Previously issued a tweet "long article to understand a variety of water purifiers, businessmen do not want to fool you", the background received a lot of friends consulting.
Some time ago by a platform editorial appointment, online to do a discussion on the topic of water purification equipment, to answer the more concerned about the issue, is now organized into an article to share out.
01.
Q: My family has a super lazy little brother, can not wait to open the tap to drink water directly, I want to ask to install what kind of water purification equipment to meet?
A: I'm also super lazy, in order to your little brother's health, remember the poor monk a sentence no matter what his equipment is called, just see if there is RO membrane.
In my opinion, only after the RO membrane filtration is the real meaning of the direct drinking machine to remove bacteria and heavy metal ions! As for other ultra-filtration machine, water purifier or multi-stage filtration drinking machine, as long as there is no RO membrane, 180-stage filtration I also recommend that you boil before drinking.
02.
Q: Is the water purifier the more the better? I've heard that only water purifiers with RO reverse osmosis are useful? Thank you
A: This question is relative, the more filter cartridges filter more thoroughly, but with the type of cartridge has more to do with, as said five PP cotton cartridges are not as thorough as a RO membrane filtration. To make an image of the analogy, the cartridge is a fishing net, the impurity is the fish, the fishing net hole is big, how many sets of layers are not able to net the small fish.
"Only with RO reverse osmosis is useful water purifier" this sentence is not rigorous.
Water purification machines including front water purifier, central water purifier, ultrafiltration machine, water softener, RO membrane reverse osmosis drinking machine, etc., each category has its specific efficacy and role, according to the needs of the selection. But my point is that only RO membrane reverse osmosis water purifier is the real meaning of drinking water machine.
03.
Q: Is the water purifier to buy the kind of plug-in good, or a filter of the kind of better ah?
A: The question is not too detailed ah, then I will answer according to my understanding.
You said that the kind of plug-in is generally RO membrane reverse osmosis drinking machine, plug-in is to pressurize the water through the RO membrane.
A filter should refer to a cartridge, now on the market water purifier is rarely useful single cartridge. Maybe you're talking about the kind that integrates several filter materials into a single cartridge consumable, the kind that needs to be replaced as a whole when replacing.
No matter what kind of filter he is, but from the point of view of drinking is certainly more recommended RO membrane drinking machine (but will produce waste water), but if you do not need so high filtration accuracy, with other types of water purifiers is not too much of a problem, boiled and drink it is good.
You didn't specify a brand name and model number, and I don't know what kind of product you're talking about for a cartridge, so I can't give you a direct purchase recommendation. However, I presume that the one-cartridge type is either space-constrained or coarse-filtered, either of which is a compromise expedient, so don't use it if conditions permit.
04.
Q: general household need to install a central water purifier?
A: see this question I was confused, the average family is what family ah? The family has a mine ah
An installation of the central water purifier is to see the requirements of the individual, belonging to the advanced equipment.
Family water purification system, in accordance with the purchase and use of costs, the degree of difficulty of transformation, cost-effective to consider, I recommend: front > RO water purifier > ultra-filtration machine > central water purification. First of all, to ensure the safety of the entrance, and then enhance the use of comfort. Water softener is to enhance the comfort, not a necessity.
The role of the central water purification is: further purification on the basis of pre-filtration. It can be divided into those with and without ultrafiltration membranes.
Without ultrafiltration membrane: can effectively remove chlorine, rust, heavy metals, viruses, algae and solid suspended solids in the water, so that the treated water is clear and clean.
With ultrafiltration membrane: can remove bacteria, but also can achieve the above effect, with the ultrafiltration machine is the difference between the processing capacity is larger.
Installation of centralized water purification, and then install RO water purifier, but also greatly extend the service life of subsequent water purification equipment and water appliances. However, the disadvantage is: the central water purifier is generally larger, which is not friendly to small households. Therefore, it depends on each person's needs and conditions to decide whether to install.
05.
Q: Central water purification is large, small homes too much space, is there a compromise program? I've heard that replacing the front with a blue bottle of some sort or other will result in better filtration? Or other convenience that can be close to the central water purification.
A: You said the big blue bottle may be Pentair's big blue it, this product is equivalent to the front of the cartridge, according to the cartridge of the different purification effect is different.
The package has a whole-house mini type central water purification front, the principle is in fact no difference with the central water purifier, the required installation size is really relatively small, if the space is really limited can be considered. But still, under the same premise of the quality of the filter material, the larger the volume and dosage, the better the effect of filtration.
The following picture is schematic, does not represent the product recommendation:
06.
Q: Da Sheng, please advise, according to your home that design, even if the central water purification seems to take off the impact is not too big, the living water over the water softener, drink away ro pure water, so ask the central water purification is a what role?
