About MaterialFilter
MaterialFilter is a search engine for natural-fiber clothing. We help shoppers find clothing by what it's actually made of — organic cotton, linen, hemp, wool — and by the certifications that back those claims.

Why we built this
Most fashion sites sort by category, color, and price. None let you filter by what your clothes are actually made of. MaterialFilter fixes that.
Every product we index is matched against its real material composition — sourced from the brand's own spec sheets — and verified against independent third-party certifications.
How we make money
When you buy a product through one of our links, the retailer pays us a small commission. It costs you nothing extra and it's how we keep the site free, ad-free, and honest.
