Pillow Covers

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.
mattress encasing flow If you wake up in the morning with itchy, watery eyes, nasal stuffiness, runny nose, and in some cases asthma you may be allergic to dust mites and their allergens. These allergic reactions to dust mite allergens can be a year round problem.

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.

  • 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.


  • Made from synthetic fiber.
  • Does not offer waterproof protection.
  • Larger size encasements do not have seamless construction. The following mattress covers will have a seam in them: 9-inch mattress cover in queen, king, cal king, 12-inch mattress cover in full, queen, king and cal king, 15-inch mattress covers in all sizes.


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. It has a small, 5.7 micron pore size that provides great protection against dust mites and their allergens. Pristine® dust mite covers are cool, quiet and breathable to sleep on and are unnoticeable under your sheets. A huge benefit of the Pristine® fabric is it can withstand frequent laundering and still retain its tight weave and small pore size. One more thing to note, the larger size mattress covers will have a seam in them as the fabric is only made 66 inches wide. This will not bother most people because the covers are covered by your sheets, but is worth noting for those who are picky about seams.
