cTrap is a functional cloth which improves the quality of indoor air by capturing and binding harmful airborne chemicals and particles directly at source.

Too many people feel bad when indoors in school, at the workplace or at home. The air can feel heavy to breathe or have an unpleasant smell. This can often be the result of indoor air being constantly polluted by emissions (airborne chemical substances) which are spread from building materials in walls, floors or ceilings. Disturbing emissions can also penetrate from adjacent premises via leaks in the floor/ceiling structure, such as tobacco smoke.

 Common problems are headache, respiratory problems, asthma and irritated mucus membranes.

cTrap is a unique cloth which eliminates or significantly reduces this problem. The cloth is mounted indoors as a complete covering layer on walls, floors or ceilings depending on where the emissions are originating. A choice of surface finishing may then be laid on top of the cloth. With fast installation and immediate effect, cTrap ensures a clean and healthy indoor environment, without using chemicals or consuming energy.

cTrap is the result of over 20 years of research at the Department of Laboratory Medicine (ILM – Institutionen för Laboratoriemedicin) at Lund University.

Environmentally friendly

cTrap does not contain any chemicals and functions without consuming energy.

Easy installation

The installation of cTrap is quick and easy. Please see the installation instructions.


Scientific studies show that cTrap effectively stops and binds emissions.

When is cTrap needed?

Moisture-damaged building material is a common source of hazardous substances in indoor air. Moisture expels chemicals that already exist in the material, and can also form new chemicals. The problems with these airborne emissions remain after the moisture problem itself has been rectified. Sometimes the emissions may not be moisture related, for example when tobacco smoke enters an apartment from a smoking neighbor.

It is an advantage to install cTrap as early as possible. Living in an environment with emissions in the air can lead to health problems for the users, negative exposure of the property in the media and unnecessary expenses if the problem becomes so severe that people must temporarily move out. All of this can be avoided if one takes action at an early stage.

Contact a damage investigator to get a professional assessment of the situation. If this shows that the air has an elevated level of harmful emissions, cTrap is a flexible solution which suits the majority of environments.
