What is the purpose of a bathtub water filter?

Bathing with hard water can result in dry skin, brittle hair, and other problems.

Showering or bathing in chlorinated water accounts for around 60% of the chlorine that most individuals ingest daily.

However, chlorine is harmful to your hair and skin. Bath water also contains heavy metals and VOCs (volitive organic compounds).

Filtering the water can help eliminate these dangerous minerals from your bathwater, and the results will be visible immediately.

The advantages of water filters

Water filters provide numerous advantages, most related to your health. The following are some primary advantages of owning and installing a water filter in your home.

Chlorinated water is filtered.

The presence of chlorine and trace quantities of lead in local tap water is the most harmful component. Again, this isn’t a major cause for concern in small amounts, but it can cause health concerns over time, especially if you’re exposed to this type of water for an extended period.

Filters remove various pollutants, but most critically, they eliminate chlorine and lead, which can be particularly dangerous to pregnant women.

Bacterial filtering

Yes, trace levels of bacteria are present in local tap water, and filters can help keep them out of your bathing and drinking water.

This is not restricted to bacteria; viruses have also been reported to spread through the water supply. In addition, filters help to keep bacteria and other potentially hazardous chemicals from reaching you.

Hard water is removed.

Hard water is water that is high in mineral content. While this is generally safe for your body, hard water can leave calcium carbonate deposits in your bathroom, causing it to deteriorate.

Filtration aids in the removal of hard water and the cleanliness of your bathroom.

Assists with dry skin

Tap water typically contains significant levels of minerals, which can rapidly dry up your skin if exposed to it.

Filtered water removes any pollutants in the water, preventing your skin from drying out or becoming more irritated due to shower water exposure.

Aids in the relief of lung and sinus discomfort

Tap water contains traces of chlorine and lead, which can be extremely damaging to your lungs and sinuses if exposed for an extended time.

Long-term exposure to purified water will ease any lung or nasal irritation caused by filtering your water.

It can help you save money.

Filters can easily save you money in the long term by keeping your bathroom clean and your household in excellent health.

Although changing filters may appear costly initially, your bathroom and pipes will not have to deal with hard water deposits and other toxic compounds in the long run.

How do bathtub water filters function?

Each works differently, but water will generally pass through the filter. In addition, the inside has filtration features that will eliminate hazardous minerals, and the water will get cleaner as it passes through the fixture.

There are two general methods for filtering water with filters: physical filtration and chemical filtration. Physical filtering works in the same way that a strainer or colander does in the kitchen. As the water moves through the filter, a physical barrier removes and gathers larger particles, allowing the water to pass through without these elements.

On the other hand, chemical filtration employs basic chemical reactions from other materials to eliminate tiny contaminants that physical filters cannot capture.

  • The filter filters the water.
  • Physical filtration is used to gather bigger substances.
  • The residual impurities are trapped by activated carbon filters, with the carbon acting as a magnet for chemicals such as lead and other toxins.
  • Finally, chemicals such as chlorine are reduced when water comes into contact with activated carbon.
  • The water you get on the other end is safe to drink.

How to select the best bathtub water filter

When shopping for a bathtub water filter, consider some of the following features. Of course, not every bathtub filter will meet your requirements, so let’s look at the features of some of the best bathtub water filters and what they signify for your decision.


Do you require a multi-purpose filter? Or a filter specifically built for bathtubs? Or is a shower filter suffice for you?

These are some of the most typical questions people have when purchasing a bathtub water filter, as these factors significantly impact their purchasing decision.

Conditions treated

Hard water can have various negative impacts on your skin and hair, which a water filter can assist in curing. If you want to treat brittle hair or inflamed skin?

If you suffer from inflamed eyes, filtered water can assist. These parameters may vary depending on the filter you select.


What do you hope to get out of your water filter? Is it primarily chlorine? Or do you wish to get rid of the potentially dangerous minerals? Or do you require a filter that aids in adding minerals to the water?

Each of these filters works uniquely. As a result, it is critical to determine which filter is best suited to your objectives.

Positive Outcomes

Some filters add beneficial components to the water while eliminating harmful ones. This will boost the performance of your bathwater and allow you to see effects more rapidly.


