House dust mite allergy is one of the most common allergies. These are triggered by the house dust mites and their feces. The MiPROwell® encasings are pulled over the existing pillow, duvet or mattress and sealed with the mite-proof zipper. They are available in the two fabric variants 100% polyester and in polyester & carbon. The protective covers with polyester & carbon have been shown to have an antistatic effect.
