When purchasing a Crystal Water water purifier, it comes with a standard "CTO-grade" carbon filter. CTO stands for chlorine, taste and smell (chlorine, taste, odor). It is the improvement or removal of these parameters that the filter manufacturers guarantee. Typical CTO filters usually have 10μ (0.01 mm) filter pores. We have chosen a filter with 5μ pore size. It provides good flow, vortex and aeration of the water. Smaller filter cartridges with larger filter pores than this for mounting directly on the faucet are among the best-selling filter types on the household market in the world in you.

1. Make sure the water is completely turned off
2. The top part unscrews the blue cylinder
3. The filter is then unscrewed from the underside of the top part 
4. Unscrew the pillar from the filter
5. Take a new Crystal Water filter and fit in the same way in reverse order.

NB! Filters should not be washed, only changed. After prolonged use, the pores in the carbon filter become clogged with impurities and particles, which reduce the effect.

To ensure optimal water quality, we generally recommend 2 - 3 filter changes per year. The amount of organic material and particles in the water can vary greatly from place to place and can affect the number of necessary filter changes. If or when the water flow is reduced, or you see that the filter has become dark/muddy (caused by e.g. organic matter), this is a sign that the filter needs to be changed. A new filter more effectively removes chlorine and other compounds that give the water a bad taste and smell.

NB! The filter should not be washed, only replaced. New filters can be bought at our webshop
