Which is better, white bottle filter or pre-filter?

White bottle filter and pre-filter have their own advantages and disadvantages, and the specific choice depends on personal needs and preferences. There are at least three points about comparison:

1. Functions and uses: The filter of the big white bottle is more powerful. It can not only be used as a pre-filter, but also can connect multiple filter bottles in parallel as needed to provide multiple purification effects. The main function of the pre-filter is to filter out large particles of impurities and protect household equipment.

2. Filtering effect: the white bottle filter adopts disposable filter element, which is more sanitary, does not need to discharge waste water, and has simple installation conditions. The effect of pre-filter on improving water quality is relatively limited.

3. Scope of application: For poor water quality, white bottle filter is more suitable. Pre-filter is suitable for areas with acceptable water quality, and its effect on improving water quality is relatively limited.
