The filter element of the water purifier is problematic, and the filter element is reminded to chang

A water purifier that does not need to replace the filter element is not a qualified water purifier Now all the filter elements on the market, including the filter material, have a lifespan, because the filter element will produce secondary pollution after it is permanent, and it must be replaced. How could the manufacturer advertise like this.

You mean disposable closed filters and open filters, right?

In fact, they all need to be replaced, the closed ones are generally replaced within 1 and a half years, and the open ones are generally replaced once every 2-3 months, but the closed ones are more expensive, the open ones are cheaper, and the closed ones are basically foreign brands, and the open ones are mostly domestic.

The closed integral filter element is just a concentrated PP cotton activated carbon permeable membrane. The open is the larger volume, in fact, the principle is basically the same.

There is really no water purifier that does not replace the filter element.

It's only a matter of time.

The longest time should be the ultrafiltration water purifier, the replacement time is 3-5 years, because the customer can discharge the sewage every day, which prolongs the service life of the filter element and ensures the quality of the water from the water purifier.

It is impossible for a water purifier to last a long time. At most, it is only three years, and the ultrafiltration membrane water purifier has a sewage outlet to discharge sewage, which is generally only replaced once every three years. Purified water flows out of the water purification port.

The cost of the water purifier that changes the filter element frequently is relatively high and very troublesome, generally if the filter element is changed once every 3 to 6 months, there will be expenses for each element change. There are tens to hundreds of dollars.

There is no water purifier in the world that does not change the filter element.

The best filter element is reverse osmosis.

The filter element is a consumable, such as the ink cartridge in the printer, which has to be replaced after a long time.

The filter element must be replaced, and the poor quality will have to be replaced for half a year, and it will take several years to replace.

I think it's better to replace the water purifier with the filter element.

It is good not to change the filter element, because this involves the trouble of life, the filter element** and a lot of after-sales problems, those water purification equipment that does not change the filter element, in fact, do not need to consider the impurities in the water, each equipment will have a rated water purification, just consider it, and then look at the product inspection ** single import and export list and the product market can be compared Personal suggestion Paisi water purification It is a very popular equipment in the United States for more than 80 years, if it is not good, it will not stand for so long.

You're talking about domestic brands, right? The domestic ones have to change the filter element. Because it's a physical method. Some foreign brands do not need it, it uses a chemical-like method. It is more advanced than the domestic one.

Of course, it is good to replace the filter element, and the impurities can never be discharged, only a thorough replacement.

It definitely needs to be changed. There are 4 to 5 levels of filtration in the water purifier, and after a long time, the filter will lose its filtration effect. Resulting in a decline in water quality.

The PP filter element is also called the PP meltblown filter element, and the meltblown filter element is made of polypropylene microfiber hot melt entanglement, and the fibers randomly form a three-dimensional microporous structure in space.

The pore size of the dimensional pore is distributed in a gradient along the flow direction of the filtrate, integrating surface, deep and fine filtration, which can intercept impurities of different particle sizes. 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.

Cartridge Replacement Interval:

With the rise and popularity of the water purifier (water purifier) market, the water purifier (water purifier) has gradually become a must-use household appliance for thousands of households. Nowadays, the water purifier industry is in a period of rapid growth.

There are many brands of water purifiers on the market, and the varieties of water purifiers are also dazzling, and the filtration process and structure of different water purifiers are different, but in general, the vast majority of commonly used water purifier filters are divided into the following types, and how often the filter element of the water purifier is replaced, which is summarized as follows: The name of the water purifier (water purifier) filter element service life.

The water purifier prompts to replace the filter element, which means that you need to replace the filter element of the water purifier for the after-sales service! If you don't replace it in time, it is easy for bacteria to grow if you continue to use the filter, and it is even less effective than drinking tap water directly.

Water purifier filter element replacement cycle:

1. Hollow fiber ultrafiltration membrane (UF) filter element for 3 years or more than 3 years 2. Reverse osmosis membrane (RO) filter element for about 3 years.

3. Granular fine cleaning coconut shell activated carbon filter element for half a year to one year.

4. Block sintered activated carbon (CTO) filter element for half a year to one year 5, PP cotton filter element for 3-6 months.

