Odor Control Systems

Why This Collection Helps Growers

• Rapid, reliable odor mitigation at the source
• Cleaner intake air to reduce disease pressure and equipment fouling
• Longer carbon bed life with pre-filtration to protect against clogging
• Stable negative pressure and consistent CFM for predictable results
• Options for exhaust scrubbing, recirculating scrub, and final-stage polishing

Best Uses

• Grow tents and home grow rooms needing quiet, discreet exhaust
  
• Commercial rooms and greenhouses requiring strict air quality and compliance
  
• Facilities near neighbors where odor neutrality is essential
  
• Propagation-to-finish environments seeking particulate and pathogen reduction

Types of Odor Control Solutions

• Carbon Filters & Fan/Filter Combos: Activated carbon captures odors, gases, and VOCs as exhaust air passes through; pair with properly sized inline fans for efficient scrubbing.
• Pre-Filters: Wraps or sleeves that trap dust and debris before they reach the carbon bed—maintain CFM and extend filter life.
• Intake, Dust & HEPA Filters: Scrub incoming air to block bacteria, mold, pollen, insects, and fine particulates.
• Air Boxes (Inline Carbon Housings): Inline enclosures to filter dust, foreign particulates, spores, and odors in duct runs.
• Gels & Sprays: Odor neutralizers for localized areas, entries, or ancillary spaces.
• Ozone, Oxidizers & UV Purifiers: Advanced treatment that neutralizes odors and organic compounds in air streams (use according to manufacturer safety guidance).

How to Size & Set Up

1. Calculate room volume (L×W×H) and target 30–60 air changes/hour to determine required CFM.
2. Match the filter’s rated CFM to your fan’s operating CFM after accounting for ducting, bends, and silencers.
3. Maintain slight negative pressure so odors don’t escape.
4. Use pre-filters on carbon to maximize lifespan; replace as they load.
5. For intake air, add dust/HEPA filters sized to fan draw to protect the space and equipment.

Frequently Asked Questions

How do I stop my grow room from smelling?

Use a carbon filter paired with a properly sized inline duct fan to scrub exhaust air and maintain slight negative pressure. Add pre-filters to extend carbon life and consider intake/HEPA filters to keep particulates out. For extra polish, use gels/sprays or a UV/ozone stage where appropriate.

What is an odor control system?

An odor control system combines filtration (carbon, HEPA, air boxes) and, optionally, chemical/UV treatments with ventilation to capture and neutralize odors, VOCs, and airborne contaminants before air leaves your space.

What is a standard and effective odor control for your grow room?

The most common, effective setup is a matched fan and carbon filter sized to your room’s CFM, installed in a way that maintains negative pressure and includes a pre-filter. Many growers also filter intake air to reduce dust and spores.

How to ventilate a grow room?

Determine target CFM from room volume and desired air changes/hour, then install an inline fan with a carbon filter on the exhaust. Use smooth duct runs with minimal bends, seal connections, and provide filtered intake air to balance flow.

Can a carbon filter remove smell?

Yes. Activated carbon adsorbs odor molecules and VOCs as air passes through. Correct sizing, a clean pre-filter, and adequate contact time (CFM) are key to consistent odor removal.
