Is it safe to shower in chlorinated tap water daily?
Based on 1 peer-reviewed studyhome
Verdict: Use Caution
Yes, though a shower filter cuts chlorine absorption and vapor exposure.
What's actually in it
Tap water is treated with chlorine or chloramines. In a hot shower, some evaporates into breathable air and some absorbs through skin. For most adults, the exposure is manageable. For people with sensitive airways or asthma, a shower filter helps.
What the research says
A 2025 study in Food Chem showed chlorination byproducts amplify toxicity when combined with microplastics. Shower heads add plastic to the mix.
An activated carbon or KDF shower filter removes most chlorine and chloramine. Pair with a metal shower head for the cleanest setup.