A: Central water purification is the icing on the cake, all the water in the main pipeline through the central water purification, in addition to residual chlorine and most of the impurities, bathing reduces the residual chlorine damage to the skin, but also reduces the end of the pure water purifier purification burden, increasing the service life of the cartridge.
Emphasize that soft water is not purified water, just remove the calcium and magnesium ions in the water, other harmful substances did not change.
07.
Q: I want to bath water and other non-entry water quality to do a simple enhancement, whether the installation of pre-filtration is sufficient? Which type is better?
A: Simple enhancement, the simplest is to add a pre-filter, first of all, to filter out the sediment and so on. Next is the central water purifier, which removes residual chlorine and reduces harm to the human body.
And then, is the central water softener, but the price and late use of higher costs (plus salt), however, soft water shower and laundry is another experience, such as limescale is greatly reduced, after washing the body slippery, clothing will not be washed more and more hard. About shower water softening there is a cheap version of the solution, Taobao search "shower water softener" you will have a surprise, the price of a few hundred dollars.
08.
Q: Now the house in the renovation, in the decision has been made will be installed on the basis of front water purification, if it is for the laundry and bathing water is relatively clean (after all, hair loss star bent on reducing the chances of hair loss ...) Is it recommended to install a water softener for laundry and bathing water?
A: Your needs have been very clear, you are the precise user of water softeners ah! The water is too hard, it does exacerbate hair loss, then you can now consider the design of the water circuit
09.
Q: home water purifier need to install a pre-filter?
A: Need! Pre-installed in the entry of the main bar, filtering sediment and other large particles of impurities, to protect the water apparatus, and the price is not expensive, backwashing type also has no late maintenance costs, once and for all, why not.
10.
Q: front + hollow fiber filtration effect?
A: Hollow fiber is a what? General water purifier filter material PP cotton, activated carbon, ultrafiltration membrane, RO membrane, I guess you say that thing should also be a kind of filter material, and the role of activated carbon is almost the same. But this kind of thing filtration accuracy is general, do not drink directly, boil drinking.
Recommended program: front + dual water RO membrane reverse osmosis water purifier
11.
Q: Please ask the front water purifier can still be installed after renovation! Will it affect the water pressure? Recommended brand chant!
A:
①? As the front is connected to the main pipe, so it is best to get it done during the renovation. It's not impossible to add it when the renovation is done, but you have to consider whether there is enough space for the arrangement. If there is enough space, any plumber can handle it. When installing, pay attention to the direction of the water inlet of the machine, do not install the opposite.
②? Before installation also depends on which kind of pre-filtration is more suitable for you. The greater the filtration accuracy, the stronger the attenuation of water pressure. I do not know how much water pressure you now, pre-filtration precision between 40-100 microns, if you are afraid of small water pressure can choose a larger pore size.
③? If it is a backwash front, nothing technical, depending on what price you want to buy. The difference is not big, Hans Hill, 3M, Honeywell, the domestic United States, Qinyuan, Haier can be.
12.
Q: The more you look, the less confident you can find the right water purifier. God to recommend two brand models for home use, right?
A: My goodness, you've raised one of my biggest concerns! How do I know, I'm not Baidu, and no one gives me advertising money? Every brand has good products and pitfalls, where to say.
Tell me about my home: I use my own direct drinking machine Qinyuan. Front then, I do not recommend imported, this thing does not have a lot of technical content, domestic backwash is enough, the money is arbitrary I do not care. Water softener words, Ekou and Pentair.
But we can recommend a few brands, are the old big factory, relatively reliable (that is, some brands have a high premium, a little feel that we are stupid money mean):

Today write and send so much, please pay attention to the second issue. As can be seen from the question, many people are still very unaware of the water purification equipment, it is recommended to click on the link at the beginning of the article, review my previous tweets, after all, the role of different types of water purification equipment is different, we need to be based on their own needs in order to choose the right product for them, do not just let others recommend, remember "my honey your arsenic! "
13.
Q: Is it necessary to install water purification equipment? There are recommended brands
A:
① Necessary! As for the reason why click on my avatar there is an article dedicated to water purification system, said the people, if the budget is limited, the first on the front, and then add a dual water RO membrane reverse osmosis water purifier
② with its brand or look at the consumables more practical, pay attention to the RO membrane which is produced, Dow, GM preferred, Shihan, Toray, followed, and again domestically produced. However, Dow membrane is also divided into Dow membrane domestic processing and original Dow, and then there is the problem of real and fake goods, which does not expand, the water is too deep, pick to hear over the brand to buy a relatively reliable point
