Stellmark Allergy Protectors: Dust Mite Proof Pillow Covers, Mattress Covers, and Duvet Covers.
from 100% Cotton imported from Germany, this fabric is completely Dust
Mite Proof. It does not have a chemical finish or sprayed on backing or
any other synthetic component. Nothing but pure cotton that has been
through a special mechanical process to make it Dust Mite Proof. Pillow
Protectors have a dust flap. These covers are not allergen proof, since
an item must be almost air tight to make this claim. If putting these
covers onto existing pillows, it is recommended that the pillows get
cleaned first. This eliminates any existing dust mites getting into new
bedding in the first place, and gives you the wonderful breathability
that cotton is famous for.
These allergy & dust mite protectors are available for crib bedding (duvet cover and mattress cover), and duvet
cover, mattress cover, and pillow protectors for Twin, Twin XL, Double,
Queen, King, and Cal King. (Dust Mite Proof Pillow protectors come in Regular,
Standard, Queen, King, Euro, and Grand Euro sizing). Dust Mite Proof Mattress covers cover the entire mattress, and have a zippered opening with a dust flap. Stellmark Allergy Mite Proof Cotton.
