PentaPure 5-step reverse osmosis (RO) purification process is designed to effectively remove impurities and contaminants from water, ensuring that you have clean and safe drinking water. Here’s a breakdown of each step:

1. Pre-Filter (Sediment Filter)

The first stage involves a sediment filter that removes larger particles such as sand, dirt, rust, and silt. This step protects the RO membrane by preventing larger debris from causing damage.

2. GAC Carbon Filter (Pre-Carbon Filter)

For the 2nd stage, PentaPure Granular Carbon  Filter Cartridge Made with laboratory vacuum heated cleaned Activated husk carbon with 100% FDA approved food grade materials Remove Chlorine, Parasites, Pesticides, VOC, Bad Tastes, Odors, Cloudiness, and Industrial Solvents from Water.

3. Activated Carbon Filter (Carbon Block)

In the 3rd stage, an Activated carbon filter is used to remove chlorine, volatile organic compounds (VOCs), and other chemicals that can affect the taste and odor of the water. This is crucial, as chlorine can damage the RO membrane if not removed beforehand.

4. Reverse Osmosis Membrane

The heart of the system, this stage uses a semi-permeable membrane to separate contaminants from water. Under pressure, water molecules pass through the membrane, while dissolved solids, heavy metals, and other impurities are left behind. This step is essential for achieving high purification levels.

5. Post-Carbon Filter

After passing through the RO membrane, water goes through a post-carbon filter. This final carbon stage further polishes the water, removing any remaining tastes or odors, ensuring that the water is fresh and clean before it reaches your faucet.
