Carbon filter pack: the complete solution for odor-free ventilation
A carbon filter pack is the essential setup for managing both air renewal and odor elimination in your grow space. These kits include an extractor, an activated carbon filter, and connection accessories for a ready-to-use installation. No more separate purchases and incompatibilities: everything is sized to work together efficiently.
Why choose a carbon filter pack
The main advantage is guaranteed compatibility between all components. When you choose the
TT MAX 125mm 2-Speed Extractor Pack - ProActiv Carbon Filter 125mm/250m3/h, you can be sure that the 250 m³/h extractor perfectly matches the ProActiv filter with the same flow rate. No oversizing that wastes energy, no undersizing that lets odors through.The activated carbon in these filters effectively captures odor molecules thanks to its microporous structure. A quality filter can process up to 400 m³/h of air laden with volatile organic compounds. 2-speed extractors like the one in the TT MAX pack allow you to adjust the flow rate as needed: reduced speed at night to limit noise, maximum speed during periods of high plant activity.For installation, these packs generally include clamps, connection sleeves, and sometimes even ducting. For example, the
Prima Klima 125mm Extractor Pack - 360m3/h - 1 Speed + ProActiv Carbon Filter Ø125mm - 400 m3/h offers a slightly higher flow rate for spaces requiring more intense air renewal.
How to choose your carbon filter pack
The number one criterion is the volume of your grow space. To calculate the necessary flow rate, multiply the length × width × height of your tent, then multiply by 60 to get air changes per minute. A 1.2 × 1.2 × 2m tent (2.88 m³) therefore requires approximately 173 m³/h minimum. Packs with 250-400 m³/h are perfectly suited for spaces from 1 to 4 m².The connection diameter must match your tent's openings: 125mm for most tents from 60 to 150cm per side, 150mm for larger installations. Also check the filter length: a ProActiv 125mm measures approximately 25cm, so you need to allow for vertical space.For noise level, 2-speed extractors are more versatile. A TT MAX at speed 1 produces about 35 dB, acceptable even at night. Prima Klima 1-speed models are generally quieter but less flexible. Also consider the lifespan of the carbon: a ProActiv filter lasts 12 to 18 months depending on the intensity of use.
Frequently Asked Questions
How to choose a carbon filter pack compatible with my current air extractor?
If you already have an extractor, check its flow rate in m³/h and its outlet diameter. The carbon filter must have a flow rate equal to or slightly higher than your extractor to avoid air restriction. For example, for a 200 m³/h extractor in 125mm, choose a ProActiv 250 m³/h filter of the same diameter. Be careful with overly powerful extractors that can suck in carbon particles if the filter is not suitable.
Where should I place the carbon filter in my grow tent with the ventilation pack?
The filter is always placed on the intake side, never on the exhaust. Ideal position: suspended high in the tent, connected to the extractor by a short duct. Hot, odor-laden air naturally rises towards the filter. Leave 20-30cm of space around the filter for uniform aspiration. The extractor can be placed outside the tent to reduce noise and heat inside.
How long does the carbon filter in a pack last and when should it be changed?
A ProActiv filter generally lasts 12 to 18 months in continuous use, depending on the intensity of odors to be treated. The first signs of wear: odors starting to pass through despite the extractor running, or a noticeable loss of flow. A saturated filter creates excessive resistance that strains the extractor and increases its consumption. Note the date of commissioning to anticipate replacement.
Is this carbon filter pack sufficient for a 1m² or 2m² tent?
For a 1m² tent (100×100×200cm = 2m³), a 250 m³/h pack is largely sufficient and provides 125 air changes per hour. For 2m² (120×120×200cm = 2.88m³), 250-400 m³/h packs are perfectly suitable. Oversizing is not a problem: it allows the extractor to run at reduced speed for less noise, while maintaining a margin for temperature or humidity peaks.
How to maintain and clean the carbon filter in the pack after each cycle?
Activated carbon cannot be cleaned: it is a consumable that needs to be replaced. However, you can gently vacuum dust from the external surface of the filter with a low-power vacuum cleaner. Avoid water, which would destroy the carbon. Between cycles, store the filter in a dry and airy place. A wet filter loses its effectiveness and can develop mold. Pre-filtration with a sock or fine fabric extends its lifespan by retaining large particles.
