Best Shower Filters for Hard Water of 2022

A shower filter is an affordable way to protect your hair and skin from hard water.

Hard water in the shower can cause your skin and hair to become dry and scaly. This is due to the high content of minerals that react with the soap, causing scum. The scum will form a film on your body, leaving it dry.

People with eczema will feel the effects of hard water more significantly as dry skin will trigger a reaction. An excellent way to improve the water in your shower is by installing one of the best shower filters for hard water. These are inexpensive and effective at removing minerals from your shower water.

How to Choose the Best Shower Filter for Hard Water

Choosing the best shower filter for hard water isn’t as difficult as you might think.

First off, you need to decide on the size and type of filter that would suit you and your shower. If you want to filter out other contaminants, you should check the product you’re considering to ensure it removes specific impurities.


How effective the different variations of shower filters are depends on the media inside. Which one you should choose depends on whether you want to replace your current showerhead or simply want to add a filter.

Showerhead Filter

A showerhead filter comes with a fully functioning showerhead and a built-in filter. It can be bulkier than regular showerheads, because it needs more room to store a cartridge on the inside.

These are generally easy to install by connecting the hose to the shower fixtures. You shouldn’t need any tools and you can simply hand-tighten it.

When choosing this type, make sure you check the water flow rate. Some showerhead filters will have a significantly lower flow rate, which can be frustrating if you’re used to a steady stream. A flow rate of 2.2 to 2.5 GPM (gallons per minute) is the general standard.

In-Line Filter

These filters are installed between the current showerhead and main water pipe. They’re usually easy to screw on and don’t require tools. Most of these come with a roll of Teflon tape that you can use when installing.

In-line filters are popular because they can be used with an existing showerhead. However, you have to check their compatibility. Although most in-line filters are compatible with most showers such as rainfall, handheld and wall-mounted, there are some exceptions, such as swivel showerheads.


Shower filters won’t last forever, and that’s crucial to remember. Sooner or later, the cartridge will need to be replaced.

If you fail to replace it, it could be doing more harm than good. Leaving an old filter could cause contaminants, such as chemicals and sediments, to return to the water. If the filter is full, it won’t be able to hold any more impurities; this will result in impurities making their way back into your shower.

Before buying a filter, check its lifespan; this is usually shown in gallons, such as 10,000 gallons, or by months. Going by the gallon is more accurate since a large family will use 10,000 gallons faster than a single person.

What Will Be Filtered Out?

Individual shower filters will remove various contaminants, and their effectiveness will differ significantly. If your biggest trouble is hard water, you should look for a filter that specifically claims it can dissolve minerals and scale.

You might also have other issues such as bad odor or other contaminants such as chlorine and rust. Read the description carefully before deciding on a filter to make sure you get what you need.

This filter is compatible with most showerhead types and is easy to set up as you won’t need any specialized tools.

The Pros

Easy to Install

Installing a water filter can sometimes feel like a major task only a plumber can do. However, this shower filter goes right between your showerhead and pipe. Simply unscrew the head and install the filter.

15-Stage Filtration

The 15-stage filtration will ensure that no impurities make their way onto your body. It consists of four main stages, each containing specialized filter methods.

  1. Filter step one: In the initial stage, there are two stainless steel filters and a microporous cotton filter.
  2. Filter step two: Within the second stage, there are five different filters, including KDF-55, calcium sulfite, activated carbon, negative ion balls and medical stone.
  3. Filter step three: The third stage consists of various balls, such as ceramic and magnetic energy beads. These work effectively at removing bacteria and absorbing metals such as lead.
  4. Filter step four: As the water enters the fourth and final stage, it will run through alkaline balls, microporous cotton, and an ultra-fine stainless steel netting filter.
Compatible with Most Showerheads

Buying a showerhead filter can be tricky when you’re not sure if it will fit your shower. However, this filter is compatible with most types of showerheads, such as rainfall, overhead, and handheld.

Consistent Water Flow

To further help improve your skin and hair, the showerhead is enhanced with vitamins that help to reduce dryness. Installation is straightforward and doesn’t require professional help or tools.

What makes this a luxury item are the bonuses and gifts you’ll receive with your filter. The stylish box includes a rain showerhead, caps, and Teflon tape to make installation a breeze.

The Pros

Rich in Vitamins

After the water has been through the 15-stage filtration, it will go through a vitamin cartridge. This additional filter adds vitamin C and E to your water. Vitamin C helps your skin repair damaged skin cells, rejuvenating your skin (3). Vitamin E helps to reduce dry skin and improves nail conditions (4).

Rain Showerhead

Many homeowners favor a rain showerhead due to the powerful stream. With this filter, you’ll get the ultimate soft water experience. The high-quality showerhead has an excellent water flow.

If you don’t want to use the included showerhead, you can easily install the filter only. However, you’ll then miss out on the added vitamins.

Effective Filter

The 15-stage filter will remove a significant amount of impurities such as minerals, heavy metals, and chemicals.

