Is it better to plug in a household water purifier or not?

From the perspective of environmental protection, it is definitely better to be unplugged, but in terms of the cleanliness of our drinking water, the filtration accuracy of plug-in water purifiers is much higher. The difference between plug-in and unplugged water purifiers:

A plug-in water purifier is what we often say"Water purifier"That is, RO reverse osmosis water purifier.

Its filtration accuracy is about microns, and it can filter out almost all harmful substances in tap water, such as heavy metals, viruses, fluorescents, pesticide residues, etc.

Reverse osmosis water purifier is what we often call reverse osmosis and RO membrane.

It mainly uses reverse osmosis membranes.

technology, which works by applying a certain pressure to the water to make the water molecules.

and ionic mineral elements through the reverse osmosis membrane, and most of the inorganic salts dissolved in water.

Including heavy metals), organic matter, bacteria, viruses and other impermeable reverse osmosis membranes, so that the permeable pure water and impermeable concentrated water are strictly separated.

What does not need to be plugged in is an ordinary water purifier, which is generally an ultrafiltration machine. Its filtration accuracy is about microns, and it is necessary to filter harmful substances such as bacteria, rust, colloids, sediment, suspended solids, and macromolecular organic matter.

The unplugged ultrafiltration water purifier mainly passes through the filter membrane, and when the water passes through this tubular structure with fine pores, the fine porous impurities are filtered out. There are different materials to choose from (PVDF, Pan, PVC), and they are also divided into internal and external pressure.

Plug-in uses a reverse osmosis water purifier, and does not need to be plugged in is an ultrafiltration water purifier.

The pure water filtered out by the reverse osmosis water purifier can be drunk directly, and there is no scale after boiling the water. However, it will produce a large amount of wastewater, which is suitable for users with poor water quality.

Ultrafiltration water purifiers not only do not need power supply, but also do not produce wastewater, but the filtered water is called purified water, which needs to be boiled before drinking, and it will also produce scale. It is suitable for washing vegetables and cooking, and the ultrafiltration water purifier is suitable for users with average or poor water quality.

Nowadays, it is also common to introduce hybrid water purifiers with both pure water outlets and water purification outlets.

No matter what kind of water purifier, the filter element inside must be replaced regularly according to the quality of the local tap water and the amount of water used, such as the PP cotton filter element, the service life is between 3-6 months, the activated carbon filter element is between 6-12 months, and the reverse osmosis filter element or ultrafiltration filter element is about 24 months.

If the filter element is not replaced within the time limit, the water purifier will become a dirt collector, which will cause damage to human health.

It stands to reason that from the perspective of environmental protection, it is definitely better if it is not plugged in, but in terms of the cleanliness of our drinking water, the filtration accuracy of plug-in water purifiers is much higher, so there are pros and cons to each.

Plug in well.

The electric water purifier has high filtration accuracy, which can remove harmful substances in the water, and also has a sterilization and disinfection effect. The water pressure of the water purifier without electricity is small and the water will be very slow, so you should pay attention to the water pressure at home when choosing.

The working principle is to exert a certain pressure on the water, so that the water molecules and ionic mineral elements pass through the reverse osmosis membrane, and most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses and other inorganic salts dissolved in the water cannot penetrate the reverse osmosis membrane, so that the permeated pure water and the impermeable concentrated water are strictly separated.

Precautions for the use of water purifiers.

Be sure to rinse before use. Be sure to rinse the water purifier for a few minutes before use, some household water purifiers may have been placed for a long time, and impurities and bacteria may seep into it, just rinse for a few minutes, the same reason, if the water purifier at home is not used for a while, it will also need to be rinsed for a few minutes next time when you use it.

Replace the filter cartridge regularly. The filter element of the household water purifier is to be replaced regularly, the general water purifier contains PP cotton filter element, activated carbon filter element, ultrafiltration membrane or RO membrane filter element, etc., the replacement time of each filter element is different, PP cotton is changed once from March to June, activated carbon is changed once from June to September, and ultrafiltration membrane or RO membrane is changed once every two to three years.

The above content refers to People's Daily Online-Household Water Purifier is not very useful.

To put it simply, plug-in is a RO machine, and unplugged is mainly an ultrafiltration machine, the former removes scale, and the latter does not remove, and that's it.

Plug-in reverse osmosis is much better than unplugged ultrafiltration. There is also unplugged reverse osmosis. Reverse osmosis is bought online for about 400 to 1000 yuan.

