  • Children between 6 and 12 years of age (birth year 2008 - 2013) received a mouth mask for kids. Belgium's federal government neither requires nor recommends young children to wear mouth masks, but our masks will offer children the opportunity to do so, if their parents so wish.

What type of mouth mask is it?

You will receive a reusable textile mouth mask that complies with the model recommended by the Federal Government (

  • The mask consists of two cotton layers. Cotton prevents allergic reactions, is easy to wash and comfortable to wear. 
  • In consultation with the University of Leuven and the manufacturer we have enhanced the model in two ways:
    • A (removable) pliable stainless rod in the upper part of the mask enables you to fit the mask to your nose arch. 
    • A combination of elastic bands and ribbons makes it easier to put on and take off the mask.

How to use?

  • Wash your hands before you put on the mouth mask and after you take it off.
  • The mask has an opening in which you can fit a filter for extra protection. You can make a filter yourself. Replace the filter after each use.
  • Wear the mask with its white side on the outside.
  • Make sure the mask completely covers your nose, mouth and chin.
  • Wash the mask on a regular basis and when it is moist or dirty. Wash the mask with soap (by hand or in a washing machine) for a minimum of 15 minutes and at a temperature of at least 60°C.
  • The coronavirus can remain on textiles for a maximum of 24 hours. If the mask is not dirty or moist, you can choose to air it out for 24 hours.

When do I wear a face covering (nose and mouth)?

  • On public transport (mandatory):
    • For everyone from 12 years old.
    • Face coverings must be worn from the moment you enter a train station station or approach a bus stop.
  • In shops and public settings where keeping a 1.5m distance from others is not guaranteed. (strongly recommended)
A mouth mask alone does not suffice for your protection and that of others. Always maintain a safe distance and wash your hands regularly.
Forgot your mouth mask?
The Federal Government requires you to wear a face covering (nose and mouth). You can use a scarf or bandana. Choose one that is densely woven and make sure it fits tight to your face and that it covers your nose, mouth and chin.

Why does the City of Leuven distribute these mouth masks?

  • We want to contribute to the federal measures to curb the spread of COVID-19. The masks will allow us to protect each other whenever keeping a safety distance of 1.5m from others is not guaranteed.
  • We want to offer you quality and safety. Therefore, we have chosen to consult with the University of Leuven in selecting the fabric used and in drafting the user guidelines. 
  • The care and healthcare sector should remain prioritised in the distribution of professional disposable mouth masks.
  • Not everyone is able to make mouth masks at home. Shops have very limited stocks and it is difficult to judge the quality of such masks. 

Which filters can you use?


  • Filters in air purifier, air conditioner or convection oven such as MERV 12, MERV13 or Hepa air filter
  • Viscose mop, microfibre dishcloths
  • Kitchen paper (folded to size, min. double)
  • Paper handkerchiefs, unfolded
  • Make-up pads (rectangular and large enough)

Less recommended

  • Coffee filter 1 sheet (not 2)
  • Microfibre cloth to polish glasses
  • Swiffer

Not recommended

  • Vacuum cleaner bag
  • Plastic bags or impermeable materials
  • Cooker hood filter
