The Best Shower Filter Option


A lot of people take for granted that clean water will come out of the tap every time they turn on the faucet. But that security comes at a cost. Disinfectants, such as chlorine, in the municipal water supply make water safe to drink, but they can leave behind byproducts that you might not want to bathe in. Your water supply may also contain trace amounts of heavy metals, pharmaceuticals, and bacteria, according to the Centers for Disease Control and Prevention (CDC).

Well water isn’t exempt from health concerns, either. Run-off and contamination from agricultural areas are serious issues.

Most homes without a whole-house filter system could benefit from a shower filter, regardless of the source of your water. The best shower filters use multiple layers of various materials to sift harmful chemicals, heavy metals, and other byproducts out of the water you bathe in. As the water works its way through these layers, the filtering media captures unwanted substances. Only pure water makes it through to your hair, skin, and nails.

The best shower filters last through hundreds or well over a thousand showers. They should be durable, easy to handle, and use materials that can intercept any junk in the water supply. This guide will assist you in choosing the best filter to remove possible contaminants, so you can bathe easy (and bpreathe easy) in the shower.

The Advantages of Owning a Shower Filter

Disinfectants in our water supply kill microbes and bacteria that could make you sick, but those disinfectants come with some risks. They can interact with naturally occurring organic compounds found in water and create what’s called disinfection byproducts or DBPs.

There’s a limit to how much can be in the water supply—about 50 to 100 parts per million (ppm). Small quantities probably won’t hurt you, but large amounts pose real risks. That’s why some people just don’t want DBPs in their water at all.

Exposure to DBPs and other contaminants through your water is especially intense. They can get into your lungs and your skin. The steam that billows out of your shower is full of tiny particles. Since your lungs have such a large surface area, they can grab up these tiny particles from the air during and even after a shower. (In that respect, a shower filter can even improve the air quality in your home.) You also soak water up through the pores in your skin—your body’s largest organ. A shower exposes your skin to between 10 to 20 gallons of water, far more than you could possibly drink in a day.

Research published in the Journal of Investigative Dermatology suggests that unfiltered bath water, especially hard water, may contribute to dry skin, hair loss, and nail problems. The best shower filter for your water supply can help.

  • The best shower filters help remove remaining DBPs and other contaminants from your shower water.
  • Filtered shower water may improve the health of your skin, hair, and nails.
  • Shower filters can improve the air quality in your home.

Types of Shower Filters

Different filtering media may target different contaminants or offer other benefits. Some filters are more powerful than others, and certain models may be a better fit for your plumbing. Here’s a look at the different types of shower filters on the market.

Showerhead Filter

Showerhead filters come with a built-in filtration system and are meant to replace your existing showerhead. They look like standard showerheads. You can also find handheld detachable models that contain filtration elements inside the handle. They’re a great option if you already use a detachable spray nozzle.

But these handheld devices typically don’t provide as much filtration as an inline filter. Though some do use multi-layer filtering media, which increases their capabilities. Aroma filters, also available for certain models, give the water a pleasant scent. This feature may be especially important to someone with hard water that has an eggy smell.

Inline Shower Filter

Inline shower filters are small barrels that attach directly to the pipe behind the showerhead. The filter screws onto the pipe, and the showerhead then screws onto the filter.

These types of shower filters use large, easy-to-replace filter cartridges that contain multiple layers (or stages) of filtration. Carbon, calcium sulfite, vitamin C, ceramic balls, and silver intercept bacteria, DBPs, and other unwanted substances.

Inline shower filters are easy to maintain. The body of the filter separates in halves to give you access to the filter cartridge. Cartridges last from 650 to 1,300 showers or more.

Inline Shower and Showerhead Filters

If you’re looking for the best of both worlds, you can double up on these options for even more filtration power.

Since these units use standard fittings, they will attach to each other. The water will pass through the inline filter first and remove most of the contaminants right away. Once the water makes its way to the showerhead, the built-in filter will remove any remaining pollutants.

You’ll still need to change the inline filter as recommended (after every 650 to 1,300 showers), but this modification should make the showerhead filter last longer.

