When buying a water purifier, do we choose single or dual outlet water?

  Water filtered from water purifiers on the market is generally categorized into two types, purified water and pure water. Among them, pure water refers to H2O without impurities. Tap water is filtered through RO (reverse osmosis) membranes, which can remove heavy metals, organics, scale, bacteria, viruses and other harmful substances, filter out minerals, and turn into pure water. Pure water contains almost no other substances and can be drunk straight.
     In addition, purified water is water that contains no or a small amount of harmful substances. There are two kinds of water purification in the market, one is the water filtered by ultra-filter, the other is also called water purification after PP cotton, activated carbon, these primary filtration of water purification, ultra-filtration to remove harmful substances, the effect of some better. Purified water is not able to drink, generally as kitchen water, used to wash dishes, cooking, soup and so on.

The main difference
 Dual water household water purifier must contain two cartridges, one is ultrafiltration membrane cartridge, the other is RO reverse osmosis membrane cartridge, while the single water is not the same, it is the conventional single water purifier according to type, such as ultrafiltration water purifier does not have RO reverse osmosis membrane cartridge.

     The difference between a dual outlet water purifier and a single outlet water purifier is mainly in the water, single outlet water purifier has only one outlet water, either out of the purified water, or out of the pure water. A dual outlet water purifier has two faucet outlets, one for purified water and the other for pure water. Dual outlet water purifiers actually include the full functionality of single outlet water purifiers, with the addition of water purification.


Price Comparison
In the same category of water purification brands, single outlet water purifiers are cheaper than dual outlet water purifiers, this is mainly because it uses a single filter cartridge, unlike dual outlet water purifiers that require different types of cartridges to work together, so the cost will be higher.

     The benefits of dual water is when washing dishes, cooking needs a lot of water when using water purification without waiting and healthier than tap water, in fact, dual water purifier in the absence of water purification is a single water, that is, dual water is actually completely including the function of a single water, and more water purification, so the same cartridge in the case of dual-water to be a little more expensive than single-water.

Energy consumption comparison
 Single outlet water purifier, it is only a type of water, either pure water or purified water, if it is pure water, then it is that electricity will also produce wastewater, in water-scarce areas is very inapplicable, if it is water purification, then it is that does not require electricity and does not produce wastewater, which reflects a single outlet water purifier in the daily use of a single, which can not be adapted to daily life in the general situation.

     Dual water purifier, it can produce both purified water and pure water, so it can be full of different people's needs, the production of these two kinds of water requires different energy consumption, which can be freely switched according to their own needs, the flexibility to be higher.

How to choose?
First of all, look at the budget

Generally speaking, dual water both water purifier and ultrafiltration machine, need different types of cartridges with the use of single water either water purifier or ultrafiltration machine, the use of a single cartridge, the price is naturally cheaper than dual water, so you can decide according to their actual budget.
Second, look at the family use scene.
If the family is less, less water, then whether it is drinking water or cooking, washing dishes, with a single water is enough, there is no need to separate. If the family population is relatively large, a lot of water scenes, both to drink and cook, then double water purifier is a good choice, both to ensure the quality of drinking water can also ensure that the speed of water is not too slow.
