Filter element: Most water purifiers on the market are equipped with 3-4 filter elements, which seem to have good filtering effect, but the number of filter elements is large and their service life is short. Some need to be replaced every few months, and some need to be replaced every year. Frequent replacement of filter elements will increase the use cost.
Flux: it refers to that there are 100G, 400G and other different numbers on the water purifier. The flux usually refers to the water purified by the 24-hour water purifier. The larger the flux, the less time to wait, and the higher the price. Families with large populations are suggested to purchase large flux, which makes water more convenient.
Water purifier flow: refers to the water purification speed of the water purifier in unit time. The faster the speed is, the more water will flow out, and the shorter the waiting time for drinking. The water purification flow is related to the total water purification. For example, if the rated total net water volume of a water purifier is 4000L and the net water flow rate is 5L/h, the service life of the filter element of this water purifier is 800 hours, while the rated total net water volume of the other water purifier is not changed to 4000L and the net water flow rate is 10L/h, but the service life of the filter element of this water purifier is only 400 hours; When selecting the water purifier, we carefully compare the water purification flow and the rated total water purification volume when determining the alternative brands, so as to select the water purifier with high performance and price.
Volume: The volume of the water purifier is also one of the aspects to be considered before purchasing. For the water purifier under the kitchen, the space at the bottom of the cabinet directly determines the volume of the water purifier. Before purchasing, it is necessary to measure the area where the water purifier can be placed to avoid the embarrassing situation that the water purifier cannot be installed after purchasing.