Ultrafiltration is about 200 to 500 yuan. I have bought more than 400 reverse osmosis and used it for more than a year, to be honest, it is very easy to use, but the original electrical appliances are broken. In addition, there is a concern that electricity that is too cheap is not safe.

I spent 330 yuan on the Internet to buy a Yiguan wo75 unplugged reverse osmosis, reverse osmosis may be the one that does not need to be plugged in, and there are certain requirements for tap water pressure. It is not easy to break if it is not plugged in, and there is no need to worry about the safety of electricity. In use, the TDS value of 400 drops to 20.

The ultrafiltration machine does not need to be plugged in, and the reverse osmosis machine needs to be plugged in. Generally, if the water quality is good under normal conditions, it is recommended to use an ultrafiltration machine. It can filter out tap water chlorine, impurities, etc., and the final water can reach the standard of raw drinking, retaining the trace elements useful to the human body in tap water; Regarding the reverse osmosis water purifier, it can take all the substances in the tap water into account, and the water that comes out is pure water, which is definitely better than the water that can be drunk raw from the ultrafiltration machine, although the water from the water purifier has minerals, but it is very few.

If you use an ordinary water purifier, the purified water can not meet our normal drinking water standards, and the internal filter element of the water purifier is very damaging.

The water purifier is plugged in because there is an electric water pump, which can pressurize the water, so that the water can pass through the filter membrane more easily. It is characterized by stable water pressure, large and fast water production, and relatively less wastewater. The water purifier is not plugged in, it relies on the pressure of the tap water to filter the water through the filter membrane, and the pressure of the tap water is unstable, which will affect the water production.

Therefore, it is relatively poor in terms of water production, water production speed, wastewater rate, etc. Of course, if the tap water pressure in the individual's location is stable, the above is not a problem. To sum up, I personally feel that it is relatively better to plug in.

Hope it helps.

Have a great day

The plug-in is a reverse osmosis water purifier, and the water is pure water, which can be drunk directly, but pure water does not have any other substances, including harmful substances and beneficial substances, and long-term drinking in large quantities is not good for human health. Moreover, the wastewater rate of reverse osmosis water purifier is very high, especially in winter, the wastewater rate can reach up to 7 percent, and the water purifier cannot be used after a power outage.

The water purifier that does not use electricity is usually an ultra-filter element, which cannot be drunk directly after purification, and must be boiled before it can be used, which is suitable for washing vegetables and cooking water.

First of all, you have to understand in detail the functional characteristics of various brands and models of water purifiers, any water purifier has its advantages and defects, understand your local tap water quality, and then buy according to your own eating habits, the best one for yourself.

At present, there are many varieties of water purifiers of various brands and models, including those with multiple filter elements, single-core ultrafiltration, those that can produce water without electricity, and those that must be powered on to be used, as well as those with multiple water outlets, pure water outlets, and water purification outlets. Pure water can be drunk directly, but it has no nutritional value, just rehydration. Purified water needs to be boiled before drinking, especially suitable for cooking and washing food in the kitchen.

In addition, the need for electricity to use generally will produce wastewater, especially in winter, the wastewater rate is as high as about 70%, reverse osmosis water purifier is to filter out the harmful substances and beneficial substances in the water.

The service life of multiple filter elements is also very different, such as PP cotton filter element, the life span is only 3-6 months, activated carbon filter element, the life span is generally between 6-12 months, and the life of ultrafiltration or reverse osmosis filter element is generally about 24 months. If it is too troublesome to replace the filter element on schedule, then buy a water purifier with a long life and do not need to replace the filter element frequently, and if the local water quality is better, there is no need to buy a water purifier. If the local water quality is too poor and the drinking water quality is a problem, you can consider buying a reverse osmosis water purifier, also known as a water purifier.

The on-site manufacturer has also launched a water purifier with multiple water outlets, with a pure water outlet, which can be directly drunk, and a water purification outlet, which is suitable for boiling water for cooking.

In addition, it is best to purchase a pre-filter at the same time when installing a water purifier to extend the service life of the water purifier filter element.

The plug-in is the RO reverse osmosis machine, and the unplugged is the ultrafiltration machine, that is, the ordinary filtration, without the fineness of the RO filter. If the water quality is poor, it is recommended to use a RO machine, the purification effect is very good, very thorough, its filtration precision is very high, only water molecules are allowed to pass through. If the water quality is better, ultrafiltration is enough for pure physical filtration, no electricity is required, only the pressure of tap water is enough.

