How to use

Setting up your dehumidifier

  • Lift the lid of the dehumidifier and remove the two moisture absorber tablets provided from the upper part of the product.
  • Next, insert the chosen number of dehumidifier tablets by removing the tablets from their individual packaging and inserting them into the slots provided in the upper compartment.
  • Close the lid and the air dehumidifier will now be working.


  • To optimise absorption, place the Bostik Breathe moisture absorber system in an area where air circulates freely.
  • To avoid the risk of spillages, place the system in a place where it is not likely to be knocked over.
  • Refills must be replaced when fully dissolved so that the absorber can continue to function.


  • Consumption depends on the level of humidity in the room. Typically, the dehumidifier refills will work up to 4 months. When the refills have completely dissolved from the upper compartment, they should be replaced.
  • When refilling the humidity absorber, we recommend the following quantities: 2 x tablets for rooms up to 25m2, or 1 x tablet for smaller spaces.

Emptying the dehumidifier

  • To empty the moisture absorber, first, remove the upper compartment by gently lifting it up from the lower compartment.
  • Carefully empty the liquid from the lower compartment by pouring it into a sink or toilet.
  • Reassemble by placing the upper compartment back onto the lower compartment and it’s ready for use.


  • The moisture absorber can be completely dismantled for cleaning if required. We recommend washing with warm water. Once clean, reassemble as normal and it’s ready for use.
