dust into the lungs and breathing into the human body. Harm to human health. In the face of this phenomenon, everyone is guilty. It is a good thing to turn black. But the blackening of the room wall is not the practice of killing the enemy one hundred thousand damages. How can we avoid the blackening of the walls?
Although the blackening of the wall affects the appearance, it at least proves that the negative ion product is effective. Experts suggest that the home can be used to change the position of the negative ion air filter or place the machine one meter or more away from the wall, but to ensure good The purification effect is still to be placed in the scope of human activities. It is understood that even the world's leading negative ion technology can only guarantee that the negative ion air filter releases negative ions in the range of 3-4 meters. After a period of use, wipe the negative ion air filter release end with a damp cloth to avoid black wall phenomenon.
