12B Clean
At 12B Clean, we don’t shy away from anything—and I mean absolutely anything—when it comes to cleaning. Our three divisions are staffed by intelligent and highly trained people who know exactly what is expected of them.
Do you have unpleasant odors in your business premises or home? And do you want to solve this problem for good? Then an ozone treatment could be the ideal solution. This molecular technology ensures odor-free air.
Ozone treatment is a highly effective method for eliminating stubborn odors. In this treatment, an ozone generator transforms O₂ (oxygen) into ozone (active oxygen, O₃). The result of this molecular process is odorless air. After ozone treatment, the air smells fresh again. You might be thinking, “Doesn’t an air freshener do the same thing?” You’re right. But while an air freshener only works temporarily, ozone permanently removes odors.

Using our high-end equipment, we have already performed many ozone treatments in Haarlem. As a result, Haarlem smells a bit more pleasant again. Here are a few examples of situations in which our experts have successfully used ozone treatments in Haarlem and the surrounding area.
Removing nicotine odors in preparation for selling or buying a home.
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 is an effective way to combat microorganisms.
Ozone treatments are used to clean spaces such as offices, hotel rooms, and RVs.

Safety is the top priority when performing an ozone treatment. For example, no one is allowed to enter the room during the treatment. We provide the client with instructions on this in advance.
First, we adjust the room to the optimal temperature. We block off exhaust vents and seal any gaps. We also take fire alarms into account.
The next step is to set up the high-end equipment in the correct location(s). We check to make sure the area is empty and post "No Entry" signs.
A safe process is our top priority. Once the ozone treatment is complete, one of our ozone experts will stop by to open all the windows. He or she will use an ozone meter to check the air quality.
Are there any unpleasant odors you’d like to have removed? Our experts will be happy to tell you whether ozone treatment is the right solution for this. In some cases, (industrial) odor eliminators and enzymes that we use to tackle odors are a better solution. This is where our experience comes into play.
