🧾 Chlorine Water Filter Buyer’s Guide
Keen to learn more about chlorine filtration before you spend your money? You’ll find the answers to all your questions in this buyer’s guide.
🤔 What is Chlorine?
Chlorine is a chemical element that is used for a variety of disinfection and protection purposes. We use chlorine in our drinking water, certain medicines, household disinfectants, and much more.
🚰 Why is Chlorine Added to Drinking Water?
Chlorine is used as a major disinfectant in public water systems, and can remove pathogens like bacteria, viruses, and protozoa.
Chlorine prevents water from microbiological contamination as it travels through underground systems into our homes. You can learn more about why chlorine is added to drinking water here.
☠️ Is Chlorine in Tap Water Safe or Dangerous?
The Environmental Protection Agency says that a maximum of 4 PPM (parts per million) of chlorine is safe in drinking water.
Water would actually be less safe if it didn’t contain chlorine, as there would be nothing to kill dangerous, disease-causing pathogens like bacteria.
However, even if low levels of chlorine are considered safe in water, that doesn’t mean that chlorine is necessarily healthy or enjoyable to drink.
Chlorine can give water a chemical taste and smell that many people find unpleasant.
There are also some studies that suggest that chlorine might be more dangerous than we think it is, such as this study, which found that chlorine in drinking water can produce cancer-causing toxins.
Chlorine Effects on Skin and Hair
While the dangers of drinking chlorine in water are widely disputed, there is more evidence to suggest that chlorine can have effects on our skin and hair.
Chlorine can be damaging to the skin, especially if it lingers on our skin after a shower or bath. Chlorine strips the natural oils from the skin’s surface, causing dryness and irritation.
One study even found that a combination of water hardness and chlorine could cause atopic dermatitis, a painful condition that causes itchy, cracked and sore skin.
Chlorinated water can also have a damaging effect on hair. Chlorine interferes with the scalp’s ability to moisturize hair, leaving dry and brittle hair and promoting itching and dandruff. Chlorine can promote fading in dyed hair, and, because it dries out hair, can accelerate hair loss.
⚙️ How a Chlorine Filter Works
There are several types of chlorine water filter, which I’ve covered in more detail below. The type of filter will affect the exact filtration process that takes place.
In a traditional filter, water will pass through a filtration media and certain contaminants, including chlorine, will become trapped in the media’s pores.
Other types of chlorine removal systems may use different techniques to remove chlorine, such as boiling water and treating water with UV light.
🔠 Types of Water Treatment Systems That Remove Chlorine
The most effective types of water treatment systems for removing chlorine are carbon filters, reverse osmosis systems, UV lamps, and distillation units.
Activated and catalytic carbon filters are some of the most affordable options for removing chlorine from municipal water.
These filters have large surface areas and trap contaminants in their media, in a process known as adsorption.
Chlorine particles are bigger than water particles. This means that, while water can pass through the filter, chlorine is blocked from passing any further.
While activated carbon filters are still a good choice for removing chlorine, catalytic carbon water filters are better, as they have a larger surface area that can trap more contaminants at once.
Reverse osmosis is one of the best all-round water treatment options, removing more than 99.9% of all water contaminants, including chlorine.
Reverse osmosis systems may be installed underneath your kitchen sink or on your kitchen countertop, depending on the style of the unit.
There are several filtration stages involved in a reverse osmosis system, including a carbon filter and a semi-permeable membrane. This membrane has tiny pores that allow only water particles to travel through.
This gives reverse osmosis systems the ability to remove a broad range of contaminants, trapping particles that are bigger than 0.0001 microns in size.
No matter what reverse osmosis system you buy, it will waste some water during filtration. This is the biggest downside of the reverse osmosis method of filtering tap water. However, the more modern reverse osmosis systems are far more efficient and less wasteful.
Most people don’t know that you can use UV light to remove chlorine from water. UV purification is primarily intended for killing disease-causing microorganisms, like bacteria and viruses. It does so by producing ultraviolet rays with wavelengths of up to 400 nm.
