Shower Filter Reviews

If you’ve never thought about a shower filter, you probably don’t know where to start looking for the best shower filter, or what to look for. That’s where this guide comes in. We are going to show you some showerhead filter reviews of some of the most popular models. Then we’ll give you a buying guide that will walk you through how a shower filter works and what you should be looking for when you buy one.

# 1. The Winner

Aquasana water filter

  • Long Lasting & Cost Efficient Filtration
  • Maximum Filtration & Water Pressure
  • Premium NSF Certified Filtration Media

Our top pick is AQ-4100 Deluxe shower filter by Aquasana. This water shower filter is a little different than others you may have seen. It has a larger filter that hangs below the showerhead. The filter uses coconut shell sourced AquaSorb HX filtration to remove odors and begin chlorine removal. A separate KDF 55 copper/zinc blend further reduces chlorine and dissolved metals, balancing out the pH.

This kit is easily installed on any standard shower fixture with a 1/2 inch fitting. The filter is removable and replaceable. The optional showerhead has multiple massage settings as well. This is a good hard water filter for showers.

# 2. Runner Up

Berkey Filtering Massaging Showerhead

Berkey Filtering Massaging Showerhead

  • Reduces lime, scale, mold and fungi 

This all-white elegant showerhead installs easily in place of your existing showerhead with a standard 1/2-inch fitting. The showerhead has multiple massaging settings and self-cleans with a backflush attachment.

It uses a reduction-oxidation chemical reaction to reduce free chlorine in your shower water, turning it into a harmless chloride salt that rinses away. The reduction of chlorine means that your water will smell fresher and be less drying on your skin. The filter is replaceable; you can either replace the internal filters or the entire filtration housing if you prefer.

AquaBliss SF100 Inline Shower Filter

AquaBliss SF100 Inline Shower Filter

  • Ultra-Fine Stainless Steel Mesh
  • Micro-Porous PP Cotton traps 
  • Zeolite Ceramic beads
  • 1.01 pounds weight

This shower filter is designed to fit inline before your showerhead. It comes in a polished chrome finish and has a 1/2-inch fitting designed to fit all standard showerheads and potable water plumbing. It weighs just under a pound so it won’t add much weight to even your best rain showerhead at all. It measures just under 5 inches long and is about 3 inches in diameter. That makes it about the size of a fat soda can.

It filters your water through a 12 stage process that uses a combination of mechanical and chemical filtration. The mechanical filters are microporous cotton, an extra-fine mesh, and sand. The chemical filters are activated charcoal, calcium sulfite, and redox media. Redox stands for reduction-oxidation, a chemical reaction that reduces an impurity’s electron state to make it easier to remove.

This filter also claims to use far infrared media, zeolite, vitamin C, tourmaline, and a magnetic element to add revitalizing minerals and substances to your water to improve your skin and hair health.


  • Filter location: Bathroom inline before showerhead
  • Type of Filter: 12-stage chemical and physical filtration
  • Lifespan: 12,000 gallons
  • Dimensions: 4.7 x 3.3 x 3.3 inches

Barclay’s Buys Better Home Goods Filtering Showerhead

Barclay’s Buys Better Home Goods

  • High Pressure & Save Water
  • Toggle Switch Style
  • 2.5 Gallons Per Minute
  • 6 ounces weight

This is a filtering showerhead meant to replace your existing showerhead. The replaceable filter inside gives you clean and filtered water without requiring you to install a separate filter. It installs on any standard shower neck with a 1/2-inch fitting. The internal cartridge is easy to replace and lasts about six months according to the manufacturer.

The filtration mechanism inside the cartridge uses a filter sponge as its physical filter, removing sediment. It also has calcium sulfite stones and an ion box that are both designed to remove chlorine and other dissolved minerals in your water. The filter easily disassembles if you want to physically clean the filtration sponge as well.


  • Filter location: Showerhead replacement
  • Type of Filter: Replaceable chemical and physical filtration cartridge
  • Lifespan: 6 to 8 months
  • Dimensions: 4” (Length) x 3” diameter showerhead
  • Weight: 6.1 ounces

Culligan WSH-C125 Filtered Showerhead

Culligan WSH-C125 Filtered Showerhead

  • 10,000 Gallon
  • 140 filter cartridge
  • 40°F-120°F temperature range
  • 1.8 gallons per minute 

This filtering showerhead replaces your existing showerhead, giving you filtered shower water without the need to install a separate in-line water filter. This showerhead has a 1/2-inch fitting, so it will install on any standard shower neck. The showerhead is a little larger than your average low-flow showerhead, but that’s so it can accommodate the replaceable WHR-140 cartridge inside.

The cartridge uses both physical and chemical filtration to remove odors and help soften the water. While the filter is rated for 10,000 gallons, if you have exceptionally hard water, it might not last that long. Harder water can wear out the salt softening filter sooner. The showerhead has five spray settings and is easily installed by using the included Teflon tape and screwing the head onto your shower pipe.

This filtrating showerhead is independently certified to reduce the chlorine levels in your shower water, so you don't have to worry. So if you're looking for a water softener shower head, this is a great place to start.

