Experts agree the best way of avoiding house dust mites is to create a barrier between you and them. MiteGuard is designed to act as this barrier, it features a micron dust filter membrane that is sandwiched between two layers of inert fabric giving premier protection. MiteGuard totally encases your mattress, quilt and pillow; it is soft, extremely lightweight, durable and air-permeable, allowing body moisture and heat to pass through the fabric providing comfort and protection all night long. The products can also help overcome the need for regular hot washing of quilts and pillows and it allows the use of natural fillings (in pillows, mattresses and quilts) such as wool and feathers.
