The following are things worth considering before you go out and hunt for the best water filter to remove chlorine. These are also the very same criteria we focused on when picking our top products for this guide.
Before you even think about buying a chlorine filter, you should have your water tested to determine the level of chlorine as well as other contaminants in your tap water supply.
Only with this information at hand can you choose the most appropriate filter system.
NSF testing and certifications are your only guarantee that a water filter performs as advertised by the company behind it.
NSF International is an independent institution that establishes public health and safety standards which products like water filters can be verified against.
For chlorine water filters, look for NSF Standard 42. Shower filters that remove chlorine are tested according to NSF Standard 177.
As a tap water contaminant, chlorine is one of the easiest to remove. Thus, you have a large selection of water filter types and models. Above, you’ll find a selection of the best products from each category.
All water filters, but whole house water filters in particular, need to be capable of providing enough water within a given time period. This is determined by a filter’s flow rate.
A water filter that’s too slow processing the water may lead to extended waiting times or a drop in water pressure.
As far as filtration capacity is concerned, filter cartridges with a long service life save you from frequent replacements which is more convenient and often also more affordable.
How much time and effort goes into installing and maintaining a water filter primarily depends on its type. For example, whole house water filtration systems are certainly more difficult to get up and running than a simple water filter pitcher.
It can take a while to find a good water filter that can remove chlorine effectively, even if you have a flexible budget. In fact, that can make your search a bit more complicated, because it would often prompt you to judge products based on their price alone. But as our experience has shown, that’s not a good idea for a variety of reasons.
Instead, we use a special list of comparison criteria to ensure that each filter we’re reviewing is worth your money and brings something useful to the table. We also collected as much information as we could about each of those products, going to different sources in the process (manuals, user ratings, etc.).
Those sources included the manufacturers themselves occasionally. We learned early on that talking to companies can provide us with a lot of valuable additional information about their products and services.
And in the end, nothing beats personally reviewing a product when you want to be as objective as possible about it. That’s exactly what we did, and it’s allowed us to make our reviews more factual than many others.
More on Chlorine Water Filters
Simply put, chlorine is added to U.S. tap water supplies for disinfection. In other words: To kill parasites, bacteria, and viruses that could otherwise cause diseases.
Thus, water chlorination makes water safe to drink. Introduced in 1908, it has helped to eliminate waterborne diseases like typhoid fever saving tens of thousands of lives.
Furthermore, it is estimated that municipal water chlorination “played a major role in increasing Americans’ life expectancy by 50 percent during the 20th century”. The CDC calls it “one of the most significant public health advances in U.S. history”.
And lastly, chlorine also helps to reduce unpleasant tastes and odors.
Chlorine levels up to 4 ppm are considered safe in drinking water.
Also, the benefits of water chlorination far outweigh any health risks from possible disinfection byproducts, which form as an unintended consequence of adding chemically-reactive chlorine to water containing small amounts of organic matter.
Still, there are risks associated with these byproducts. Among the most critical are trihalomethanes, or short THMs. Studies showed that lab animals exposed to very high levels of trihalomethanes had an increased risk of cancer. Studies on humans found a link between long-term exposure to high levels of chlorination byproducts and a higher risk of cancer.
THMs may also have an effect on pregnancy. A study found that pregnant women who drank large amounts of tap water with high THMs had an increased risk of miscarriage.
That being said, we want to stress that the aforementioned studies neither prove a link between chlorination byproducts and cancer nor between CBDs and miscarriage. They simple show a need for further research.
Chlorine can affect the outer layer of your skin stripping it from its natural oils causing dryness, itchiness, and even rashes. This may even lead to premature aging.
The same applies to your hair. Without its natural oil, you hair may become brittle. Plus, chlorine can change your hair’s natural color.
Filtration is the most straightforward approach to removing chlorine from water. There are two ways you can approach this:
When you consider that a large proportion of our daily exposure to chlorine and its disinfection byproducts does not come from the water we drink, but from what our skin absorbs and our lungs inhale in the shower, going the POE route makes a lot of sense.
Second, no matter what type of chlorine water filter you choose, what’s important is that it utilizes at least 1 activated carbon filter block or granular activated carbon filter stage (catalytic carbon filters work as well).
As a filter medium, carbon adsorbs up to 99.9% of free chlorine and many other natural and synthetic contaminants from water and traps them in the tiny pores on its surface.
Thereby, chlorine removal is a function of contact time with the filter medium. In other words: When it comes to carbon filters, appropriate sizing is critical. The more water that needs to be processed within a given period of time, the larger the filtration system needs to be.
A viable but less common alternative to carbon filtration is UV light water treatment. Broad-spectrum ultraviolet systems reduce chlorine and chloramines into easily removed byproducts.
How? Wavelengths between 180 nm and 400 nm trigger a photochemical reaction that dissociates free chlorine forming chloride ions/hydrochloric acid.
Simply put, distillation provides water of the highest purity. Chlorine stands no chance of surviving the water treatment process, provided that there is a way for the gas to escape.
The reverse osmosis membrane itself is not suited for filtering chlorine. In fact, chlorine causes damage to an RO membrane.
Fortunately, every single reverse osmosis system we reviewed applies at least 1 carbon pre-filter to eliminate most of the chlorine before it gets the chance to even touch the reverse osmosis membrane.
Yes, they do.
Comparing the three, the Brita Standard is the least effective and lasts for a mere 40 gallons. Brita Longlast and Brita Complete are similar in terms of contaminant reduction rates and filtration capacity. One Longlast cartridge can treat up to 120 gallons of drinking water. Complete replacement filter elements are good for 100 gallons.
PUR’s Basic and Lead Reduction pitcher filters remove at least 96.9% of chlorine. The PUR faucet mounted filter removes about 96% chlorine plus 99.7% THMs, a group of harmful disinfection byproducts.
As far as ZeroWater is concerned, the filter pitcher reduces 97.4% of chlorine, according to a test conducted by NSF International. It’s also known for removing more than 99% of TDS (Total Dissolved Solids). However, the handling is rather difficult. And it’s one of the slowest pitchers you can buy with a low filtration capacity so that replacement cost will add up quickly.
Does boiling water remove chlorine? Yes, you can boil chlorine out of water, although the term boiling might be misleading. It’s enough to heat up the water, no need to actually boil it.
How long does it take for the chlorine to dissipate? Simply heat for 10 to 20 minutes and voila, all chlorine will be gone. (The exact time required could be much lower depending on the amount of water and chlorine concentrations.)
Yes, chlorine as a gas at room temperature is a volatile solute that evaporates from water over time, escaping into the surrounding air.
How long does water need to sit to dechlorinate?
This depends on water temperature and surface area, air temperature, and the level of dissolved chlorine. For example: If you put a large but very flat bowl of chlorinated tap water out in the sun, the dechlorination process will be much faster than if you were to put a glass of the same amount of tap water in your refrigerator.
By the way, apart from UV light, aeration and circulation can speed up the process.
Generally speaking, you should let the water sit for about 24 hours, although chlorine taste and odor might have vanished after a couple of minutes. For more control over the process use chlorine test strips to determine how much of the water disinfectant is left.
Your last option is to use a dechlorination agent, short dechlorinator, a.k.a. chlorine neutralizer or chlorine remover.
There are different chemicals available including potassium metabisulfite, sodium thiosulfate, sodium sulfite, and vitamin C.
The main benefit of using a dechlorinator is that it works relatively fast. Required contact time: A mere seconds up to 5 minutes.
