How to choose a countertop water purifier in 2025? The most easy to step on the pit of the water purifier products, countertop water purifier purchase strategy to help you avoid the pit
Today we bring you the purchase strategy of countertop water purifier. Water purifier in the most easy to step on the pit of the product is desktop water purifier, in the end is not IQ tax, applicable to what people use, after reading this dry shopping strategy, I believe you will have the answer!
First, how to determine whether you need to buy a desktop water purifier
principle of work
desktop water purifier principle of work is actually very simple, is the first to the tank with tap water, tap water through the booster pump pressurization through the filtration module, filtered stock of purified water preserved in the pure water tank, and then finally through the instant heating module, refrigeration module to get the water we need!
What is the difference between a countertop water purifier and an undercounter water purifier?
Compared with the undercounter water purifier, the desktop water purifier has two advantages, one is that it can be freely moved and placed in various areas of the house, easy to access. The second is that the drinking water not only has a heating function, but also refrigeration, ice-making and multi-temperature control technology, to deal with milk, tea and other needs, without the need for an electric kettle, one-step; however, desktop water purifiers need to manually connect the water and pour wastewater, which is not as convenient as the under-the-kitchen type of water purifiers. Under-the-kitchen water purifier needs to be reserved in advance of the water and electricity conditions and installation location, can not be moved, but its direct connection to the tap water, filtered through the cartridge to produce a steady stream of clean water, waste water can also be directly discharged, but also to meet the kitchen cooking cooking and other needs.
In general, desktop water purifier is more suitable for home office daily drinking water, kitchen water purifier is used for home cooking, both have their own characteristics, according to the needs of the choice can be.
What kind of people are more suitable to buy desktop water purifier?
Now more and more people pay attention to the health of drinking water, how to determine whether they are suitable to buy under the kitchen water purifier or countertop water purifier. For ordinary families I think the best water purification program is the pre-filter + RO reverse osmosis water purifier, for most families is to use the pre-filter + RO reverse osmosis water purifier under the kitchen. About the pre-filter and under kitchen RO water purifier can refer to the past articles.
The following usage scenarios are more suitable for choosing a desktop water purifier:
First of all, for the rental party, there is no doubt that the direct flush desktop water purifier, plug and play, can be taken away at any time! But if the home is relatively large, to the kitchen line is too long, the home water staff can add a desktop water purifier as a supplement.
Finally, the studio office is also very suitable for the use of desktop water purifiers, more convenient than barrels of pure water, hygiene.
Second, the cartridge selection points
No doubt RO reverse osmosis membrane cartridge is currently the best filtration program, its filtration accuracy of 0.0001 microns, both macromolecular impurities or metal ions can be filtered clean, equivalent to pure water. While other types of water purifiers are not enough precision, filtered water is generally not directly drinkable, it is recommended to boil before drinking.
How to judge the quality of RO membrane?
Judge RO reverse osmosis membrane, usually with the help of desalination rate (expressed reverse osmosis membrane on the removal of impurities in the water) to measure. RO membrane desalination rate if greater than 95% or more, can be classified as good. At present, the market domestic reverse osmosis membrane of the main manufacturers have times Walton, Qinsen, easy membrane. Foreign reverse osmosis membrane brands are: the United States of America's Dow, GE, Hyderabad, Koch, Japan's Toray, South Korea's World Korea. At present, the United States Dow reverse osmosis membrane is recognized as the industry leader, is the most famous water purifier brand of high-end product line choice.
RO membrane flux is not necessary to pay too much attention!
For water purifiers, the size of the RO membrane specification represents the speed of its purification, so the larger the water purification flux the better. Desktop water purifier is often the first water to the pure water tank, and then take water from the pure water tank, so whether the water production speed of 50G or 100G, the difference in the speed of its water is not big. For desktop water purifier water speed, pressurized pump power and the power of the heating module is often a more direct influence, taking into account the demand for silence, pressurized pump power will not be too large, so the water flow is generally not large. In addition, as can be placed on the countertop use of home appliances, desktop water purifier body are relatively small, its heating module is also smaller, the water speed in order to cooperate with it, and accordingly will be slower. Currently on the market mainstream desktop water purifier water speed to meet the basic daily coffee, tea, and milk. Powder drinking needs, consumers do not need to stick to the RO membrane flux size when buying.