Many customers reported positive changes within the first week of use — most noticing improvements in odor and in their skin.

Good for People with Skin Conditions

If you’re dealing with eczema or any other skin condition, you might be significantly affected by the hard water in your home. Because of the ceramic balls and added vitamins, this filter should help to reduce symptoms and improve your skin.

4. AquaBliss Universal Shower Multi Stage Filter

Best Chemical-Free Shower Filter for Hard Water

If you’re after something powerful, but still chemical-free, then this filter is one to consider. It uses zero chemicals to mask the poor water quality. Instead, it’s packed full with premium filter media which is dedicated to water filtration. Not even two 15 stage filters would be as powerful as this AquaBliss universal multi-stage filter.

If you have hard water, this is a must-have product. In only a week, you’ll notice huge differences within your skin and hair. Plus, it doesn’t bring along those weird odors that some other hard water filters have.

In only a couple of minutes, you can have this filter up and running. From then on, enjoy purified water, less itchy skin, softer hair, filtration on hot and cold water, as well as other great benefits.

The Pros

Removes the Nasties

This filter is the most powerful at purifying your water. It prevents scale buildup, reduces chlorine levels, cleans out dirt, bad odors and pesticides. Now, the water you’re washing in will be purified, healthier and much kinder on your skin and hair.

Reduces Itchy Skin

A common appraisal from customers is that this helps with itchy skin. If your hard water is causing irritation or flaring up eczema outbreaks, this can help. The purified water is much kinder on the skin. So now when you step out of your shower, you can forget about the slimy, itchy and gritty feeling on your skin.

High-Quality Design

This filter focuses on high-quality design, compared to other multi-stage filters which use low-quality filler materials and more stages. This product uses quality redox media, double strength calcium sulfite and coconut shell activated carbon. These ingredients come together to eliminate nasties every single time you shower.

The Cons

Plastic Design

Keep in mind that the filter is made of plastic, not stainless steel, despite the images. This makes it less durable, more difficult to clean and a little bit cheaper.

Restricts Water Flow

You won’t notice decreased water pressure at first, but after a month or so, it’s definitely noticeable. If you love high water pressure, this may not be the best addition to your shower.

Flow Rate Not specified
Filter Lifespan 10,000-12,000 gallons

5. PureAction Water Softener Showerhead

Best Two-Stage Shower Filter for Hard Water

If you’re looking for a showerhead with a built-in filter, this is it. This showerhead consists of a two-stage filter cartridge, removing fluoride and chlorine and softening hard water.

You install it by removing your old showerhead and replacing it with this one. You’ll get an excellent flow rate of 2 gallons per minute and a three-setting showerhead for the ultimate shower experience.

PureAction has included two replacement cartridges in the package. This enables you to save a few extra bucks when it’s time to change the filter.

The Pros


The showerhead is fitted with micro-nozzle technology that provides high pressure, without wasting water. This could be the perfect addition to an eco-friendly household who’d like soft shower water.

Softens Water

Even though the cartridge is only two-staged, it’s still powerful and will remove up to 99.9 percent of impurities. Contaminants such as rust, heavy metals, fluoride chlorine, and sediments will be gone from your shower.

You might start to notice differences in your nails, hair, and skin since the softer water reduces dryness.

Three Showerhead Settings

One of the main reasons why we like this filter is the versatile showerhead. You get three different settings to choose between to create the perfect bath for you.

The settings include rain, power rain, and massage. Each set has a high pressure that won’t disappoint.


If you’re not entirely sure whether or not to purchase a filter like this, maybe the warranty will ease your mind. PureAction provides you with a one-year warranty that covers the showerhead and filters.

The Cons

Plastic Construction

Although the filter is effective and you get three settings to choose from, the construction might seem a bit flimsy. It’s mostly made out of plastic, which was a bother for some customers.

6. Vitafresh Shower Filter by UBS

Best Vitamin C Shower Filter for Hard Water

Koreans are well-known for their lustrous glass skin. Their beauty regimen starts from shower time before they continue with the skincare routine.

This Korean-made unique showerhead effectively neutralizes chlorine and chloramines from the hard water.

Its filter consists of DOLKI ceramic ball that helps break water molecules to make it smaller thus revitalizing your body.

Using food-grade Vitamin C, you can be sure of its efficiency and eco-friendliness. The cartridge can filter up to 10,000 liters of water and is recommended for replacement every two months. Worry not because its Vitamin C cartridge is affordable and comes in a pack of 5.

The Pros

Enhanced with Vitamin C

Vitamin C is essential to our health and body — it’s a powerful antioxidant that aids in our skin’s regeneration process (5). The vitamin C cartridge helps to balance the skin’s pH-level by adding natural acids to the alkaline hard water (6).

Easy Installation

The showerhead filter connects easily to any standard shower arm.

