We stock two brands of 4 inch carbon filters; Prima Klima filters for those on a budget and the market leading Rhino Pro filters that offer excellent lifespan and odour control.
Rhino Pro Filters
In our opinion Rhino Pro filters are the best on the market. Constructed from lightweight aluminium and packed full of premium activated carbon, they are lightweight, easy-to-handle, and do an unparalleled job when it comes to odour control.
Rhino Pro filters use Australian-mined Tiwest RC124 activated carbon which is the purest activated carbon on the market and considered by many to be the best in the world for odour neutralising purposes. This carbon provides superb filtration for two years or more and is extremely effective in both high and low humidity environments.
The 4 inch carbon filter from Rhino Pro is suitable for use with both low-power and high-power fans. It is important that you match the air flow rates of your fans and carbon filters as failing to do so will result in less effective odour control and can dramatically reduce the lifespan of both components.

Air Volume: 350 m3/hr
Prima Klima Filter
Our budget 4 inch carbon filter comes from German manufacturer Prima Klima and is only designed for use with low-powered fans. Even though these are labelled as ‘budget;’ Prima Klima filters are made to a very high standard and use a high-grade activated carbon derived from pit coal.
Although there is a slight difference in odour control ability, the main difference between Prima Klima budget filters and our Rhino Pro filters is longevity. The Prima Klima filter should be changed around every nine to twelve months, whereas Rhino Pro filters will easily last two years or more before needing replacement.

Airflow: 360 m3/hr
Both out budget and Rhino Pro filters offer fantastic absorption and odour control. We’d always recommend buying the Rhino Pro filters if you can afford the initial outlay as they work out cheaper in the long run, but both filters are quality products.
All carbon filters work in a similar way utilising the super adsorbent and high surface area properties of activated carbon. This type of carbon has been oxidised to give it a massive surface area.
To put things in perspective, just one gram of activated carbon has a surface area greater than 500 meters squared and a small five gram piece has roughly the same surface area as a football pitch – so it’s pretty impressive stuff.
It’s these properties along with fantastic adsorption that make carbon filters so effective at odour control, as any odours in the air that flow through the filter are effectively trapped by the activated carbon.How do I set-up this carbon filter?
