The Allersoft brand of pillow and mattress covers are easily our most popular allergy control products because they are soft, quiet, cool, low pore size and natural. This membrane free fabric is a patented, high construction piece of material. There is no urethane or "membrane" on the back of the fabric which gives it that cool, smooth, breathable feeling you get with your best sheets!

How the Allersoft King Mattress Covers Work

Allergy relief covers without membranes are defined as fabrics without any coating. Without some kind of coating, the woven fabric would act like a sieve. When we are talking about non membrane fabrics we have to discuss pore size. Pore size is the diameter of the space or hole between the threads. If the average waste particle of bed bugs is approximately 9 microns then the pore size must be less than 9. Typically, any non membrane fabric with a pore size less than 6 or 7 will block all allergens including pet dander. Remember that thread count has nothing to do with pore size. 1000 count sheets for example have more threads per square inch but the pore size is not maintained. Thus, these fabrics will do nothing to encase the allergens.
