Pristine® fabrics are constructed of very tightly woven yarns, specially selected to give the best balance of softness, comfort, and color fastness. A unique finishing process allows these finely-textured yarns to create extremely small pores in the fabrics. These micro-pores allow air and moisture vapor to pass through, but are small enough to form a barrier to dust, dust mites, and associated allergens. Pristine® fabrics are not coated, laminated or otherwise given any finish that can come off during use.

Dust mites live in mattresses, comforters, carpeting and upholstery. These dust mite covers provide a barrier for up to 99.95% of mites and their allergens. They also protect you from mold spores that may exist in your camp or vacation home bedding.

  • Excellent barrier against dust mites and allergens with a small mean pore size of 5.7 microns.
  • Departments of Asthma, Allergy and Immunology at two leading Colleges of Medicine found that Pristine® is an effective barrier to dust, dust mites, and associated allergens.
  • Very breathable with a moisture vapor transfer rate of 1109 (cotton has a MVTR of around 900).
  • Very comfortable to sleep on, no membrane and it does not have a crinkle feel or sound.
  • Down proof fabric will not allow small down pieces or feathers to escape through the cover.
  • Zipper closures are easy to use and create a secure, sealed fit.
  • Easy to care for - safe to machine wash and dry.
  • Durable construction and fabric.
  • Pristine® fabric has been designed to remain an effective allergen barrier after repeat washings and withholds its tight weave and small pore size better than the average woven fabric. During an independent test, after 50 washes, our style of Pristine® fabric actually measured a smaller pore size of 4.3 microns.
  • Made in the USA.


  • Comforter covers do not have seamless construction. The width of the Pristine® fabric is not wide enough for a comforter cover to be made without a center seam.
  • Very sensitive skin may be irritated by the polyester fabric since it is a synthetic product.


Pristine® is one of the best know allergen barrier fabrics on the market. It is a patented, membrane free, micro-weave polyester fabric that feels nice to the touch and has a small 5.7 micron pore size to offer great protection against dust mites and their allergens. It provides a cool, quiet and breathable sleeping surface that is unnoticeable under your bedding. These dust mite covers are very durable and retain their tight weave longer than most top quality, woven allergen barrier fabrics. Pristine® dust mite covers are a good choice if you like to (or need to) wash all of your bedding often. Please note that these comforter covers will have a seam in them as the Pristine® fabric is only made 66-inches wide. We recommend using a duvet cover over the comforter cover and visually this will not be an issue; however, it is worth noting for those who are picky about seams.
