Reverse osmosis is only one stage in an RO system. RO systems are made up of 5 or 7 stages depending upon the source water chemistry and contaminants present in the water. In an RO system, water is always treated with reverse osmosis in conjunction with prefilters and post-filters. Each type of system contains one or more of the following filters:

1-PP Filter

The Polypropylene filter is a sediment filter cartridge capable of removing everything that you can see with naked eyes. 05 micron filters mean the filter will trap larger particles than 05 micron. Consequently, the water that you ultimately drink or use will be healthier. PP filters will successfully remove sand, silt, dirt, rust, and other sediment particles. As the 05 micron PP filter collects much smaller particles than filters with larger pores, it may clog up quicker. Since PP filters are economically priced, however, replacing the filter and keeping access to pure drinking water is not a problem.

2- CTO Filter

CTO series, extruded carbon block filter cartridges, are made with coconut shell based carbon which creates what many believed to be sweeter tasting water. The unique structure of these carbon block filters is well suited for chemical adsorption, including VOCs, while reducing chlorine and chemicals that contribute to taste and odor. Ideal for Residential service where improving the taste of the water is the Primary objective, where the carbon block filters will offer the most benefits

3- UDF Filter

UDF is carbon that has been treated with oxygen to make it porous, but it has also been broken up into granules to further increase the surface area for chemical bondage to occur. The water passes through the UDF filter, allowing the organic materials and chlorine to effectively bond with the carbon molecules, thus removing these from the water.

4- RO Membrane

Membrane is the heart of the purification system. The membrane having the pore size less than 0.0001 micron is designed to remove everything bigger than 0.0001 microns including the virus and Bacteria. This membranes Technology is same that is used in the bottled Mineral water. This is NSF certified membrane removes 99% Total dissolved solids (TDS) like arsenic, chromium, lead etc. and many more that are hazards for the human health.

5-Post Carbon Filter

This carbon filter is made of high quality activated carbon. It is designed to crisped up the flavor and enhance the taste of the water. As water is stored in storage tank so it finally provide the taste as well as removes any left residual taste or odor.

6-Mineralized Filter

This is the Remineralization filter that add the necessary minerals like sodium, potassium, magnesium and many minerals that are found in natural mineral water and necessary for human health and body growth.

For Long-term drinking water through the filter processing mineralized, regulate body functions, enhance immunity, prevent kidney stones, clean the inner walls of blood vessels, promote metabolism, prevent skin diseases and other features.

7-Alkaline Filter

The Alkaline filter changes the acidic RO water into a perfect Alkaline Ionized Water. Alkaline filter simply gives back minerals such as ionized calcium, magnesium, sodium, potassium ion, which were taken away while purifying the water.
