What Makes a Pillow Hypoallergenic? A Guide for Allergy Sufferers

A pillow is hypoallergenic when its fill, cover and care make it harder for common allergens like dust mites, mould and pet dander to build up. In practice, that means a feather-free or foam fill, a tightly woven or dust mite resistant cover, and a cover you can take off and wash regularly. A hypoallergenic pillow can help, but it works best as part of a wider routine of washing your bedding and protecting your mattress.

In this guide, we'll explain what makes a pillow hypoallergenic, whether these pillows help with allergies, which suits allergy sufferers best and how to keep your pillow allergy-friendly.

Key Takeaways

• No pillow is completely allergen-free, but the right fill and cover can make it harder for allergens to build up.

• The cover matters as much as the fill, as a tightly woven or dust mite resistant cover keeps allergens away from your face.

• A removable, washable cover is one of the most useful features for anyone with allergies.

• A pillow works best alongside other steps, like washing your bedding weekly and protecting your mattress with something like our Great Barrier Mattress Protector.

• Replace your pillow when it's worn out, as older pillows collect more dust, skin and allergens over time.

What Makes a Pillow Hypoallergenic

A pillow is hypoallergenic when it's designed to reduce your contact with the allergens that commonly trigger symptoms, especially house dust mites. Three things work together to make that happen, which are the fill, the cover and how easy the pillow is to keep clean.

The word itself doesn't tell you which allergens a pillow resists or how it was tested, so it's worth looking at what's inside the pillow and how it's cared for rather than relying on the label alone.

Fill Materials That Reduce Allergens

The fill decides what kind of environment the inside of your pillow creates. Loose fills like polyester fibre, down and feathers have lots of small gaps where dust, skin cells and moisture can settle. Solid fills like memory foam, polyurethane foam and latex don't have loose fibres, so there's less space inside for dust to collect.

Feathers are often blamed for allergies, but the evidence is more mixed than you might expect. In a small study from New Zealand, polyester-filled pillows held significantly more dust mite allergen than feather-filled pillows that had been used on the same beds. So a synthetic fill isn't automatically the better choice, and the cover and cleaning routine matter just as much.

Covers & Weave That Block Dust Mites

The cover is your pillow's first line of defence. A tightly woven cover makes it harder for dust mites and their droppings to pass between the fill and your face. Dedicated dust mite resistant covers go a step further, and Australia's peak allergy body, ASCIA, recommends covering mattresses, pillows and quilts with dust mite resistant covers and washing them at least every two months.

A removable cover is just as important, because it means you can wash the part of the pillow that's closest to you without damaging the fill.

Do Hypoallergenic Pillows Actually Help with Allergies

Hypoallergenic pillows can help reduce your exposure to allergens, but on their own they're unlikely to fix allergy symptoms. Dust mites live throughout the bedroom, including in mattresses, quilts, carpets and soft furnishings, so changing just your pillow only tackles one part of the problem.

That's why ASCIA recommends a combination of steps to reduce dust mites in the bedroom. These include washing bedding weekly in hot water, using dust mite resistant covers and removing things like sheepskins and soft toys that dust mites thrive in. Research also suggests single measures have limited effect. A Cochrane review of dust mite control for asthma found that measures like mattress covers didn't improve asthma on their own.

So a hypoallergenic pillow is a good place to start, but we'd think of it as one part of an allergy-friendly bedroom rather than a fix in itself. If your symptoms are ongoing, it's worth speaking to your GP, who can help confirm what you're allergic to.

Best Pillow Types for Allergy Sufferers

The best pillow for allergy sufferers is one with a fill that's easy to keep clean and a removable cover you can wash often. Both down alternatives and foam pillows can work well, as long as you look after them.

Down & Feather Alternatives

Down alternative pillows use synthetic fibres, like polyester or microfibre, to copy the soft, squashy feel of down. They're a popular choice if you're allergic to feathers specifically, and many can be washed whole, which helps remove dust and allergens.

The trade-off is that loose fibres can collect dust mite allergen over time, so washing them regularly and replacing them when they lose their shape matters. If you like a soft, mouldable pillow and don't have a feather allergy, a well-cared-for feather pillow can also be an option.

Memory Foam & Latex Options

Memory foam, polyurethane foam and latex pillows have a solid core rather than loose fill, so there are fewer gaps inside for dust to settle. Most come with a removable cover, so you can wash the outside while the core stays in shape.

Our Koala Pillow is a feather-free foam pillow, with a CertiPUR-US® certified foam core and a removable, washable cover. The cover is treated with antimicrobial tech and flips between organic cotton for winter and cool-to-the-touch CoolThread® for summer. You can also adjust the firmness by zipping or unzipping each side.

If you're choosing latex, keep in mind that natural latex can trigger a reaction in people with a latex allergy, so check with your doctor first if that applies to you.

How to Keep Your Pillow Allergy-Friendly

The best way to keep your pillow allergy-friendly is to protect it, wash it often and replace it when it's worn out. These habits make a bigger difference than the pillow alone.

Use a Hypoallergenic Pillow Protector

A dust mite resistant pillow protector adds a barrier between the pillow and your face, and it's easier to wash than the pillow itself. Put it on under your pillowcase and wash it regularly, as ASCIA suggests washing dust mite resistant covers at least every two months.

It's worth protecting your mattress too, as it's where you spend the most time. Our Great Barrier Mattress Protector fully encases the mattress to help keep out dust mites, dust and pet dander, and it has a zip-off top layer for easy washing. If your mattress is taller than 30 cm, our Deep Fit Great Barrier Mattress Protector is the better fit. You'll find both in our mattress protectors range.

Wash & Replace on Schedule

ASCIA recommends washing sheets, pillowcases and other bedding once a week in hot water above 60°C, which kills dust mites and washes away the allergen they leave behind. Always check the care label first. If something can't go in hot water, ASCIA suggests using a laundry product with tea tree or eucalyptus oil that's made to kill dust mites in cold water.

For our Koala Pillow, remove the cover and wash it on a cold, gentle cycle, then line dry it. The foam core shouldn't be washed or soaked.

Pillows also don't last forever. Most experts recommend replacing pillows every one to two years, while foam and latex pillows tend to last longer. Older pillows collect more dust, skin cells and allergens, so replacing yours on time helps keep your bed fresher.
