Showering in unfiltered, chlorinated water can lead to dry skin, brittle hair, color-treated hair that turns green, or worse — increased itchiness, and allergies. But the best shower filters for chlorine will let you relax under a hot flow of water without having to worry about any of the potential negative effects of chlorine on your body. Of course, not all shower filters are equal, so there are a few things to keep in mind when you’re looking to minimize your chlorine exposure.
First and foremost, you'll want to make sure the filter actually works, and you can do that by checking to see what materials it's made of. For example, although an excellent purifier for drinking water, carbon loses its effectiveness when heated above room temperature. So unless you're willing to commit to a cold shower routine, you’ll want to make sure your filter also includes compounds like brass, copper, and zinc. These materials also go by the names redox media and KDF 55 filters, and not only are they effective at higher temperatures, they also do a more thorough jobof filtering water, since they use weak electric fields to purify, instead of relying solely on direct contact with the water.
You’ll also want to consider what kind of convenience and perks you're looking for. The most common options are an inline filter that works with your existing shower head or a combination filter plus shower head to replace your current shower head.
To help you make the best choice, here’s my roundup of the best shower filters for chlorine removal. And while you're researching, keep in mind: Most filters need to be replaced within six months on average.
