Astex PRISTINE® Encasements use new patented fabric technology which creates an impenetrable barrier to allergy-causing particles produced by house dust mites, such as those responsible for asthma, eczema, rhinitis and perennial hay fever. The fibre in Astex PRISTINE® fabric has been tested by two independent US colleges of medicine and found to be an effective barrier to dust mites and their associated allergens.

Our Guarantee

BEFORE fitting an encasement, thoroughly vacuum your mattress, duvet and pillows. Wash at 60ºC every 4-6 weeks and this will get rid of surface house dust mites and tighten the fabric, keeping it effective for up to 10 years.