Multi-level Carbon Filters

Multi-level carbon filters use several layers of carbon and other media to safely remove sediments and bacteria like chlorine, VOCs (volatile organic compounds), lead, and fluoride from the water.

Each layer targets a specific type of contaminant. Carbon, for example, removes chlorine, sediment particles, VOCs, and any foul taste or odor. A popular source for this carbon is granulated activated coconut charcoal.

Multi-level carbon filters are less expensive than other options. But, the hotter the water, the less effective charcoal filters are at removing chlorine.

KDF Filters

Slightly more expensive than a charcoal filter, KDF (Kinetic Degradation Fluxion) filters are still an affordable option. KDF filters contain copper-zinc media. They remove metals, chlorine, and hydrogen sulfide from water through a chemical process called redox.

Unless you have a chemistry degree, the redox reaction is complicated. Essentially, the KDF media transfers electrons from harmful contaminants and changes their chemical composition altogether. (KDF Fluid Treatment, Inc., provides even more reading material on the matter.) Redox essentially renders contaminants harmless.

Some filters and showerheads offer a layer of KDF filtration inside multi-layer cartridges to provide extra protection against heavy metals.

Vitamin C Filters

Though there’s some debate about its efficacy, vitamin C may neutralize chlorine that’s added to the water supply. While dechlorinating the water, vitamin C pellets inside the handle or cartridge add the powdered nutrient to the water stream.

Some argue these filters are just a luxury trend that doesn’t affect chlorine levels at all. But vitamin C is known to build collagen, so it could make a difference in the health of your skin and hair.

And there’s nothing wrong with a little vitamin C coming out of your showerhead. So if you’d like an extra touch of the antioxidant, add a vitamin C filter after your inline filter or buy a cartridge with a vitamin C layer.

What to Consider When Buying a Shower Filter

Besides the range of filter types available, you’ll want to keep a few other considerations in mind when you choose the best shower filter for your home. Think about how long the filter lasts, what it can filter out, and what the appliance is made of.

Lifespan and Replacement Filters

Filters themselves aren’t terribly expensive unless you have to replace them often. Consider a filter that uses long-lasting, affordable cartridges that are easy to find. You can use the manufacturer’s replacement filters or universal ones. Shop around and you’ll find filters that last for more than 1,300 showers.

When it comes to detachable showerheads that have media and aroma filters in the handle, be sure to find one that’s easy to maintain. You’re likely to replace the filters on these more often, so you want it to be a simple process. Some of these devices have pellets in the handle. You won’t find universal replacements for those, but you will find universal aroma filters.

Water Purification Abilities

Most filtration systems claim to be 99.9 percent effective, so don’t settle for less. But, manufacturers are pretty shy about what their filters can do specifically. They don’t want to over-promise. Still, you should know what contaminants these appliances target.

The best shower filters should aim to reduce or eliminate:

  • Heavy metals, such as iron, mercury, arsenic, cadmium, nickel, chromium, cobalt, zinc, and selenium
  • Bacteria and parasites, such as giardia and cryptosporidium
  • Chlorine, chloramine, and DBPs


Most shower filters are plastic. It lasts a long time and won’t corrode. You can even find plastic with finishes to match the other fixtures in your bathroom. Chrome options are plentiful. Choices in bronze might be a little more limited.

If you prefer to limit the use of BPA (bisphenol-A) plastics in your home, there are some models that will fit that need. BPA imitates estrogen hormones which can accumulate at unsafe levels in your body. This can cause several health issues, especially for infants.


Weight has a lot more to do with maintenance than actual filtration. Water filters are generally light out of the box. However, when you install the filter and add water, you’ve added weight. Add contaminants to that, and they get even heavier. In an inline filter, all this can put extra stress on the water pipe. The weight can bend or even break your pipe—or cause it to separate from the fitting.


Adjustable water filters may allow you to choose the rate at which the water flows and control how much water you use. Some showerheads will adjust for increased jets, pulsing massage settings, and even a rainfall setting.