This may be less significant to some, but some filters are available in various colors. Therefore, if you want the filter to blend in with your setup, you should think about the filter’s color.

Hard water in your home

You may be aware that hard water can shorten the lifespan of your equipment due to the dangerous mineral buildup. However, consider what that same water can do to your skin if you drink or bathe.

If you have sensitive skin, the source of the problem could be your water. It could also be your water if your hair is brittle and weak.

There are numerous methods for dealing with hard water in your home.

A whole household water filtration system is available, although they are rather pricey.

If you don’t want to invest in a full-fledged home water filtering system, you might want to explore a focused filter.

This could be for drinking water, appliances, or the bathroom. For example, you can filter the water in your sink, bathtub, or shower.

There are several types to pick from, but in the end, these filters will connect directly to your bathwater supply – whether directly or indirectly – and filter dangerous minerals from the water before usage.

You’ll notice a change immediately, and your hair, skin, and nails will thank you when you give them the same filtered treatment for the rest of your life.

There are further advantages, such as less scaling, which makes cleaning your bathtub easier. But, of course, that’s just a bonus since you’ll naturally want to focus on the health benefits!

Is hard water safe to bathe in?

Hard water is not as excellent for bathing as soft water, but regrettably, most homes have hard water. This is because hard water has a lot of calcium and magnesium ions, whereas soft water has fewer minerals.

The calcium and magnesium ions in hard water react with the soap, generating an insoluble combination known as soap scum, which inhibits a clean lather from forming.

You’ll need more soap to clean, and the residual soap scum will leave a dirty white smear around the bathtub.

Bath salts are a temporary treatment for softening rough bath water. The sodium and potassium ions from the salt replace the calcium and magnesium ions in the water, allowing the soap to lather much more easily. Furthermore, salt and essential oils will continue to benefit your skin.

If you want to enjoy the benefits of soft water throughout your home in the long run, consider installing a whole-house water softener.

Why is it better to bathe in soft water?

Bathing in soft water can be a calming experience for most people. However, a long soak in a warm tub can be the perfect way to unwind after a hard day, relax your muscles after a strenuous workout, or warm up your body after being outside in the cold.

While essential oils, bath salts, or bath gels are commonly used to soften skin, something may stop these products from bubbling and doing their work — your hard water!

You are not alone if you find yourself pouring more bath soap into your tub to achieve the desired amount of bubbles. Because hard water is found in 85 percent of Canadian homes, the likelihood that you live with it is high.

Hard water might not only increase your water bill, but it can also contribute to dry skin, brittle hair, and clogged pores.

Calcium and magnesium in hard water react poorly with the components in your products, such as bath gels, resulting in fewer bubbles in your tub.

There are a few fast remedies you can try to restore your bubbles, but the problem will never be resolved unless you obtain a proper water softener.

A water softener will produce more bubbles and keep your water soft throughout the day and night. Hard water can discolor your toilets, sinks, and water-using appliances and cause scale to build up in your plumbing and pipes.

This reduces the performance of your home’s water.

How can you lessen the hardness of bath water?

So, if you have dry skin, dull hair, and annoyingly low shower pressure, you are suffering from the impacts of hard water in your home. Don’t be concerned; you’re not alone.

Here are some of the most common quick-fix methods.

Bath salts

Do you want to know how to soften hard water naturally? As mentioned, bath salts not only scent the water but also soften it by releasing sodium and potassium ions, which replace the calcium and magnesium that create water hardness.

Baking Soda

While adding baking soda to your bath water will not chemically soften it, it will make it feel slicker and soften your skin. To try this procedure, mix 12 cups of baking soda into a tub of water and soak for around 15 minutes.

Install a bathtub filter

Some bath filters claim to soften your skin and hair by eliminating chlorine from the water. While this may mitigate some of the drying effects of chlorine, keep in mind that faucet filters cannot fully soften bath water.

The abovementioned ways may help your skin and hair feel less dry. However, keep in mind that these are temporary solutions. For example, do you want to have to add bath salts or baking soda to every bath to avoid hard water? 

