The U-GO Carbon Filter 4" 100mm x 300mm is a compact activated carbon air filter built around carefully selected Pro Grade 4/8 carbon, combining effective odour adsorption with high airflow and low restriction.
Activated carbon is a natural material, so its quality and particle characteristics can vary from batch to batch. U-GO takes a selective approach to the carbon used in its filters, stating that it purchases only the premium 20% of carbon produced.
The carbon is independently batch tested, de-dusted and selected before use. U-GO specifies Pro Grade 4/8 activated carbon, with material that is excessively fine, dusty or fails its required air-stream testing rejected rather than used within the finished filter.
With a 100mm / 4" connection and compact 300mm filter body, this model provides the U-GO filtration approach in a space-efficient format for smaller 100mm extraction systems.
Why choose the U-GO 4" Carbon Filter?
- Premium carbon selection - U-GO states that only the premium 20% of carbon produced is selected for its filters.
- Pro Grade 4/8 activated carbon - selected particle characteristics designed to balance effective adsorption with good airflow.
- Independently batch tested - carbon quality is assessed before being accepted for use.
- De-dusted carbon - selected and prepared to minimise excessive fine carbon material.
- Minimum 20% butane adsorption test requirement - carbon failing U-GO's stated air-stream testing standard is rejected.
- Low-restriction filtration - designed to maintain strong airflow through the carbon bed.
- 100mm / 4" connection - integrates with compatible 100mm fans, ducting and ventilation fittings.
- Compact 300mm body - ideal where available installation space is limited.
- Effective odour adsorption - activated carbon captures suitable gaseous odour compounds from extracted air.
- Designed for filtered extraction - pairs with an appropriately specified 100mm extraction fan.
Premium selected Pro Grade 4/8 carbon
Carbon quality has a major influence on the performance of an activated carbon filter. Natural carbon can vary in particle size, dust content and adsorption performance, which is why U-GO places particular emphasis on the material selected for its filters.
U-GO states that it purchases only the premium 20% of carbon produced. The selected material is independently batch tested, de-dusted and checked before being used within the finished filter.
The filter uses Pro Grade 4/8 activated carbon. Particle characteristics are important because the carbon bed needs to provide extensive adsorptive surface area while still allowing air to travel through efficiently.
Carbon that is excessively fine or dusty can create unnecessary airflow resistance. U-GO's selected 4/8 grade is intended to provide an effective balance between odour filtration and airflow.
Independently batch tested carbon
Rather than assuming every batch of activated carbon has identical characteristics, U-GO states that its carbon is independently batch tested before selection.
The process assesses the carbon for characteristics required for effective air filtration, with U-GO specifying a minimum 20% butane adsorption requirement.
Carbon that is too small, excessively dusty or does not meet the required air-stream testing standard is rejected rather than being used within the finished filter.
This quality-control process is intended to provide more consistent filtration and airflow performance throughout the U-GO carbon filter range.
How activated carbon removes unwanted odours
Activated carbon contains a vast network of microscopic pores. This creates an extremely large internal surface area relative to the physical amount of carbon inside the filter.
As odour-bearing air passes through the carbon bed, suitable gaseous compounds adhere to the carbon surface through a process known as adsorption.
Carbon quality, airflow, contact time and contaminant concentration all influence the effectiveness of this process.
The U-GO filter is therefore primarily designed to treat gaseous odour compounds carried within extracted air rather than simply acting as a dust or particulate filter.
Designed for airflow with low restriction
Every activated carbon filter introduces some resistance because the extraction fan has to draw air through a packed carbon bed.
U-GO's use of selected Pro Grade 4/8 carbon is intended to provide the particle characteristics needed for effective adsorption without creating unnecessary restriction.
This becomes important when designing a complete ventilation system. An extraction fan's maximum airflow will normally reduce once a carbon filter, ducting, bends and other ventilation components are connected.
A low-restriction carbon filter helps preserve more of the fan's available airflow while still providing the activated carbon required for effective odour filtration.
