Showers are great. They're refreshing, and they clean your body. But did you know that they can have health benefits, too? The best showerheads can help with dry hair, sensitive skin and even eczema flare-ups -- depending on the force and power behind your filter. A showerhead filter can get rid of the bad stuff in your water, but with so many to choose from, picking the right one can be daunting. That's why our squeaky-clean experts at CNET thoroughly tested shower filters from brands like GE, Sonaki and QwenchPure to find which ones best remove contaminants, chlorine and hard water minerals. They also looked at how easy they were to install, how long they'll last and, importantly, how much they cost to buy.
Our Picks
What is the best showerhead filter overall?
The Sonaki Inline Shower Filter is the best overall filter because our research found it can filter out bacteria, chlorine, heavy metals, rust and other byproducts from regular showerhead water. The internal filter system is an activated carbon filter, which is one of the most effective. It also doesn't require an extra showerhead. You can just screw it on your old one.

When it comes to filters, an activated carbon filter is the most effective choice for your showerhead. That's what you get with the Sonaki Inline shower filter.

Plus, it'll soften the filtered shower water so you can get softer hair than ever.
The Sonaki shower filter is an inline model, so you won't need to buy a separate showerhead. You simply screw the filter into the wall and the showerhead on the other side.
Best showerhead filter for removing heavy metals
QwenchPure KDF-55 shower filter
Pros
- Removes heavy metals, minerals and chlorine
- Filters can last up to 7 months
- Easy to install

You won't notice the electrical charge in your shower, but the heavy metals sure will.
Installation of the QwenchPure KDF-55 is super easy. No tools are required; it just screws in behind your showerhead. It will also act partly as a water softener, reducing the minerals in your shower water.

If you have confidence in the safety of your water but the chlorine in it causes dry skin, the Aqua Earth Vitamin C shower filter is one of the best shower filters you can buy. It will leave your skin feeling softer. Installation is a breeze; this filter can be attached to any showerhead you already have.

Factors to consider when choosing a showerhead filter
There are loads of shower filters on the market. There are a couple of key components to assess while you're shopping to make sure you choose the right model for you. Some filters will not fit your specific needs. Here's what to look for when buying a filter.
Filtering capabilities
Different types of filters work better to remove different contaminants and sediment, so when you're looking for the best shower filter, you'll want to check out what's in your water and decide what's most important for you, whether that's water softener, flow rate, if it will affect existing water pressure, shower filtration or gallons of usage.
Style
The best shower filters come in many forms. Some look like tanks you attach to your showerhead, some are built into a fixed showerhead, and others are available in a handheld showerhead. Each style is similar in effectiveness. Depending on your shower, some may be a better fit.
Lifespan
Filters don't last forever. They will have a limited lifespan before they need to be changed. Most options generally need to be replaced every six months. It's important to be prompt about replacing the filters because they become less effective as time passes.
Installation
Most of the best shower filters are easy to install, but some can be more involved than others. It's important to note the installation process before buying.
Additional features
Some filters include scented oils or vitamin C. If you are looking to take extra care of your skin or hair, look for these additional features.
Cost
Another thing to keep in mind is that athough the initial purchase for your water filtration might not be that high, you'll typically need to replace the filter or its internal cartridge every six months. So you should factor the price of replacement filters and cartridges into the cost while arriving at your budget for filters.
How we chose the best shower filters
The shower filters for this list were selected based on price, accessibility, filter quality, filter replacements and cartridge lifespans. We also took into account a product's materials, what it can potentially filter out from water and customer reviews.
Why you should buy a showerhead filter
Even if your water quality is perfectly safe, your hair and skin might still benefit from filtered water in your shower. For some people, the minerals and metals in their water wreak havoc on their hair. Water with high concentrations of minerals is known as hard water, and it runs through the pipes in many people's homes. Not sure if you have hard water? This USGS map can help.
Increasingly, people say that a filter on your shower helps with itchy and dull skin, not to mention a flaky scalp. The reported effects of hard water on your hair and skin are backed up by science. The specific minerals in hard water make it difficult for soaps and shampoos to lather and do their job so that icky feeling on your skin might actually be that it's not getting quite as clean.

A lot of the hair and skin irritation has to do with the fact that soap and hard water react to form "scum," the white sticky layer left behind on your skin after soaping up. Have you ever noticed the white residue that builds up on your faucets that's hard to clean? It's the product of calcium and magnesium in your water, and that same residue builds up on your skin, too. The scum clogs your pores and can cover the strands of your hair so that your conditioner can't do its work, making sensitive skin and high-maintenance hair worse.
It's not just the metals and minerals in water that dry out your skin. Anyone who's spent time in a chlorinated pool knows how it seems to draw all the moisture out of your body, leaving you with crunchy hair and red, dry or itchy skin.
The residual chlorine in shower water can create the same problems but on a much smaller scale, leaving you with skin that isn't quite as soft as you'd like. Keep in mind that the chlorine is hard to remove from water, so you'll want to make sure the shower water filter you buy is capable of removing it.
Are there toxic metals in your household water?
Many countries, including the US, have guidelines to ensure that the harmful chemicals in your water, and your overall water quality, are being examined and regulated.
In the US, the EPA has legally enforceable standards for all different types of pollutants in your drinking water, as well as secondary concerns that may cause skin irritation or affect your hair. Your local water supplier should produce a new Consumer Confidence Report each year, and the EPA has a public database designed to let you easily look up the most recent tap water report for your area. You can read the report and see if there are any worrisome pollutant levels in your water, but you can also rest safe in the knowledge that if any water contaminants are over their legal limit, your community will certainly be notified.
If you're especially worried about lead, one easy way to mitigate that risk is to simply run the tap water a few minutes before using it. The most dangerous amounts of lead accumulate when the water has been sitting in your home's pipes overnight, so if you flush that water out of the lines, you'll be in better shape.
Lead and chlorine in drinking water
Even if your water smells and tastes fine, that doesn't mean your tap water is free of harmful chemicals. Water pollutants fall into different categories, but the ones of primary concern in your shower water are toxic metals, chlorine (used as a disinfectant) and the byproducts that chlorine creates with any other chemicals in the water. Any of these can put a major crimp in your shower experience.
The main toxic metals that often hide in water are arsenic, lead, cadmium and mercury, all of which made the World Health Organization's Top 10 list of "chemicals of major health concern."
The lead from degrading plumbing can get into drinking water, causing public health issues.
Lead is often deemed the biggest contaminant offender, even if your water supply is pure, water slowly corrodes the lead in home plumbing systems, and the toxic metal seeps into the water. Children are at a particularly high risk for harsh chemicals and have been reported to absorb up to 50% of their lead through drinking water. Even at relatively low levels, the WHO reports, lead exposure can cause irreversible neurological issues. This is why water quality must always be a consideration.
Another main issue is connected to the chlorine that's used as a disinfectant in our drinking water. The major health concern is actually the byproducts created when chlorine reacts with natural organic matter in the water, creating harmful chemicals called THMs. You've probably heard of chloroform, which is just one common THM, and high levels of THMs act as carcinogens.
One study found that people absorbed more THMs from a 10-minute hot shower than from drinking a liter of water, so if you're concerned about this, a shower filtration system that actively removes chlorine can be helpful.
