What is Allergy Bedding
When compiling our
Top 5 list of “Must Have”
allergy control products, we knew that the list would not be complete without
including allergy control bedding.
Specifically, we are talking about especially designed zippered covers for the
mattress, pillow, box spring and duvet. If you have dust mite allergy, these
covers can be the difference between waking up feeling well or waking up knowing
it is going to be one of those “allergy” days.
zippered encasements cover all sides of the mattress, pillow or box spring; zip
up; and put a complete barrier between you and the allergens trapped inside.
Here is additional information that explains the different materials used in our
These covers are sewn from several types of material.
Coated Fabrics. These covers are made from a regular fabric that has been
coated with an allergy-proof material. The covers we sell are made by taking
either a polyester stretch knit fabric or a cotton polyester blend fabric and
fusing it with heat to a 1 mil thick urethane membrane. It is not the fabric
that gives you allergy protection. The urethane membrane provides the
protection. When you move on the bed, you create a cloud of particles. With
these covers on the bed, the particle rises, hits the membrane on the fabric and
then falls back down. Because you do not breathe the allergens, they cannot make
you sick. Coated fabrics are inexpensive and water resistant. However, special
care must be taken when laundering these covers to keep from damaging the
membrane. The membrane backing can be damaged by heat or strong bleach or
Microweave Fabrics. These covers are made from fabrics that have been
specially woven to act as a barrier cloth. The weave of the fibers used to weave
the fabric is so small that allergy causing particles cannot pass though when
movement on the bed causes them to become airborne. As with a coated fabric, the
dislodged particles are repelled and fall back inside the cover. Because they do
not get in the air, you do not inhale them. If you do not inhale them, they
cannot make you sick! Microweave fabrics can be made from all natural fibers,
synthetic fibers, or a blend of natural and synthetic fibers. The most common
synthetic fiber used is polyester. It is much stronger than cotton fiber and can
be woven much tighter. Keep in mind, the higher the polyester content the
tighter the fabric can be woven. The tightness of the weave is expressed as a
“Mean Pore Size”. This term refers to the average size of the space between the
fibers in the weave. If you have dust mite allergies, you want to look for a
Mean Pore Size of 8 microns or less. Every fabric sold by the Allergy Store is
well under 8 microns. Because microweave fabrics are not coated with urethane,
they are not water resistant. However, they do not need any special care when
laundering and can be much cooler to hot sleepers.
Vinyl/Plastic. These covers are made from different grades of plastic or
vinyl. The seams can be sewn or they can be heat fused. All vinyl and plastic
covers trap body heat making the sleeper warm. In addition, the plastic can make
crinkling noises while you sleep. Because even heavy-duty vinyl covers can be
easily torn, they are not terribly durable. The most common vinyl covers are
either 4-gauge or 6-gauge vinyl. This refers to the thickness of the vinyl. Do
not waste your money on 4-gauge as it is not effective for allergy control.
While vinyl is an inexpensive choice for allergy control bedding, it has more
negatives than positives. If you are looking to save money, you can use vinyl
for the box spring cover but use fabric covers for the pillows.
Non-Woven Fabric. These covers are made from a material the textile
industry refers to as “non-woven”. This means that the fibers are fused with a
heat or chemical process. The fibers are not knitted or woven as with most
fabrics. They are most commonly referred to by the method used to fuse the
fabrics. For example, the most commonly used non-woven fabric for allergy
control bedding is SMS. SMS stands for Spundown, Meltdown, Spundown; and this
refers to how the fibers were manipulated. Non-woven fabrics are generally
lightweight and inexpensive. They are not durable and most are not hot water
washable. Like vinyl, they can be an inexpensive alternative for the box spring.
No matter what type of material you choose for your
zippered allergy control
bedding, be sure to wash it several times a year. If you are diligent about
washing sheets, blankets and pillowcases weekly your zippered covers will only
need occasional washing. With each wash, take a moment to inspect zippers and
seams to make sure they are intact and the item does not need replacing.