Total Chlorine Neutralization

Householders often complain about unpleasant chlorine odors coming from their water. Vitafresh has, therefore, made use of pharmaceutically food-grade ascorbic acid to neutralize chlorine effectively.

The Cons

The Cartridge Doesn’t Last Long

Vitamin C cartridge requires replacement every two months. If you’re a small family, it might make it to four months.

Additional Specs

7. Culligan WSH-C125 Wall-Mounted Shower Filter

Best Showerhead Filter for Hard Water

This shower filter is a bit different from the others we’ve reviewed. It looks identical to a regular showerhead, and you might not even think it’s a filter upon first sight.

Compared to other showerhead filters, this model isn’t all plastic. It’s durable and comes with a chrome finish that suits most bathrooms. The filter is a cartridge inside the showerhead and will provide up to 10,000 gallons of pure water before it needs a replacement.

Installation is super simple, and you get five spray settings to choose from. The filter will reduce chlorine levels and scale buildup. It will also help to eliminate bad odors coming from the water caused by sulfur or chlorine.

The Pros

Quick Installation

You get a roll of Teflon tape with the filter for quick installation. Simply remove the old showerhead and attach this. There are no tools needed; all you have to do is hand-tighten the filter.

Certified Filter

The showerhead filter is independently tested and certified by the NSF. This means it’s made of safe materials that won’t alter the water, and it removes impurities effectively.

Five Spray Settings

Many homeowners refrain from buying showerhead filters due to the fear of low water pressure. However, the Culligan showerhead allows you to choose between five settings — these include a full-body spray and a powerful pulse.

The showerhead will further provide you with a flow rate of 2.5 GPM. This is the standard rate for showerheads.

The Cons

Difficult to Distinguish Between Settings

Although customers are very pleased with the optional spray modes, some found it tricky to identify them. To change between the settings, you have to turn a knob on the showerhead.

We feel that, in our experience, such settings take a bit of time to get used to.

How Hard Water Affects Your Showering Experience

Hard water has a high content of dissolved minerals such as calcium, magnesium, and iron. How hard your water is depends on how high the mineral content is (7).

Signs that you have hard water could be water stains or white marks on dishes and other surfaces. These are dried mineral deposits that are left behind after hard water droplets evaporate.

Hard water can also affect your skin and hair, causing dryness. As you shower in hard water, the minerals will react with soap and shampoo and cause scum. Soap scum can build up on your skin, hair, and bath, forming a residue.

Soap and shampoo also have a harder time lathering in hard water, reducing the effectiveness of soap, due to calcium carbonate (8).

You can install a water softening system in your home to remove hard water. The most common system is ion exchange, which replaces hardness ions with salt ions (9). However, this does increase the sodium content of your water, and it isn’t recommended to drink daily, especially if you’re suffering from cardiovascular issues (10).

Take Note

A shower filter is the best option if you want to soften the water in your shower only. This allows you to get all of the health benefits of drinking hard water while improving your hair and skin.

How the Media Work

The media inside the filters are what removes or reduces impurities. Most shower filters use multiple stages that are made up of several media — these range from two- to 15-stage.

Here’s a quick look at the most common media you can find in shower filters:

1. Vitamin C Filter

Some multi-stage filters include a vitamin C cartridge. These are primarily used to remove chlorine, with some having a removal rate of 99 percent. Vitamin C filters will also remove contaminants, such as chloramines and sediments (11).

2. KDF (Kinetic Degradation Fluxion) Filter

KDF filters are generally used along with activated carbon blocks to help extend the life of the carbon. It does this by protecting the carbon block from bacterial growth.

This media uses a combination of zinc and copper to create an electro-chemical reaction. The reaction causes electrons to be transferred between molecules, creating new elements (12).

In this way, a KDF medium can turn harmful contaminants into harmless components. Heavy metals such as lead and copper, will plate-out onto the media’s surface and will, therefore, be removed from the water.

3. Multi-Stage Carbon Filter

This filter consists of multiple stages that the water has to pass through. It usually starts with a tightly woven cotton filter or stainless steel netting. Because the cotton is so tightly woven, no particles larger than 0.1 to 0.3 microns can pass through (13).

The initial stage usually removes impurities such as debris, rust, sand, and sediments — it can also remove large viruses and bacteria.

If you choose a translucent filter, you might notice that it’s full of beads or balls. These are ceramic beads that help to exchange ions — they also block calcium and magnesium from passing through (14).

At last, the water will pass an activated carbon medium that will remove chemicals. These can be chlorine, chloramine, and even volatile organic compounds. Some multi-stage filters will have additional cotton or stainless steel media before the water exits the block.

Final Notes

A shower filter can be an essential item if you’re living in an area with very hard water. It will remove and reduce a significant amount of impurities, giving new life to your hair and skin.

When searching for the best shower filter for hard water, consider which type would suit you. A showerhead filter is easy to install, but an in-line filter is more subtle and won’t be as noticeable. Once you’ve taken into account the buying features we described above, you should be able to narrow down your shortlist.
