Why is Chlorine Added to Drinking Water? Is Chlorine Safe?

Chlorine is a chemical that’s commonly used to treat drinking water, and added to already treated drinking water through a process called chlorination. It is effective in killing off bacteria and microbes, helping to improve the safety of the drinking water. A whopping 98% of water utilities in the United States use chlorine.

Chlorine use has significantly reduced the spread of waterborne diseases over the decades, and overall it’s an effective way to treat water. Unfortunately, research is emerging that chlorine might not be as safe as we once thought.

The primary concern is that chlorine may increase the risk of developing cancer. Unfortunately we do not yet have definitive evidence to say if chlorine is safe or not, but it’s certainly something to do your own research on if you have concerns.


Importance of Water Filtration

Taste – Filtered water generally tastes better and cleaner than standard tap water. Chlorine in particular has a very chemical taste to it, that often reminds people of getting a mouthful of pool water. Using a good water filter can help improve the taste and odor of your water – which may just inspire you to drink more of it!

Safety – Tap water can contain any number of potentially harmful contaminants, as well as leftover treatment chemicals like chlorine. Chlorine is widely used because it’s effective at killing bacteria and sanitizing drinking water supplies. Unfortunately, drinking chlorinated water has been linked to an increased risk of certain cancers, as well as several other serious health concerns.

Peace of Mind – Tap quality can vary significantly from town to town. And even if your area has good drinking water, the condition of the pipes leading to your house could also cause contaminants to enter your water! Using a filter is a cheap and easy way to buy significant peace of mind, knowing that you’re consuming clean, safe drinking water.


How We Chose 

Filter Technology – There are several different types of water filters out there. We focused on filtration methods that are effective at removing chlorine. Reverse osmosis appears to be the most effective, but smaller setups and even water pitchers can work, so long as they use advanced multi-stage filtration tech.

Value – We focused on choosing excellent products at fair prices. We certainly didn’t pick the cheapest models out there, but instead focused on products that offered significant value while delivering superior results.

Reviews – To round out our own findings, we researched third party chlorine filter reviews from real customers. This helped us get a better idea of how each filter performed with various water qualities, as well as how long the filters tend to last.

Durability – Although affordable, most of the best chlorine filter options are still a decent upfront investment. So, we focused on models that are built to last for a long time.
