Micron filter is the first stage filter. This filter is placed outside the RO machine. The extent to which dissolved solids, turbidity and micro organisms are removed is determined by the size of the pores. Substances that are larger than the pores in the membranes are fully removed. Micron Filtration is a type of physical filtration process where a contaminated fluid is passed through a special pore-sized spun filter to separate suspended particles from process liquid. It is also used in conjunction with various other separation.

Pre carbon filter weeds out the impurities as much as possible before water passes to the RO membrane. This is mainly because the carbon filters have an advantage of a higher surface area where all the dissolved substances get attracted to the carbon particles on the surface. At this stage, the carbon filter is referred to as a Pre carbon filter. Pre-RO Carbon filter also improves the life of the RO membrane by protecting it from chlorine which is known to damage the membrane by opening its pores. A long life of RO filter means a low maintenance cost for consumers.

Sediment filter, being one of the pre-filters, plays an important role in the initial stages of the filtration process. As the name suggests, a sediment filter acts as a barrier against different types of sediments or suspended solids. It sieves or holds back physical impurities like dust, dirt, sand, silt, clay, and other solid particles. Mostly the particles that are visible to the naked eye are treated by sediment filters during the process of water purification.

A Sediment filter usually acts as the first stage of water purification. Being the first line of defence, its core function is to remove the physical impurities or particulate matter from water. It prohibits all the solid particulate from entering your filtered water and enhances the filtration efficiency of RO membrane.

It is not responsible for changing the taste or smell of water. It is one of the preventive filtration methods and does not remove chemicals, heavy metals, bacteria, viruses, or dissolved solids in water.

An RO water purifier has various filters that eliminate different types of impurities found in tap water through multiple stages of filtration. The most important of these filters is the RO membrane. This membrane is a thin, semi-permeable layer that has minute pores on it to allow only pure water to pass through it. The impure water on the other hand is released out of the water purifier as reject water. The input water is pushed through the RO membrane with a very high pressure. This high pressure ensures that only purified water passes through the membrane. Thus, leaving behind various impurities, salts, heavy metals, chemicals, pesticides, and microbial contaminants on its surface.

After water gets filtered through various purification stages, another layer of carbon filter is added, called as Post carbon filter. Post Carbon filter usually forms the last stages of water purification. This carbon filter purification stage helps in enhancing the quality of the water. It acts as a polisher, further improving the taste of purified water.

Activated carbon used in Post carbon blocks are made of high-quality coconut shell which are manufactured by unique patented technology to provide maximum active surface area for absorption of these impurities. Post carbon block removes chlorine and other contaminants efficiently, till the last drop of purified water.

An RO water purifier which comes along with Post carbon filters is highly recommended for purification of water. Thus, it is important to invest in the right water purification device that could provide safe and healthy drinking water for you and the members of your family.

UV ( Ultra Violet ) purification systems take water treatment to a higher level—providing a safe solution against chlorine-resistant microorganisms such as Giardia and Cryptosporidium which cause thousands of documented health cases each year.

Silver Nano prevents bacteria and algae from building up in the filters.

Nanotechnology is a promising approach to improving the effectiveness of water purification in many areas worldwide. (8−10) Silver nanoparticles (Ag NPs) are of great interest because of their chemical catalytic ability, stability, antimicrobial properties, and low toxicity to humans.

The Explore Inline Water filters reduces dirt, rust and algae as well as removing chemical tastes and odours from drinking water. The WF43 filter includes the addition of Silver nano technology in the filter membrane which interrupts bacterial growth. Silver nanoparticles (AgNPs) are metal structures at the nanoscale. AgNPs have exhibited antimicrobial activities against fungi and bacteria.
