What do the Clean, Low, Watch and Swap levels mean?

They are cut from a continuous concern level the app computes from the sourced claims that the chosen evidence lens shows: each claim counts its concern class, tier weight, confidence and dose relevance, combined worst-first with a decay so one serious finding outweighs many small ones, then scaled by how much of the substance reaches you in this use. Clean is below 0.35, Low below 1.1, Watch below 2.0 and Swap above that, on a 0 to 3 scale.

Is Hfpo-Da (genx) safe in indoor air?

Q: Is hfpo-da (genx) safe in indoor air?

Under the app's default Cautious lens, hfpo-da (genx) in indoor air rates Watch: worth watching; the app would list a cleaner alternative type. 3 sourced concerns count (endocrine, consensus tier; environmental, consensus tier; metabolic, emerging tier). This is research with sources, not medical advice.

Materials & packaging1 use researched3 sourced claims

Where it turns up: pfoa replacement, non-stick coatings. Detox My Life researched hfpo-da (genx) under one use, because the same substance means something different in each use. Every claim below carries its evidence tier, how sure the research is that it applies here, and the sources it cites. The level is computed by the app's own deterministic engine, so the page says exactly what the app would.

Sourced concerns (3)

ConsensusEndocrineconfidence 50%

The European Chemicals Agency (ECHA) has classified HFPO-DA as a substance of very high concern (SVHC) due to probable serious effects on human health and the environment, including suspicions of carcinogenicity and endocrine-disrupting effects.

Why here: The ECHA classification highlights the inherent hazardous properties of HFPO-DA, which are relevant to any exposure route, including inhalation from indoor air and dust.
What would have to be true: Inhalation of HFPO-DA from indoor air and dust.

ConsensusEnvironmentalconfidence 50%

HFPO-DA (GenX) is a persistent "forever chemical" that has been detected in indoor dust.

Why here: As a persistent chemical, HFPO-DA can accumulate in indoor environments, leading to potential inhalation exposure from settled dust.
What would have to be true: Inhalation of indoor dust containing HFPO-DA.

EmergingMetabolicconfidence 50%

Animal studies have linked HFPO-DA exposure to adverse effects on the liver, kidneys, immune system, and reproductive and endocrine systems, and it is considered more toxic than PFOA and PFOS.

Why here: Although many studies are based on oral exposure, HFPO-DA is detected in indoor dust and air, suggesting that inhalation could lead to similar systemic effects.
What would have to be true: Inhalation of HFPO-DA from indoor air and dust, with potential for systemic absorption.

Not researched here

The engine has no dossier for hfpo-da (genx) when cooked with heat, in cold food, as a finishing ingredient, in heated food packaging or other uses. The app researches an ingredient for the use it infers from your product, so a scan fills these in; this page only shows what has already been researched and source-verified.

This is research, not medical advice. Detox My Life shows sourced claims sorted by evidence tier. It does not diagnose, treat, or tell you to start or stop anything. Talk to a qualified professional about your health.

Scan your own. The app reads any product label with your camera, works out how you are about to use it, and researches every ingredient for that use with live sources. Every scan adds to a Detox Score for your home, where 50 is a typical home in your region, and a plan of next swaps.
