Our premium organic cotton dust mite-proof pillow protectors are for those who want complete allergen protection without chemicals, coatings, or a scratchy, plastic-feeling cover. Woven from tightly woven, certified organic cotton that is non-dyed, non-treated, and chemical-free, this is the cover we recommend for anyone with chemical sensitivities or a preference for natural-fiber bedding.
Allergists have been recommending allergen-proof pillow encasements long before we opened our doors in 1989 — and the organic cotton version has been a consistent favorite among customers who want the softest, most natural option available.
Why Organic Cotton?
Standard cotton goes through significant chemical processing — bleaching, dyeing, and finishing treatments that leave residues in the fabric. For people with chemical sensitivities, eczema, or skin reactions, those residues can be a problem even in a well-made cover.
AllergyCare™ Organic Cotton is grown without synthetic pesticides or fertilizers and processed without dyes or chemical treatments. What you get is pure, breathable cotton fabric — soft, quiet, and completely free of the additives that can trigger reactions in sensitive individuals.
How It Works
Dust mites, their fecal matter, and decomposing body fragments accumulate deep inside pillows over time — and those particles are the actual allergens that trigger reactions. You cannot wash them out of a pillow. The only effective solution is a complete physical barrier.
AllergyCare™ Organic Cotton Pillow Encasings fully enclose your pillow with a concealed drop zipper that leaves no gaps. The tightly woven organic cotton fabric has a mean pore size of 4.74 microns — small enough to block dust mite allergen particles, pet dander, mold spores, and pollen. From the first night, you stop being exposed to the allergens that have been affecting your sleep.

Who It's Best For

- People with eczema or skin conditions who need an untreated natural fiber next to their skin

Get the Right Size
Pillow encasings are available in Standard (20" x 26"), Queen (20" x 31"), and King (20" x 37"), each also available in a 2-pack. Choose the size that matches your pillow — a slightly loose fit is better than a tight one, since a snug cover can make the pillow feel stiff and puts extra stress on the seams and zipper.
Easy Care Instructions
Machine wash in hot water up to 140°. Do not use chlorine bleach. Machine dry on medium setting. Covers can also be washed in cold or warm water with De-Mite Laundry Additive or Allersearch Allergen Wash.
Special Note: The cover must be completely dry before placing on your pillow.
Like all 100% cotton products, this cover will shrink slightly when washed and dried for the first time. We have accounted for this and made the covers slightly larger — they will not be too small after the first wash.
Commonly asked questions
1. What is the difference between organic cotton and regular cotton pillow covers?
Standard cotton is processed with bleaches, dyes, and chemical finishing agents that leave residues in the fabric. AllergyCare™ Organic Cotton is grown without synthetic pesticides and processed without dyes or chemical treatments — making it the right choice for anyone with chemical sensitivities or skin reactions. Both fabrics provide equivalent allergen protection. The difference is in the chemical profile of the fabric itself.
2. Is this cover noisy or crinkly?
No. AllergyCare™ Organic Cotton is a micro-weave fabric — the tight weave of the cotton itself creates the allergen barrier, with no vinyl layers, plastic coatings, or membrane backing. It feels and sounds like regular cotton fabric. No crinkle, no noise, no plastic feel.
3. Is this cover safe for children and babies?
Yes. The fabric is non-dyed, non-treated, and free of VOCs, flame retardants, and synthetic coatings. It is a good choice for children with eczema, asthma, or allergies.
4. Do I need to wash the cover before first use?
No. It is not necessary. We do not treat any of our fabrics with chemicals or antimicrobial coatings. Please note that we do not accept the return of washed covers unless they are defective.
5. How often do I need to wash the cover?
We recommend washing the pillow cover once or twice a year under normal use. Your pillowcases should be washed weekly to every 4 to 6 weeks.
6. Which size should I order?
Match the encasing size to your pillow size — Standard, Queen, or King. A slightly loose fit is better than a snug one; if you're between sizes, size up.
