What are the factors that affect the service life of the filter element of the water purifier?

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 purification capacity of the water purifier depends to a large extent on the quality of the water purification filter, so when purchasing the water purification filter, you must not be too concerned about the product, and ignore the quality of the filter element.

What are the factors that affect the life of a filter?

1. The type of filter element.

At present, there are many types of household water purifier filter elements, such as PP cotton, activated carbon, RO membrane, etc., we should choose according to our own needs and local water quality when buying household water purifiers. However, the replacement cycle of different types of water purifier filters is different, generally between 3 months and 3 years.

2. Water quality.

The water quality of different water sources and different areas is different for the service life of the water purifier filter element, and the water quality in some places is very good, so that the replacement cycle of the filter element will be relatively extended, and on the contrary, if the water quality in the place where you live is very poor, then you may need to replace the water purifier filter element more frequently to ensure the health of your drinking water.

3. Intensity of use.

No matter what kind of water purifier you use, the frequency of use is one of the most important indicators to determine how often to replace the filter. It is important to know that there is a limit to the filtration capacity of any filter. When a filter element reaches the saturation point, it must be replaced, which is even more important for water purifiers without sewage outlets, otherwise, the water flowing out of the water purifier will even be polluted twice, which is not as good as tap water.

Therefore, the water purifier with high intensity (frequency) needs to be replaced regularly.

4. Product quality.

High-quality filters typically take much longer to change than low-quality products. In recent years, the higher profits of household water purifiers have attracted many manufacturers to put into production, which has also led to the uneven quality of household water purifier products from one side. Some manufacturers put more energy into hyping up the concept when producing and selling water purifiers, but the actual purification effect is very limited.

In order to reduce the production cost of the water purifier host and filter element, some manufacturers use relatively low-cost materials, so the quality of their water purification cannot be guaranteed, and the service life of such a filter element will be much shorter, and it is more likely to be polluted twice, which is more dangerous for people to drink.

Lanze intelligent RO water purifier, imported with original and special filter element, has the functions of intelligent monitoring of water quality, filter element replacement reminder, and ultraviolet sterilization.

The life of the water purifier filter element is generally 3-6 months, the activated carbon filter element is 6-12 months, the RO reverse osmosis membrane is 1-2 years, and the ultrafiltration membrane is 3-5 years.

There are long-term technology types on the market, and the life of the reverse osmosis core filter element has been extended to 3 years, which is higher than that of the traditional reverse osmosis filter element。The product with "intelligent multi-stage filter element replacement prompt" can also display the service life of filter elements at all levels according to the actual use of users, and actively prompt users to replace filter elements in stages, which not only ensures water quality safety, but also avoids waste caused by early replacement.

Consumers should not believe the exaggeration and false propaganda of merchants. According to the regulations of the Ministry of Health, the water purifier is not allowed to add functional materials, nor is it allowed to advertise other functions other than the effect of water purification, and it is not allowed to advertise the efficacy of any ** disease. Therefore, consumers should not believe it when they see such a claim, and they must choose a water purifier that has been approved by the national health department for listing.

Pay attention to the following matters when purchasing and using a water purifier:

Choose the type of water purifier. At present, there are several kinds of water purifiers on the market: microfiltration, ultrafiltration and reverse osmosis, among which the reverse osmosis water purifier has the best filtration effect, which can really filter out heavy metals and make drinking water safer. In addition to filtering out bacteria, viruses, residual chlorine, impurities, etc., the reverse osmosis water purifier also rejects harmful heavy metals such as lead and mercury, which better relieves the worries of drinking water and adds a protective net for the health of consumers, especially children.

Filters are the most critical. It is best to buy a water purifier with the function of "intelligent multi-stage filter element replacement prompt". It can bring long-lasting quality drinking water and safety assurance.

As the core component of the water purifier, the state of the reverse osmosis filter element directly affects the quality of the effluent, so regular replacement is essential. In order to ensure the water purification effect and prevent secondary pollution, the water purifier should replace the filter element on time according to the rated total water purification volume.

The above content reference: People's Daily - The filter element of the water purifier needs to be replaced regularly.

The service life of the filter element is shown in the figure below.

It should be noted that due to the different process and structure, the service life of the filter element is also different, in addition to the above common water purifier filter element, the replacement time of other water purifier filter elements is summarized as follows:

KDF (Copper-Zinc Alloy) Cartridge: 2 to 3 years.

Ceramic filter element: half a year to 1 year.

Resin filter element: half a year to 1 year.

Negative ion energy ball filter element: half a year to 1 year;

Far infrared mineralization ball filter: about 1 year;

Granule fine-washed coconut shell activated carbon filter element: half a year to 1 year;

Bulk Sintered Activated Carbon (CTO) Cartridge: Half a year to 1 year;

Maifan stone (tourmaline) filter element: half a year to 1 year;

Note: The water quality, water consumption, and climate in different regions are different, and the replacement cycle is also different.

The life of the water purifier filter element is determined by the material of the water purifier.

Under normal circumstances, PP cotton is replaced once every 3-6 months; Carbon is replaced every 6-12 months; The ultrafiltration membrane is replaced once a year; The reverse osmosis membrane is replaced every 2-3 years.

How long does a water purifier last?

The service life of the water purifier is generally 5-10 years, but it also depends on the user's frequency of use and maintenance, the net replacement cycle of the filter element is different, generally speaking, the service life of the PP cotton filter element is about 3 6 months, the service life of the activated carbon filter element is 6 12 months, the service life of the folded PP cotton filter element is 12 18 months, the service life of the ultrafiltration membrane is 1 2 years, and the service life of the ordinary reverse osmosis membrane is 2 3 years. Angel's composite filter element 12 18 months after upgrading activated carbon and PP cotton, and the long-term reverse osmosis membrane launched can have a service life of up to 5 years.

