Air Filtration

Air filters play an important role in removing harmful pollutants from the air and provides good comfort for people. Svenska Aerogel provides Quartzene® for clean air solutions.

IAQ – Indoor Air Quality

All human activities work better with clean air and a healthy indoor climate. Today, we spend almost 90% of our time indoors, and according to an investigation by the EU, the indoor air can be up to 50 times more polluted than outdoor air (ECA report n ° 23 Ventilation, Good Indoor Air Quality and Rational Use of Energy). Many public buildings such as offices, hotels, schools, universities, museums and hospitals have specific and general requirements on air quality. But these requirements apply to particles and not the molecular contaminants.
Quartzene® is a filter media with a very large specific inner surface, which makes it a highly efficient adsorbent of various air pollutants such as sulfur dioxide (SO2), nitrogen dioxide (NO2) and ammonia (NH 4), and as well as organic compounds VOCs, formaldehyde (CH2O) and toluene (C7H8).

Industrial applications

There are many industrial applications where a clean working environment is important. In certain processes, it may be enough with a few gas molecules or particles to cause serious problems, such as the manufacture of electronics semiconductors, circuit boards and hard drives. Polluted air in the manufacture of various types of drugs, foods or beverages can lead to serious effects on consumer health. Another delicate process is the painting plants where paint spraying systems require a constant supply of fresh air for both hygiene and safety.
A Quartzene® air filter can be customized to absorb a certain specific impurity by attaching active molecules to it’s large porous surface.

Health and Environment

Svenska Aerogel has a self-developed, patented manufacturing method for Quartzene® which is much more energy and environmentally friendly than the classic methods of producing aerogels. Quartzene® is made of silica which is one of the most common elements found in the crust of the earth. Silica based materials like Quartzene®, are classified as harmless to the health by the American FDA and are permitted in contact with food.


Depending on how and which pollutants are caught in the Quartzene® filter, it can either be regenerated and recycled or sent to deposits or incinerated. How often this needs to be done depends on pollution level in the liquid and the size of the filter.
