Air Science Filters

Pay attention to Air Science filters. You can choose from a wide range of products, including carbon filters, HEPA filters, replacement ULPA filters and more.

In carbon filtering, activated carbon is utilized to remove contaminants. The filtration of gas molecules is based on adsorption: physical adsorption and chemical adsorption.

Physical AdsorptionChemical Adsorption
  • The gas molecules move into an empty area and diffuse into the pore
  • The molecules penetrate into the pores, impact the walls and are trapped
  • The number of pores present in the carbon is vast so the total surface area is large
  • The specific surface is a measure of the surface area per unit of weight (m2/g)
  • The physical process of adsorption is followed by chemical adsorption
  • It is a chemical reaction in which the two substances react together and the resultant chemical is trapped on the filter material

Please note that the adsorption efficiency of a filter depends on such factors as:

  • temperature -  The higher the temperature, the lower will be the adsorption capacity. The temperature must be maintained below 40°C.
  • humidity - The molecules of gases with low boiling points will be less adsorbed. The relative humidity must be maintained below 60%.
  • filter age - Make sure that the filter was properly stored before use. Otherwise, it will be less efficient and your health can be put at risk.
  • residence time - It is the time needed by the air to cross the filter, during which it stays in contact with the carbon. This time can be prolonged if the air speed crossing the filter is minimized.
  • evaporation rate and chemical concentration - If they are high, the filter is less efficient.

Air Science HEPA filters offer high performance protection. These self-contained filters physically capture particles larger than 0.3 microns.

The company’s ULPA filters ensure excellent performance. The filters physically capture particles larger than 0.12 microns.

Air Science is committed to quality. The company incorporates state-of-the-art technologies in the process of manufacturing. All items meet demanding present-day standards and comply with current safety regulations.

Please note that it is recommended to replace the filter in time.
