Filtered Water and Endurance Sports – Part 2

You are an endurance athlete so you stink. What do you do about it? Of course, you take a shower after that hard workout. Unfortunately for most of us there is one element in that water linked to bladder cancer (men), breast cancer, and heart disease. It is chlorine. The good news is there is an inexpensive way to remove it and other impurities from your shower water.

In part two of this series I will share with you some of the insight I received while listening to Renegade Water Secrets and how it pertains to reducing chemical exposure in the shower.  This information was created by Kevin Gianni from and contains interviews from five top water experts throughout the world to discuss the importance of clean water for your health. You can also check out part 1 of my series which addresses drinking water.

Why is chlorine in the water?

Basically chlorine is used as a disinfectant by the water treatment plants. Since it doesn’t break down by the time it reaches our shower head, the hot water opens the pours of the skin and creates steam which causes us to both absorb and inhale this chemical. Yummy!

Here is a quick little article that references some of the dangers of chlorine.

How to remove the chlorine

There are inexpensive filtered shower heads that can remove the chlorine and other impurities. Installation is extremely easy and they will require filter replacement every six month to a year depending on the model. KDF media appears to be the gold standard with respect to shower heads.

A couple models worth looking into are Sprite and Aquasana(20% discount). Shop around for pricing.

I currently use two of the Sprite HO shower filter with shower heads ($40-$50) and have been happy with them for about two years. It is a single stage filtration system. I have one installed in our master shower and one in our secondary bathroom which we use to fill the bathtub for our son. I also like that the filter replacement only needs to be done once per year ($15-$20).

The Aquasana unit is a two stage system (will remove more impurities) and will go for about $68. The shower head is a bit bulkier since it has two stages so it is worth making sure it doesn’t cause any issues with your shower setup. This filter is recommended to be replaced every 6 months ($42).


Today, our body, mind, and spirit is constantly bombarded with various forms of toxins. For many of them we have very little choice but to hope that our being can deal with them. Chlorine is one such toxin that we can choose to reduce the impact in our lives for a relatively small price. The price is about what you would pay for a pair of running shoes a year! Think about it and then get out the door and go for a run/walk/hike/move-that-body.

Happy Training!
