1. Does the water purifier need to be plugged in?
1, whether the water purifier needs to be plugged in depends on what type of water purifier you buy. There is a kind of water purifier called water purifier, which is usually plugged in. It is a permeable water purifier, which needs to be filtered by power supply to get a function of purifying water source.
If you buy an ultrafiltration water purifier, you don't need to plug it in. Ultrafiltration water purifier is a kind of physical filtration, which is sold online. The price is around 100 yuan, and some even can be bought for tens of dollars. This kind of water purifier looks like a health pot with a filter funnel in the middle. We just need to pour water into this water purifier and let it sink slowly.
3. Bian Xiao suggested that it is best to buy a plug-in water purifier, because the plug-in filter core is relatively clean, and the main thing that is not plugged in is to filter some harmful substances such as bacteria, rust and colloidal sediments. However, there is no way to filter out harmful substances of small molecular particles with ultrafiltration water purifier, because this technology requires electronic filtration and physical filtration cannot completely filter out tiny harmful substances, so the filtered water is still harmful to human body.
