A buying guide for Water Filter

1. The quality and service life of the filter element
For water purifiers, the quality of the filter element is a key factor related to the actual purification effect. When we buy, we must pay attention to how many layers of purification it is, and what is the filtration accuracy. The longer the effective service life of the filter element, the better, after all, it takes money and time to change the filter element.

2. Actual filtering ability
Regarding the evaluation of filtration capacity, we can analyze the filtration technology. For example, look at which sterilization and antibacterial technology it uses, and then see whether it has antibacterial certification given by an authoritative organization. You can also look at the types of harmful substances it can filter and so on.

3. Effluent flow rate
What affects our actual use experience is also the water flow rate of the water purifier, which needs to see whether it can meet the water needs of the whole family. It needs to be explained here that manufacturers usually use xxxG to indicate the speed of their water output. G actually means gallon, and a gallon is about 3.78 liters. 1000G is able to purify 1000 gallons of water in 24 hours. Converted to a flow rate, that's 2.62 liters of water per minute.

4. Wastewater ratio
For reverse osmosis water purifiers, wastewater will be generated in the purification process. The higher the wastewater ratio, the less wastewater is generated and the higher its utilization.

5. Function
Regarding the function, everyone can actually choose according to the needs. For example, if you want to have your own heating function, you want double water outlet function, and so on. Within the selected range, choose the most user-friendly function.
