There will be debates about DIY water purifiers and brand machines on many platforms, and the two sides are divided into two factions, one is the brand machine party, and the other is the manual party.
The brand machine party is nothing more than that it is troublesome to purchase and assemble DIY water purifiers, and there is a risk of water leakage. And the handicraft party thinks that the brand machine is an IQ tax, and I spend a little time assembling it myself, and it is only a few hundred yuan, and the core replacement is also cheap. From the perspective of each other, it actually makes sense.
Next, I will analyze the pros and cons of these two types of water purifiers with you in detail, so that you can choose the most suitable water purifier for yourself.
I see that many people don't look down on the assembly machine, and would rather choose a high-priced brand machine, the main reason is that the quality of the assembly machine cannot be guaranteed. The brand machine does have its advantages, but it is not on the accessories, some of the accessories problems that broke out before, such as the faucet or the rear activated carbon heavy metal exceedance, but they are all brands.
This only shows that there is a problem with the brand opportunity, not that there is no problem with the assembly machine, but that the big brand is not necessarily insured.
You can ask customer service online or the clerk of the physical store, they may not be able to tell the source of each accessory, many brand accessories are labeled customized models, or purchase them back and assemble them yourself, these accessories are not produced by the brand itself.
The real water purifier technology is the manufacturer of reverse osmosis membrane, the manufacturer of water pumps, and the manufacturer of those accessories. The manufacturer of the water purifier has no technology except for the design of a casing, and the manufacturer's propaganda of how powerful it is is is actually a gimmick.
The DIY water purifier can be controlled throughout the procurement process, such as pumps, membranes, faucets, and other accessories can be bought from the brand, and there is no quality risk.
Assembling the water purifier yourself can also save a lot of money, especially the cost of core replacement. But in addition to the trouble, the assembly machine also has the risk of water leakage, and the god with strong hands-on ability is indeed no problem, but ordinary people are indeed a little difficult to face the assembly machine.
Like I suffered a loss when I was DIY before, it took more than a month just to buy parts, either lack of east or west, I wanted to experience the fun of hands-on, but it turned out to be a burden.
Let's talk about the advantages of brand machines, many people choose brand machines mainly for the following reasons:
The first is that the integrated waterway reduces the number of joints and reduces the risk of water leakage. The corresponding price is also rising, and at the same time, it is not a universal filter element, and it will be tied to the ship in the later stage. The original brand filter cartridge is not necessarily stronger than the NSF certified general-purpose filter cartridge bought, and it is many times more expensive.
The second is that the after-sales service will be better. But after-sales is also raised with money, there may be a door-to-door fee, you can't choose what to change, and the whole machine will be scrapped if you don't change it.
The third is aesthetics, there are a lot of bottles and cans of the assembly machine, which is not very beautiful, and then a pressure barrel will occupy a large part of the kitchen space, which is very unfriendly to small families. The brand machine has a slim body, the filter elements are built-in, there is no pressure barrel, and the appearance is beautiful and does not take up space under the kitchen.
In this way, both kinds of water purifiers have their own advantages and disadvantages, so there is no one water purifier that can absorb the shortcomings of both parties and abandon each other's shortcomings.
Don't say it, there really is, it's a universal filter water purifier, let me talk about it in detail.
1. The cost of core replacement is low and cost-effective
The main focus of the general filter element is that the machine and the filter element are not bundled, the filter element can be chosen independently, and the brand RO filter element can easily cost thousands of yuan, and if you buy it yourself, you can buy a pretty good brand membrane for two hundred yuan.
And the price of the water purifier with the universal filter element is generally not high, and it can be done for more than 1,000 yuan, and the cost performance is real.
2. Save time and effort
DIY water purifiers are indeed more time-consuming and laborious, because you first have to determine the parts you want to buy, and then purchase them one by one, and wait until all the parts have arrived, and then install them one by one, which will take a long time.
And before you start, you have to consider a lot of details, such as whether to add a pressure bucket, how to add a pressure bucket waterway, which standard accessories are more appropriate, how much power the booster pump needs to be equipped, how to adjust the wastewater ratio, and how many water pipes are needed for the connection of the filter bottle.
The universal filter water purifier does not need to be assembled by yourself, and you can use it directly when the master comes to install it.
3. Small size and beautiful appearance
The water purifier with a universal filter element is small in size, no different from the normal water purifier on the market, and those bottles and cans without DIY water purifiers have a more beautiful appearance, no pressure barrel, and do not take up space when placed under the kitchen.
