Why Mist 5-Mode High Pressure Filtered Shower Head wins, and what it beats

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 1 product it beats, so you can see exactly where the 5 points between the top and the bottom of this shower filters ranking come from.

What to watch for in shower filters

Beyond the PFAS grade, these are the things our graders recorded on the 15 shower filters in this category. We assess from materials, brand statements and published research. We do not lab-test.

  • VOCs and off-gassing

    Volatile compounds that evaporate out of a material at room temperature, which is what a new product smell is.

    Found on 1 of these shower filters. EPA

  • Microplastics

    Plastic fragments small enough to shed from a product into food, water or air without anyone seeing it.

    Plausible but unconfirmed on 5 more, meaning nobody has ruled it out. EPA

  • Heavy metals

    Metals such as antimony, nickel and chromium migrating from a material into what touches it.

    Plausible but unconfirmed on 2 more, meaning nobody has ruled it out. ATSDR

  • BPA and bisphenols

    Chemicals that harden plastic and line metal cans, and the replacements sold as BPA-free.

    Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. NIEHS

Our grade says what a filter is made of, not how much PFAS it removes. For that, NSF, IAPMO and WQA keep public registers of units certified to reduce PFAS, and we reproduce them in full on the list of water filters certified to reduce PFAS. Check a model against both.

The shower filters we would skip

Lowest scoring in this category, worst first, with the reason.

How to read these scores. PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Each grade is a model-based assessment built from published ingredient lists, materials, certifications, brand disclosures, recalls and third-party lab results where they exist. Read the full rubric to see exactly what adds and removes points.

What we check on shower filters

  • Confirmed PFAS, PTFE or fluoropolymer content, which is the heaviest penalty we apply.
  • Stain, water or grease resistant treatments, which usually mean fluorinated chemistry.
  • Whether the brand discloses what is in the product, or stays silent behind a “clean” claim.
  • Independent lab results and certifications where they exist.

The brands that have published something, and what each of them actually said, are in our record of what every brand has said about PFAS.
