Best anti-allergy and hypoallergenic pillows 2025, tried and tested

Next claims these pillows are supercharged with anti-allergy properties. The brand utilises what it calls “HeiQ allergen tech”, which is a textile-finishing treatment that actively combats allergens, such as dust mite matter, pet hair, saliva and pollen. The pillows also have Allergy UK’s seal of approval, which is reassuring.

Comfort-wise, these pillows have a high loft, making them a particularly great option for side sleepers. Despite my family being hot sleepers and these pillows being solely made from synthetic fibres, no one overheated during testing, even on very warm evenings.

These pillows offered a robust, active anti-allergy treatment along with a comfortable night’s sleep. What’s more, the pillow eradicated my allergy-prone child’s night-time symptoms.

Silentnight has used treated fibres in these anti-allergy pillows. The filling is made from anti-allergy hollow fibre to protect the pillows from bacteria and dust mites. My son fared well with these pillows in the anti-allergy stakes, but most of the other testers found these a little warm to sleep on.

You can wash them at 40C and dry them in the tumble dryer on a cool setting, and they come out looking as good as new.

The loft on these pillows is one of the lowest, making them ideal for front sleepers. I found the pillows bounced back pretty well, but they can become a little flat over time.

They have a no-frills design, but they come at a great price for a pair, making Silentnight’s anti-allergy pillows the best if you’re on a budget.

I was astounded by the value of these pillows. Despite the budget-friendly price, they are big and bouncy – perfect for those who like to sink into a pillow.

I’m often reluctant of the “feels like down” claim, but these were impressive. Unlike feather and down pillows, the microfibre filling bounces back in the morning, holding its shape nicely, while the dense fibres help keep out dust mites and other allergens. So in some ways, they’re better than their feather counterpart. The cotton casing feels thick, too.

Back or side sleepers – or combination sleepers – will like these pillows, as they have a medium loft. The only downside is that microfibre isn’t the most cooling – if you’re a hot sleeper, or perimenopausal, you may start to overheat with these pillows during warmer nights. Having said that, microfibre is a resilient option, so these pillows will probably last well.

One of the most notable features of Brightr’s Stella hybrid adjustable pillow is its copper-infused casing. Research has shown that copper inhibits the growth of dust mites, and it has been found to have antibacterial properties, so it’s great to see Brightr incorporating it into its designs. While I am yet to test the long-term impacts of this, I did note my symptoms were alleviated, which I’ll take to mean it’s working as it should.

The adjustable design means this pillow is comfortable regardless of your sleep position. As a side sleeper who favours sturdy support, I found this to be a brilliant pillow. My husband (who sleeps on his back) removed some of the filling to suit the loft and firmness for him and also found it to be supportive and comfortable.

The inner pockets contain memory foam and polyester, neither of which is known to keep you cool. But Brightr has woven in its “solacechill cooling technology” – a fabric that absorbs heat and dissipates it away from your body. It clearly works. During testing, neither I nor my husband (who is prone to overheating at night) found the Stella pillow to be too hot.

Made with wool (which is naturally hypoallergenic and resistant to dust mites), Naturalmat’s pillow had a profound impact on my son’s symptoms – he no longer coughs for hours at bedtime, nor wakes with swollen eyelids. I was also pleased with how well it washed.

Unlike memory foam, which has poor temperature regulation, this Naturalmat pillow stays cool and comfortable, thanks to wool’s natural breathability. In terms of support, it’s firm, which I liked as a side sleeper and found that it provided ample spinal and neck support.

Having rigorously tested bedding over the years, I’ve found that Woolroom’s sleep products stand out – and its deluxe washable wool pillow is one of the best anti-allergy pillows I’ve tried. Much like Naturalmat’s pillow above, this one is filled with wool, making it naturally temperature-regulating and hypoallergenic.

It had a decent loft to it – as a side sleeper, I found it perfect and woke up with no neck ache at all. My slight gripe is that it flattens slightly after a few nights, but you can open the pillow and fluff up the filling when this happens. It also washed brilliantly during testing, but it does take a while to dry fully.

Piglet in Bed’s merino wool pillows are supremely comfortable. Not only is the filling naturally hypoallergenic, but it’s also great for hot sleepers as merino wool has thermo-regulating properties. Without getting too technical, it works to wick moisture during warm conditions to keep you warm, while it traps air and is insulating when it’s cold. I tested during a particularly hot summer night and was impressed with how well I stayed cool.

This pillow does come with downsides, however. The lanolin (a natural oil in wool) filling means the pillow has a farmyard scent to it at first. Plus, you cannot wash it – the brand instead advises that you air it out four times a year at the start of the season to keep it fresh.

That aside, my team of testers and I still loved sleeping on this pillow. For my back sleeping tester, the sturdy loft of the ‘medium’ fill was just right for supporting their neck. The front sleepers in the group of testers preferred the ‘soft’ version of this pillow.

I was so impressed with Brightr’s range of pillows that I also included the nox. Much like the Stella pillow featured above, this one pillow casing is infused with copper, which has been found to repel dust mites and bacteria.

The casing on this pillow has also been designed to dispel heat, but, even as someone who doesn’t overheat at night, the temperature-regulating effect could have been better. I would have liked to see the brand incorporate the same fabric (which absorbs heat) used in the Stella pillow here.

The pillow is adjustable. You receive two layers – a low loft and a medium loft. The former is recommended for front sleepers, the latter is best for back sleepers, and combining the two makes the perfect pillow for side sleepers. Both my husband and I tested this pillow, and we were impressed – he as a back sleeper who liked the medium loft option and me as a side sleeper who favoured the two layers combined. A great option for customising your comfort.
