Sediment Filters :There are sediment cartridges to trap the fine particles of sand and silt and carbon fines. In RO (Reverse Osmosis) systems, these are regarded as the pre-filters. Depending upon the application, they come in variety of micron ratings.

Taste and odour cartridges :These filters contain activated carbon that removes chlorine and organic matter as these things make water less tasteful to the consumers. These pre-filters in RO purifiers protect the RO TFM membranes from chlorine damage.

Reverse Osmosis: Reverse Osmosis removes the dissolved impurities from water with the help of a semi-permeable membrane. It reverses the flow of water from high salinity to high purity.It permeates the water flow on opposite side of the membrane.If you are having hard water in your home, you absolutely need a RO water purifier in your home. However, this filter completely de-mineralised the water. Along with undesirable minerals, it removes healthy minerals also.
