Molecular air filters: Innovative technology for superior air purity

In situations where conventional particle filters reach their limits, molecular filters provide an effective solution. This advanced technology removes microscopic contaminants that are invisible to the naked eye by using adsorption – a physico-chemical process. Specifically designed to eliminate gases such as ozone, volatile organic compounds (VOCs), acids, bases, and solvents, molecular filtration is also highly effective for odour removal. As one of the world’s leading filtration companies, we offer a wide range of molecular air filters tailored to various applications. Our innovative filter products stand out for their exceptionally high efficiency and reliability, ensuring optimal air quality in diverse environments – from cleanrooms and industrial facilities to building ventilation systems.

Advantages of molecular filtration at a glance:

  • Comprehensive protection for people and machinery through effective pollutant removal
  • Prevention of corrosion and safeguarding of valuable products, processes, and artefacts
  • Promotion of health, motivation, and productivity
  • Increased efficiency of machinery and production processes
  • Reliability in diverse environments, from cleanrooms to industrial facilities
  • Prevention of odours and toxic air pollution

Technological foundations of molecular air filters

MANN+HUMMEL relies on high-quality, coconut-based activated carbon as the primary adsorption medium. Through a precise process of carbonisation and activation, a finely structured pore system is created. The resulting immense internal surface area – comparable to the size of a football field in just a teaspoon of activated carbon – enables exceptionally efficient binding of pollutant molecules via Van der Waals forces. Additionally, the activated carbon can be regenerated through controlled heating, highlighting this sustainable solution as part of MANN+HUMMEL's commitment to eco-friendly and high-performance filtration technologies.

For specific applications, the activated carbon is selectively impregnated with acids or bases. This targeted modification allows effective adsorption of both standard gases (e.g., VOCs) and more chemically challenging pollutants. This creates an optimal balance between general and specialised filtration.

Certain gases, such as ammonia or amines, however, require specialised filtration methods. In such cases, MANN+HUMMEL uses ion exchange resins. These tiny polymer-based beads bind pollutants selectively and complement activated carbon perfectly, enabling even the most demanding challenges in molecular filtration to be met.

Gas filtration / Gas adsorption

We develop customised solutions for the molecular filtration of gases using our extensive range of activated carbons. At MANN+HUMMEL Air Filtration, our customers and partners can select products from our own filter media production range that effectively and reliably adsorb harmful gases such as ozone, nitrogen oxides, and many others.

Corrosion - what is it?

It is easier than you think to detect and eliminate the risk of corrosion by using Carboactiv Corrosion Coupons for determining the harmful gas load and by utilizing molecular air filters made by MANN+HUMMEL.

Corrosion protection

Our anti-corrosion filters prevent damage from moisture, chemicals and particles, extending the life of HVAC systems and ensuring reliable performance. Trust our air filtration solutions for superior equipment protection.
