100% Cotton Dust Mite Quilt Protector & Doona Encasement
Dust mite quilt protector — 100% cotton, zippered
A 100% cotton encasement that seals your doona inside a tightly woven barrier, keeping dust mite allergens trapped inside rather than in the air around you.
Your doona is one of the largest dust mite allergen reservoirs on the bed.
The tightly woven cotton creates a barrier against the fine particles that carry those allergens (typically 10–40 microns), while staying soft and breathable. Your normal quilt cover goes over the top.
What makes a dust mite quilt protector (encasement) effective
A tightly woven 100% cotton fabric with pores measured at around 2.7 microns — far smaller than the 10–40 micron particles that carry dust mite allergens — sewn into a full encasement and sealed with enclosed binding seams.
- Dust mite allergen barrier — pores well below allergen-particle size, so dust mite waste stays sealed inside the doona and out of the air you breathe.
- Breathable natural cotton — a woven natural-fibre fabric that breathes, with no polyurethane laminate or plastic feel.
- OEKO-TEX certified — the cotton fabric carries OEKO-TEX Standard 100 certification, tested for over 100 substances of concern.
- Enclosed binding seams — the fabric edges are sealed inside a bound seam, so the barrier stays continuous along every join.
- Full zipper closure — a zip running along one short end seals the doona inside once it’s in place.
- 4 internal quilt clamps — hold your doona’s corners in place so it doesn’t bunch when you wash or move it.
The pore-size detail (third-party tested)
Dust mite allergens are carried by fecal pellets and body fragments that typically measure 10 to 40 microns. According to test data supplied by the manufacturer, Fifth Ridge Pty Ltd, this fabric (Sample 00022) has pores measured at approximately 2.7 microns at maximum distribution (third-party capillary flow porometry, Galwick fluid) — well below that range, which is why the fabric can be used as a particle barrier. The zippered closure and enclosed binding seams keep the barrier continuous around the whole quilt. We have not independently conducted this testing; the figures are reproduced in good faith from the manufacturer.

What the research says about encasings
A 2003 randomised controlled trial published in the Journal of Allergy and Clinical Immunology (Halken et al.) tested mattress and pillow encasings against placebo encasings in children with asthma and dust mite allergy. The trial found that the active encasings produced a significant long-term reduction in dust mite allergen concentrations over 12 months.
This is a finding of that independent study, reported here for general information. Individual results vary, and this product is intended to be used alongside other dust mite reduction measures.
Who this dust mite quilt protector (encasement) is for
Best for adding a breathable cotton dust mite barrier around the doona.
Commonly chosen by
- Anyone building a dust mite barrier across mattress, pillow, and quilt
- Households adding a barrier layer under their existing quilt cover
- People who prefer 100% natural cotton over synthetic fibres
Probably not the right fit if
- You’re after a decorative quilt cover — this is a barrier layer that goes underneath
- You need waterproof protection — see our waterproof quilt encasement
How to fit it
Slide your doona inside, clip the corners with the four internal clamps, close the zipper, then put your normal quilt cover over the top.
Step-by-step fitting
- Open the zipper along the short end of the encasement.
- Lay your doona flat and slide it inside through the open end.
- Attach each corner of the doona to the encasement using the four internal quilt clamps.
- Close the zipper to seal the encasement.
- Put your normal quilt cover over the top.
Choosing the right size
Cotton has minimal stretch, so measure your doona’s actual dimensions and order the closest matching size. Encasements are sized slightly larger to allow for normal wash shrinkage. If you’re between sizes, size up — a slightly loose encasement is easier to fit than a tight one.
Care
Wash before first use, then every 3–6 months. A warm or gentle cycle — do not exceed 60°C. Skip bleach and fabric softeners.
Full care instructions
- Before first use: wash the encasement before fitting, to remove any production residues (manufacturer-recommended).
- Wash: warm or gentle cycle. Do not exceed 60°C — high heat can shrink or weaken cotton over time.
- Dry: tumble dry low/medium or air dry.
- Frequency: every 3–6 months is generally enough when a quilt cover or sheet sits on top. That top layer gets washed weekly with your bed linen.
- Avoid: bleach, fabric softeners, dry cleaning, and any oils or strong detergents.
Dust mite quilt protector (encasement) FAQs
Will this fit my doona?
Cotton has minimal stretch, so measure your doona’s actual dimensions and order the closest matching size. Encasements are sized slightly larger for normal wash shrinkage. If you’re between sizes, size up.
What’s the difference between a quilt cover and a quilt encasement?
A regular quilt cover is decorative and protects the doona from general wear. This quilt encasement fully encloses the doona inside a tightly-woven barrier fabric with a zipper that seals it inside. The encasement is the barrier layer; your decorative cover still goes over the top.
What’s the difference between this and the waterproof quilt encasement?
Both can be used as a barrier against dust mite particles. This cotton version is 100% natural cotton, OEKO-TEX certified, and more breathable, but it is not waterproof. The waterproof version has a TPU lining that also blocks liquid spills.
Will it make me hot at night?
Cotton is a natural, breathable fibre, so this encasement is among the more breathable options. It allows air and water vapour through more readily than a laminated waterproof cover, and there’s no plastic crinkle.
What does OEKO-TEX certified mean?
OEKO-TEX Standard 100 is an independent textile certification confirming the fabric has been tested for more than 100 substances of concern. It certifies the absence of those substances in the fabric; it is not a certification of suitability for any specific medical condition.
