Professional Odour Control Built on APEX 4-8 Virgin Carbon
Phresh Professional Carbon Filters scrub extracted air clean of dust, particulates, organic compounds and odours, using APEX 4-8 virgin activated carbon. Built to professional grade for serious hobby and commercial grow rooms, they deliver total air-stream filtration with far less weight than typical steel-bodied filters.
Key Benefits
- APEX 4-8 virgin activated carbon, batch tested so each grain absorbs at least 20% butane
- Lightweight build: aluminium tops and bases, and granular carbon that weighs half as much as pelletised carbon
- Sealed and labelled at manufacture, bagged and boxed straight off the line to protect carbon life
- Long service life, built to last around twice as long as many other brands
- Built for grow rooms and greenhouses, from serious hobby setups to commercial rooms
How long should a carbon filter really last?
There is no fixed lifespan for activated carbon — it depends on how much airborne impurity the bed absorbs, plus airflow rate and climate. Phresh's APEX 4-8 virgin carbon is batch tested, with each grain required to absorb at least 20% butane, so a filter matched to its fan's airflow gets the most from every grain.
How to Use
- Fit the filter inline before your extraction fan so air is drawn through the carbon bed before exhausting.
- Match your fan's airflow to the filter's rated capacity for the best odour control and longest carbon life.
- Support the filter properly rather than letting it hang from ducting alone.
- Fit one of the two supplied pre-filters and keep it clean to extend carbon life.

Questions & answers
Which size Phresh filter do I need?
Match the filter's rating to your fan: from 340 m3/h on the 100mm x 300mm up to 3,910 m3/h on the 315mm x 1200mm. Running within that rating gives the best odour control and longest carbon life.
How long does the carbon last?
There's no fixed lifespan; it depends on how much the carbon absorbs, the airflow and your climate. As a guide, a typical user gets around two years.
Is a pre-filter included?
Yes. Keep it clean, and machine-wash or replace it at about six months to extend carbon life.
Where does it go in the system?
Fit it before the extractor fan so air is drawn through the carbon bed before it's exhausted. Support the filter properly rather than hanging it from ducting alone.
What carbon does it use?
RC-48 Australian activated carbon, in a filter with aluminium tops and bases that weighs around half as much as comparable filters, so it's easier to hang.