4. There is after-sales
Like what I said earlier, some people may disagree, thinking that my hands-on ability is strong, my time is not valuable, and cheap is king.
But you also ignore the most important point, that is, the water insurance of the water purifier, the machines of professional manufacturers, there are water leaks from time to time, you will be able to ensure that the machine you install has no risk of water leakage?
If you buy a water purifier with a universal filter element, at least there is after-sales insurance for you. So I suggest not to lose the watermelon for the sake of sesame seeds, not afraid of 10,000 just in case, the leakage is really not guaranteed.
The consideration I recommend the universal filter water purifier is that professional things are left to professional people, and the risk of water leakage is handed over to the business, as for the filter membrane of cutting leeks, replace it yourself, I think this is the most economical and affordable way at present.
The water purifier of the universal filter element is not a one-eyed one, you can buy it casually, and you should also look at all kinds of parameters before buying, just like the membrane, pump, wading accessories, etc. we mentioned before, and there are some experience parameters that affect the water purifier, such as flow rate, waste water ratio, etc.
1. Pumps
The pump and membrane must be the best, especially the pump, which determines the life of the water purifier that can run.
The best pump on the market is Delta, Delta pump adopts independent patented structure, low energy consumption, high efficiency, long service life, and relatively small noise during use, so try to choose the brand Delta when choosing a pump.
2. Membrane
The membrane is also a very important part of the water purifier, the membrane determines the cleanliness of the water purifier filtration, and a good membrane has strong durability and high stability.
In addition to Dow membrane, Toray, Huitong, and Shihan are also more famous, and the water purification effect of the filter element is also good.
In fact, the current reverse osmosis membrane domestic Huitong (that is, Wharton), the quality has been with the awesome, household water purifiers generally do not need to care too much about whether it is a domestic or imported reverse osmosis membrane, as long as the inlet water quality is not very poor, Huitong membrane is sometimes better than Dow, if the salt content of the inlet water source is too high, it is true that Dow's membrane treatment capacity is better, but it is a high-pressure membrane, not in the scope of discussion.
Moreover, the Dow film used in the current water purifier is rolled by the merchants themselves, which is not a real Dow film, so it is absolutely enough to buy domestic Huitong, and the price is cheap.
3. Throughput
The flow rate of the water purifier is the water flow rate of the water purifier, generally there are 600G, 800G, 1000G these parameters, G is the gallon, 1 gallon is 3.78 liters.
600G is the water production of the water purifier for 24 hours: 600×3.78 = 2268L, that is, the 600G water purifier can produce 2268L of water a day, so the larger the value, the greater the flow rate of the water purifier.
In the general concept, the higher the flow rate of the water purifier, the better, because the higher the flow rate, the shorter the waiting time for water connection.
But in fact, the larger the flux, the greater the consumption of the diaphragm, resulting in an increase in the cost of our core replacement, usually the water output in the range of 800G-1000G is more reasonable, neither because the water output speed is too large and excessive consumption of the diaphragm, but also because the water output speed is too small to affect the water experience, considering the cost, the choice of 800G this flux is enough.
4. Wastewater ratio
Let's first talk about why the water purifier discharges wastewater, the molecular impurities in the water will lead to the saturation of the aqueous solution in the process of long-term accumulation, and after the water is saturated, the soluble salts in it will precipitate crystals.
Because the pore size of the reverse osmosis membrane is very small, only 0.0001 microns, these crystal impurities will cover these tiny pore sizes, thereby damaging the reverse osmosis membrane and leading to the early scrapping of the diaphragm.
If the reverse osmosis water purifier does not discharge wastewater, the service life will be greatly shortened, so it is concluded that the wastewater ratio of reverse osmosis is directly related to the life of the diaphragm.
When the more wastewater is discharged, the lower the operating pressure of reverse osmosis, the better the quality of the produced water, and the longer the life of the reverse osmosis water purifier. On the contrary, the less wastewater, the higher the pressure of the reverse osmosis machine, the worse the quality of the produced water, and the shorter the life of the reverse osmosis membrane. It's like an opposite, you can only choose one side, you can't have both.
Overall, a wastewater ratio of 2:1 is reasonable, and this parameter is not too wasteful of water.