# 6. High Output Universal Shower Filter

AquaBliss SF220 High Output Universal Shower Filter

AquaBliss SF220

  • Activated Carbon
  • Pre-Filter Washers
  • Replaceble Sediment Filter Pads
  • Free Compatibility Adapter

This high-quality inline shower filter installs on your shower neck before your showerhead. The fitting is a standard 1/2 inch designed to fit all standard shower heads and shower necks. The filter and cartridge have a total weight of 15.2 ounces, so it won't weigh down your handheld showerhead or a showerhead with high pressure.

The chemical filters include calcium sulfite for chlorine reduction, reduction-oxidation media to remove even more chlorine and to help prevent scale buildup, and activated charcoal to help remove odors.

The filter is easily changed out with the SF-100 or SF-220 cartridges whenever you notice they stop working. They have a tested lifespan of 10,000 to 12,000 gallons, but depending on the hardness and content of your potable water, you may experience different results.

  • Dimensions: 5.4 x 3.7 inch cylinder

Shower Filter Buying Guide

Best Shower Filter Reviews

Now that you have read the best shower water filter reviews, it’s time to talk about what to look for when you start shopping for your very own shower filter. First, let’s talk about how shower filters work.

What is a Shower Filter and How Does it Work?

A shower filter is essentially a water filter that is designed to fit in your shower line before your showerhead. Some filters are actually showerheads with filters built into them. As the water flows from your source (whether that's the city or well water) it goes through several filtering mechanisms. Some filtration is physical and some is chemical. There are general types of filtration for shower filters.

  • Physical Filtration – This method of filtration uses some sort of physical barrier to remove impurities from the water. These can be metal meshes or screens, fine-fibered cloths, or even cotton balls. These act to remove sediment and can also trap organisms as well. Other types of physical filtration actually use sand to clean impurities from water.
  • Chemical Filtration – chemical filtration uses the chemical properties of different materials to remove impurities from your water. For the purpose of filtering shower water, there are two methods that are primarily used. The methods of forced osmosis and steam distillation are not used because of the lack of pressure and the lack of available space to mount a steam kettle.
    • Ion Exchange – Primarily used to soften hard water, this chemical process releases sodium ions and exchanges them for heavy metal ions. This helps to reduce the harshness and metallic taste of water as well as reducing the number of hard water deposits that end up on various places. This has the added benefit of reducing scale as well as hard water stains.
    • Activated Carbon – This chemical filtration is designed to trap compounds like volatile organics which are the primary cause of bad smells. Activated carbon has a very large surface area so when you pass water over it there is a relatively large area for impurities to be trapped. Activated carbon or charcoal filters also can remove chlorine from the water as well.

Benefits of Having a Shower Filter

When you understand how water is filtered, it becomes easy to see what the benefits of having a shower filter really are. After all, why would you bathe in water that you wouldn't want to drink? Here are four of the largest benefits that are most often mentioned when talking about shower filters.

  • Reduces Chlorine-Free

Chlorine in water has many negative effects. Think about the last time that you have gone to a public pool. Public pool waters are heavily chlorinated to remove bacteria and keep the public waters clean. However, think of how the water makes your eyes sting, how it tends to burn the more delicate nasal passages, and how it dries out your hair and skin.

  • Stops Bacteria and Viruses

The various types of filtration also remove harmful pathogens from water. While most municipal water supplies are chemically treated to prevent the presence of bacteria and viruses, water main breaks or contamination of water supplies can happen. Additionally, if you rely on a well water source, your well can be contaminated by flooding, animals, or natural disasters.

Physical and chemical filtration of your shower water will prevent harmful pathogens from making their way to your skin and hair. And it will also prevent you from ingesting them.

  • Reduces Harmful Chemicals

Unfortunately, water pollution happens. Sometimes harmful chemicals are introduced to water to sanitize it. Chlorine is one such chemical that can easily bond with atoms to form compounds that you don't want in your water. Chemical filtration helps to neutralize free chlorine as well as remove other compounds that can dry out your skin, irritate your eyes, or damage your hair.

  • Softens Hard Water

Hard water is a pain. The excessive minerals in hard water leave scale in the form of white mineral deposits everywhere. You can even find them on your bathroom faucets. This scale is extremely hard to clean without resorting to other harsh chemicals. Inline water filters can help reduce the hardness by introducing sodium ions into your water which replace the heavier metallic ions. This gives your water a softer feel, which actually improves the effectiveness of your soap and shampoo, and removes the metallic taste from the water.

So you can see why you should get a water filter. The benefits of a water filter on your overall appearance and health can be worth more than the slight cost of a filtration device.

Things to Consider Before Buying a Shower Filter

So now that you know why you should buy a water filter it's time to look at the things that you should pay attention to when you're shopping for a water filter. There are really only five things that you should be paying attention to.

  • Types of Shower Filters

There are three types of shower filters. They are replacement showerheads, filters that are designed to be put in the waterline before your shower head, and those that combine the two.

