The reason why the water purifier can turn the sewage into clean water is the filter element. It can be said that the quality of a water purifier filter determines the quality of the water filtered by this water purifier. Other solenoid valves and pressure pumps are only an auxiliary function. There are many kinds of filter elements for water purifiers. RO membrane, ultrafiltration membrane, PP cotton and granular charcoal are all included. However, today I don’t talk about this article. I will tell you some basic knowledge of water purifier filter. Do your basic knowledge

 

There are several ways to divide the water purifier filter. The more common ones are classified according to filter material, size, flow rate, or installation method.

 

What we usually see most is according to the division of filter materials, according to the filter material of the water purifier filter, the filter element is divided into PP cotton, granular carbon, compressed activated carbon, and post-loaded silver activated carbon (small taste factor small T33), alkaline Carbon filter, magnetized filter, energy filter, famous RO membrane, ultrafiltration membrane filter, scale inhibitor carbon filter, etc., depending on the function, this needs to look at the local water quality and consumer demand, according to the corresponding design, A variety of filter elements can be made.

 

 

Everyone usually sees more, the first few, the water purifier is used to filter the water after all, the national health department also stipulates that the water purifier can not carry any health care, medicine and other functions during the promotion, those What alkaline water, magnetized water, energy water, etc., should be illegal from the laws of the national health department.

 

The classification method of the second filter element is divided according to the size. The larger the flow rate of the water purifier, the larger the filter element size. The common household water purifier is a 10-inch filter element, and there are also 5 inches, 11 inches. The factory uses 20-inch

 

According to the flow rate, it refers to the reverse osmosis RO membrane filter. The flow rate of RO membranes ranges from 50G to 600G, and the length is usually 10 inches. The size ranges from white wine glasses to 1.5L water bottles in supermarkets. The flow rate represents the amount of water produced in one day. The 50G RO membrane means that this membrane can produce 50G water a day. G means gallon, which is equal to 3.875 liters of water. 50G means that 180L of pure water is produced a day.

 

According to the installation method, the water purifier filter is divided into a filter bottle type filter or a common type filter element, a quick filter element (Korean filter element), a threaded filter element, and a snap-on filter element.

 

 

The water purifier using the filter bottle is usually bulky and takes up a place, and the filter element is flat. The filter cores are all versatile, and they are not subject to the brand of the agent or the water purifier. The filter element has to be replaced. Buying a batch on Taobao to replace it yourself, the replacement cost is relatively low, like other card type filter cartridges, when it is to be replaced. It is not enough to buy other filter elements, and the filter element needs to be dedicated.

 

Some people don't want to buy a filter cartridge, then this ordinary filter cartridge is taken out, washed, brushed, put back, and can be used. This is the benefit of this common filter.

 

The quick-connect filter is also known as the Korean filter, or it is also called the integrated filter. It was introduced from South Korea. It encapsulates the inner core of the filter element in the outer casing and fuses it into one body, which cannot be separated and disassembled, so it is called “integrated filter element”. The whole body including the outer casing and the inner core is disposable, and the replacement is completely discarded, so it is also called "disposable filter".

 

Threaded filter elements and quick-connect filter elements are similar, but the interface is not the same, the cost is not much worse. To say the advantage, the threaded filter element has a slightly larger water flow. There are more threaded filter elements on the commercial water purifier because the flow needs to be larger.

 

 

There is also a snap-on filter element. Among the various filter elements, the snap-on filter element is the most convenient filter element to be installed. Changing the filter element is like replacing a light bulb. Moreover, it is not subject to brand agents. Taobao has ready-made card filters for sale.

 

The disadvantage is that the card filter is the most expensive replacement in several filter cartridges. It is also a disposable filter. The one that is lost when you run out. Suitable for areas with good water quality. If the local water quality is not good, it is recommended to use a filter bottle filter.