Compact 100mm x 300mm format
This model combines a nominal 100mm / 4" connection with a 300mm filter body, making it the compact option for smaller-diameter ventilation systems.
Its short body is particularly useful where available installation space is restricted and a larger carbon filter would be difficult to accommodate.
Using matching 100mm ducting, fans and ventilation fittings wherever practical helps maintain a consistent airflow path without introducing unnecessary reducers.
Filter selection should take into account the extraction fan, required airflow, available space and resistance of the complete ventilation system rather than connection diameter alone.
Installing the U-GO 100mm Carbon Filter
In a typical filtered extraction system, environmental air is drawn through the carbon filter before entering the extraction fan. The treated air then continues through the exhaust ductwork.
Fan and filter performance should be considered together. The fan needs sufficient pressure capability to overcome resistance from the carbon filter and ductwork while maintaining the required ventilation rate.
- Support the filter securely and independently.
- Use 100mm ducting and fittings wherever practical.
- Match the extraction fan appropriately to the filter and required airflow.
- Keep duct runs as short and direct as possible.
- Minimise unnecessary tight bends and reductions.
- Secure connections to minimise untreated air bypass.
- Keep the filter's air-entry surface unobstructed.
Carbon filter life & replacement
Activated carbon has a finite adsorption capacity. As contaminated air passes through the filter, gaseous compounds progressively occupy available adsorption sites within the carbon.
U-GO's selected carbon and low-restriction design are intended to provide effective filtration and a longer expected operating life, but actual service life depends on the installation and operating conditions.
Operating hours, airflow, contaminant concentration and environmental conditions can all influence how quickly the activated carbon becomes saturated.
If unwanted odours begin passing through despite correct ventilation operation and secure connections, the carbon may be approaching the end of its effective adsorption capacity.

U-GO 4" 100mm x 300mm Carbon Filter FAQs
What type of activated carbon does U-GO use?
U-GO specifies selected Pro Grade 4/8 activated carbon for its carbon filter range.
What does Pro Grade 4/8 carbon mean?
It refers to the selected particle grade used within the filter. Particle characteristics influence both adsorption performance and resistance to airflow through the carbon bed.
Why does U-GO select only part of its carbon supply?
Activated carbon is a natural material and quality varies between batches. U-GO states that it purchases only the premium 20% of carbon produced for use within its filters.
Is U-GO activated carbon batch tested?
Yes. U-GO states that its carbon is independently batch tested, de-dusted and selected before use.
What is the minimum 20% butane adsorption specification?
U-GO specifies a minimum 20% butane adsorption requirement as part of its carbon quality testing, with material that fails the required standard rejected.
Why does activated carbon particle size matter?
Particle characteristics influence both adsorption and airflow. Excessively fine or dusty carbon can create additional resistance through the filter.
Does U-GO de-dust its activated carbon?
Yes. De-dusting forms part of U-GO's stated carbon selection and preparation process.
What size ducting should I use?
This filter has a nominal 100mm / 4" connection, so matching 100mm ducting and fittings should be used wherever practical.
What is the advantage of the compact 300mm filter?
The shorter 300mm body requires less installation space, making it particularly useful for compact ventilation systems.
Can I use this filter with a 100mm extraction fan?
Yes. It is designed for integration into a 100mm ventilation system, although fan and filter performance should also be appropriately matched for the required airflow.
Will a carbon filter reduce extraction fan airflow?
Yes. Every carbon filter creates some airflow resistance. U-GO's selected carbon grade is intended to maintain good airflow while providing effective carbon filtration.
How does the filter remove unwanted odours?
Odour-bearing air passes through the activated carbon bed, where suitable gaseous compounds adsorb onto the enormous internal surface area of the carbon.
How long does a U-GO Carbon Filter last?
Service life depends on operating hours, airflow, contaminant concentration and environmental conditions, so there is no single replacement interval suitable for every installation.
How do I know when the carbon filter needs replacing?
If unwanted odours begin passing through despite correct ventilation operation and secure connections, the activated carbon may be approaching the end of its effective adsorption capacity.
