Toxic gases and smells are removed by air filters.

Did you know that indoor air may be hundreds of times more polluted than outside air, and that individuals spend up to 90% of their lives indoors? According to the World Health Organization, seven million people die each year as a result of air pollution, which includes both outdoor and indoor air. While food and water are basic human rights, clean air is not. 

Like water and food, is important for all living things. Toxic gases and scents in the air pollute our life, reduce our productivity, and, in the worst-case scenario, make us sick. Effective air purification of supply and exhaust air using individually designed filter media is a critical aspect in preventing health concerns, extending life expectancy, and lowering costs in many manufacturing processes. 

What is molecular filtration and how does it work? 

The major function of our filter medium is to use the physical principle of adsorption. The attraction forces of Van-der-Waals attract molecules to the surface of a solid. The bigger the molecule and the higher the boiling point of the molecule, the better this reversible process works. To remove light molecules with very low boiling points from the air, we apply the chemisorption method. The molecule interacts with the surface of the filter media and becomes permanently bound to it in this process. 

The solids we utilize are referred to as adsorbents, and they are distinguished by their enormous interior surface area, which is created by a complex system of pores (e.g. activated charcoal, silica gel, molecular sieves or ion exchange resins). A teaspoon (about 6 g) of activated charcoal, for example, has an interior surface area of 7.140 m2, which is roughly the size of a FIFA regulation soccer field. Given that odor molecules are about 1 nm in size, there is plenty of room to collect pollutants from contaminated air.
