What to Look For in a Shower Head Filter


These are the most critical specifications that you’ll want to compare when considering different shower head filters, and they’re the main criteria we used to evaluate our choices for the best shower filter.

Contaminants Removed

Not all filters are created equal, and not all products are going to work on the same number and classes of contaminants. The types of filtration media that each shower head filter uses are ultimately going to determine the contaminants they work on, and every brand uses its own unique blend of media.

Do you struggle with a high chlorine content from your municipal water supply, or do you have higher levels of heavy metals like iron?

You can find out by getting your water tested with a water test kit, and once you have the breakdown of the main contaminants in your water you’ll be able to tailor your filter selection to your home’s needs.

Filter Lifespan & Replacement

The filter lifespan will tell you how much maintenance you can expect as well as how much ongoing cost there will be for the replacement filters. The lifespan of a shower head filter can either be described in months or gallons of water used.

You’ll also want to look at how easy the filters are to replace. Will you need a wrench, pipe cutter, and an hour of your time, or five minutes and some elbow grease? You’ll want to make sure you’re not signing up for extra hassle with a filter that’s difficult to replace each time.

Flow Rate

If you’ve ever had to take a shower with pitiful water pressure, you know how frustrating it can be to try to rinse off soap and shampoo with minimal flow. Flow rate is one of the biggest determinants of customer satisfaction with a product, so you’ll want to check how much of a hit your water pressure is going to take beforehand.


The material a showerhead filter is made from will determine both its aesthetics and its durability. Plastic may be more prone to cracking than metal, but anything other than stainless steel will have the potential to rust. Some filters also come in different styles and finishes so that you can choose the one that best matches the other fixtures in your bathroom.


Getting independently tested and certified by either the National Sanitation Foundation (NSF) or the Water Quality Association (WQA) is one way that filter manufacturers can prove that their products live up to their claims. It’s an added assurance for the consumer, and there are multiple different quality standards that water systems can be certified for.


With all of our contenders below, no matter where they fall in the price range we made sure that they offer the most value possible for their price. When looking at the price of a shower head filter, you also have to consider both the initial price and the ongoing costs of the replacement filters.

Shower Filter Buyer’s Guide


Now that you know the top models on the market, these are the other details and tidbits that can help you make the best decision on a shower filter for your home’s needs. 

What Is a Shower Head Water Filter?

Shower head filters are considered point-of-use systems, which means that water is filtered only at a single exit point – your shower – rather than through the whole house. 

There are two main types of shower head filters: those that are incorporated into the showerhead, and those that are separate.

Incorporated Filters 

Incorporated shower filters are built into the body of the shower head so that it’s all a single part. 

These filters are also referred to as inline shower filters where they screw in with the existing shower head.

Some manufacturers will only add filters to a single showerhead type, while others will give you the option to choose between multiple different styles including shower wands. 

There are also some models, like the Berkey Shower Filter, where the filter isn’t built into the actual showerhead but it still comes as a single unit.

Stand-Alone Filters

Unlike incorporated shower filters, these products don’t come pre-attached to a showerhead. 

Instead, they are usually equipped with ½ inch fittings that make them able to fit into almost any existing shower head setup. You would simply install the filter prior to installing the showerhead. These can be fairly streamlined or they can be rather bulky depending on the manufacturer.

How Do Shower Filters Work?

Shower filters are made to remove the contaminants that are going to have the biggest effect on your skin and hair – which is namely chlorine and harness-causing minerals. 

The exact contaminants a showerhead filter removes are going to depend on the filter it uses, and below are the most common filtration media used in these products.

Oxidation-Reduction Media

This media is usually found in the form of kdf filters or copper-zinc granules. It works by either oxidizing (taking an electron from) or reducing (adding an electron to) the different ions that come across it in the water. This makes it especially good at removing heavy metals like lead and mercury.

Activated Carbon Filters

A staple in the water filtration industry, activated carbon is made from a carbon source that has been heated to extremely high temperatures and treated chemically with argon and nitrogen. 

This causes the carbon particles to become extremely porous and have massive surface areas to bind contaminants with, and they also have the ability to electrostatically trap contaminants.