How to avoid cartridge assassins?
Avoiding cartridge assassins is actually very simple, you must calculate the cost of use before you buy, so that you can avoid cartridge assassins. For example, I will consider a few points before I buy: How long do I intend to use a machine to replace it with a new one? This depends on the individual. How many times do I need to replace the cartridge in my planned lifetime? This general product has a recommendation, we will be recommended to calculate whether to send the cartridge? Can send cartridges is the best, you can buy at the time of the event, send cartridges really fragrant! The above three points to figure out, a water purifier core cost is very good to calculate.
Third, the heating / cooling module selection points:
heating function:
basic function of the heating body has quartz tube heating, ceramic heating, nano thick film heating and resistance wire heating four different ways. One of the nanometer thick film heating effect is the best, stronger durability.
Refrigeration function:
high-end machine equipped with refrigeration function should first pay attention to the capacity of the ice gallon, ice gallon capacity can ensure that continuous out of ice water, too small can not be continuous drinking.
Refrigeration is generally divided into semiconductor refrigeration and compressor refrigeration
The advantage of semiconductor refrigeration is that the noise is small, the disadvantage is that the temperature is not low enough, generally about 10 ℃, and the refrigeration speed is slow. Compressor refrigeration and refrigerator principle is the same, the advantage is that the cooling temperature is lower, generally about 5 ℃, and fast, the disadvantage is that the noise is larger, if placed in the bedroom is relatively noisy! Desktop water purifier with ice-making function are using compressor refrigeration, the noise is greater. According to their own demand for ice water and ice can be purchased!
Fourth, the water tank selection points
water tank design capacity and structure to determine the experience
water tank capacity:
tap water tank capacity is recommended to choose ≥ 5L (most of the 5L); pure water tank capacity of 1 person use is recommended to choose ≥ 1L, 2-3 people use is recommended to choose ≥ 1.5L, the family of multi-person use is recommended to choose ≥ 2L. pure water tank is removable is very important for easy rinsing!
Waste water filtration:
There are two types of water tanks for desktop water purifiers, “original waste mixing” and “original waste separation”, which have their own advantages and disadvantages. The “original waste mixed”, is the filtration of wastewater and raw water mixed together, non-stop repeated filtration, until the water source can not extract pure water, this filtration method of filtering a larger burden on the cartridge, but produces a high total amount of clean water, suitable for large drinking water family. “
original waste separation ”, refers to the generation of wastewater and the original water separation, this filtration method is more friendly to the filter cartridge, but each time the total amount of clean water produced is low, you need to manually pick up water more frequently. It is recommended to buy according to your own situation and needs! If you have the conditions, buy the “original waste separation” model.
Water tanks are susceptible to bacteria, microorganisms and even moss in a long-term humid environment, so many high-end water purifiers are equipped with anti-bacterial function. You can pay attention to the antibacterial material and sterilization function of the water tank, and some water purifiers use antibacterial material + ultraviolet sterilization to eliminate secondary pollution.
Fifth, the water efficiency level
water efficiency level in the water purifier is the water production rate of water purification, assuming that 100% of the raw water for filtration, can produce xx% of the purified water, producing xx% of the wastewater. Level 1: water yield ≥ 65%; Level 2: water yield ≥ 55%; Level 3: water yield ≥ 45%.
Choose a level on the line, no other choice!
Six, other features:
Multi-file temperature control: at least 3 files (room temperature / milk / water), preferably 1 ℃ fine temperature regulation
Child lock + anti-scald: a must for families with children
Water quality test results (TDS): you can see the TDS test results in the machine, or APP, although it is a small feature, but let people drink water more assured
Mineralization cartridge: strontium-rich, weakly alkaline cartridge to enhance the taste of the tea, more mellow.
Seven, the purchase of budget
200-300 U.S. dollars price: cost-effective choice, refrigeration, heating basic functions are configured, the price of most products only heating, more than 200 U.S. dollars part of the model with refrigeration. Suitable for limited budget or rental housing.
300-500 U.S. dollars price: comprehensive features, water quality/temperature control more accurate, in the previous price point on the basis of balanced progression, most of the products are equipped with refrigeration and heating, very few only heating. Suitable for medium budget families, family use is most recommended at this price.
Price above $500: innovative technology + all-round experience, richer features, suitable for high-demand users
