The U-GO Carbon Filter 6" 150mm 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.

With a 150mm / 6" connection and compact 300mm filter body, this version provides the U-GO filtration approach in a shorter format for 150mm extraction systems where installation space is more limited.

Why choose the U-GO 6" x 300mm 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 checked before being accepted for use.
  • De-dusted carbon - selected to minimise excessive fine carbon material within the filter.
  • Minimum 20% butane adsorption test requirement - carbon failing U-GO's stated air-stream standard is rejected.
  • Low-restriction filtration - designed to maintain strong airflow through the carbon bed.
  • 150mm / 6" connection - integrates with compatible 150mm fans, ducting and ventilation fittings.
  • Compact 300mm body - useful where a full-length carbon filter would be difficult to accommodate.
  • Effective odour adsorption - activated carbon captures suitable gaseous odour compounds from extracted air.
  • Suitable for filtered extraction - pairs with an appropriately specified 150mm extraction fan.

Premium selected Pro Grade 4/8 carbon

Carbon quality is one of the most important factors in an activated carbon filter. Natural carbon can vary in particle size, dust content and adsorption performance, so U-GO places particular emphasis on selecting the material used inside its filters.

U-GO states that it purchases only the premium 20% of carbon produced. The selected carbon is independently batch tested, de-dusted and checked before being used within the finished filter.

The range uses Pro Grade 4/8 activated carbon. Carbon particle characteristics matter because the filter needs to provide a substantial adsorptive surface while still allowing air to travel through the carbon bed efficiently.

Material that is excessively fine or dusty can create unnecessary resistance. U-GO's selected 4/8 grade is intended to provide an effective balance between odour filtration and airflow.

Independently batch tested carbon

U-GO states that its activated carbon is independently batch tested rather than assuming every batch of natural carbon will perform identically.

The selection process checks the carbon for the characteristics required for air filtration, including a stated minimum 20% butane adsorption requirement.

Carbon that is too small, excessively dusty or does not meet the required air-stream test is rejected rather than being used within the finished filter.

This quality-control process is intended to provide more consistent filtration and airflow performance across the U-GO carbon filter range.

How activated carbon removes unwanted odours

Activated carbon has an extremely porous internal structure. Its network of microscopic pores creates an enormous 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 this surface through a process known as adsorption.

The effectiveness of carbon filtration is influenced by carbon quality, airflow, contact time, environmental conditions and the concentration of the compounds being treated.

The U-GO filter is therefore primarily designed to treat gaseous odour compounds carried in the extraction airstream rather than functioning simply as a particulate filter.

Designed for airflow with low restriction

Every carbon filter introduces some airflow resistance because the extraction fan has to draw air through a packed bed of activated carbon.

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 matters when designing a complete ventilation system. Once a carbon filter, ducting, bends and other components are connected, the actual airflow delivered by an extraction fan will normally be lower than its unrestricted maximum airflow figure.

A low-restriction carbon filter helps preserve more of the fan's available airflow while still providing the activated carbon required for odour filtration.

Compact 150mm x 300mm format

This model combines a nominal 150mm / 6" connection with a 300mm filter body.

Its shorter format makes it particularly useful where available installation space is restricted, while retaining compatibility with appropriately sized 150mm ventilation equipment.

For systems where space permits and greater carbon capacity is required, longer U-GO filters are also available. The correct filter should be selected according to the fan, required airflow, available space and overall ventilation design.

Installing the U-GO 150mm Carbon Filter

A typical filtered extraction system draws environmental air through the carbon filter before it reaches the extraction fan. The treated air then continues through the exhaust ductwork.

Fan and filter selection should be considered together. The extraction fan needs sufficient performance to overcome resistance from the filter and duct system while maintaining the required ventilation rate.

  • Support the filter securely and independently.
  • Use 150mm ducting and fittings wherever practical.
  • Match the extraction fan appropriately to the filter.
  • 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 the filter operates, 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 with a longer expected operating life, but actual service life will depend on the conditions in which the filter is used.

Operating hours, airflow, contaminant concentration and environmental conditions can all influence how quickly the activated carbon becomes saturated.

If unwanted odours begin passing through the extraction system despite suitable airflow and secure connections, the carbon may be approaching the end of its effective adsorption capacity.

U-GO 6" 150mm x 300mm Carbon Filter FAQs

What size is this U-GO Carbon Filter?

This compact model has a nominal 150mm / 6" connection and a 300mm filter body.

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 inside the filter. Carbon particle characteristics influence both adsorption performance and resistance to airflow.

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 being used in its filters.

What is the minimum 20% butane adsorption specification?

U-GO specifies a minimum 20% butane adsorption requirement as part of its carbon testing, with material that fails its required standard rejected.

Why does carbon particle size matter?

Particle characteristics affect both adsorption and airflow through the carbon bed. Excessively fine or dusty carbon can create unnecessary restriction.

Does U-GO de-dust its 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 150mm / 6" connection, so matching 150mm ducting and fittings should be used wherever practical.

What is the advantage of the shorter 300mm filter?

The compact 300mm body requires less installation space, making it useful where a longer 150mm carbon filter cannot easily be accommodated.

Can I use this with a 150mm extraction fan?

Yes. It is designed for integration into a 150mm ventilation system, although the fan and filter should also be appropriately matched for the required airflow.

Will the carbon filter reduce extraction airflow?

Yes. Every carbon filter introduces some 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 will the 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.
