Best Water Filters for Chlorine

I applaud you if you have chosen to add a water filter to protect your family from ingesting excessive amounts of chlorine because it’s a substance that has been used to treat your local water supply.

I will even help with that process by going over with you several of the best water filters for chlorine removal.

A list that I have come up with by doing extensive research on water filters and combining that with my extensive knowledge on the characteristics of chlorine and how it’s used as a sanitizer.

This is something that I learned well during my 26-years doing swimming pool water chemical balancing and filtration.

I will even give you several reasons why my top pick for removing a significant amount of chlorine from your drinking water is the Springwell CF1 Whole House Chlorine Filter.

Evaluation Criteria

Here are the traits of filters that remove chlorine that I would recommend taking a closer look at when shopping for one.

Percentage of Chlorine Removed or Reduced

If you are purchasing a water filter to remove chlorine from your drinking water, then you better be aware of exactly how good a filter is at doing that.

Chlorine Filtration Method

This is what type of filtration media inside of a water filter is responsible for removing or reducing the chlorine that passes through it.

NSF/ANSI Standard 42 Certification

NSF/ANSI are very well-respected independent testing groups. When a water filter or device has been certified to be NSF/ANSI standard 42 compliant, that generally means it does a good job of eliminating chlorine taste and smell. .

Other Contaminants Removed or Reduced

It’s a nice bonus if the water filter that you purchase to remove chlorine does much more than just that. Especially if it does not significantly increase the price of the unit.

Filtration System Placement

There are two ways that water filters can be installed. These are point of entry water filters that will treat 100% of the water that comes into your home and point of use systems that will only treat the water that you use for cooking, making ice, and drinking.

Best Water Filters for Chlorine Reviewed

In my opinion, these are the best choices of filtration systems when it comes to chlorine removal.

#1 Springwell CF1 Whole House Chlorine Filter

Springwell CF1 Whole House Filter

That’s because it not only filters a significant amount of chlorine out of tap water but it will also perform this operation for 100% of the water that comes into your home.

That means it will not only keep you from ingesting large amounts of chlorine but will also help prevent this chemical from doing such things as drying out your hair and your skin. As a bonus, it will filter out many other water contaminants besides chlorine too.  

It’s also a single tank whole house chlorine water filter that makes for an easy DIY installation and the fact that it needs very little maintenance over its expected 10-year lifespan means it’s a great deal despite its high initial cost (currently $772.98 without add-ons).

clearly-filtered-pitcher

#3 Clearly Filtered Under Sink Filter

clearly-filtered-under-sink

If you do not want to clutter your counter space with a somewhat unsightly water filter that removes chlorine, then this under sink water filter will appeal to you. That’s because a reverse osmosis water filter works well at removing chlorine but stays out of sight while doing it.

#4 Aquatru Countertop RO System

aquatru

Reverse osmosis filters alone do not make for great chlorine water filters but when you combine RO filtration with a good activated carbon filter stage such as this system does, then you have a powerful water purifying machine.          

This 4-stage Aquatru Countertop Reverse Osmosis System will remove over 80 drinking water contaminants and that includes a very substantial 99% of the chlorine that passes through it.

It’s a fully-contained water purification system that all you have to do to get it going is wipe it down, plug it in, and then fill it up with water. This water filter will do the rest on its own.

That level of automation combined with its effectiveness somewhat justifies its high initial cost and somewhat pricey replacement filters.

On average its filters need to be changed out every 6-months with the lone exception being its RO filter which should last you 2-years.       

Main Features and Benefits 

Percentage of Chlorine Removed or Reduced: This unit does a real nice job eliminating some of the most common contaminants in drinking water including 98% of the chlorine that passes through the 4 filtration stages.    

Main Filtration Method: Even though this has a great working reverse osmosis membrane inside of it, the activated carbon pre-filter inside of it is what does the work when it comes to chlorine removal.     

NSF/ANSI Standard 42 Certification? Yes, and a whole lot more to include NSF/ANSI standard 53, 58, 401, 473 certifications.  

Other Contaminants Removed or Reduced: This is yet another water filter on this list that will do a whole lot more than just remove chlorine. That includes removing 99% of benzene, 98% of arsenic, and 99% of lead among others.

