We use actual filters that are breathable. We don't use fabrics used with adhesive and heat pressed as some claim to be filters. This is an industrial strength filter used in air and water purification systems.
Filter Care: Washable, we recommend hand wash with warm or cold water. Small amount of detergent. No need to scrub. Gentle wash and rub under water will cleans the filter. Hang to Dry.
