The most obvious feature of activated carbon filter cotton is its high internal structure porosity, which also determines its strong adsorption capacity. The more porosity and more complex structure, the stronger the adsorption capacity, and the better the product quality of the filter element. However, we can't identify it with the naked eye when buying, and from the perspective of material density, the more the internal structure porosity, the smaller its density, and the lighter the weight of the same volume of filter element. Therefore, we can tell by the feel of the hand. The quality of advanced carbon filter products is relatively light.
Therefore, whether you can buy high-quality carbon filter elements has a direct impact on the nutrition and health of everyone's drinking water.
