A: I'm also super lazy, in order to your little brother's health, remember the poor monks a sentence regardless of what his equipment is called, it depends on whether there is a RO membrane.
In my opinion, only after the RO membrane filtration is the real meaning of the direct drinking machine, in order 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 filtration I also recommend that you boil before drinking.
02. Q: Is the water purifier the more the better? I heard that only with RO reverse osmosis is a useful water purifier? Thank you
A: This question is relative, the more filter cartridges more thorough, but with the type of filter cartridge has more to do, 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, impurities are fish, fishing net holes, how many sets of layers are not able to net small fish.
"Only with RO reverse osmosis is a useful water purifier" this sentence is not rigorous.
The water purification machine includes front water purifier, central water purifier, ultrafiltration machine, water softener, RO membrane reverse osmosis drinking machine and so on, 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.
The kind of plug-in you said 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 are talking about the kind of several filter media integrated into a cartridge supplies, replacement of the need to replace the whole kind.
No matter how many filter media he is, but from the perspective 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 a big problem, boil and drink on it.
You didn't specify the brand model, 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 this kind of made into a cartridge is either limited by space or coarse filtration, either is a compromise expedient, if the conditions allow or don't use this kind of.
04. Q: general family need to install a central water purifier?
The installation of a centralized water purifier depends on the requirements of the individual, belonging to the advanced equipment.
Family water purification system, in accordance with the procurement and use of costs, the degree of difficulty of transformation, cost-effective to consider, I recommend: front > RO water purifier > ultrafiltration machine > central water purification. First of all, to ensure the safety of the entrance, and then to enhance the comfort of use. 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 larger processing capacity.
After the installation of the central water purification, and then installed RO water purifier, but also greatly extend the service life of the subsequent water purification equipment and water appliances. But 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 heard that the front replaced by a blue bottle or something, the filtration effect will be better? 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 different cartridges produced by the purification effect is different.
The package has a whole-house mini type central water purification front, in fact, the principle and the central water purifier is no difference, the required installation size is indeed 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 filtration effect.
The following chart for the 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 big, living water over soft water, drinking away from the ro pure water, so I 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, and reduces the purification burden of the end of the water purifier to increase the service life of the cartridge.
Emphasize that soft water is not water purification, 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 enough? Which type is better?
A: Simple to enhance the words, the simplest is to add the front water purifier, first of all, the sediment what filtered out. Next is the central water purifier, which can remove residual chlorine and reduce the harm to the human body.
Then, it 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 wash 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 to install the front water purification based on, if it is for the laundry and bathing water is cleaner (after all, the hair loss of the star in order to reduce the chances of hair loss ...) The water softener is recommended 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 pre-filter?
A: Need! Pre-installed in the home on the main bar, filter sand and other large particles of impurities, protect the water apparatus, and the price is not expensive, backwashing type of no late maintenance costs, once and for all, why not.
10. Q: front + hollow fiber filter 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 filter material, and activated carbon role is similar. 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 the 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 in the renovation. The completion of the renovation is not impossible to add, but we 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 installing also look at which 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, domestic beauty, Qinyuan, Haier can be.
12. Q: The more you look, the less confident you can find the right water purifier. God to recommend two brands and models for home use?
My family's situation: I use my own direct drinking machine Qinyuan. Front then, I do not recommend imported, this thing is not too much technical content, domestic backwash is enough to use, money more capricious I do not care. Water softener, Ekou and Pentair.
However, we can recommend a few brands, are the old big factory, relatively reliable (that is, some brands have a high premium, a little bit think we are stupid money mean):

? Haier
In 2010, it set up a joint venture with Israel Strauss to enter the water purifier industry.
Today, write and send so much, please pay attention to the second issue. As can be seen from the question, many people still do not understand the water purification equipment, 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 themselves, do not just let others recommend, remember that "my honey your arsenic" ah
13. Is it necessary? There are recommended brands
A: ① necessary! As for the reasons click on my avatar there is an article dedicated to water purification system of the people said, if the budget is limited, the first on the front, and then add a dual water RO membrane reverse osmosis water purifier.
② Instead of looking at the brand or look at the consumables more practical, pay attention to the RO membrane which is produced, Dow, GM preferred, World Korea, Toray followed by domestic again. 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, this is not, the water is too deep, pick to hear over the brand to buy a relatively reliable point.
