In the Wukong Q&A, I often see people asking, how to choose a water purifier? On this issue everyone's needs are different, the choice is also different, for this I problem I set up a few questions, if you can figure out this several questions, then you know how to choose.
1.0 Which ultrafiltration water purifier or reverse osmosis water purifier to choose?
2.0 Which is the bucket water purifier or the bucketless water purifier? (For reverse osmosis water purifiers)
3.0 Which three-legged filter bottle water purifier or box water purifier to choose?
4.0 Which brand water purifier or miscellaneous water purifier to choose?
5.0 Which is the choice between the kitchen water purifier and the kitchen water purifier?
6.0 Which is the modular filter element or the ordinary filter element?
7.0 Do you choose domestic or imported core components (ultrafiltration membrane or ro membrane)?
8.0 Which is the choice between single outlet water purifier and double outlet water purifier?
9.0 Assemble your own water purifier or buy a finished water feeder?
Recommendation: Choose as needed
reason:
Scenario 1: The domestic water is mountain spring water, there is no scale after the water is boiled, there is no heavy industry nearby, the water resources are not polluted, this water quality has no calcium and magnesium ions, no heavy metals, and the main impurities are sediment and rust in the water pipe. In this case or similar situation, it is recommended to install an ultrafiltration water purifier, mainly to filter the solid impurities in the water.
Scenario 2: Tap water when domestic water is used, there is heavy industry around the city where you live, water pollution incidents have been reported nearby, or you live in a high-rise building, or the scale in boiling water is more serious. It is recommended to install a reverse osmosis water purifier, after filtering is basically pure water, boiling without scale, can drink water is the top priority, do not care about the minerals in the water.
Recommendation: Choose a bucket-free design
Reason: At present, the mainstream reverse osmosis water purifier chooses a small membrane bucket design, which has a barrel design in the barrel is a pressure barrel, for the pure water machine below 100g, the pressure barrel plays an irreplaceable important role, the use of pressure barrel is to solve the contradiction between the small membrane water purifier and the use of water, when the user does not take water, the pure water machine is working, the pure water produced is first stored in the pressure barrel, when the user needs water, directly from the pressure barrel to the outside output, the user does not have to spend time waiting for the water.
From the above description, we can know that there is a bucket design of the water purifier, pure water is stored in the pressure barrel in advance, if the water is not used for a long time, the water in the pressure bucket may have to be put for a few days, there is a possibility of secondary pollution, the use of no bucket water purifier, ready-made, to ensure that the water quality is fresh, but also to avoid the pressure barrel secondary pollution.
Recommendation: If the space is large enough, choose a three-legged filter bottle water purifier
Reason: Compared with the box water purifier, the three-legged filter bottle water purifier has the following advantages: 1) the filter element is relatively cheap; 2) the use of full-size design, the filter element is sufficient; 3) the structure is simple, and the maintenance and inspection are convenient. 4) The price is relatively low. The box water purifier is characterized by high integration and small space.
Suggestion: If you want to buy a brand with peace of mind, the top 10 list can be; in pursuit of cost performance, you can choose a qualified water purifier with a miscellaneous brand and a water batch.
Reason: In fact, the current reverse osmosis water purifier technology has been very mature, the quality of domestic RO film has been very high, and the difference with imported ro film is that the salt removal rate is 98% domestic, imported 99%, this difference is almost insignificant, domestic brands and miscellaneous brands are nothing more than such a little difference. As for the effect, even the brand can not do no problem at all, it is recommended to buy a tds detection pen, often do testing, do it in mind.
If you have strong hands-on ability, like diy, have a certain theoretical basis, you can also buy accessories online to assemble a water purifier yourself, make one yourself, the price is within 450 yuan.
Recommendation: Conditions allow to choose a kitchen water purifier.
Reasons: 1) At present, the sink has two installation holes for installing faucets, and the space under the stage is sufficient; 2) the wastewater discharge is convenient and directly discharged to the sewer pipe; 3) there is no clear line, no clear pipe, and the surrounding area of the sink is clean and tidy.
Recommendation: Prefer a normal filter element
Reason: The filter element belongs to the consumables, such as the first level of pp cotton filter, basically 3-5 months to replace, ordinary pp cotton first stage filter element is only a few yuan, and the quick plug modular filter element needs dozens of yuan. In addition, the ordinary filter element is not so difficult to change, and the last way to avoid secondary pollution caused by the filter element is to change the filter element frequently.
ps: Replace the filter should be precautions 1.Check the length of the filter: Compare the length of the new and old filters, if the length of the new filter is insufficient, you can solve the problem by increasing the rubber pad. (Rubber pads can be removed from the old filter) 2. When placing the filter, we should pay attention to the correct filter, especially pp is easy to deflect, when twisting the filter bottle, you should feel it by the feel, do not twist hard when you can't screw it, and unscrew the filter bottle to put the filter center back on the right, so as not to damage the filter. The granular activated carbon has a rubber pad on the other end facing upwards, and the small t33 is marked with the direction of the water flow. 3. After the installation of the filter core to be rinsed in order to be connected to the system of the rear level, the pipeline of the next level is disconnected when flushing, the ro level can be flushed with electricity, the ultrafiltration water purifier only needs to open the water intake ball valve to flush, the flushing time is at least 5 minutes, and the lower level treatment system is connected after the flushing is completed. 4. The use time of the filter depends on the water quality, generally 6-8 months, pp can be washed and used, it is best not to exceed 1 year.
Recommendation: Domestic membrane
Reason: At present, the ro membrane technology has been very mature, the domestic Huitong membrane manufacturers from the United States to introduce reverse osmosis membrane full process production line and process technology, through digestion, absorption and innovation, research and development and manufacturing of industrial general membrane elements, seawater desalination membrane elements anti-pollution membrane elements, antioxidant membrane elements and household membrane elements, etc., is the world's second manufacturer with large-scale production capacity of dry membrane elements. The desalination rate of Huitong membrane is 98%, and the service life is 2-3 years. The desalination rate of imported membranes can reach 99%, which is insignificant for daily life and supports domestic products.
Recommendation: Double outlet water purifier
Single water: single-way pure water, that is, water that passes through pp cotton + granular activated carbon + compressed activated carbon + ro membrane + rear filter element, five-stage filter out of scale heavy metal bacteria, etc., will drop tds, will discharge wastewater, can be directly drunk.
Double effluent: two ways out of the water, one way is through pp cotton + granular activated carbon + compressed activated carbon out of the water, that is, water purification, 3 grades of coarse filtering out sediment, impurities, adsorption of residual chlorine, but not through the ro film, so do not produce wastewater, do not drop tds, do not filter heavy metals and scale, can not drink directly, suitable for washing dishes, washing dishes and brushing teeth, etc.;
Double water outlet and single water comparison, more than one way water purification, suitable for users who want to use purified water / pure water alternately healthier, double water purifier needs to be equipped with double outlet faucet.