These wavelengths don’t only kill microorganisms. They also produce chemical reactions that can remove up to 15 ppm of chlorine or chloramine in water.
A UV lamp may be used alone or as an add-on to a more comprehensive filtration system. UV purification can’t filter out contaminants, so it’s only suitable for targeting chlorine and microorganisms.
While most water filters will become damaged by too much chlorine, UV lights won’t be affected by higher chlorine quantities.
UV lights usually have a lifespan of 1 year. After this, you’ll need to swap out the lamp with a new one.
Distillation is another method of purifying water. A distillation system is highly effective in removing almost every contaminant in drinking water, including chlorine.
During the distillation process, water is heated in a boiling tank until it evaporated. This water travels along a cooling corridor, causing the water to condense. Condensing is a lengthy process, and water droplets are formed drop by drop. The condensed water collects in a clean container.
Chlorine can be evaporated by boiling, but it can’t condense at the same temperature as water. This means chlorine particles can be effectively removed by distillation. Any chlorine that manages to condense with water will be filtered out when water passes through a carbon filter in the distiller’s spout.
The majority of other contaminants, such as pesticides, lead, and bacteria, also can’t evaporate with water. These contaminants are left behind in the boiling chamber, and can be washed away during cleaning.
💭 Considerations When Purchasing a Filter to Remove Chlorine
Before buying a chlorine water filter, it’s worth considering the following factors:
Why do you want to buy a chlorine water filter? Do you want to remove chlorine from just your drinking water? Or do you want to eliminate chlorine from your whole home water supply? Perhaps you just don’t want to shower in chlorine?
Your chlorine removal requirements will determine what type of chlorine water filter is suitable for you. There are three types of applications for removing chlorine: a whole home filtration system, a drinking water filter, and a shower water filter.
- Whole home water filters connect to your home’s water supply and provide clean water to your home’s appliances, faucets and showerheads. Your clothes and dishes will be washed in chlorine-free water, and you can shower in water that doesn’t contain chlorine. Your drinking water will also be free from chlorine.
- Chlorine drinking water filters remove chlorine from the water you want to drink. A water filter pitcher, under-sink unit, and faucet filter can all be used to remove chlorine from your drinking water.
- Showerhead filters connect onto your existing shower line, or are installed in place of your shower head, and filter out chlorine from your shower water.
The type of filter application you decide on will depend on why you want to remove chlorine from your water.
A filter’s capacity is a measure of how much water it can produce per day, in gallons per day. The bigger the filter capacity, the more capable it is of producing higher volumes of water. However, bigger isn’t always better.
Your chosen filter’s capacity should be high enough to provide an on-demand supply of chlorine-free water whenever you need it. Getting a filter with the right capacity is more important for whole-home water filters. A filter capacity that’s too small could mean that the filter can’t keep up with your demands. As a result, your water pressure could drop significantly.
To work out the filter capacity you need, find out how much water your family uses per day. If you have a smart meter, work out a daily average from your readings over a week. Compare your daily water usage to the maximum filter capacity in GPD, and choose a system that provide slightly more water than you need.
Filter capacity is less complicated with point-of-use filters. Showerhead filters are designed to deliver a constant stream of water.
As long as your home’s water pressure is high, you will get enough water from a showerhead filter. However, these filters can have shorter lifespans than whole-home filters.
Drinking water filters may be disconnected from your water supply. In this case, your filter will need refilling with water every time you use up the filtered water supply. The larger the filter’s holding capacity, the fewer times you’ll need to fill it up.
A drinking water filter may be connected to your under-sink water supply. Capacity is more important here – but the majority of filters are capable of delivering enough water for your drinking requirements.
Flow rate ties into capacity. The more filtered water a system can deliver per day, the higher the flow rate.
Again, flow rate is most important on whole-home water filters. These filters need to deliver water quickly enough to supply multiple appliances at once, such as your shower, your washing machine, and your dishwasher.