Best Shower Filter Reviews

o Showerhead Filters - these are designed to replace the existing showerhead. These are a great idea if you have a standard shower head that doesn't have a lot of adjustments and you were looking to upgrade your shower head anyway. The filtration happens via a cartridge that is usually installed inside of the showerhead. These filters are usually designed to last about six months before requiring replacement. Depending on your needs and the type of showerhead that you want to change to, you can generally find something that will meet your needs.

o In-line Shower Filters - this type of shower filter installs in the water line before your shower head. Usually, you remove your shower head, install the filter, and then reinstall your shower head. In many cases, the filter is replaceable in these types of filtration devices. The size of these filters is usually no bigger than a soda can or a large cup of coffee. They also usually weigh under a pound so they are not going to wear you out if you install one on your removable shower head.

o In-line and Showerhead Filters - this combines the previous two types of water filters. Usually, the filter is actually located on the inline portion and the showerhead is a bonus that you get. Again, if you're looking to upgrade your shower head and you don't like the idea of taking a showerhead apart to replace the filter, this type of kit is probably best.

  • Material

Filters are usually made of either ABS plastic or metal. You are usually only going to find your shower head filters being made out of metal because of the extra weight.

o Plastic - the benefit of a plastic shower filter is that it's lightweight, and usually much cheaper. That means that it will be less expensive to replace it if you should happen to crack it while you are replacing the filter. On the other hand, plastic water filters are generally less durable than their metal counterparts. 

Best Shower Filter Reviews

So it depends on what type of filter you plan on getting and who will be using it. If it's just you and you don't have the tendency to bang your new filtering shower head around a lot then plastic will be fine. If you have kids or a significant other who is less than careful then consider investing in and the more durable metal option.

o Metal - as we sat metal shower filters are more durable but they are also more expensive. They are usually made of a corrosion-resistant material such as stainless steel, which gives you a better aesthetic than a white plastic housing. So if you prefer the aesthetic and decor of a shiny chrome or stainless steel fixture then, by all means, the extra cost will be a good investment for you.

  • Filter Types

Knowing how filtration works and knowing what type of filter is in your shower filter can help you separate the plausible claims from the implausible. Here are some of the various types of filters that you may find in your shower filter.

o Multi-level Carbon Filters - this is another name for granulated activated carbon filters. These filters are good for removing about 70 to 90% of the chlorine from water. On the other hand, they aren't very good for showers because when exposed to hot water the carbon tends to disintegrate fairly quickly. And when it disintegrates, the carbon will clump and clog your shower leading to very low water pressure at best and a complete backup at worst. If you like taking cold showers, then a water shower filter that relies on activated carbon will be good. For the rest of us, we would point to the KDF filter for chlorine and heavy metal removals.

o KDF Filters - KDF stands for kinetic degradation fluxion. This type of filtration media is made of copper and zinc granules that eliminate contaminants in water by using an oxidation and reduction reaction. They are primarily used to reduce heavy chemical contamination, and remove chlorine and hydrogen sulfide. The most common type of KDF media is KDF 55 which is a medium-fine granule. The scale increases in number up to 85 and even F or C grade which can be used in different applications.

KDF 55 removes over 99% of free chlorine by reducing to dissolve chlorine gas into water-soluble chloride ions. This media can also remove up to 98% of water-soluble ions of Lead, Mercury, copper, chromium, and nickel. The metals coat the media while they are being removed from the water and can be recovered by passing the KDF through a smelter. Hands down, this is one of the best shower filters for hard water

o Vitamin C Filters - the science behind vitamin c filtered water is a little suspect. Vitamin C is excellent for treating scurvy, and for helping your body heal bruises. But as far as having a significant effect when used in your shower filter, the results are still out. While it is true that vitamin F could help build collagen to strengthen your hair and help your skin, if you are eating a well-balanced diet, you were getting more than enough vitamin C to do this.

If you're wondering when the trend started, it happened in about 2014 when the MGM Grand hotel in Las Vegas created the first vitamin C-infused shower in its "Stay Well" rooms. Since then, the trend has taken off, but the science has yet to prove any long-lasting benefits for this type of shower filters.

  • Longevity

When we speak of longevity, we are talking about how long the filters last. The longer that a filter lasts, the longer you can go between replacements. You should look for a filter that is designed to last at least 6 months. Usually, with a 6-month filter, that's about 10 to 12 thousand gallons of water.

Best Shower Filter Reviews

There is a caveat there, however. If you have exceptionally hard water, or if your well has less than perfect water then you could see your filter run out before the predicted life. That's because filtration devices have a finite amount of filtration that they can do. The harder the water or the more impurities that are in it the faster that the filtration life will be expended.

  • Warranty 

A warranty usually only applies to showerhead filtration devices because they are the only ones that will be around for longer than 6 months. However, a satisfaction guarantee is equally important. Because if you purchase a filter, and you're not satisfied with how it works, then you want to know that the manufacturer will refund your money. Look for water filters that come with this type of guarantee. While not technically a warranty, it definitely fits under this category of things to pay attention to.
