What is chemical filter?


What is chemical filter?

Chemical filter is the filtration system designed to remove chemical pollutants from air or fluids, crucial for protecting both customers and machinery from contaminations.

Nowadays, environmental sustainability has become a hot topic, and companies need to actively reduce carbon emissions during their production processes to lessen the burden on the environment.

What are the main uses and advantages of chemical filter?


Chemical filter plays a crucial role in manufacturing facilities by effectively removing gaseous pollutants, reducing product defects, surface contamination, and other flaws, thereby enhancing productivity and quality. Moreover, these filters help reduce environmental pollution during the production process, cutting waste and costs, further reducing carbon emissions, fostering a positive cycle for both businesses and the environment.

For example, in the gas filtration, chemical filter is used to adsorb and remove invisible harmful vapors, odors, toxic gases, and chemical pollutants from the air, typically made from activated carbon and coconut carbon. These filters are commonly installed in HVAC systems (Heating, Ventilation, and Air Conditioning). To filter harmful substances and gases from the air, thereby protecting equipment and maintaining employee health.

In liquid filtration, water purifiers soften water and remove pollutants such as fluoride and chlorine, preventing harm from pollutants to humans or equipment.

Based on the actual performance of these two types of chemical filters, the following advantages can be summarized:

  • High capacity and efficacy
  • Long lifetime
  • Thorough purification of air and liquids
  • Large absorption area
  • Suitable for stringent IAQ requirements. (Indoor Air Quality)
  • Customized design according to customer needs and site environment.
  • Better filtration performance and adsorption efficiency for specific gases.

Three key points to consider when choosing the chemical filter.


Three key points to consider when choosing the chemical filter.

Although chemical filters are great aids for filtering pollutants, placing the most suitable filter in the right place is essential to maximize effectiveness. This article outlines three points to consider when choosing it:

Application area and pollutants

The first thing to assess is the application area and types of pollutants, such as organic gases, inorganic gases, ozone, dust, to determine if there are suitable filter materials. Only with the right choice can the highest efficiency be achieved.

System requirements and limitations

The second factor to consider is the requirements and limitations of the filter, such as airflow, pressure, temperature, etc., to ensure that the filter can fully handle the filtration of the entire plant.

It’s also important to ensure that the filter can operate properly to achieve the expected results.

Lifetime and replacement cycle

Although chemical filter has high capabilities and efficiency, It will inevitably degrade over time and eventually need to be replaced. Therefore, the lifetime and replacement cycle of the filter itself are equally important. Choosing the appropriate filter based on actual concentration detection can avoid premature replacement or the use of expired filter, maintaining optimal filtration effectiveness.

By considering the above factors, you can ensure that the selected chemical filter meets all operational requirements and environmental standards.

Various chemical filter


Chemical filter on the market is a general term, but they can be divided into two main categories based on their actual function. (the gas filtration and the liquid filtration). This article lists several filters commonly used in enterprises, factories, hospitals, and offers them for your reference!

Sponge Chemical Filter

Sponge Chemical Filter is effective in removing various acidic gases and organic pollutants, including hydrochloric acid (HCl), hydrogen sulfide (H2S), sulfur dioxide (SO2), nitrogen dioxide (NO2), sulfuric acid (H2SO4), ammonia, acylamide, and volatile organic compounds (VOCs). They are widely used in commercial buildings, hospitals, airports equipped with HVAC systems, and other areas requiring indoor air purification.

Pleated Chemical Filter

Pleated Chemical Filter is effective in removing various acidic gases and organic pollutants, including hydrochloric acid (HCl), hydrogen sulfide (H2S), sulfur dioxide (SO2), nitrogen dioxide (NO2), sulfuric acid (H2SO4), ammonia, acylamide, and volatile organic compounds (VOCs). They are widely used in commercial buildings, hospitals, airports equipped with HVAC systems, and other areas requiring indoor air purification.

Tray Type Activated Carbon Chemical Filter

Tray Type Activated Carbon Chemical Filter is a common type of chemical filter known for effectively removing pesticides, chlorine, and various organic pollutants. Although made of carbon, they are processed to form extensive pores and increase surface area, thus possessing high adsorption capacity to attract and fix chemical substances in water.

There’s even a type of backwashing carbon chemical filter, ideal for whole-house filtration systems. They are stored in large tanks, can be automatically cleaned, and reused for several years, providing good and continuous filtration effects.

Honeycomb Activated Carbon Chemical Filter

As the name suggests, Honeycomb Activated Carbon Chemical Filter is made of polypropylene formed into a honeycomb structure, filled with granular activated carbon inside the filter, effectively removing harmful gases, smoke, formaldehyde, odors, dust, and bacteria.

Chemical Filter Principle and Tech for AMC Removal


AMC, or Airborne Molecular Contamination, encompasses various acidic and alkaline gases sourced from diverse origins, including vehicle emissions, atmospheric ozone, industrial waste, chemical solvents, and volatile gases from etching processes.

Principle of AMC Removal

Chemical filters consist of multiple layers of filter cloth combined with adsorbents. When contaminated air enters the chemical filter, the filter cloth primarily filters out micron-sized dust particles, while the adsorbents play a crucial role in removing AMC.

Factors Affecting AMC Filtration Efficiency

Product Appearance Design

Apart from considering the filter size suitable for installation equipment, communication with manufacturers is essential to find the most suitable design.

Structural Design

Opting for chemical filter with a higher fold count is recommended as they offer better filtration efficiency and lower pressure drop, resulting in a longer lifespan. Manufacturers with excellent chemical filter technology are crucial in this regard.

Filter Material Coating Technology :

The composition and effectiveness of chemicals used in chemical filters vary, affecting filter quality. Choosing chemical filter manufacturers that produce their products in-house and adhere to MIT manufacturing standards can ensure a certain level of quality assurance.