Systems are typically sized between 5 and 14 GPM. The average-sized home with 1-2 bathrooms will be fine with a system with a 7-10 GPM flow rate.
A shower head filter should be designed to filter your water without interrupting flow, though some can be better than others. If you have power shower, you’ll need to read customer reviews and find a chlorine filter that can deliver a high water pressure.
The flow rate of a drinking water filter system depends on what type you opt for. A water filter pitcher, for instance, uses gravity filtration, and will take the longest to filter water.
Filters powered by electricity or water pressure, on the other hand, will have a faster water flow, and will be able to deliver water almost instantly.
Water filter manufacturers can apply to get their filters tested and certified by NSF International, an independent certification organization.
If a water filter has an NSF certification, it tells you that the filter lives up to its performance claims regarding the removal of specific contaminants.
There are several certifications you can look for in a chlorine water filter:
- NSF 42 – this is the main certification to look out for, as it indicates that a water filter has been tested and certified to remove chlorine, taste and odor.
- NSF 53 – indicates that a filter is capable of removing health-hazardous contaminants, like lead. Many filters with an NSF 42 certification are also NSF 53 certified.
- NSF 58 – reverse osmosis systems that reduce water’s TDS by at least 75% can obtain an NSF 58 certification.
It’s not essential to look for a water filter system that has an NSF certification, but you may feel more comfortable investing in a certified system. Be aware that filters that are “tested to NSF standards” aren’t actually NSF certified.
Installation & Maintenance
The type of chlorine water filter you buy will determine its installation and maintenance requirements.
Whole-home chlorine filters require the lengthiest, most challenging installation. You’ll need to cut into your water line and install the system so that it intercepts your water flow. You may also need to install a bypass valve to send water around your filter when you’re performing maintenance.
Showerhead chlorine water filters are typically very easy to install: you simply screw the filter in place on your shower line and run water through it to prime the filter.
Installing an under-sink drinking water filter can be slightly more complex, as again, you’ll need to cut into your water line. Standalone filters like water filter pitchers require no installation at all.
To maintain a filtration system, you will need to change its filters. Systems with multiple filters will cost more to maintain than single-filter systems in the long run.
Some systems require more frequent filter changes than others. If you want to avoid maintenance as much as possible, look for units with a filter life of half a year or more, or systems with a filtering media, which tends to last longer.
❔ Frequently Asked Questions
Is it true that chlorine evaporates if you leave it long enough?
Yes. If you want to remove chlorine at no cost at all, you can let it sit in a water pitcher overnight. By the morning, the chlorine should have mostly evaporated from your water.
There are a few setbacks to chlorine evaporation. For one, you can’t measure how much chlorine has evaporated from your water, and how effectively the process works. Secondly, if you want immediate access to water that’s free from chlorine, that won’t happen. You’d have to think ahead and plan to store your water at least 8 hours before you wanted to drink it.
Does boiling water remove chlorine?
Yes. Boiling water speeds up the chlorine evaporation process. Chlorine is one of the few impurities that will evaporate from water when boiled.
Again, this process costs nothing. However, boiling your water before drinking can be a chore, and you’ll need to wait for the water to cool before you can drink it. You also can’t determine how long to boil water for effective removal of chlorine.
How much chlorine can a water filter remove?
A typical chlorine water filter can remove between 90 and 99% chlorine from water. It’s rare for a filter to remove 100% chlorine. However, even a filter that removes 90% of chlorine will eliminate the chlorine smell and taste from your water.
Is it safe to remove chlorine from water?
Yes. Although chlorination removes harmful microorganisms from your drinking water, a chlorine water filter will remove chlorine without reintroducing these microorganisms. The chlorine has already done its job, and it is no longer needed by the time you come to drink your water.
Can a water softener remove chlorine?
No. Water softeners use ion exchange to swap out hardness minerals (calcium and magnesium) with sodium. Water softeners can’t remove chlorine.
