The Soft, Breathable, Anti-Allergen King Pillowcase Barrier.

Healthcare professionals agree that an impermeable barrier between humans and dust mites is an effective way to reduce the allergic reactions that prevent a good nights sleep. Dust mites, invisible microscopic organisms that thrive in the warm, dark, humid environments that mattresses provide, wreak havoc on millions of allergy sufferers and easily penetrate regular bedding. Our machine washable dust mite barrier bedding not only provides protection from allergens as small as 3.03 microns (a dust mite measures 250 microns), it is also a soft, comfortable, and breathable poly-cotton microfiber without the stiffness, noise, or heat retention of other anti-allergen bedding. Safe for sleepers of all ages, including infants, our bedding zips around your mattress, box spring, and pillows, and has inner seams for additional strength and protection. Maintains effectiveness even after repeated laundering. 60% polyester/40% cotton microfiber barrier. Imported.
