Zipped Pillow Protector. Bed bug and dust mite infestations are serious problems that canirritate a variety of health concerns including asthma, eczema and allergies. An AllerZip� pillow protector provides an effective barrier to infestation. Because treatments cannot reach the core of an already infected mattress/pillow, they usually need to be disposed of - but no longer. AllerZip� protects your mattress/pillow investment, and most importantly, your health. This protector is also waterproof and will protect your mattress/pillow from any liquid spills. AllerZip is part of the Protect A Bed range.