Activated carbon is great for removing chlorine and other impurities that cause foul odor, and it works best on organic contaminants like herbicides, pesticides, volatile organic chemicals, and some pharmaceuticals.


This is a catch-all term for anything that filters by making holes that the contaminants are too large to pass through. 

In this regard, activated carbon can be considered a form of microfiltration. You can have a very wide range of pore sizes – from 5 microns down to 0.05 microns – so the exact contaminants removed will depend on how fine the filtration media is.

Vitamin C Shower Filter

Vitamin C shower filters are mainly included in the filtration media of shower water filter system because they are very effective in removing chlorine and chloramine as well as other sediments.

The best vitamin c shower filters can remove up to 90% of chlorine so if chlorine is a contaminant you’re dealing with take a look at shower head units with a vitamin c filter.


Another catch-all term, this just means that the manufacturer has come up with their own blend of filtration media that may work via several different mechanisms – and they’re not sharing the trade secrets.

What Are the Negative Effects of Showering in Unfiltered Tap Water?

Unless you’re drinking your shower water, you shouldn’t have nearly the risk of negative health effects with unfiltered water in your shower as you would for drinking. 

Having said that, there are still multiple negative effects associated with showering in unfiltered water, and each contaminant culprit is broken down into more detail below.


Chlorine is a commonly added disinfectant in municipal water supplies. It exists in two main forms in water: free chlorine, and chloramines. Free chlorine is what it sounds like – unbound chlorine atoms that generally ionize into chloride.

Chloramines, on the other hand, are what is formed when chlorine forms chemical bonds with other elements and molecules. Due to its structure, chloramines are much harder to remove from water than regular chlorine.

Chlorine can cause skin irritation in high quantities but you’re highly unlikely to encounter chlorine at a level high enough in your shower water for that to happen. That means you’re good, right? 

Well…not quite.

It can strip your skin and hair of its beneficial oils, leaving your skin dry and your hair dry and brittle. 

Over time, it can also cause color-treated hair to turn various shades of green. The worst potential effect of chlorine is when it comes out of the water as vapor and gets inhaled. This can cause respiratory irritation and trigger asthma.

Hard Minerals

Like chlorine, hard water is also associated with skin irritation. 

Hard water is caused primarily by calcium and magnesium ions in the water, which precipitate out and accumulate as scale. Scale is drying to the skin and hair, and it can even clog pores to make acne and eczema flares more common. In your hair it can also contribute to dandruff and scalp irritation. This is because, like chlorine, hard water removes your natural oils.

Scale also prevents soap from lathering properly, so you’ll often find yourself using more soap, detergent, shampoo, etc than you would with soft water. As scale builds up on our fixtures and in your appliances, it can cause your water lines to become clogged and can shorten the lifespan of your water heated, dishwasher, etc.

Benefits of Using a Shower Filter

A shower filter will improve the health of your skin and hair, and your water will smell better and feel smoother as you shower. Below are the main benefits of installing a better shower head.

Softens Hard Water

Shower filters often soften water which will prevent the negative effects from calcium and magnesium minerals, and this will keep your showerhead from being clogged with scale as well.

Removes Chlorine

Removing chlorine will also benefit your skin and hair and remove the risk of inhaling the vapor, while making your water smell less like a swimming pool. 

Young kids are more susceptible than adults to the negative effects of chemicals like chlorine in water, and removing these chemicals will lower their risk of respiratory diseases like asthma.

Removes Other Contaminants

Chlorine isn’t the only chemical that makes water smell unpleasant, and many filters also work on the other culprits like zinc, hydrogen sulfide, herbicides, pesticides, and microorganisms. 

If you run on well water, your filter may still let some iron and hydrogen sulfide come through the system. A shower head filter would help prevent the orange staining and foul odors that might slip through.

Also, some shower filters work to prevent the growth of or even kill some microorganisms, which is definitely an added benefit. 

The damp environment created by residual water in the showerhead and filter can be a breeding ground for bacteria, mold, algae, etc, so getting a model that prevents that growth will help ensure your filter lives up to its potential. 