If the answer is “no,” and you’re seeking a long-term solution that will soften your water throughout your home while potentially increasing your water pressure.

What about pollutants? What are some alternative ways to filter out pollutants in bath water?

The following are the most typical ways we reduce the pollutants in bath water:

1. C vitamin

Vitamin C is beneficial to the immune system, but it can also help to reduce the toxins in bath water. Chlorine is used in most municipal water sources to help minimize the number of pathogens in the water.

Unfortunately, the cure is not often as effective as the sickness.

When chlorine is used to treat water, it reacts with organic matter to generate trihalomethanes (THMs), commonly known as disinfection byproducts. Chloroform, a recognized carcinogen, is one of the most prevalent THMs.

Other THMs created include di- and trichloramine, produced when chloramine is employed as a disinfectant. When these chemicals are ingested, inhaled, or applied to the skin, they are poisonous.

Although carbon block filters (such as those used for drinking water) will remove chlorine, they can be difficult to utilize for shower/bath water. Another straightforward alternative is to use Vitamin C to counteract the chlorine in bath water.

Vitamin C will also neutralize Chloramine (chlorine and ammonia), commonly used in water treatment and potentially more hazardous than Chlorine.

Two types of Vitamin C will act more effectively to neutralize chlorine:

  • Vitamin C in the form of ascorbic acid
  • Vitamin C in the form of sodium ascorbate

You can find them here if you’re curious about chemical reactions and byproducts. I prefer Sodium Ascorbate because it has less impact on the pH, but either form would suffice.

A teaspoon of each of the Vitamin C forms should be enough to neutralize a tub of water, and it is best to leave the powder in for 2-5 minutes before getting in the bath to enable it to work.

If you don’t like having to add the powder to your bath every time, there is a bath ball de-chlorinator that can do the same thing and is good for almost 200 baths!

2. Clay

Healing clays, such as Bentonite Clay, bind to heavy metals in the body and aid in their removal. This same activity can occur externally, and clay is frequently used in baths for detoxification.

Because of its propensity to develop an “electrical charge” when hydrated, Bentonite Clay is a one-of-a-kind clay. When it comes into touch with fluid, its electrical components alter, allowing it to absorb pollutants.

As a result, toxins, heavy metals, pollutants, and chemicals can all be absorbed and removed by bentonite.

Bentonite is a clay that expands. When it comes into contact with water, it swells open like a porous sponge. Toxins are attracted to the sponge by electrical attraction from here, where they are bound.

I use Bentonite Clay to purify my hair and as a sort of “shampoo,” but I also often add bentonite clay to my children’s baths after removing the chlorine.


When working with Bentonite, avoid using metal because it reduces its effectiveness. Instead, combine 2 teaspoons of Bentonite Clay with water in a glass container with a plastic cover and shake vigorously.

After the chlorine has been eliminated, I pour this into the bath. I’ve personally used and had good results with two types of clay:

3. Minerals and salts

I’ve written (a lot) on magnesium before (are you sick of hearing about it yet?). Unfortunately, many of us do not obtain enough magnesium because of decreased soil magnesium levels and the usage of synthetic fertilizers.

Adding these minerals to children’s bath water is one of the simplest ways to help them prevent this problem. This is an excerpt from an article about Epsom Salt:

According to research, magnesium and sulfate are both easily absorbed via the skin, making Epsom salt baths a convenient and excellent approach to reap great health advantages.

Magnesium has several functions in the body, including controlling the action of over 325 enzymes, lowering inflammation, assisting muscle and nerve function, and preventing arterial hardening. Sulfates aid in the absorption of nutrients, the removal of pollutants, and the relief of migraine headaches.

Difference between a water softener and a water filter

There is no guarantee that homeowners will not encounter some difficulties.

There are several ways your water supply might be impacted, whether a hard water issue with limescale or outdated pipes poisoning your drinking water.

Some you may not even be aware of…

A water softener or filtration system can provide homeowners peace of mind, but what exactly do they perform?

How does a water filter work?

Water filters can treat contaminants and remove impurities such as lead and pesticides from your drinking water using various water purification procedures.

Activated carbon, reverse osmosis, and sediment filtering is the most often used ways of eliminating contaminants.