It is better to plug in, but the water purification function of the water purifier does not use electricity at all, relying on the pressure of water to make the water pass through the permeable membrane, activated carbon, PP cotton, etc., so there is no difference in the water purification effect.

What needs electricity is some additional functions such as heating, refrigeration, control, and display, which will be better if they have them, and they will not affect water purification!

The difference between plugged in and unplugged water purifiers is as follows:

1. The working principle is different.

Unplugged water purifiers usually use water pressure to pass tap water through the relevant filter element to achieve the purpose of purifying water quality. The most common filter elements are activated carbon and ultrafiltration filters, which can filter out suspended solids such as rust and sediment, residual chlorine, odor, discoloration, some organic matter, colloids, and bacteria from the water.

The working principle of this reverse osmosis membrane technology is to apply pressure to the tap water, so that water molecules and ionic mineral elements can pass through the reverse osmosis membrane, while the inorganic salts, organic matter, bacteria, viruses and other dissolved in the water will not be able to penetrate the reverse osmosis membrane.

2. The power consumption is different.

The most important thing about unplugged water purifiers is that such water purifiers only need to pay the cost of replacing the filter element in the later stage. There are no other additional fees. The cost of plug-in water purifier will be relatively high, in addition to the electricity bill, the RO reverse osmosis water purifier will also produce wastewater, which is actually specially used to collect and discharge impurities, rinse and clean up the impurities around the RO membrane at any time, so as to prolong the service life of the RO membrane.

Precautions for choosing a water purifier

It is necessary to start from the consumer's own situation. If the water quality of the residence is good, and there is no reserved power socket in the kitchen, and you are not willing to re-groove and route, you can choose not to plug in the water purifier. If the water quality of the residence is poor, and you have high requirements for water quality, and you want to drink directly in a healthy way, it is recommended to plug in the water purifier.

The wastewater discharged from the plug-in water purifier can also be reused, and if there are plants at home, it can be used to water flowers; It can even be used in the toilet as water to flush the toilet; When doing hygiene, you can also make good use of this waste water to mop the floor, wipe the table, etc.

Unplugged filtration is less accurate.

I want to ultrafilter. Some do not meet the hygiene standards.

Now the good ones are all to be plugged in.

RO reverse osmosis water purifier.

A water pump is required to pressurize the purified water.

From the perspective of environmental protection, it is better if the water purifier is not plugged in, but from the cleanliness of the user's own drinking water, the filtration accuracy of the plug-in water purifier will be higher than that of the unplugged one.

The plug-in filtration is relatively clean, and the main thing that is not plugged in is to filter some bacteria, rust, colloidal sediment and other harmful substances of macromolecular particles, but there is no way to filter out the harmful substances of small molecule particles with ultrafiltration water purifiers, because the technology of stupid acacia needs to be filtered with electronics, and there is no way to completely filter out the fine harmful substances with physical filtration, so the filtered water is still harmful to the human body.

Water purifier purchase skills.

1. Select according to local water quality.

The principle of the water purifier is to filter harmful substances to the human body and purify the water quality through the terminal water treatment method. Depending on the water quality in different places, the functional design of the water purifier is also different. Generally speaking, the water quality in the north is hard and there are many impurities, so you should choose a water purifier or water softener with ion exchange resin filter element.

The water quality in the south is soft, heavy metals and secondary pollution are serious, and families with high water quality requirements can choose a pure water machine, and if the local water quality is better, you can choose an ultrafiltration machine.

Second, the filter element must be suitable.

Water purifiers are mainly made through activated carbon.

Simple filtration of ceramics is easy to breed bacteria and pollute water sources; The second-generation water purifier uses artificial polymer membrane filtration, which has a significant effect on removing harmful substances in the water, but it also filters out trace elements that are beneficial to the body.

The third-generation water purifier adopts nanocrystalline filter technology, which solves the defects of the second-generation water purifier. Therefore, when choosing a water purifier, you must be clear about the filtration technology and filter material.

3. Understand the filtration level of the water purifier clearly.

Many consumers will think that the water purifier is the more stages the better, and they are willing to spend a lot of money to go to the 8th to 10th level filtration products, many high-level filtration products on the market are filtered through repeated filtration, and the filtration effect is the same, in fact, we need to remove the role of each section of the filter element when we consumers of water purifiers. Water purification products are developed according to different use needs, and the filtration levels of the products are different to meet the needs of consumers in all directions.
