What is the ONDU toxicity quiz?

The ONDU toxicity quiz is an interactive tool on our platform that helps you assess how much exposure you currently have to synthetic and potentially harmful fabrics in your daily life. It asks simple questions about what you wear to work out, what you sleep in, and what materials dominate your wardrobe, then generates a personalized score with actionable recommendations for reducing your exposure.

The quiz is not meant to scare you — it is designed to raise awareness. Most people are surprised to learn how much polyester and chemically treated fabric they come into contact with each day without thinking about it. The results include specific product swaps from ONDU-curated brands that can help you transition to cleaner, natural-fiber alternatives.
