Top 1 Non-Toxic Shower Filter 2026

What we love

• You live in an area with known PFAS contamination in the water supply and want the only shower filter with a formal NSF/ANSI 53 PFAS certification
• Your household's top priority is the broadest possible certified protection against chlorine, THMs, and PFAS and you are willing to accept reduced shower pressure
• You already know your water is treated with free chlorine (not chloramines) and want independent lab-verified 100% chlorine removal
• You want a keep-your-own-showerhead inline installation without any plumbing changes

Worth knowing

• Your water utility uses chloramines as the primary disinfectant — activated carbon cannot reliably remove chloramine at shower flow rates and you will not be protected from your water's main chemical
• You have naturally low water pressure at home — adding a filter that reduces flow to 1.42 GPM could make your shower uncomfortably weak
• You want complete material transparency including NSF 61 certification for the filter media — Weddell has not disclosed this information
