Eco Chic Face Cover Filters (x5 PM 2.5 filters) Designed to fit snugly into the front pocket of your Eco Chic Face Cover, these filters help to filter out harmful pollutants from the air. Each filter can be worn continuously for between 16-20 hours, and if they are used occasionally, they can last up to a week. Each filter is made from five layers of melt-blown, spun-woven, and activated charcoal filter cloth, which absorbs harmful gases and prevents particles above 2.5 micrometres from passing through. This pack includes 5 filters (each filter measures 12x8cm). These filters are designed to be used with Eco Chic Face Covers ONLY (Face Covers sold separately). Please note: Due to the nature of our Reusable Face Covers as a hygiene product, we are unable to accept returns on these items. The Eco Chic® Range Designed with both you and the planet in mind, Eco Chic is a stylish collection of eco-friendly fashion bags & homeware gifts. Each product is made from 100% recycled or sustainable materials that reduce landfill and are kinder to the environment. These colourful products don’t scrimp on style either. Featuring eye-catching designs, each bag, cup for bottle is built to last so it can be reused again and again.
