You have to know several kinds of water filtration media

Many consumers don't know much about the knowledge of water purifier products. There are many questions in the process of purchasing and using water purifiers. In fact, the principle of water purifier is very simple, and the key lies in the core components - filter elements. So what are the water filtration media of the water filter elements, and what are the characteristics?

1, PP
The PP filter element is also called PP melt-blown filter element. The melt-blown filter element is made of polypropylene microfiber hot-melt entanglement. The water filtration media fiber randomly forms a three-dimensional microporous structure in space, and the pore size of the pores is distributed along the flow direction of the filtrate, and the surface, deep layer, Fine filtration in one, can intercept impurities of different particle sizes.
2, Activated carbon 
There are two main types of activated carbon filter products: compressed activated carbon filter and bulk activated carbon filter.
The compressed activated carbon filter cartridge uses a high adsorption value of coal-based activated carbon and coconut shell activated carbon as a filter material, and is sintered and formed by a food-grade binder.
The bulk activated carbon filter inserts the required activated carbon granules into a special plastic casing, and the end caps are welded to both end faces of the casing by welding equipment.
3, Ceramic 
The ceramic filter element is a new environmentally friendly filter element, which uses diatomite mud as raw material. Its average pore size is only 0.1μm, which is the filter element with the highest filtration precision.
The purpose of the ceramic water filtration media  is to remove the liquid medicine in the water, the plating solution, and the solid particles in the tap water, and the carbon filter core removes the organic impurities in the liquid.
4, Resin  (for water softener)
The resin is a porous, insoluble exchange material. The resin filter in the water softener contains a lot of fine resin balls (beads), and all the balls contain many negative charge exchange positions for absorbing positive ions. It is commonly used as a water softener filter and can pass a resin regenerant (soft water salt) after filtration.
5, KDF filter material
KDF is a high-purity copper alloy that can perfectly remove heavy metals and acid ions in water, improve the activation degree of water, and is more conducive to human body's absorption of water, protect human health and promote human metabolism.
6,Hollow fiber ultrafiltration membrane
The hollow fiber ultrafiltration membrane is a type of ultrafiltration membrane. It is the most mature and advanced technology in ultrafiltration technology. Ultrafiltration membrane is one of the earliest developed polymer separation membranes.
7, RO reverse osmosis membrane (usually used in pure water machine)
RO reverse osmosis membrane, RO is the abbreviation of English Reverse Osmosis membrane. Chinese means: reverse osmosis (reverse osmosis). Generally, the flow of water is from low concentration to high concentration. Once the water is pressurized, it will flow from high concentration to low concentration. , the so-called reverse osmosis principle.
There are many types of water purifier filter cartridges. Different water purifier filter cartridges have different functions. The most common ones are activated carbon, PP cotton filter, RO reverse osmosis membrane and KDF alloy filter.
