filterFitted Face Mask Felt Filter - 100% merino wool felt face mask filter. This is my choice for an effective, safe, reusable and breathable barrier layer of protection to your double layer cotton face mask. Many household materials are being considered for filter use, but have not been tested to be safe or effective. Felt is one of the components in the N95 mask and this felt is 100% merino sheep's wool. It is certified to be free of any harmful or toxic chemicals. OKEO-TEK Standard 100 certificate #990585, made in the EU. Certified Cradle to Cradle.
Your filter is easy to insert in the side pockets. Remember to remove when washing your mask in HOT water. Experts now believe ironing your mask with a HOT iron will disinfect it. Re-insert the filter for added protection.
