As for the water purifier. I'll share with you the article I wrote on how to buy a water purifier, I hope it can help you.
"Teach you how to buy a home water purification machine" There are a lot of online friends and close friends often ask me a question, how to buy a home water purification machine? This is no longer a case-by-case problem, it is a problem that many people are confused. In fact, how to choose a home water purification machine, the first thing to figure out, what is your own needs? What is the difference between a water purifier and a water filter? After understanding these two issues, your choice will be much easier, not the more expensive the better. First: the difference between water purifier and water purifier 1, water purifier: is through the front 3-stage filtration, and then through the RO membrane reverse osmosis technology principle, to remove most of the impurities and bacteria in the water, and then after the rear activated carbon filtration and improve the taste of water. Advantages: suitable for drinking raw water, you can drink directly, is ready-made water, safe, good taste, no impurities and bacteria in the water. Disadvantages: this machine needs to have the power of electricity, and produce waste water, waste water is generally discharged directly into the sewer, waste water and pure water ratio of 1:1.5-2.5, that is, per liter of pure water need to discharge waste water 1.5-2.5 liters of waste water, of course, there is also waste water reuse, I have done with the 2, water purifier: is the water purified by activated carbon (some machines also have activated carbon). After activated carbon (some machines also use ultrafiltration membrane, or quartz sand class), after KDF filtration directly out of the water machine, some of these machines need regular backwash. Advantages: suitable for kitchen or whole house water filtration, general machines do not need electric, low wastewater generation rate. Disadvantages: the effect of this machine filtration is not as good as a water purifier, the tiny impurities in the water level of bacteria removal rate is not high, do not recommend drinking directly raw water, it is best to boil and drink, this machine will also have a certain amount of wastewater. Second, your needs? 1, you want to drink directly or even raw water or is it filtered? Direct drinking: do not have to consider buying a water purifier directly, even if there is waste water discharge is cheaper than buying bottled water. If it is filtered, the whole house to buy a centralized water purifier, just the kitchen, then buy the kitchen under the type of water purifier. 2, if you both want to drink directly and to the whole house or kitchen filter, then buy a whole house or kitchen under the water purifier, and then buy a water purifier, so that the effect is better, that is, the money to spend a little more. In there is to choose what brand? In fact, only you have heard of the brand can be, even if you have not heard of it does not matter (because the technology of the water machine has been very mature, the current domestic large home appliance companies have not fully into this field, even if some of them into the authorization of other factories OEM production), the key is to look at the sales and after-sales service in your local there is no, this is the key, because of which the company does not dare to 100% guarantee that his Accessories will not be bad, so there are vendors is the most important. Price, depending on the person, each company, each brand price difference, the machine up and down the difference is very big, only buy good not to buy expensive, not the more expensive the better, because the principle of the machine are the same. This equipment is not a car, after all, in the engine and other aspects of what monopoly technology. So only buy good, do not buy expensive, as for what price can buy, but also your own grasp, I can only say these, in said more than a brick smashed me. If you say less than where please understand, if you are offended hope that peers forgive me.
