Waterproof dust mite quilt protector
Allergy specialists recommend dust mite covers.
It’s on ASCIA’s list of practical steps for reducing dust mite allergen at home — and it’s the one that keeps working while you sleep.
ASCIA recommends covering mattresses, pillows and quilts with dust mite resistant covers.
ASCIA allergen minimisation guidance — the peak allergy body for Australia and New Zealand.
Encasings produced a significant long-term reduction in dust mite allergen over 12 months.
Randomised, double-blind controlled trial. Halken et al., 2003, Journal of Allergy and Clinical Immunology.
ASCIA, the peak body of allergy specialists in Australia, recommends dust mite covers as part of minimising exposure. Neither ASCIA nor the researchers cited endorse a particular brand.
Built as a barrier
Waterproof. Breathable. Quiet.
A microporous TPU membrane sits behind a soft knitted jersey. It stops liquids and fine particles, lets water vapour through, and feels like fabric — not plastic.
0.16 µm
Our tightest barrier.
Every pore measured under 1 micron in third-party testing — the finest barrier we sell.
360°
Zipped all the way closed.
The whole quilt sealed inside the barrier — not a decorative cover with a button opening.
Dry
Waterproof.
Spills, sweat and accidents stay on the surface and out of your quilt.
0
Raw seam edges. Sealed at the seams, not just the zip.
Seams are where cheaper covers leak. Ours are folded and bound closed, so the barrier carries right to the edges.
Quiet
No crinkle.
Soft knitted jersey on the outside, so it feels and sounds like fabric — and it breathes, unlike vinyl or PVC.
What the research shows
Your quilt cover gets washed. The quilt inside rarely does.
You wash the quilt cover.
Not the quilt.
You pull your quilt up to your chin every night, and most quilts are too bulky to wash often — so the build-up inside just keeps growing.
The easier answer: zip it on once.
Dust mite allergen stays sealed in. Spills stay out.
Why a standard waterproof protector isn’t enough
Doona cover vs dust mite doona protector.
A standard waterproof protector is made for spills. A dust mite protector is made to be a barrier on every side — and the difference is in the details.
| Standard doona cover | This dust mite protector | |
|---|---|---|
| Fabric | Decorative cotton or polyester | Soft knitted jersey with a microporous TPU membrane |
| Coverage | Button or press-stud opening, made to decorate | Zipped fully closed |
| Feel | Vinyl and PVC types can crinkle and feel hot | Quiet, and lets water vapour through |
| Pore size | Rarely tested or published | Third-party tested: most common 0.16 µm, every pore under 1 µm |
| Made for | Spills | Spills and a barrier against dust mite allergen build-up |
Tested, not guessed.
How small are the gaps in the membrane?
Most of the tiny gaps in the membrane are about 0.16 microns wide, and every gap measured is under 1 micron. A micron is one-thousandth of a millimetre — far too small to see.
In plain terms: the droppings that carry dust mite allergen are more than 60 times bigger than most of the gaps in this membrane. Even the biggest gap measured is 13 times too small for them.

- 2Make the bed.Your quilt cover goes straight over the top and gets washed weekly as usual.
- 3Sleep.Wash it every couple of months, or straight away after a spill. That’s the whole routine.
Step one of a proven plan
Start with the bed. Then build on it.
A 2018 review by allergy researchers at the University of Virginia describes combining several measures as more likely to succeed than any single step (Wilson & Platts-Mills). Covers are a sensible place to start. Here is what the research says works alongside them.
Encase the bed and hot-wash weekly.
Covers on the mattress, pillows and quilt. Research found water at 55°C or above was effective at reducing dust mite populations in bedding (McDonald & Tovey, 1992).
Shop bundles ›Keep humidity below 50%.
Homes kept below 51% humidity for 17 months had 98% fewer live dust mites (Arlian et al., 2001).
Dehumidifiers ›Vacuum with a HEPA filter.
In a real-home study, intensive HEPA vacuuming cut dust mite allergen in carpets by about 81% (Yu et al., 2009).
HEPA vacuums ›Clean the air.
HEPA air cleaners are on leading researchers’ priority list for dust mite reduction (Wilson & Platts-Mills, 2018).

Waterproof dust mite quilt protector questions.
Do dust mite covers work?
The evidence is strong. ASCIA recommends covering mattresses, pillows and quilts with dust mite resistant covers, and a 12-month randomised controlled trial found mattress and pillow encasings produced a significant long-term reduction in dust mite allergen (Halken et al., 2003). They work best fully zipped, alongside weekly hot washing of sheets.
What’s the difference between a doona cover and a dust mite doona protector?
A doona cover is decorative bedding that closes with buttons or press studs. A dust mite doona protector is a zippered barrier that goes on first, under your normal doona cover, so the dust mite allergen built up inside the doona stays sealed in.
Can I still use my normal doona cover?
Yes. The protector goes on first and your normal quilt cover goes over the top, washed weekly as usual.
Will a waterproof quilt protector make me hot?
It adds a thin layer and is warmer than our 100% cotton quilt protector, though it breathes far better than vinyl or PVC. If you sleep hot, cotton is the better choice.
Does it feel or sound like plastic?
No. The membrane sits behind a soft knitted jersey, so the surface feels like fabric and doesn’t crinkle.
Is it suitable for incontinence and aged care?
Yes. The TPU membrane stops liquid reaching the quilt, and the protector is machine washable, no hotter than 60°C.
Which materials are best for dust mite covers?
A fabric whose gaps are smaller than the 10–40 micron particles that carry dust mite allergen, made into a fully zipped cover. Our two options are tightly woven 100% cotton (most breathable) and this knitted jersey with a TPU membrane (waterproof, every pore under 1 micron).
How often should I wash it? Should I wash it before use?
Yes, wash it before first use. ASCIA recommends washing dust mite covers at least every two months; your quilt cover on top gets washed weekly as usual. Wash straight away after a spill. Warm or gentle cycle, no hotter than 60°C. Skip bleach, fabric softener, ironing and hot dryers, which damage the membrane.
How long does it last, and when should I replace it?
Typically 4–5 years. Body oils and essential oils slowly break down the TPU membrane, so warm (not hot) washes help it last. Replace it sooner if the fabric tears or the zip no longer closes fully — a gap means the barrier is broken.

Not a medical product. We don’t claim this product cures, treats, prevents or relieves allergies, asthma or any medical condition. We describe the fabric’s measured physical properties as a barrier against fine particles and liquids. If you have a diagnosed condition, talk to your GP or allergist.
Barrier performance depends on the protector being fully zipped closed.
Testing. Pore-size figures are from a third-party laboratory test report provided by our manufacturer; a copy is available on request. They describe the fabric, not a guarantee of allergen reduction.