It can be set up and working in less than 5-minutes and there is not much fuss when it comes to maintenance either. Drawbacks to it are its somewhat pricey initial cost and the fact that it has to be hand filled but after that, everything else about it is only positive.

This water filtration unit has a good-looking stainless-steel finish and carbon plus filtration cartridges that can go as long as 2-years without needing replacement.

Chlorine Water Filters Buyers Guide

Why Is Chlorine Added to Our Tap Water?

Chlorine is very popular tor use to treat tap water. So much so that the Environmental Protection Agency (EPA) and CDC estimate that over 60% of the households in the USA have drinking water that has been treated with chlorine.

When chlorine is added to municipal water to sanitize it, this is called Chlorination. It’s very effective at killing such microorganisms as bacteria, viruses, and parasites.

Among the waterborne pathogens that chlorinated drinking water is credited with largely keeping in check are those that cause E coli, typhoid, salmonella, dysentery, cholera, norovirus, and Legionnaires’ disease.

Is Chlorine in Drinking Water Dangerous?

My familiarity with chlorine tells me it’s a substance I would never willingly take into my body even in small amounts over a long time. Unfortunately, that’s what millions of Americans across the country do regularly.

If you have chlorinated water coming into your home and you or your family drink that water without it being treated further, then you expose yourself to many potential health problems.

This includes such minor problems as nausea, headaches, digestive tract issues, watery eyes, and nasal discomfort.

Longer-term effects of ingesting higher than recommended levels of chlorine can produce such severe consequences as pulmonary edema (fluid buildup in the lungs) and lead to bladder, liver, colon, and other cancers.         

How Much Chlorine Is Typically in Our Water?

When looking for an answer as to how much chlorine is typically in our water, that’s very hard to say. Because different water sources have different chlorine levels. If you are on well water the answer may even be none at all.

If you are on city water, then there is a very good chance that you have water coming into your home that has been chlorinated before it gets to you.     

Testing your water for its chlorine level is the only sure way to know how much chlorine is in your drinking water.     

How to Test for Chlorine in Water?

You have many options when it comes to testing for chlorine. That includes everything from tests that just detect the presence of chlorine in your water to others that will test for chlorine and a wide range of other impurities that may be in your drinking water.

Here are the three main ways to test chlorine at home:

  1. Chlorine Only Test Strips
Test Assured Chlorine Test Strips

These are easy-to-use test strips that just measure chlorine levels.

  1. Chlorine Plus Test Strips
test-strips

These are test strips that will detect the presence of chlorine and several other water contaminants.

  1. Professional Lab Testing

You can order a professional lab testing kit online and when the water sample containers arrive, you just fill them up and send them back in. If I am going to take the time to do water testing this is the way to go for me.

That’s because these chlorine test kits will detect the presence of chlorine along with many other harmful impurities that may be lurking in your tap water.

tap-score

One professional lab test kit that I have had great results when using is the Tap Score Kits.

Which Types of Water Filters Remove Chlorine?

chlorine

By far the best way to remove chlorine from water is by using a filter cartridge or filter media that contains activated carbon. That’s because chlorine is very hard to filter out of water because of how easily it goes into solution.

Even membranes as small as 1-micron in size reverse osmosis filters don’t do a good job at filtering out chlorine. Carbon filters work because it has a substantial amount of surface area and it absorbs chlorine in water as opposed to trying to filter it out.

You will notice that every one of the best filters for chlorine in the chart above includes carbon filters or granulated carbon media. Carbon filters are also nice because they will usually go 6-months or more before needing filter replacement. 

Many people believe that boiling water remove chlorine is possible but that’s simply not the case. So it really takes a good water filtration system to remove chlorine and harmful contaminants from drinking water. 

Don’t Take Chances with Too Much Chlorine Consumption

After what you have read here, you are now well aware of the impact that chlorine in drinking water can have on you and your family’s health. It’s especially important to take steps to remove chlorine if you are supplied by municipal water that’s sanitized by it.         

So be proactive when it comes to removing chlorine from your drinking water and strongly consider adding a top-of-line whole house chlorine filter such as our #1 choice the Springwell CF1 Whole House Chlorine Filter.

At the very least, think about purchasing a simple point-of-use chlorine filter like the highly-rated Clearly Filtered Water Pitcher to help protect your family from the potentially harmful effects of chlorine and other common water impurities.
