PP filter

One look at the filters in our under-sink reverse osmosis system lets you know the state of the water in our tap systems. Often, we hear that the water supplied by the different water providers within the country is safe to drink. That may be true in that it won’t make you sick but is it water you want to drink.

The PP filter in our under-sink RO system filters out sand, rust and larger suspended particles in the water. The filter traps any particles larger than 5 microns. This stage doesn’t remove any of the chemical components of the water, neither does it disinfect.

Granular activated carbon

The second filter contains activated carbon. This gets rid of bad flavors and odors in the water. This filter also gets rid of chlorine that is used to disinfect the water by your local water provider. Corrosive chemicals and pesticides are also filtered out at this point.

CTO filter

CTO stands for Color, Taste and Odor. This filter eliminates any unpleasant odors and flavors. Chlorine that may have passed through the previous filter is removed at this point. This filter has pores of 0.5 microns so most suspended material is removed at this point.

Reverse Osmosis

This is the heart of the whole system. This filter removes all suspended material in the water as well as any dissolved minerals. Bacteria and viruses that may have passed through the previous membranes is caught at this stage.

Post activated carbon

This stage of the process passes the filtered water over natural stone to give the water a pleasant taste.
