Mammoth RC 48 Carbon Filter — Professional Odour Control at Half the Weight
Best for: Growers who need reliable odour elimination without the weight penalty of heavier filters
Our thoughts
This is proper kit at sensible pricing. Mammoth filters use the same quality Australian carbon as premium brands but weigh half as much, which means your tent frame doesn't suffer. Thick carbon bed, light construction, cyclone airflow design — it's the kind of thoughtful engineering you notice when you're hanging it and three months in when you're still getting clean air out.
The Mammoth Carbon Filter is an inline carbon filter designed to scrub odours and VOCs out of your grow room air before it leaves the space. Filled with premium RC 48 virgin activated carbon — high-pore Australian-mined material with just 13% ash content — it traps and neutralises smells rather than masking them. The open mesh exterior and cyclone base maximise airflow, meaning maximum air passes through for absorption. At half the weight of competitor filters, it hangs easily without straining tent frames or ceilings.
How it compares
- Premium brands like Phresh cost significantly more for comparable carbon; Mammoth delivers the same odour-scrubbing performance at mid-market pricing
- Budget alternatives use thinner carbon beds (30mm); Mammoth runs 38–50mm depending on model, meaning longer lifespan between replacements
- Lightweight aluminium construction beats heavy steel casing found on many competitors — easier to install, less tent sag
- Cyclone design and pre-filter sleeve (included) extend filter life and improve efficiency versus basic designs
Usage guidance
Installation
Unwrap the filter, fit the pre-filter sleeve (keeps larger particles out of the carbon), then attach directly to your inline fan via a fast clamp or short length of ducting and clips. Hang as close to the top of your grow room as possible using the provided hanging straps. Always match your filter's airflow rating to your fan capacity — mismatched sizing causes odour leaks.
Best practice
Position inside your tent at the intake point of the fan to create negative pressure. This ensures all air leaving the space passes through the carbon. Replace the pre-filter sleeve regularly (every few months depending on dust load) and the main carbon bed every 12–18 months with standard filters, or 6–12 months with Mammoth Lite variants.
Suitable for
Any indoor growing setup — grow tents, dedicated rooms, sheds, or greenhouses. Works equally well in hydroponic systems, soil grows, or mixed setups. Also handles household VOCs from paint, cooking, or other sources.

Who this is for
- New growers setting up their first extraction system who want proven reliability without overspending
- Experienced growers replacing filters and tired of heavy units straining tent infrastructure
- Anyone running multiple grow spaces where filter costs compound — good time to buy while clearance stock lasts
- Growers prioritising odour control in shared or domestic spaces
- Setup builders looking for a filter that pairs reliably with inline fans and standard ducting
Our take
This is a carbon filter that does exactly what it should — traps odours, lasts longer than budget alternatives, and doesn't punish your tent with unnecessary weight. RC 48 carbon is quality stuff, the bed thickness is proper, and the engineering is straightforward.
If you're building an extraction system or replacing a worn-out filter, worth picking up. Does the job reliably, cycle after cycle.
