Mattress Protectors vs. Dust Mite Covers
What do most people think when they hear mattress protector? Most would say it is a cover on the top of the bed to prevent stains or liquids from damaging the mattress. Mattress Protectors have been sold for years beginning with simple vinyl covers that would fit over your mattress like a sheet. Later, as people complained about the rustling noise of the vinyl and the fact that it did not breathe making them hot, membrane backed covers were introduced. The membrane backed mattress protector was not only washable but was vapor permeable and was able to breathe more than basic vinyl. It was also soft and lightweight and would not create any noise when moving on its surface. This product is the staple for mattress stores today who are really concerned about selling a product that is waterproof. This allows them to take the mattresses back within their trial period and sell them as new later on. Typically these covers are sold at high retails though you can find them for better prices at places like our sister site which can be found at http://www.bedwettingdirect.com/Bedguard_mattress_protector_s/30.htm
. If your focus is to have a soft, somewhat breathable, washable cover that will protect your mattress from stains or liquids then this is a great option.
The primary difference between a mattress protector and a dust mite cover is the zipper. As we stated, almost all mattress stores sell FITTED STYLE ONLY covers which fit like a sheet. To control dust mites from breeding in your mattress and as a result triggering your allergy symptoms, you need to ENCASE the mattress with a zippered cover that completely envelopes the mattress. Only when the top, sides and bottom of the mattress are covered in a certified allergen barrier fabric will it be dust mite proof. Which type of cover do you need? Since all our products are certified dust mite proof this will just be an added benefit whether you have allergies or not. The major difference between all of our fabric options is the type of barrier used to deal with the dust mites. The first uses the same polyurethane membrane found in the fitted style covers explained in the first paragraph. The second it a patented micro weave.
Again, if your focus is the protection of your mattress from stains or liquids and you have little or no allergy symptoms, we recommend the membrane cover. Our polyester Stretch knit it the softest and most popular of our membrane options. You will notice that as a factory direct retailer, our price for a total zippered encasement with a membrane is still less than what others sell for just fitted styles.
If your focus is allergy prevention and you are not concerned as much about spills onto your mattress, then we recommend a product without the membrane like our Allersoft Cotton. This product gives you total dust mite protection but gives you the maximum amount of air flow or breathability. This is great for those who are extremely temperature sensitive and get hot easily. Without some kind of coating or membrane, this 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 dust mites 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.