5. Safety
The safety of the water purifier, we mainly look at whether the accessories contain harmful chemicals, such as scale inhibitors, bisphenol A, etc., whether the faucet is made of stainless steel, and the wading accessories must be safe, because this is related to the health and safety of our drinking water.
Here is the focus on the problem of scale inhibitors that many people are concerned about, many people talk about the discoloration of scale inhibitors, and think that scale inhibitors are harmful and not beneficial, so why do businesses add scale inhibitors?
Because it can reduce the blockage probability of the RO membrane filter element and prolong the use time of the water purifier, the dosage of the antiscalant is strictly controlled in the process of adding antiscalants. The harmful ingredient in the "scale inhibitor" is mainly "phosphorus", and after several times of dilution, the harm itself is already minimal.
The key is that under normal circumstances, the antiscalant cannot pass through the RO membrane at all, that is, it will flush into the sewer with the wastewater, and the possibility of entering the pure water end is very low, of course, the possibility of RO membrane failure cannot be ruled out. Even if it is squeezed by osmotic pressure even a little bit in a shutdown state, its content is far less than a bottle of Coca-Cola, like a grain of salt in a glass of water.
Therefore, compared to the dosage of antiscalants, there is no need to worry too much, after all, most water purifiers on the market contain antiscalants, and they cannot be produced and sold if they are not qualified.
If you really don't feel at ease, then you choose a water purifier that does not contain antiscalants, after all, it is a peace of mind
6. Water leakage insurance
The last is the water leakage insurance, the water leakage insurance can be understood to help you to cover the bottom, of course, it is best not to leak, once the water leaks and floods the house, it is inevitable to put tens of thousands of dollars into it. Therefore, before buying a water purifier, you must see if the merchant has water leakage insurance, but even if there is no water leakage insurance, the brand after-sales service of the water purifier will definitely help you deal with related problems.
There are really few manufacturers of universal filter cartridge water purifiers, you can go to a certain treasure and a cat to search, there are really few, and the ones sold are not expensive, because they really don't make money, at least they don't make money from your filter cartridge, so the range of options is relatively narrow.
Among these only few brands, I was pleasantly surprised to find a reverse osmosis water purifier that is more brilliant in all aspects, and the points I said above can be covered, so I immediately placed an order, and has been using it for a while, which is this net small energy reverse osmosis water purifier.
At first glance, it feels delicate and small, and it looks more delicate in the assembled water purifiers on the Internet, without pressure barrels, and does not occupy space under the kitchen, which is similar to ordinary water purifiers on the market.
The pump uses the best delta on the market, the membrane uses the Dachang Huitong membrane, the material is not picky, the water output of 800G is suitable for most families, and the net waste ratio of 2:1 is just right.
There is a water quality TDS display on the surface of the water purifier, which can monitor the water quality in real time, which is relatively intelligent. The five-chamber water pump significantly improves the noise level and makes almost no sound when installed in the kitchen.
There are four-stage filter elements in the water purifier, which are free for business, which are PP cotton filter element, activated carbon filter element, RO membrane filter element and post-activated carbon filter element.
PP cotton is mainly used to filter macromolecular impurities, activated carbon is used to adsorb different colors and odors, in addition to the RO membrane, there is a post-activated carbon to improve the taste of water quality, so that the water is more sweet, of course, some people think that chicken ribs, can be installed or not, and does not affect filtration, because this carbon rod is installed behind the RO membrane.
Another highlight of the net small energy water purifier is the flexible water function.
You must know that the machine with zero stale water has to flush the machine every ten minutes, which costs water and electricity, and the water purifier of Jingxiaoneng solves this problem very well, the machine will automatically flush for 30 seconds after each power-on, and every six hours after the power-on, the machine will automatically flush once, it also has a flushing button, when you want to flush the filter element, press the button on it. Compared with the zero stale mode, this flexible stale mode is more water and electricity saving, and it is quite environmentally friendly as a flushing method.
In terms of safety, the net small energy is also strong enough, the stainless steel faucet, the whole waterway does not contain scale inhibitors, bisphenol A, and the wading parts are made of food-grade materials, and mothers and babies can also use them with confidence.
On the whole, Jingxiaoneng is a water purifier brand that really understands water purifiers and will be considered by consumers, which belongs to the ceiling type of water purifiers.
The price of more than 1,000, with four filter cartridges, the cost performance is really high, I have been buying and using it for a while, the feeling in all aspects is still good, you can buy according to your own needs.
