Styrene, also known as vinyl benzene or phenyl ethene, is an organic compound with the chemical formula C6H5CH=CH2. It is a colorless liquid, lighter than water, insoluble in water, easily evaporates, and has a sweet odor when dilute but an unpleasant odor when concentrated. Styrene is used in the production of polystyrene and various other polymers.

What is Styrene?
Styrene, also known as vinyl benzene or phenyl ethene, is an organic compound with the chemical formula C6H5CH=CH2. It is a colorless liquid, lighter than water, insoluble in water, easily evaporates, and has a sweet odor when dilute but an unpleasant odor when concentrated. Styrene is used in the production of polystyrene and various other polymers.
Styrene is used in foam and contributes to cancer development, reduces vision, hearing, and causes nerve damage.
Effects of Styrene on Health
Short-term exposure to styrene can cause:
– Irritation of the eyes, skin, and nose
– Digestive effects
– Respiratory effects
Long-term exposure to styrene can cause:
– Central nervous system and kidney effects
– Headaches
– Fatigue
– Hearing loss
– Balance and concentration issues
– Cancer

How to effectively filter styrene contamination in water?
The U.S. Environmental Protection Agency (EPA) recommends using granular activated carbon. Granular activated carbon is a versatile solid material with multiple pore sizes (small, medium, large). Particularly, the small pores of activated carbon effectively adsorb small molecules of volatile substances like styrene. Additionally, activated carbon also has excellent adsorption capabilities for chlorine (used for disinfection in tap water). Therefore, water filtration systems with activated carbon filters are widely used in household water filtration or treatment systems.

Choosing the right water filtration system for your family
Reverse Osmosis (RO) water filtration systems are considered the most effective but may remove essential minerals from water. With RO membranes, the resulting water has a very low Total Dissolved Solids (TDS) level, usually below 10. This means many beneficial minerals in the water are also removed.
To address this issue, Kangaroo's KG100HU and KG100HU+ water filtration systems use a 5in1 filter after the RO membrane to replenish essential minerals for the body, remove oxidizing agents, create alkaline water for better taste, and add negative ions to the water.
Does RO water filtration waste water?
RO technology is a water filtration technology that uses membranes with filter sizes of 0.0001 micrometers. Besides filtering solid particles and heavy metal ions, it can also filter microorganisms, bacteria, etc., with extremely small sizes. It provides drinkable water without the need for boiling.
The previous drawback of RO water filtration systems was the high wastewater ratio, typically 1:3, meaning for every cup of pure water produced, 3 cups of wastewater were generated. The KG100HU and KG100HU+ products utilize Voltext technology made in Korea, reducing wastewater by up to 75%. Now, to obtain one cup of pure water, only one cup of wastewater is produced, at a ratio of 1:1.
According to Theperfectwater, activated carbon filtration systems can also remove styrene – one of the organic pollutants found in water contaminated by oil spills from the Da River water plant in recent days. Some users of RO water filtration systems with activated carbon filters in Hanoi also reported that the treated water no longer has the oily smell of water from the plant.
