Should we change the water filter fridge every 6 months?

Who! Once the filter was soaked in water during its initial use, it must be replaced within 6 months, unless otherwise indicated.

Why?

Over time, as the filter adsorbs and retains the pollutants in the water, it freezes, thus reducing water circulation and filtration capacity. The most serious is that new bacteria begin to block the filter, which increases the risk that these bacteria are found in the water you drink. This is also true for the ice dispenser, since some bacteria are resistant to freezing temperatures, and therefore, even ice can be contaminated.

Water filters trap contaminants mechanically, which means that contaminants physically larger than the pores of the filter are trapped. Other contaminants are adhering to the surface of coal by catalytic reduction. If this coal is saturated, contaminants can not be adsorbed. If the filter pores are saturated, the water circulation and filtration capacity of the filter are reduced significantly.

While it is easy to notice a decrease in the flow of water, it's not as easy to tell when the carbon surface filter is saturated and needs to be changed. Do not change the water filter cartridge carries the risk that bacteria and other contaminants are found in the water you drink.

Most water filter cartridges are composed of finite life. The life of a cartridge depends on the filter model, it is specified in the manufacturer's instructions. However, longevity is announced calculated based on volume (liters) that can handle a cartridge and / or number of months of use. Cartridges must be changed according to manufacturer's recommendations so that the filtering system works properly.