The water filter system is often installed beneath the kitchen sink and cleanses the water that flows from the kitchen faucet.

Contaminants are captured and eliminated by system cleansing or contained in a cartridge membrane that must be replaced after a set amount of time, depending on the type of filter.

Households that want the greatest drinking water should install a water filter system to eliminate impurities such as bacteria, pesticides, lead, and chlorine from their water supply. This ensures that your drinking water is safe for the entire family to ingest.

How do water softeners work?

Water softeners work by removing calcium and magnesium from the water through a process known as ion exchange. The hard water runs through a bed of spherical resin beads as it enters the mineral tank.

These sodium-ion-charged plastic beads are typically constructed of polystyrene.

The resin beads are anions, which means they are negatively charged. On the other hand, calcium and magnesium are cations because they have a positive charge.

Because opposing charges attract, the minerals’ negative charge is drawn to the resin beads’ positive charge.

As a result, the beads take hold of the mineral ions and remove them from the water as the hard water travels through the resin. The sodium ion is released when the bead seizes the mineral ion.

As the water goes through the mineral tank, the resin column removes all of the hardness, and softened water flows into your home.

Selecting a system for your home

Whether you buy a water softener or a filtration system is determined by the troubles you’re experiencing.

A water softener is an ideal remedy if the impacts of limescale plague your property.

This keeps your bathroom and kitchen clear of hairy, chalky buildups, allowing your boiler and appliances to operate normally and effectively without the risk of major and costly problems.

A water filter is recommended if chlorine impacts your water’s smell and taste or if you are concerned about toxins such as lead and pesticides affecting your family.

This ensures that the water you’re drinking is of great quality and safe to consume for the entire family.

Wherever practical, we would recommend a whole home solution, which combines a softener and a water filter to offer soft water throughout your home and pure, filtered drinking water right from the tap.


Most people only consider water filters for drinking water, and they are unaware that using hard water might have detrimental impacts on their health.

Now that we’ve looked at some of the finest bathtub filters and features, let’s look at some of the most frequently asked questions to help you choose the best water filter.

Is it possible to install a water filter in a bathtub?

For smoother skin, the bathtub filter securely removes chlorine, hypochlorous acid, filth & smells, and sediment from your bath water. It takes only a few minutes to install and is ready to use immediately.

What contaminants can bathtub water filters remove from water?

Water filters can remove chlorine, fluoride, bacteria, viruses, pollutants, and pesticides while adjusting the pH of the water.

What benefits may a filter bring to your water?

Some filters also incorporate healthy minerals to help renew your water, such as magnesium and zinc. Instead of only minimizing negative outcomes, this will help to provide even more favorable outcomes.

What are the advantages of utilizing a bathtub water filter?

Your skin will be less dry, your hair will look healthier, your eyes will be less irritated, and so on. These are only a few advantages of using a bathtub water filter. Just because you aren’t drinking it doesn’t mean you shouldn’t filter it!

Do I need to bathe babies and children in filtered water?

It is all up to you. The same advantages that adults enjoy will be extended to babies. Unfiltered water can cause skin irritation.

What is the lifespan of bathtub water filters?

Bathtub filters typically last between 3-6 months, depending on usage. However, because each instance will differ substantially based on the individual, it is better to verify the package or consult the manufacturer for a more accurate time frame. In addition, it is best to change your filter as soon as possible if it malfunctions.

Can I change the filters?

Each unit is unique. Some include replaceable filters, while others require purchasing an entirely new device. Therefore, examine each product thoroughly to ensure that you understand the requirements.

Is it easy to install the bathtub water filters?

Again, each device is unique; nevertheless, most of the water filters on this list are simple to install. They either slip over the faucet, filter running water, or clip on quickly.


While a bathtub water filter may appear a luxury to some, it is affordable. Investing in one of these filters makes perfect sense, given the men’s skin, hair, and overall health benefits.

The CuZn Bath Ball Faucet Filter, which we rated above as our top overall option, is the greatest bathtub filter we can locate. The pricing is not prohibitively expensive, and the reviews are generally favorable. So, if you’re looking for a tub filter, this is the one we recommend.
