How to Remove Chlorine from Water

How to Remove Chlorine from Water
Published on 11/4/2016

Chlorine is a powerful disinfectant popularly used in municipal water treatment plants to eliminate bacteria and other potential harmful microorganisms. It is highly effective at eradicating waterborne diseases and killing pathogens. Chlorine is widely used across the world as a disinfectant as it is inexpensive, widely accessible while being easy to control and monitor. However, despite its effectiveness and its ability to disinfect water, chlorination is a problem on its own and has several negative effects.

Negative Impacts of Chlorine on Health

Chlorine-contaminated water can lead to a number of health risks:

  • Increases risk of cancer
  • Promotes cell damage
  • Increases risk of cardio-vascular diseases
  • Increases risk of asthma

Aside from these health risks, chlorine contaminated water is the primary cause of bad taste and odor in drinking water. The unpleasant taste may encourage your children to opt for less healthful and better tasting drinks to hydrate and refresh themselves, such as artificial store-bought juices, soft drinks and iced tea. The decreased intake of water can have a detrimental impact on their health, causing them to tire much easily.

How to Remove Chlorine

To help you protect your family against the dangerous side effects of chlorine, we have compiled a detail guide to get you started.

The number one method to remove chlorine from drinking water that's used is basically all water purification applications is Granular Activated Carbon.

Chlorine Gas in the Shower

Did you know your body absorbs substances while showering? Unfortunately, about 60% of the chlorine most people absorb every single day is a result of showering in chlorinated water. Not only does chlorine damage your hair and skin, resulting in an unappealing appearance, but it is also detrimental to your health.

Steamy showers open the pores of the skin, allowing vaporized chlorine (in a now more concentrated gas form) to enter the body, resulting in itchy, dry and irritated skin. Long-term exposure to vaporized chlorine in the shower can have harmful effects on your health as well resulting in conditions such as asthma, kidney damage and since chlorine is a well-known carcinogen, probably even cancer.


  • Carbon Shower Filters

Installing carbon shower filters is the most effective way to remove chlorine from showered water. Installing a shower filter will prevent your family against the dangers or chlorine contaminated water. These filters absorb chlorine without leaving behind any negative effects on your water supply. Carbon effectively eliminates the bad taste and odor from the water supply, resulting in clean, filtered water that is safe for your family. Apart from a shower filter, you may also opt for a heavy-duty carbon filtration system for your home’s water supply that will deliver clean and filtered water in every outlet of your home.

Chlorine Water in Pools

Indoor swimming pools are difficult to manage. After all, pool chemistry is not easy to comprehend. Too much chlorine in your pool can indeed be dangerous. Over exposure to chlorinated water can result in lung irritation, asthma and skin problems. High chlorine levels bring down the pH of the water, making it more acidic. Not only is this detrimental for your health but it can also cause damage to the pool equipment and concrete surface. High chlorine levels can also promote the corrosion of metal piping. If your pool features a liner, the acidic water can damage it as well.


  • Do Not Add Too Much Chlorine

If the chlorine reading is a little over 3ppm, stop adding more chlorine to the water. If you are using a chlorine feeder or a chlorinator, turn it off. In case you are using a chlorine floater, remove it from the pool. Once the swimmers jump in, the de-chlorinating effect will initiate itself.

  • Use UV Rays to Disinfect the Pool

UV rays from the sun will rapidly break down chlorine molecules in the pool. On a bright sunny day, uncover the pool for a couple of hours and let nature work its magic. Leaving the pool uncovered on a single cloudless afternoon for a couple of hours can eradicate at least 90% of the pool’s chlorine. Using natural sunlight is a better alternative to using ultraviolet lamps.

  • Adding Chlorine Neutralizing Chemicals to the Pool

This is an effective solution in case you have added too much chlorine in the pool. The two must common and tested chlorine neutralizing chemicals in the market are Sodium Sulfite and Sodium Thiosulfate. Other alternatives include Sodium Metasulfite and Sodium Bisulfite. These chemicals can easily be found in the market and are inexpensive compared to commercially sold chlorine neutralizers in stores.

Follow the instructions carefully and take precautionary measures when using chemicals. Also, store the disinfectants and neutralizers away from children.

Chlorine Contaminated Drinking Water

Several laboratory tests have highlighted the long-term negative effects of chlorine on your health. Excessive use of chlorine contaminated water can result in the following hazards:

  • Increased risk of bladder cancer
  • May result in imbalance of lipid levels in the body
  • Drinking chlorinated water can increase the risk of asthma
  • Overexposure to chlorine-contaminated water can elevate cholesterol levels in the body.
  • Install Carbon Filtration System To Your Home’s Water Supply


The easiest and most effective method to remove chlorine from your home’s water supply is to install a carbon filter dechlorination system. Depending on the size of your house, you can either opt for our Whole Houser Water Filter 20 and Triple 20 that is suitable for smaller apartments or home or invest in a much bigger and high powered system, such as the Eagle 1000 or Big Blue High Flow Whole House that filters 6 to 10 gallons per minute.

  • Use Vitamin C Tablets

Using Vitamin C tablets is an inexpensive method to dechlorinate water supply. Depending on the brand, a single tablet can effectively treat around 100 gallons of water. Such tablets work best for hot tubs and bathwater.
