Answer

Identification and elimination is easiest for dust mite allergens.

  • Feathered bedding should be removed and replaced with a fiber-filled product encased by dust mite–proof encasings. Such encasings can be purchased at the local stores or via mail orders. These encasings should be zip-locked and cover all surface areas.

  • A bed pad that is placed on top is not helpful and may be another source of dust mite infestation.

  • Less expensive plastic encasings may leak allergens through needle holes or between zipper teeth; therefore, more expensive dust mite–proof covers are preferable.

  • The pillow must be covered; this is even more crucial than covering the bed mattress itself because the pillow is where the patient's head usually spends most of the night. Box springs usually do not need to be covered.

  • Care should be taken to be sure the encasings are dust mite–proof. Some products may claim to be an allergy cover but may not provide the proper protection for dust mite. Also hypoallergenic bedding usually refers to the fact that the bedding is not made of feathers and does not necessarily mean that it is dust mite–proof.
