Activated carbon filter

coated with Nano particle

Activated carbon filters are small pieces of carbon, typically in granular or powdered block form, that have been treated to be extremely porous. It is so cavernous, in fact, that just one gram of activated carbon can easily have a surface area of around 32000 sq. ft. . Vast surface area enables these carbon filters to adsorb exponentially more contaminants and allergens than traditional carbon.


Activated carbon, also called activated charcoal or activated coal, is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for adsorption or chemical reactions. The word activated in the name is sometimes substituted by active. Due to its high degree of microporosity , just one gram of activated carbon has a surface area in excess of 500 m (or about 2 tennis courts), as determined typically by nitrogen gas adsorption. Sufficient activation for useful applications may come solely from the high surface area, though further chemical treatment often enhances the adsorbing properties of the material. Activated carbon is usually derived from charcoal. Properties of activated carbon include:

Key Features

• Has a capacity for virtually any vapor contaminant; it will adsorb some of almost any vapor.
• Has a large capacity for organic molecules, especially solvents.
• Will adsorb and retain a wide variety of chemicals at the same time.
• Works well under a wide range of temperature and humidity conditions.
• Adsorbs odors and chemicals preferentially to moisture. It is not a desiccant and will release moisture to adsorb chemicals.
• Can be used as a carrier of one material to attract and hold or react with another material.
• Is inert and safe to handle and use.

Activated carbon can be enhanced and impregnated and/or custom blended to be a more specialized adsorbant.
The Amount of Carbon Matters
Activated carbon adsorbs to it’s surface. When there is no more surface left to adsorb to the carbon, it is depleted of its capability to be effective. Large amounts of carbon will last longer then small amounts because it has larger amounts of surface area for adsorption. Also, depending on amounts of pollutants being adsorbed, a small amount of carbon can be depleted within weeks making it useless.
The Thickness of Carbon Matters
The more contact time carbon has with a pollutant, the better chances of it adsorbing it. The thicker
the carbon filter the better the adsorption. If the pollutant has to go through a long maze of activated
carbon, it’s chances are better of being adsorbed. That means that thin carbon filters that are used in
inexpensive air purifiers are not very effective at removing chemicals, fumes and odors from the air.
Airfit air filters are thick enough to do the work efficiently and give you the best Clean Air. Airfit Active
Carbon filter are thick enough remove all the impurities for air.

Electrostatic fibre filter Media

The Electrostatic Washable Air Filters trap up to 95% of airborne dust and allergens. They are a self-charging electrostatic filter media so they do not require any electricity.They are very easy to maintain and you save money by avoiding the need to buy expensive air purifiers.
Electrostatic filters are filters that use static electricity make the perfect air cleaner.

 The charge is generated by the air that is flowing through the static prone fibers of the filters and the airborne particles and animal dander in the home are attracted and captured by the static charge until the filter is either washed and reinstalled or replaced.

Electrostatic filters are not “lifetime,” which means you are still required to purchase replacements after one year. Electrostatic filters can be taken out and washed with clean water, air dried, and then reinstalled over 3-4 times in a year.These filters are ideal for people that suffer from allergies or asthma because it helps eliminate these pollutants and allergens while rendering higher air quality and air purification for your environment.

Key Features
• Washable and Reusable
• Anti-Microbial
• Self-charging electrostatic filter
• Reduces pollen, dust, and airborne pollutants
• Eco-friendly
• They are self-charging and do not require electricity
• Does not block or reduce airflow
