What is the difference between direct drinking machine and water purifier

When many consumers intend to use water purification equipment, they often fall into a difficult choice in the choice of water purification equipment. That is, is the water purifier useful? Is the direct drinking machine good or the water purifier good? What is the difference between the direct drinking machine and the water purifier? There are some people in the market who say that the water purifier is good and some approve of using the direct drinking machine.

At present, there are so many kinds of water purifiers in the market, which has made consumers feel distressed about their choice. Now there are direct drinking machines, which make consumers not know how to choose. What is the direct drinking machine? Is it a water purifier or a direct drinking machine? What's the difference between the two?

First of all, let's understand the water purifier we are familiar with. Although there are many kinds of water purifiers, the main ones are ultrafiltration water purifier and reverse osmosis water purifier.

The core filter element of ultrafiltration water purifier is ultrafiltration membrane, and the pore diameter range of ultrafiltration membrane is 0.1-0.111 μ M. Bacteria, sediment, macromolecular organic matter, rust and so on in water can be intercepted by ultrafiltration membrane. However, dissolved odor, pigment, organic matter and inorganic matter in water can pass through the membrane together with water molecules. If you know that you can use this kind of water with good quality, it is not recommended to drink it directly.

The principle of reverse osmosis is a popular water purification method in the world. The core element of reverse osmosis water purifier is reverse osmosis membrane with a pore diameter of only 0.0001 μ m, and even a very small virus has a diameter of 0.2 μ m, so they cannot pass through the reverse osmosis membrane. In addition, heavy metals, inorganic salts, organics and bacteria dissolved in water can not pass through the reverse osmosis membrane. After RO membrane, the water can reach the standard of direct drinking.

See here, you should understand that the so-called direct drinking machine is only one kind of water purifier, that is, the water purifier that can achieve direct drinking is called direct drinking machine, that is, the common and popular reverse osmosis water purifier in the market. Although some direct drinking machines have heating or ice making functions. In fact, there is no substantial difference in the current name. The key is the filtering system and the function you want.