6. KDF filter element for 2-3 years.

7. Maifan stone (tourmaline) filter element for half a year to one year.

8. Ceramic filter element for half a year to one year 9, far-infrared mineralization ball filter element for about one year 9, post-activated carbon (small T33, large T33) filter element for about one year 10, negative ion energy ball filter element for half a year to one year.

11. Soften the filter element for about half a year.

12. Magnetized filter element for half a year to one year.

13. Silica phosphorus fine filter element for 2---3 years.

14. Quartz sand filter element 1--2 or so.

15. Manganese sand filter element (FF) for half a year to one year.

In short, different filtration processes and filter elements of water purification technology have different functional characteristics and service life, water purifier (water purifier) filter element belongs to consumables, has a certain service life, the actual service life also depends on the local water quality and the frequency and amount of use, frequent flushing is conducive to prolonging the service life of the water purifier filter element.

Since the water purifier is a "lifelong maintenance" product, it needs to continuously replace the filter element to keep it in good working condition and provide qualified purified water, but this is often a hassle for consumers. Not to mention that the disassembly of the filter element requires a certain amount of hands-on ability, just determining when to replace the filter element is also a headache. Because on the product, you don't see any exact tips, it's generally a large range of time periods.

In fact, there is no way to do this, different water quality, different use conditions will lead to different filter replacement cycles, so the manufacturer intelligently provides an approximate cycle. In order to help consumers solve this headache, some manufacturers have added the function of "filter element life prompt" on the product, which is generally an LED display panel, which lists the life progress bar of each filter element, and over time, the progress bar of the filter element will decrease until the alarm sounds. Theoretically speaking, this is a good function, but whether this function can provide accurate replacement information, but it needs to be verified, if the replacement filter reminder it provides is based on unreliable information, then this function is basically a decoration.

The following is a brief description of how the filter life reminder function is usually implemented. 1 Timer.

It's definitely going to change. Filters break easily. Generally, it should be changed once a month.

Yes, it can be replaced within 7-10 days after the reminder.

Summary. Hello, dear. The water quality does not change after the water purifier is replaced, which may be due to the following reasons:1RO membrane blockage. 2.The pre-filter is clogged. 3.Post-activated carbon clogging.

Hello, Lafu dear. The water quality does not change after the water purifier is replaced, which may be due to the following reasons:1RO membrane blockage. 2.The pre-filter excitation ruler core is clogged. 3.The rear active wheel is blocked with lead and carbon.

In addition, after the water purifier was replaced, the water quality still could not meet the standard. It may be that the water quality is too poor and the water purifier can't completely treat it. In this case, you can add a pre-filter to use.

It may also be that the filter element that was replaced after the replacement is not up to standard, so that the water treated by the water purifier will also not meet the standard. Or the wheel girder, you can contact the manufacturer to ask what the situation is.

Water purifier water quality testing method.

Water purifier water quality testing method: 1. Detect the residual chlorine in the water. The water purified by the water purifier can remove the residual chlorine in the water.

If you want to test the water purification effect of the water purifier, you can prepare a residual chlorine tester and use it according to the instructions to know the amount of residual chlorine in the water. It is recommended to prepare two glasses of water, one cup of tap water and one cup of purified water during the test. 2. Detect organic matter in water.

In addition to residual chlorine affecting water quality, there are many substances that affect water quality, such as organic aggregates, heavy metals, etc. You can test it to see if the water purified by the water purifier is clean. Prepare two glasses of water first, one is tap water for one cup of swimming, one cup is water for purification, and then put the aluminum rod and iron rod in the water and turn on the electricity for 1 minute.

You will notice that the color of the water changes, and usually, water with light color is cleaner and water with dark color is dirtier. 3. TDS value detection. There is also a tool on the market to test water quality, the TDS pen, which is easy to use, as long as the tip of the pen is inserted into the water, you can see the value.

The higher the value, the higher the purity of the water. Usually, the TDS value of the filtered water from the water purifier is about 20, if it is too low, it does not meet the standard, and if it is too high, it is not normal. If you want to test the water purification effect of the water purifier, you can buy a TDS pen to try.

