Cover your pillows with a dust-mite control pillow cover for the ultimate in health and comfort! These high quality pillow encasings are breathable, cool and comfortable, yet provide excellent protection against the negative effects that dust mites have on allergy and asthma sufferers. These pillow encasings are constructed with such a tight weave that they need no membrane (membranes do not breathe and can be uncomfortable to sleep on). Make sure to cover your mattress, boxsprings and comforters as well.
