No, our masks are washable and can be used as long as desired. We have special washing instructions to maintain the same performance for a long time.
Fill a small tub or sink with lukewarm water, put some detergent (wool shampoo/mild detergent) and place the mask. Soak for 5 minutes.
Hand washes only.
Use gentle movements to swish the item through the sudsy water. Avoid scrubbing or twisting actions that can stretch or damage the fabric.
Once you have washed the mask well, remove it from the water. Drain the tub, and refill it with clean cool water (do it for 3 times). Rinse the mask by pulling it in and out of the water until soap is removed.
Gently squeeze the excess water from the mask. Do not twist or wring it
Dry the mask on a mild temperature, where the air is circulating. Keep it away from the sun and heat.
