FAQ

Dust mite allergy

A dust mite is an arachnid, invisible to the naked eye, measuring between 170 and 500 microns. There are nearly 50,000 species, but only the house dust mite is allergenic to humans. Responsible for 60% of allergy cases, these tiny creatures are not directly allergenic; rather, it is the proteins present in their droppings and the particles from their carcasses that trigger allergic reactions. To live and thrive, dust mites need warmth, humidity, and darkness. They feed on flakes, such as dead skin cells and hair, which is why mattresses are their preferred habitat.
To learn more about dust mites, see our fact sheet " What is a dust mite ?"

The symptoms of dust mite allergy can vary from person to person. However, here are the most common symptoms:

  • Sneezing
  • Nasal congestion and/or runny nose
  • Itching, watering or redness of the eyes
  • A feeling of tightness in the chest, difficulty breathing
  • Wheezing and/or coughing
  • Protect your mattresses, duvet and pillows with a cover anti-dust mite and filtering
  • Keep the room temperature at a maximum of 19°C
  • Maintain the humidity level between 40% and 55%
  • Air out the room every day for at least 15 minutes
  • Opt for a slatted bed base made of wood or metal rather than an upholstered bed base
  • Wash your bedding regularly (see the question on washing frequency)
  • Avoid dust traps such as knick-knacks, stuffed animals, open wardrobes or closets, etc.
  • Wash your child's cuddly toy regularly in the washing machine
  • Avoid plants in the bedroom
  • Avoid textiles such as curtains and rugs. If this is not possible, choose washable textiles and wash them regularly
  • Avoid having pets in the room
  • Replace carpets with washable flooring. If this is not possible, vacuum the carpet regularly and thoroughly with a vacuum cleaner equipped with a HEPA filter

Even though anti-dust mite eliminate dust mites, dust mite allergies are not caused by the mites themselves, but by a protein found in their remains (dead) and excrement. Even after the mites die, these allergenic particles remain in the bedding. This is why covers treated against dust mites are not effective in alleviating the symptoms of dust mite allergies.

covers anti-dust mite ProtecSom completely envelop your bedding (mattress, duvet, pillow, etc.) and close with a zipper protected by a fabric flap inside.

To ensure the effectiveness of anti-dust mite and facilitate their installation, it is essential to never choose a cover smaller than the bedding item you wish to protect. Therefore, it is crucial to know the precise dimensions of your bedding to select a suitable cover.

We recommend using a tape measure to check the measurements of your bedding:

  • For a mattress: for the length and width, choose the dimensions of your mattress. For the height, choose a cover whose height is greater than or equal to that of your mattress (never less). When measuring your mattress, measure it at the ends, where it is thickest.
  • For duvets and pillows: choose the dimensions of your duvet and pillows.
  • For ergonomic pillows (with thickness): measure the length, width and height, then add the height to the length and width to choose the appropriate size.
  • For a bolster: Select the length and diameter of your bolster.
  • For a mattress topper: we invite you to consult our Guide page to equip your mattress topper with a anti-dust mite ProtecSom.

Installing my anti-dust mite covers

covers anti-dust mite ProtecSom are medical-grade covers that completely encase bedding, creating an impenetrable barrier against dust mite allergens. Therefore, the condition of your bedding is irrelevant, and there's no need to invest in a new mattress. However, before installing the cover, thoroughly vacuum your mattress using a vacuum cleaner equipped with a HEPA filter, ensuring the room is well-ventilated before, during, and after the process. If possible, we recommend wearing an FFP2 mask during this procedure to minimize the inhalation of dust mite particles. For more detailed instructions on installing your cover, please consult our advice sheet.

We recommend washing your ProtecSom anti-dust mite cover before its first use. This will allow Noxaalon® covers to soften and Texaal® covers to begin shrinking (shrinkage allowances are taken into account in the construction of your cover).
