Carbon filters

A carbon filter plays a central role in every grow room. It effectively traps odors and ensures clean, neutral-smelling exhaust air. Especially in enclosed environments such as grow tents or grow boxes, a powerful filter is crucial to reliably transport odors outside without disturbing neighbors or housemates.

Using a Carbon Filter for Grow in combination with a suitable fan and ventilation ducts (see our Ducts category) creates an efficient exhaust system that ensures consistent air circulation, temperature, and humidity control.

Our carbon filters are made from high-quality materials optimized for different applications:

• 💨 Highly active carbon with an optimal pore structure for maximum odor removal.
• 🔧 Durable housings made of metal or robust plastic for long-lasting use.
• 🌿 Filter fleece for pre-cleaning the air, reducing dust and larger particles.
• 🌡️ Temperature- and humidity-resistant design for grow rooms, industrial, or kitchen use.

Brands like Prima Klima and Carbon Active rely on certified quality, ensuring high filter performance throughout the filter’s lifespan.

When choosing between a Can Inline Filter and a standard carbon filter, it depends on the application. Inline models, like those from Can Inline Filter, are integrated directly into the ventilation duct, saving space – ideal for small grow boxes or tight installations.

Standard carbon filters – such as the proven models from Rhino Pro or Prima Klima – feature a flange connection and are installed at the beginning of the exhaust line. Their larger carbon surface often provides longer lifespan and stronger odor absorption.

A combination of both types can be useful for maximum odor control. For example, install a standard carbon filter at the fan and a Can Inline Filter at the end of the exhaust system as a secondary safeguard.

Our carbon filters are specially designed for grow boxes, tents, and professional grow rooms. They effectively prevent odor nuisance and support climate control:

• 🌱 Indoor grows: Clean exhaust, consistent air circulation, and plant protection.
• 🍀 Grow boxes: Efficient odor filtration for small to medium tents.
• 🏢 Industry and workshops: Capture odors, dust, and pollutants.
• 🏠 Kitchen and home: Exhaust filtration for range hoods and ventilation systems.

Combined with high-quality ducts and fans, you create a complete, powerful exhaust system.

Our carbon filters cover a wide range of airflow capacities: from 160 m³/h to 4500 m³/h. Choose the right variant based on grow room size and required air volume. Common flange connections include:

• 📏 100 mm, 125 mm, 160 mm
• 📏 200 mm, 250 mm, 315 mm
• 📏 350 mm

For home grow boxes, 100–160 mm is usually sufficient, while larger rooms or professional setups require 200–350 mm. Brands like Prima Klima, Carbon Active, and Rhino Pro offer all common sizes.

The lifespan of a carbon filter for grow depends heavily on the environment:

• 💨 Strong odors or smoke in the room significantly shorten its lifespan.
• 🏙️ Air containing dust or pollutants – e.g., urban environments – puts extra load on the filter.
• 🌱 Clean grow rooms with low airflow prolong filter life considerably.
• 🔧 Reducing airflow or using the filter only when needed exponentially increases lifespan.

Regularly checking the exhaust and adjusting the fan when necessary helps maximize filter efficiency.

• 🌡️ Slight odor from the exhaust? – Reduce airflow, throttle fan, optimize filter contact time.
• 🧴 Perfume test: Spray a scent on the filter fleece and check the exhaust – adjusts airflow perfectly.
• ⚙️ Black particles inside the tube? – Manufacturing residue, no impact on performance, just remove.
• 💧 Overpressure or high humidity: Reduce intake, increase exhaust, optionally dry carbon with a heater fan.
• 🔄 Refill carbon yourself: possible, but ensure exact centering and vibration; Prima Klima provides original carbon.
• 🖤 Black spots on white filter fleece: carbon dust, no effect on function; some manufacturers pre-dye.

An optimal carbon filter for grow reaches its full potential only when combined with suitable components:

• 💨 Suitable fans for the desired airflow.
• 🌀 Flexible ducts or ducts in matching diameters (100–350 mm) for efficient air guidance.
• 🔧 Inline filters for space-saving, additional odor control.
• 🌿 Combine with grow box filters for maximum efficiency and odor removal.

This creates a fully integrated system that optimally regulates airflow, temperature, and humidity while reliably trapping odors.

Our Carbon Filter Grow Box solutions from Prima Klima, Carbon Active, and Can Inline Filter provide everything needed for clean, odor-free exhaust in grow areas. Different sizes, flange connections, and airflow capacities allow individual customization, while combining with suitable fans and ducts ensures maximum efficiency.

Benefit from durable materials, easy installation, and professional advice – for optimal climate, clean air, and maximum odor control in your grow room.