1. Do not move after installation.

Some users will move the device at will when using the product, which can easily cause the water purifier to not produce water. The accessories in the water purifier are all linked through the connector, and if you move frequently, it is easy to damage the accessories and affect the use function.

2. Replace the filter element regularly.

The water purifier is purified through multiple filter elements, and the service life of the filter elements of different materials is different, so the service life is generally about 3-12 months, but there will be longer filter elements. The water is getting more and more turbid when used at ordinary times, and there is no result in cleaning the filter element, which means that the filter element needs to be replaced.

3. The working environment is suitable.

The installation position of the water purifier should ensure environmental hygiene, and do not be exposed to direct sunlight to avoid heat sources. Water purifiers all have their own working parameters, such as water temperature, water pressure, and water quality. Before use, we must understand the working parameters of our installation equipment, if the water pressure does not meet, you need to install (increase) and reduce the pressure valve, if the water quality does not meet the need to install pre-filtration.

3-5 years. The PP cotton filter element is in use for 3-6 months. The granular activated carbon filter element is half a year to one year.

Compressed activated carbon (CTO) filter cartridges for half a year to one year. The reverse osmosis membrane (RO) filter element is about 3 years. The post-activated carbon (small T33, large T33) filter element is about one year.

Water purification technology different filtration process and filter element have different functional characteristics and service life, water purifier (water purifier) filter element is a consumable, has a certain service life, the actual service life also depends on the local water quality and the frequency and amount of use, replacing the filter element is conducive to prolonging the service life of the water purifier, but also to avoid the secondary pollution of tap water.

The service life of the filter element is related to the water quality, pressure, temperature, and use of pure water in the raw water. Under normal circumstances, the reverse osmosis membrane is changed every two years.

Introduction]:Household water purifier, also known as household water purifier and water purifier, is a water treatment equipment that carries out deep filtration and purification of water quality according to the requirements of water use. The water purifier that we usually talk about generally refers to a small purifier used for home use.

The core of its technology is the filter membrane in the filter element device, and the main technologies are ultrafiltration membrane and RO reverse osmosis membrane.

The water purifier can effectively filter out rust, sand and gravel, colloids in the water, and adsorb residual chlorine, smell, discoloration, pesticides and other chemicals in the water. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water. The application of water purification technology in the field of drinking water makes the phenomenon of "water and soil adaptation" quickly become a thing of the past, and effectively solves the endemic diseases caused by excessive harmful substances in groundwater in many places.

If you use a Wang Liangkong water purifier, you need to pay attention to choosing the best filter element. What are the misunderstandings about the use of water purifier filters? PChouse will take you to find out.

1. The test results of the TDS test pen are qualified and do not need to be replaced.

TDS is only one of the 106 water quality indicators. Many users think that the tap water detected by the TDS test pen is qualified, which is equivalent to the tap water quality reaching the qualified standard. However, in fact, qualified drinking water must meet the comprehensive indicators such as turbidity, total number of colonies, microbial number, heavy metal concentration and other comprehensive indicators to meet the standards.

Second, the filter element does not look dirty and does not need to be replaced.

Some users will be aware of replacing the filter element, but when they remove the filter element, they find that the color of the filter element does not look very dirty, and mistakenly think that it does not need to be replaced. In fact, this practice is inappropriate, and the proportion of substances contained in tap water in different regions is different. For areas with a lot of sediment and rust particles in tap water, the filter will look dirty after a long time.

However, for tap water with a lot of small impurities such as heavy metal ion bond modification and microorganisms, the filter element does not look very dirty after a long time, but the filter element at this time still needs to be replaced.

3. The filter element is not clogged and does not need to be replaced.

Many users have a "one-time" attitude towards water purifiers, as long as the water purifier can produce water normally, there is no need to replace the filter element. In fact, the service life of the filter element needs to consider the two aspects of filtration and adsorption, if there are fewer large particles of impurities in the water, the filter element will not be blocked for several years, but a large number of harmful substances such as heavy metal ions and microorganisms have accumulated on the surface of the filter element.

First of all, we need to understand the role of the water purifier filter. The water purifier filter element is the core component of the water purifier, which is mainly used to remove impurities, odors, heavy metals and other harmful substances in the water to provide safe and healthy drinking water. Common water purifier filter elements include PP cotton filter element, granular activated carbon filter element, compression activated carbon filter element, RO reverse osmosis filter element, etc.

Each cartridge has its own specific filtration function, and the combination of multiple cartridges allows for a more comprehensive removal of contaminants from the water. However, the number of filter cartridges is not the only factor that determines the water purification effect of a water purifier.

In fact, there is no simple linear relationship between the number of filter elements and the effect of water purification. The water purification effect of a water purifier mainly depends on factors such as the type, quality and service life of the filter element. A good water purifier, even with only one high-efficiency filter element, can provide high-quality clean water.

Conversely, if the quality of the filter is not up to par, no amount of filter will guarantee the quality of the purified water. Therefore, when choosing a water purifier, you should pay attention to the quality and performance of the filter element, rather than just the number of filter elements.

In addition, the increase in the number of filter elements also comes with certain maintenance costs. Water purifier filters have a limited lifespan and need to be replaced regularly. The higher the number of filters, the more frequent they will be replaced, which in turn will increase maintenance costs.

Moreover, the ** of the filter element is also expensive, such as the number of denier fruit filter elements is too much, which not only increases the purchase cost, but also increases the maintenance cost in the later stage.

Therefore, the more filter elements of the water purifier are not the better.
