Chlorine is a yellow-green gas with a strong odor, widely used as a disinfectant in municipal water systems. Water travels a long distance from the treatment plant to your home-through miles of pipes, tanks, and storage systems. To prevent bacterial growth along the way, chlorine is added to maintain residual protection.
According to public water standards, the residual chlorine level at the end of the pipe network must be ≥0.05 mg/L to ensure sterilization. However, while chlorine kills harmful bacteria, it also poses potential health risks when consumed or absorbed by the body.
Although chlorine helps keep tap water clean, excessive exposure can irritate and damage human cells. When chlorine reacts with organic matter during boiling, it can produce chloroform, a recognized carcinogen.
Long-term exposure to chlorine-whether by drinking, bathing, or washing-can have the following health effects:
| System | Possible Effects |
|---|---|
| Respiratory | Irritation of nose, throat, lungs; risk of pulmonary edema |
| Nervous System | Dizziness, fatigue, insomnia, memory loss, irritability |
| Digestive System | Loss of appetite, nausea, bloating, liver dysfunction |
| Skin | Dryness, itching, rash, keratinization, brittle nails |
| Cardiovascular | Increased risk of heart disease and hypertension |
| Cancer Risk | Linked to bladder, rectal, and liver cancers |
Even simple household activities expose you to chlorine:
- Washing fruits and vegetables: Chlorine destroys vitamins and minerals, reducing the nutritional value of food.
- Bathing: Studies show that during a hot shower, 40% of chlorine is inhaled and 30% absorbed through the skin, which is 6–8 times higher than what you consume by drinking.
- Cooking: Boiling water with chlorine forms harmful byproducts such as trihalomethanes (THMs), known to cause DNA damage and hormonal imbalance.
Your skin has countless pores and sweat glands, making it a natural entry point for chemicals like chlorine. When you wash or shower with chlorinated water, it penetrates your skin quickly, entering your bloodstream and affecting your overall health-especially in children and those with sensitive skin.
Medical experts warn that long-term consumption or exposure to chlorinated water can increase the risk of:
- Heart disease and atherosclerosis
- Bladder, liver, and rectal cancers
- Anemia and high blood pressure
- Allergic reactions and skin disorders
To truly protect your health, simply boiling water isn't enough. Boiling may actually increase harmful byproducts like chloroform. The most reliable solution is installing a high-performance under sink water filter.
An under sink water filter effectively removes:
- Residual chlorine
- Bacteria and viruses
- Heavy metals and sediments
- Odor and taste impurities
| Filter Stage | Function |
|---|---|
| PP Sediment Filter | Removes rust, sand, and large particles |
| Activated Carbon Block | Adsorbs chlorine, odor, and organic compounds |
| UF / RO Membrane | Filters viruses, bacteria, and heavy metals |
| Post Carbon Filter | Improves taste and water freshness |
This multi-stage filtration ensures safe, clean, and great-tasting water right from your kitchen tap.
