How do Astex PRISTINE^® Encasements work?

House dust mites feed on shed human skin and bodily fluids and so by fully encasing your bedding this prevents their survival. Our Mattress, Duvet and Pillow 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.

Most anti-allergy bedding on the market is either fabric treated with a chemical to kill house dust mites (effective but not long-lasting), or it is fabric backed with water proof polyurethane (which is noisy and makes the sleeper very hot). Astex PRISTINE® fabric is totally different – it is not chemically treated or plastic backed.

Astex PRISTINE® fabric has a minute pore size of 5.9 microns that prevents 99% of all allergens from passing through from pillows, duvet and mattress. We guarantee our fabric to be effective for up to 10 years washed at 60ºC every 4-6 weeks. Astex PRISTINE® Encasements have lined zip closures for extra protection.

NEW – Travel Liners are easy-to-fit elasticated mattress covers that will reduce the risk of an allergy attack when away from home. Allergy symptoms can return if the bed you are staying in has not been protected from dust mite colonisation.
Astex PRISTINE® Travel Liners are suitable for business trips, weekends or holidays away.

They are easy to fit and can be quickly placed over existing sheets in a hotel or between the hotel bed linen and mattress. As they are not fully encasing there is a chance of limited exposure to allergens but this is normally acceptable for up to 6 weeks. For long-term use and maximum secure protection always use our zipped and fully encasing Astex PRISTINE® Encasements.

All Encasements fit a maximum size UP TO the measurements stated below. For other sizes please ring for a price.
