About this product
Stay comfortable and allergy-free with this duvet that protects against bacteria and dust mites while you sleep. It's filled with anti-allergy hollowfibre that's approved by the British Allergy Foundation, which means it's been independently tested and meets their strict standards. The 10.5 tog rating keeps you warm through cooler months without feeling too heavy, and it's designed in king size to fit your mattress perfectly. The cover is made from a smooth fabric that feels soft and fresh, and the hollowfibre filling stays evenly distributed to give you consistent warmth all night long.
The anti-allergy treatment contains a biocide that actively works to reduce allergens building up over time. It's machine washable at 40C and suitable for tumble drying, so keeping it clean and fresh is straightforward. The filling bounces back after washing and maintains its shape beautifully, which means you'll get lasting comfort without it going flat. It comes with a five-year guarantee, so you can rest easy knowing it's covered for years of restful, allergy-protected sleep.

Great and Perfect for Sensitive Sleepers
I recently bought this anti-allergy duvet from Argos and I’m really impressed with the quality. It feels soft, lightweight, and very comfortable while still keeping me warm at night. Since using it, I’ve noticed I sleep better and wake up without any irritation or sneezing, which is great because I’m quite sensitive to dust. The material feels breathable and doesn’t overheat. It also fits perfectly in a standard duvet cover and washes well without losing its shape. Overall, excellent value for money and I would definitely recommend it to anyone looking for a comfortable, allergy-friendly duvet.

Comfy!
This duvet is just right! It has a perfect tog for pretty much all year round use. I find it warm and cozy on colder nights and just cool enough for warmer ones. It feels luxurious and I feel like I slept in a top hotel every morning!

Hello,
he treatment used in the Silentnight Anti-Allergy 10.5 Tog Duvet is generally considered safe for human use. The duvet is treated with a biocide to prevent the growth of bacteria and dust mites.
Active Chemical Ingredient
Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride: This is the active antimicrobial substance used to treat the duvet's hollowfibre filling.
Aegis Microbe Shield: Silentnight often uses this specific treatment (often referred to as LUROL AM-7 fiber) for its anti-allergy range. It works by creating a permanent coating on the fibers that physically disrupts the cell membranes of microbes rather than leaching toxic chemicals into the environment.
Have a nice day!
