Waterproof Dust Mite Pillow Protector & Encasement | King | AU
Dust mite pillow protector, King 51×92cm — waterproof, zippered
A waterproof encasement that seals your King pillow inside a microporous TPU barrier, keeping dust mite allergens trapped inside and blocking spills and drool.
Your pillow is one of the most concentrated dust mite allergen reservoirs on the bed.
The TPU membrane creates a barrier against the fine particles that carry those allergens (typically 10–40 microns), while remaining waterproof. Your normal pillowcase goes over the top.
What makes a dust mite pillow protector effective
A microporous TPU membrane with pores measured at around 0.16 microns — far smaller than the 10–40 micron particles that carry dust mite allergens — laminated behind a soft, silent jersey outer. Pore-size figures are supplied by the manufacturer, Fifth Ridge Pty Ltd, from third-party testing.
- Dust mite allergen barrier — pores well below allergen-particle size, so dust mite waste stays sealed inside the pillow and out of the air you breathe.
- Waterproof TPU barrier — blocks spills, sweat and drool; useful for nursing, sick days, or kids’ pillows.
- Breathable, not sweaty — the membrane is microporous, letting water vapour through so the protector still breathes.
- Full-length zipper — a zip along one short end seals the pillow inside on all sides.
- Soft, silent, stretchy — the jersey outer feels like fabric, not plastic (no crinkle) and stretches to fit varied pillow loft.
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’s TPU membrane has pores measured at approximately 0.16 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 full-length zipper encloses the pillow on all sides. We have not independently conducted this testing; the figures are reproduced in good faith from the manufacturer.

| Size | King — 51 × 92cm |
| Closure | Full-length zipper along one short end |
| Waterproof | Yes — TPU membrane blocks liquid spills |

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 pillow protector is for
Best for King-size pillows (51×92cm). Use one encasement per pillow.
Commonly chosen by
- Anyone building a dust mite barrier across mattress, pillow, and quilt
- Parents wanting a waterproof pillow layer for spills, drool, or sick days
- People who prefer a stretchy waterproof fit rather than a woven cotton encasement
Probably not the right fit if
- You prefer 100% natural fibres — see our cotton King pillow protector (OEKO-TEX certified, not waterproof)
- Your pillow is Standard/Queen size — see our Standard/Queen waterproof version
Sizing
King — 51 × 92cm. King pillows in Australia are typically around 50 × 90cm, and the knitted jersey has stretch, so it accommodates pillows with slightly varied loft. To fit: open the zip, slide the pillow inside, then close the zip and put your pillowcase over the top.
Care
A warm or gentle cycle is best — do not exceed 60°C. Skip bleach and fabric softeners to protect the TPU membrane.
Full care instructions
- Wash: warm or gentle cycle. Do not exceed 60°C — high heat can damage the TPU membrane over time.
- Dry: tumble dry low/medium or air dry. Avoid very hot dryers, which can break down the TPU lining.
- Frequency: every 3–6 months is generally enough when a pillowcase sits over the top. Wash sooner after a spill or accident.
- Avoid: bleach, fabric softeners, dry cleaning, ironing, and any oils or strong detergents.
- Lifespan: over 4–5 years, body oils can gradually break down the TPU membrane. A pillowcase on top significantly extends its life.
Dust mite pillow protector FAQs
Will it fit my King pillow?
King pillows in Australia are typically around 50 × 90cm. This protector is 51 × 92cm and the knitted jersey has stretch, so it accommodates pillows with slightly varied loft.
What’s the difference between this and the cotton King pillow protector?
Both can be used as a barrier against dust mite particles. The cotton version is 100% natural cotton, OEKO-TEX certified, more breathable, but not waterproof. This version has a TPU waterproof lining that also blocks liquid spills and has a stretchy fit.
Does it feel like plastic?
No. The TPU membrane is laminated behind a soft polyester knitted jersey, so the surface that touches you is fabric. There’s no plastic crinkle.
Will it make my head hot at night?
Less than a fully laminated PVC protector, but slightly more than a 100% cotton encasement. The TPU membrane is microporous — it allows water vapour through, so it breathes — but it’s not as breathable as natural fibre.
Is it suitable for kids who drool or have wet beds?
Yes — the TPU lining is waterproof, so the pillow underneath stays dry through the protector layer.
