Allergy Defence Duvet

Ultimate 4-in-1 allergen protection, powered by HeiQ Allergen* Tech


Looking for relief from allergy symptoms at night? Our ground-breaking Allergy Defence Duvet offers the ultimate 4-in-1 solution for allergy sufferers. Using market-leading technology, it provides advanced allergen protection using nature’s own defence, so you can enjoy a more restful night’s sleep.

Unlike other anti-allergy bedding on the market, our Allergy Defence Duvet is powered by innovative HeiQ Allergen* Tech, an all-natural, chemical-free solution that protects against the 4 most common allergens found in your bed. This patent-pending technology is 100% biobased and reduces exposure to pollen, dust mite matter, dog, and cat allergens with the help of active probiotics. These naturally occurring probiotics break down and consume inanimate allergens, continuously cleaning them away to provide lasting freshness for your bedding. Perfect for those with allergies or sensitivities, the HeiQ Allergen* Tech treatment is free from harsh chemicals and is non-irritating to the skin.

Crafted with only the highest quality materials, the super-soft microfibre fabric harnesses HeiQ Allergen* Tech to combat allergens and the smooth, shape-retaining Smartfil® fibre fill provides comfort and warmth. This hypoallergenic duvet is designed for home washing and is durable for over 20 washes.

Complete your allergen protection with the full Allergy Defence range, including the Pillow, Pillow Protector Pair, and Mattress Protector. Please note, the 10.5 and 13 Tog King and Super King sizes require a larger capacity washing machine (10kg) and dryer.
