Most people are aware that filtering drinking water to avoid chemicals/contaminants is highly important.

However, what most people don’t realize is that shower water can be just as dangerous as drinking water.

Here is the reason why.

What is in Shower Water?

Your shower water contains a variety of chemicals, such as chlorine, as well as fungus and bacteria from your shower head. Your skin is more than just a cover for your body; it’s your largest organ and has a variety of functions.

In addition, it absorbs a lot of what you come into contact with. This is the reason why a shower filter is critical.

Chlorine is a common additive to water, which is great for killing pathogens, but also affects the delicate balance of bacteria on your skin. The following are some of the risks associated with chlorinated water, and the reason you should use a shower filter.

More Chlorine is Absorbed Through Showering than Drinking

You may not realize it but taking a shower in chlorinated water results in more chlorine exposure than drinking chlorinated water. This is usually due to the fact that shower water is usually a warmer temp, and because it’s coming into contact with more of your body.

According to experts, chlorine in your shower/bath water is more likely to enter your bloodstream because of its low molecular weight.

In addition, chlorine interacts with other things in the water to create harmful byproducts, such as THMs, including chloroform. While it’s true that the levels aren’t high enough to cause a significant problem, it’s not good to come into contact with regularly.

When absorbed through your skin, chemicals enter your bloodstream quickly, having a significant impact on your body. This is great for things that you want to enter your body, but not for those things that you don’t.

Some studies have indicated that bathing/showering in chlorinated water increases your risk of cancer and other problems.

Chemicals are Released into the Air Through Shower Water

There are some things that obviously contribute to pollution of indoor air: scented candles, air fresheners, etc. However, most people don’t realize that shower water also releases chemicals.

The heat causes chemicals to vaporize into the air at much higher levels than they’re present in the water. According to the EPA, there are high levels of THMs in the indoor air due to bath/shower water.

Shower Water Chemicals Can Irritate Your Skin

Bacteria is not only found in your gut; it’s also on your skin and mouth. Logic says that when you shower in chlorinated water, which reduces bacteria in the water, will also kill the bacteria on your skin.

Many people don’t really have noticeable effects, but others experience skin irritation, dry skin, or eczema.

Chemicals in Shower Water May Lead to Cancer and Other Issues

Following up on the first point, many of the chemicals in your water supply have been connected to a variety of cancers. These are a problem when consumed, but more of a problem when absorbed through skin or inhaled.

Of course, that doesn’t mean that it causes cancer, but indications are strong enough to warrant further investigation. At the very least, you might want to take some precautions by using a water filter in your shower.

Types of Shower Filters

There are several different types of shower filters that effectively protect you and your loved ones against chlorine and chloramines. Some filters use vitamin C, others use KDF – or kinetic degradation fluxion – and others uses carbon/charcoal. Each type of filter has some advantages and disadvantages. Below, we’ll take a closer look.

Carbon filters

A simple carbon filter is effective for removing chlorine with a small caveat – warmer temps decrease their effectiveness. This means they’re fine for filtering drinking water, but not so much for shower filters.

However, they’re not too hard on the budget and are beneficial for those who don’t typically take hot showers.

KDF filters

Another option that is budget-friendly is a KDF filter. These effectively remove chlorine, but are not that great at removing chloramines, which means they’re good options for areas that do not use chloramines.

Vitamin C filters

Vitamin C filters create a chemical reaction that changes chloramines and chlorine, making them harmless. They remove nearly all chloramines and chlorine and are beneficial for your skin.

Many users have reported that they’ve seen significant improvements in their hair and skin after using a Vitamin C filter. The disadvantage to these filters is that you must replace them every so often.


As you can see, depending on the type of water filter you use, they have a variety of functions. Either way, a water filter is good to have to improve the quality of your water.
