In the filter element of a water purifier, there is an indispensable type of filter element that is cheap, stable in performance, and usually the forefront of water treatment, which is the PP cotton filter element. The raw material of PP cotton filter cartridge is non-toxic and odorless polypropylene particles, which are heated, melted, spun, pulled, and shaped. If the main raw material is polypropylene, it can also be called polypropylene spray filter cartridge. Now let's take a look at its capabilities.

Firstly, the chemical stability of PP cotton is very good. Apart from being corroded by concentrated sulfuric acid and nitric acid, it does not undergo any chemical reactions with other chemical agents. Therefore, it can resist acid, alkali, organic solvents, and oils, without worrying about its own secondary pollution problems.

The second is that during the processing, the bonding of PP cotton filter cartridges does not require the use of other materials, relying on their own bonding and entanglement to form various sizes of filter cartridges, without the risk of contamination by other raw materials.

The third is the formation of a three-dimensional meandering microporous structure during the self bonding process, which has a large specific surface area and higher porosity. This allows the PP cotton filter to hold a large amount of dirt, while also allowing water to pass through relatively quickly without the need for additional boosting devices. This also means that the PP cotton filter does not require power boosting.

The fourth multi-layer filtration structure can intercept and store impurities in water at each layer. The outer fibers are thicker, the inner fibers are thinner, the outer layer is looser, and the inner layer is tighter, forming a multi-layered gradient structure. This multi-layer structure will have a large amount of dirt absorption, and 80% of the impurities filtered out by the water purifier are completed in the PP cotton filter element.

The service life of PP cotton filter is usually 3-6 months, depending on the usage and quality of tap water, but it must be replaced regularly to ensure the water purification effect
