Mars Hydro 4" Refillable Carbon Filter – Premium Air Filter for Grow Tent Ventilation & Odor Control

The Mars Hydro 4-Inch Refillable Carbon Filter offers powerful, professional odor control for stable and efficient grow tent ventilation. This high-quality air filter is filled with 100% Australian virgin charcoal, known for its exceptionally high absorption capacity and long lifespan.

Specifically developed for use with 4-inch inline exhaust fans, this carbon filter is ideal for grow tents, grow rooms, hydroponic systems, and other enclosed indoor growing environments where clean, odor-free air is essential.

Thanks to its refillable design, reversible flange, and included pre-filter, this model combines maximum flexibility, durability, and long-lasting performance without compromising airflow or efficiency.

Professional Odor Control for Indoor Growing

During the flowering phase, strong odors can arise that, without adequate filtering, escape through ventilation systems. The Mars Hydro 4” carbon filter neutralizes:

• Flowering and plant odors
• Humid air and musty odors
• Air pollutants in enclosed grow tents
• Unwanted emissions via extraction

The activated carbon effectively captures odor particles before they are exhausted outside via ventilation.

Refillable & Durable Design

Unlike standard disposable filters, this model features a refillable carbon filter system, ensuring:

• Lower maintenance costs
  
• Longer lifespan
  
• Sustainable solution for long-term indoor cultivation
  
• Consistent filtration performance

This makes the filter particularly suitable for serious hobby growers and professional indoor setups.

Reversible Flange for Maximum Flexibility

The reversible 4-inch flange allows for flexible installation within various ventilation configurations. This also extends the filter's lifespan by allowing it to be used evenly.

Fully compatible with:

• 4-inch inline fans
• 100mm exhaust systems
• Standard ducting in grow tents

Includes Pre-Filter

The included pre-filter protects the carbon material from dust, pollen, and larger particles. This keeps the activated carbon effective longer and maintains optimal airflow through the filter.

Applications

This 4-inch carbon filter is ideal for:

• Grow tents of small to medium size
• Hydroponic and DWC systems
• Indoor cultivation of vegetables, herbs, and flowering plants
• Closed ventilation systems
• Professional odor control in indoor grow rooms
