Healthy Body Head to Toe Organic Cotton Barrier Mattress Covers - Dust Mite Protection
The barrier cloth is designed to block dust mite excretion, animal dander, and all sorts of household dust from passing between sleeper and mattress. It's the most tightly woven natural material we carry, completely prevents airflow, and can help with a lot of other airborne chemicals based on its very small pore size. It's great to use anywhere you need to prevent dust and allergens from getting into the air; especially pillow protectors and mattress protectors, and also storage bags for bedding. Ours is not treated with urethane like many other organic barrier cloth is. 3-sided zipper.
