What is Nomite?

The NOMITE mark is an anti-allergen standard that indicates that a product, such as down and feather bedding, is suitable for house dust mite allergy sufferers.

According to Nomite: 

‘Long-term studies have found only extremely small concentrations of mites and allergens inside down and feather bedding.

Down and feather beds achieve, therefore, extremely positive results when compared with synthetic bedding. They are completely safe from an allergological point of view.

Bedding articles filled with down and feathers neither host house dust mites nor do they provide a source of food for them.’


Nomite duvets and pillows

scooms Hungarian goose down pillows and duvets are NOMITE approved, certifying that they are both suitable for house dust mite allergy sufferers.

Customer review for the scooms Hungarian goose down pillow by Rosemary:

“High quality anti allergy pillow. With previous pillows I woke up with a headache and stuffy nose - not any more. It is so comfortable to lie on - so supportive. I would definitely recommend this pillow for a perfect night's sleep. I love my pillow!”

Dust mite allergies

So what is a house dust mite? It's a tiny creature, related to the spider and tick that's not visible to the human eye as it measures around a third of a millimetre. Apparently, there are 47 different species! The most common house dust mite – Dermatophagoides pteronyssinus – likes to live in the humid and warm places in your house like bedding, carpets and soft furnishings.

People can be allergic to the dust mite droppings which become airborne and are inhaled causing an allergic reaction in sensitive people. Often this results in perennial allergic rhinitis, producing sneezing and a blocked or runny nose. According to Associate Professor Jonathan Peter from Groote Schuur Hospital and the University of Cape Town Lung Institute approximately 25% of people suffer from allergic rhinitis.

Scientific research has demonstrated that even if you suffer from house dust mite allergies or asthma you can enjoy sleeping with natural down and feather bedding for three key reasons: humidity, fabric and feeding.



The house dust mite needs high humidity to thrive, which it can’t find in down and feather bedding because of its thermal and climatic abilities. Down and feather duvets and pillows quickly warm up while you sleep, continuously dissipate moisture absorbed from the body and quickly decrease in humidity when aired.



Down and feather proof fabric will have a very tight weave to stop the down and feather leaking through the fabric which also stops mites from passing through, adding extra protection. The thread count of the duvet or pillow casing should be at least 246 to prevent dust mites penetrating. NOMITE® certified down and feather bedding also use down and feather proof fabric ticking, which also acts as a ‘barrier’ to the dust mite.

scooms duvet and pillow casings have 300 thread count with a special tight weave.



House dust mites mostly eat the scales of both human and pet skin. Apparently, a single human produces around 0.5 to 1 gram of skin scales every day. Several thousand mites can live off 0.25 grams for months! So down and feathers on not on the menu for the house dust mite! 


Other important bedding certifications

  • Oeko-Tex 100 - verifying that your duvets, pillows and bed linen have been tested against harmful toxins and chemicals. 
  • Downafresh - feather and down hygiene and cleanliness requirements to European standard EN 12935. 
  • Responsible Down Standard - an independent, voluntary global standard ensuring that the down and feathers come from geese that have been treated well; following the chain of custody from farm to product.
  • Egyptian cotton certificate - authentic 100% Egyptian cotton trademark for bed linen.