How to Choose a Shower Filter

Choosing the best shower head filter can feel like a tall order, especially with all of the different products on the market. 

You want a filter that will remove the main contaminants in your water (and is preferably certified to do so), won’t require a lot of maintenance, will maintain your water pressure, and won’t break the bank. 

Let’s look at each of those a little bit closer.

Contaminants Removed

As mentioned, having your water tested to see what contaminants are present is the best way to ensure you’re choosing a filter that will address your home’s specific needs. This will help you decide if you need a workhorse like the Propur Promax that removes an extremely large number of contaminants, or if you can go with a different filter that may have other benefits.

The main contaminants you’ll want to remove are the ones with potentially negative health effects like chlorine and hardness – if they’re present in your water. You can see our choices for the best water testing kits here.


Once you know what contaminants you need to get out of your water, you can look for a filter that’s certified to do so. Keep in mind that while certification is the gold standard for water filters, many choose to have their products tested through independent labs without paying to go through the certification process.

The tests are often performed with the same standards they would be certified for, so it’s a way that manufacturers can guarantee their products without having to pay extra for the certification.

Filter Lifespan and Replacement

We discussed the lifespan of filters being in months or gallons, but the two are not always created equal. The lifespan in months will vary from one household to another due to variations in usage, while the lifespan in gallons is the more universal measurement. For example, a family of four that showers twice a day will go through water much faster than a family of two that only showers daily.

Most shower filters have one of two methods for replacing their filters: they screw out, or they pop out. Both are very quick and simple to use fortunately, and you shouldn’t have much of a problem doing filter replacements. You’ll still want to check, though, in case you come across a filter that is going to be a hassle to replace.

Flow Rate

There’s a government regulation that states that new showerheads cannot have a flow rate over 2.5 GPM, so this is the maximum and the goal for shower filters. Most showerheads accomplish this with a restrictor placed somewhere in the model, though forcing water through a filter naturally wants to reduce its flow.

In order to keep from experiencing any of the headaches that come with low water pressure, you’ll want to get a shower filter with the maximum flow rate or close to it.


As mentioned, the price of a shower head filter is two-pronged: what you’ll pay now, and what you’ll pay down the road for replacement filters. A system with a high up-front price but long filter lifespans may save you money over time compared to a system that is less expensive up front but requires more maintenance.

Other Considerations When Buying a Shower Head Filter

Shower head filters come in many different styles and designs, and they’re often available as just the filter so you can use them with your own head. 

You’ll want to make sure the filter you choose matches up with the other fixtures in your bathroom. 

With the design, you’ll also want to make sure the filter isn’t going to lower the height of your showerhead beyond what is practical for you.

Don’t forget to look into a product’s warranty as you’re browsing as well. Some models like the Berkey will come with a lifetime warranty, while others will only last for months to years. This can give you an idea of the expected durability of the shower head filter as a whole, and nobody wants a system that’s going to break soon after purchase.

As with anything, customer reviews can also give you great insight into what day-to-day use looks like, and what the consistent problems are that customers seem to run into. 

How to Install a Shower Filter

The only tools you’re likely to need are teflon tape and a pair of pliers, but note that the pliers are for removing the old shower head only. 

Overtightening your new filter can lead to leaks, so you’ll usually just want to hand-tighten those.

Step 1: Remove The Old Shower Filter Head

Unscrew the head by rotating it counterclockwise, using the pliers if required.

Step 2: Place the New Showerhead

Once the old head is off, remove the cap on the filter outlet if applicable and apply teflon tape to the threads on the shower arm. You can then screw the filter onto the arm, making sure that any gaskets and washers in the filter are seated properly.

Most shower filters recommend that you do not use them with a shut-off valve, and if your shower arm does come with one they recommend installing the filter after the valve. This will prevent water pressure from accidentally building up in your filter and damaging it.

Step 3: Place/Replace the Showerhead

Once you get your filter in place, run some water through the filter to flush it for 10-20 seconds, then wrap teflon tape on the outlet of the filter. Screw the shower head back onto the filter, likewise making sure all gaskets are in their proper place.
