Upgraded PP and Activated Carbon Composite Filter Optimizes Water Purifier Structure

Household desktop water dispensers and small water purification equipment are developing towards lightweight and miniaturization. The traditional split multi-cartridge structure occupies large space and requires cumbersome replacement, failing to meet product iteration needs. The industry accelerates the large-scale production of PP-activated carbon composite cartridges.

Through integrated molding technology, the outer PP melt-blown filter layer and inner activated carbon adsorption layer are closely combined. A single cartridge achieves both particle interception and odor adsorption, replacing two separate traditional cartridges. Manufacturers optimize composite molding technology to solve problems such as loose lamination, water flow short circuit and material falling off, and balance the thickness ratio of double layers to ensure stable water flux and purification effect.

The outer PP layer intercepts large particles to protect the inner carbon layer from blockage, while the inner carbon layer purifies water and improves taste. The integrated cartridge simplifies internal pipelines and fixing structures, reduces equipment volume and assembly costs, and facilitates user replacement. It is widely used in desktop water dispensers and small portable water purification devices.