When testing water quality, it should be tested in about a week after normal use of the water purifier, so that the data obtained will be more accurate.

1. The water production of the water purifier becomes smaller. Under the same conditions (e.g., the water pressure is the same as the water temperature), the water purifier produces less water. Then it is very likely that the filter element is blocked, if the water purifier filter element is close to its service life, then it is necessary to replace the water purifier with a new filter element.

2. The RO reverse osmosis water purifier makes water too fast. The water purifier has a significant acceleration of water output, which is generally caused by damage to the RO membrane, and a new RO membrane must be replaced, otherwise the water purifier will completely lose its filtration function.

3. The taste of the water from the water purifier is very poor. This situation is because the water purifier filter element filters too many impurities and bacteria, and accumulates at the filter element for too long, resulting in secondary pollution of tap water. Again, this tells the user that the filter needs to be replaced.

The water purifier prompts to replace the filter element, which means that you need to replace the filter element of the water purifier after the sale.

When the traditional water purifier has the following situations, it is time for the filter element of the water purifier to be replaced.

1. Water output.

When the water flow of the water purifier is very small, it is closed or cannot meet the normal needs. It means that the filter element is clogged and the filter element should be cleaned to restore the normal flow rate, or when the flow rate is still small after cleaning and cannot meet people's normal needs.

2. Taste. When the taste of the water purifier decreases and the taste is close to the tap water, that is, the chlorine smell of the tap water cannot be removed, indicating that the activated carbon filter element of the water purifier has been adsorbed and saturated, and the activated carbon fails, at this time, the filter element of the water purifier should be replaced.

3. Service life.

The life of the reverse osmosis filter element of the water purifier is generally about 1 year or 2 years, if the filter element of the water purifier is used for more than two years, the filter element should be replaced in most cases. Moreover, if the frequency of replacing the filter element or the difference between them is a long time, the purification effect of the water purifier will not meet our expected requirements, which is also harmful to the water purifier.

The filter element of the water purifier is a key component of Qingxin to purify water quality, and it generally needs to be replaced during the opening period to ensure the filtration effect. When the filter element inside the water purifier reaches the end of its useful life, there will usually be a beep or indicator light to remind you to replace the filter element early. This is because over time, the material of the filter will gradually saturate, losing its ability to purify the water.

The meaning of replacing the filter element of the water purifier is that the filter element inside Jianxiaoliang is filled with impurities, or it needs to be cleaned after a long time, that is, the filter element should be taken out to clean or replaced!

If one of the following occurs, it's time to replace the filter.

1. The effluent flow is very small and cannot meet the normal needs (indicating that the filter element is blocked, and the filter element should be cleaned in order to restore the normal flow), and the flow rate is still very small after cleaning and cannot meet the needs;

2. The taste of the effluent decreases and the taste is close to that of tap water, that is, the chlorine taste of tap water cannot be removed, indicating that the activated carbon filter element has been adsorbed and saturated, and the activated carbon is invalid;

3. The softening function cannot be restored after the softening core is regenerated or the softening effect does not meet the requirements;

4. The service life of the filter element reaches two years.

According to the professional introduction of Lanze Water Purification in Canada, the filter element replacement cycle of household water purifier is determined according to the quality of the filter element, the quality of the filtered water, and the amount of water filtered.

According to the different local raw water quality and household water consumption, the service life of the filter element and filter media is different.

There are two filter elements at the end of the water purifier, the first section CF+CB composite filter element, the recommended replacement time is about 12 months, and the second section of the RO membrane filter element, the recommended replacement time is 24-36 months.

The ultrafilter has a total of two filter elements, the first section of the CF filter element, the recommended replacement time is about 12 months, and the second section of the UF filter element, the recommended replacement time is 24 months.

**The recommended replacement cycle of the filter material barrel of the water purifier is 24-36 months, and the filter material purification capacity of the water purifier will change with the extension of the use time. When it is time to replace the filter element, because its adsorption of toxic and harmful substances in the water will slowly become saturated, although it can still meet the requirements of water purification in the short term, it will also cause secondary pollution if it is not replaced in time, so in order to better protect the safety and health of your household water, it is recommended to replace the filter material in time.
