Household water dispenser above the water purification bucket inside the cartridge how to buy choice?

The water dispenser cartridge is generally a two-layer cartridge (PP + activated carbon), the PP layer is to filter impurities, the activated carbon layer is to absorb the odor in the water (odor is generally caused by bacteria or organic matter in the water).

There are some on the market that only have a PP layer and no activated carbon layer. If you want to buy only the activated carbon layer is good, in addition to the main odor, water dispenser of pure water itself is very clean.

This kind of filter is very small, the cost is about a 10 round less than, there is no need to deliberately buy expensive, the effect is similar, really do not worry about often change is.

Not recommended to drink pure water, too pure, no trace elements, not good for the body.
