Waterproof Dust Mite Pillow Protector & Encasement | Standard/Queen

A waterproof pillow protector and encasement for standard and queen pillows — stretch-knit polyester jersey with a microporous TPU waterproof lining. The full-length zipper closure encloses the pillow, and the membrane's pore structure (approximately 0.16 microns at maximum distribution) means the fabric can be used as a barrier to dust mite particles in the 10–40 micron range as well as to liquids. Standard/Queen size: 50 × 75cm.

What this product is

A full pillow protector and encasement that can be used in homes where dust mite allergens are a concern. The TPU lining provides waterproof coverage for spills; the membrane's pore structure and full enclosure mean the fabric can also be used as a barrier to dust mite particles.

• How the fabric works as a particle barrier. Dust mite allergens are carried by fecal pellets and body fragments that typically measure 10 to 40 microns. The TPU membrane's pores — approximately 0.16 microns at maximum distribution — restrict these particles from passing through the fabric, and the full-length zipper encloses the pillow.
• Spill, sweat, and drool coverage. The TPU membrane is fully waterproof — useful for spills, sweat, drool, nursing, sick days, or anyone who wants the pillow itself protected.
• Used alongside other dust mite reduction measures. Encasement bedding is one piece of dust mite reduction in the bedroom, alongside regular vacuuming, hard-floor surfaces where possible, and reduced soft furnishings. If you have a diagnosed condition, discuss bedding choices with your GP or allergist.

Who this is for

This pillow protector is commonly chosen by:

• People who want a waterproof layer over the pillow and a fabric that can be used as a dust mite particle barrier
• Households needing pillow protection that handles both spill coverage and a dust mite barrier
• Parents wanting a waterproof pillow protector for spills, drool, or sick days
• People with a history of pillow stains (sweat, drool, makeup) who want to extend the pillow's life

It's probably not the right fit if:

• You prefer 100% natural fibres — see our cotton Standard/Queen pillow protector instead (cotton is more breathable, but not waterproof)
• Your pillow is a different size — see our King, Euro, or Child waterproof pillow protectors instead

What the fabric does

Dust mite allergens are carried by fecal pellets and body fragments that typically measure 10 to 40 microns. 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, which is why the fabric can be used as a particle barrier in this size range.

• Microporous TPU membrane. The membrane has pores small enough to block liquid water and fine particles, but large enough to let water vapour through. Particles inside your pillow stay inside.
• Fully waterproof. The TPU membrane blocks liquid spills, sweat, and drool.
• Full-length zipper. A zipper running along one short end seals the pillow inside.
• Stretch fit. The knitted jersey outer has noticeable elasticity, so it accommodates pillows with slightly varied loft.
• Soft and silent. The jersey outer feels like fabric, not plastic. No crinkle, no rustle.

Sizing

Standard/Queen: 50 × 75cm — fits the most common Australian pillow sizes. The knitted jersey has stretch, so it accommodates pillows with slightly varied loft.

Care

• Wash: Machine wash on a warm or gentle cycle. Avoid hot water — high temperatures can damage the TPU membrane over time.
• Dry: Tumble dry on low/medium heat or air dry. Avoid hot dryers, which can break down the TPU lining.
• Frequency: Every 3–6 months is generally sufficient when a pillowcase sits over the top to absorb daily wear. If there's been a spill or accident, wash sooner.
• Avoid: Bleach, fabric softeners, dry cleaning, ironing, and any oils or strong detergents.
• Lifespan: Over 4–5 years, prolonged exposure to body oils can cause the TPU membrane to break down. A pillowcase on top significantly extends the lifespan.

Materials and testing

• Fabric: 90gsm polyester knitted jersey outer with 0.2mm TPU (thermoplastic polyurethane) waterproof lining.
• Pore size: approximately 0.16 microns at maximum distribution (third-party capillary flow porometry, Galwick fluid).

We don't make claims that the product cures, treats, or prevents allergies, asthma, or any medical condition. What we describe is the fabric's measurable physical properties as a barrier against fine particles and liquids.

Pairs well with

• Dust mite mattress protectors — covers the mattress itself
• Waterproof dust mite quilt protector — covers the doona

Frequently asked questions

Will it fit my pillow?

Standard and queen pillows in Australia are typically 48 × 73cm. This protector is 50 × 75cm and the knitted jersey has stretch, so it accommodates pillows with slightly varied loft.

What's the difference between this and the cotton Standard/Queen 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 is a polyester knitted jersey with a TPU waterproof lining — it blocks liquid spills as well as particles and has a stretchy fit.

Does it really feel waterproof without feeling like plastic?

Yes. The TPU membrane is laminated behind a soft polyester knitted jersey, so the surface that touches you is fabric. There's no plastic crinkle and no rustle.

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 fully waterproof. Washing the pillowcase frequently and the protector when needed will keep the pillow underneath dry.

How often should I wash it?

Every 3–6 months is generally sufficient when a pillowcase sits over the top to absorb daily wear.

Is it noisy?

No. Plastic-backed protectors crinkle when you move; this has a fabric outer and is silent.
