Ozone treatment is a highly effective way to eliminate stubborn odors. In this process, an ozone generator converts oxygen (O₂) into ozone (active oxygen, O₃), resulting in odor-free air. This treatment leavesyour home feeling wonderfully fresh. Unlike air fresheners, this method permanently removes odors.

Using our high-end equipment, we have already carried out a significant number of ozone treatments in The Hague. As a result, The Hague smells a bit fresher again. Here are a few examples of situations in which our professionals have successfully used ozone treatments in The Hague and the surrounding area.
Removing smoke odors, for example, in preparation for selling a home or when a home has just been purchased
Removing the smell of a corpse. When a corpse has been in a home and potentially harmful odors need to be eliminated.
Eliminates urine odors, burning odors, and other unpleasant smells.
It effectively combats microorganisms.
We use this treatment to clean spaces such as office buildings, hotels, and (stationary) RVs.

Safety is the top priority when performing the treatment. For example, no one is allowed to enter the room while the ozone treatment is being performed. We provide the client with instructions regarding this in advance.
Next, we ensure the optimal temperature for the treatment. We also seal any cracks and seal off the exhaust vents
We then set up our equipment in a strategic location (or locations). Please be reminded once again that no one is allowed to enter the room until we give the all-clear. To further emphasize this, we will place warning signs at the entrance(s) to the room being treated, indicating that entry is prohibited due to high concentrations of ozone.
Safety is our top priority. Once the ozone treatment is complete, one of our experts will come by to ventilate the room. He or she will use an ozone meter to check the air quality.
