What are the types of water purifier filters?

How about the filter cartridge? This question cannot be generalized and should be analyzed according to your specific situation. Here is a brief introduction to the characteristics of the filter element for your reference.

1. PP filter element, PP filter element is also called PP meltblown filter element, meltblown filter element is made of polypropylene microfiber hot melt entanglement, the filter element fiber randomly forms a three-dimensional microporous structure in space, and the dimensional pore size is distributed in a gradient along the flow direction of the filtrate, integrating surface, deep and precision filtration, which can intercept impurities of different particle sizes. Characteristics of PP cotton filter element: the accuracy range of the filter element, its flux is more than twice that of the peak room filter element of the same accuracy, and different types of end cap joints can be configured to meet the needs of various engineering installations.

2. Wire-wound filter element is made of textile fiber yarn with good filtration performance precision wound on a porous skeleton. ...

The first type, ultrafiltration membrane filter element, the ultrafiltration membrane filter element on the market is generally similar, but basically it is inseparable from activated carbon.

There are two mainstream ultrafiltration membranes, one is the vertical water purifier ultrafiltration membrane, and the main structure is PP cotton.

Activated carbon, ultrafiltration membrane, etc., one is the horizontal water purifier ultrafiltration membrane, which is composed of stainless steel shell with ultrafiltration membrane and KDF (PS: KDF, microbial inhibition device).

The second kind, the energy filter element, the energy filter element will contain some mineral stones, small molecule stones, alkaline balls, magnetos, etc., don't underestimate these miscellaneous stones, they can greatly improve the mineral content in the water, change the pH of the water to adapt to people, so this filter element of the water purifier is also called activated water purifier in the industry.

The third type is called reverse osmosis membranes.

Also called RO membrane, the ** of this filter element is also the most expensive, the water purifier of this filter element has powerful functions that other water purifiers do not have, for example, as long as the water purifier has this reverse osmosis membrane (RO membrane), then it belongs to the reverse osmosis water purifier, which can directly convert tap water into ultrapure water.

Generally speaking, it is better to choose reverse osmosis membrane.

The second floor of the role is clear, I will not repeat, the key is that the service life or service life of these filter elements is not the same, according to the local water quality and water consumption, according to the specified period of regular replacement, otherwise it is harmful to the body. For example, post-activated carbon should be replaced every six months to a year according to the amount of water consumed.

If you install a water purifier at home, it is important to choose a filter element. What are the commonly used filter elements for water purifiers? PChouse will take you to find out.

1. PP cotton filter element.

PP cotton is the first-stage filter element in the water purifier, which is used to filter large particulate impurities in the water. The common ones are impurities with a diameter greater than 5 m, such as sediment, suspended solids, etc. If your local water quality is not good, then the PP cotton filter cartridge will be replaced a lot of diligently.

But fortunately, the PP cotton filter cartridge is also very cheap, the retail price is only 10 yuan a piece, and the wholesale price is only 3 yuan a piece.

2. Granular activated carbon filter element.

The granular activated carbon filter element of the water purifier is also an indispensable part of the water purifier, the main raw material of granular carbon is coconut shell activated carbon, and the effect of other charcoal is not as good as that of coconut shell, of course, there are some small manufacturers on the market now that the granular charcoal used by some small manufacturers is ordinary charcoal and coal, and consumers can not see the difference, but the effect of filtering water is not so good.

3. KDF compressed activated carbon.

KDF is actually a small ball of copper-zinc alloy, after it comes into contact with water, it can make copper as the positive electrode and zinc as the negative electrode, so as to achieve the effect of adsorption of heavy metals, KDF has a longer service life than activated carbon, and at the same time, it can be washed out and removed from some of the impurities adsorbed on its surface through the flushing function of the water purifier, so as to achieve the role of changing the filter element for several years, saving user costs.
