BIODOR Control CNB Odour Eliminator – 33g, 200g & 800g | Neutral & Eucalyptus

BIODOR Control CNB Odour Eliminator is a powerful, highly concentrated solid-gel odour neutraliser designed to help tackle persistent unwanted smells rather than simply mask them with stronger fragrances. Manufactured by Biopulcher, BIODOR CNB gradually releases specialist odour-neutralising ingredients into the surrounding air, providing convenient, long-lasting odour management.

Available in 33g, 200g and 800g sizes, with a choice of Neutral or Eucalyptus, BIODOR Control CNB offers flexible odour control for everything from smaller rooms and storage spaces to larger commercial environments and suitable ventilation systems.

Its concentrated formula is designed to interact with unwanted airborne odours, making it a practical alternative to conventional air fresheners that rely primarily on perfume to disguise unpleasant smells.

Whether you need a compact odour neutraliser for a small space or a larger gel format for more demanding applications, the BIODOR CNB range provides a convenient solution without the need for regular manual spraying.

Key Features & Benefits

Highly concentrated formula: Specialist solid-gel odour neutraliser designed to help reduce persistent unwanted smells.
Three sizes available: Choose 33g, 200g or 800g to suit your requirements.
Two fragrance options: Neutral for minimal residual fragrance or Eucalyptus for a fresh-smelling finish.
Long-lasting odour management: Gradually releases active ingredients over time.
Odour neutralisation: Designed to help tackle airborne odour molecules rather than simply disguise them.
Compact 33g format: Convenient for smaller spaces and localised odour control.
Versatile 200g format: Suitable for larger applications with appropriate airflow.
High-capacity 800g format: Provides a larger quantity of concentrated gel for demanding odour management requirements.
No manual spraying: The gel works through gradual evaporation.
Flexible positioning: Can be used in suitable ventilated locations according to the manufacturer's instructions.
Domestic and commercial applications: Suitable for homes, workplaces, storage areas and horticultural environments.

How Does BIODOR Control CNB Work?

BIODOR Control CNB uses a concentrated solid-gel formulation containing specialist odour-neutralising agents and inhibitors.

When exposed to air, the gel gradually releases active ingredients into the surrounding environment. These ingredients are designed to interact with unwanted airborne odour molecules, helping reduce unpleasant smells.

Unlike conventional room sprays that require repeated manual application, BIODOR CNB provides ongoing odour management as its ingredients evaporate.

Air movement can help distribute the active ingredients throughout the surrounding area, making correct positioning particularly important for larger applications.

The rate of evaporation and overall performance depend on several factors, including temperature, airflow, odour intensity, ventilation and the amount of gel exposed to the air.

Important: BIODOR Control CNB is an odour neutraliser, not an activated carbon filter, extraction fan or particulate air purifier. It does not remove dust, smoke particles or harmful airborne contaminants.

BIODOR Control CNB Sizes – 33g, 200g & 800g

The BIODOR CNB range is available in three sizes, allowing you to choose the appropriate quantity of odour-neutralising gel for your environment.

BIODOR Control CNB 33g – Compact Odour Neutraliser

The 33g BIODOR Control CNB is the smallest option in the range, offering concentrated odour management in a compact, easy-to-position format.

Ideal for smaller rooms, utility spaces, storage areas and suitable localised applications, the 33g version provides a convenient way to manage unwanted smells without additional powered equipment.

The manufacturer quotes coverage of up to 50m², depending on the intensity of the odour and surrounding conditions.

The 33g gel is supplied within a protective breathable cloth, allowing the active ingredients to evaporate while reducing direct contact with the gel.

Important: Keep the protective cloth around the 33g gel in place during use.

BIODOR Control CNB 200g – Medium to Large Area Odour Control

The 200g BIODOR Control CNB provides a larger quantity of concentrated gel for environments where more demanding odour management is required.

Suitable for commercial workspaces, storage areas, workshops and compatible ventilation applications, the 200g version is designed to distribute its active ingredients through suitable airflow.

The manufacturer quotes coverage of up to 250m² when used with appropriate forced airflow. Actual coverage may be lower depending on odour intensity, room layout and operating conditions.

For effective distribution, position the 200g gel securely using a suitable compatible holder or mounting arrangement, following the manufacturer's instructions.

BIODOR Control CNB 800g – High-Capacity Odour Eliminator

The 800g BIODOR Control CNB is the largest option available in this listing, providing a substantial quantity of concentrated odour-neutralising gel for more demanding applications.

Designed for customers who require a larger gel format, the 800g option is particularly suited to suitable commercial, industrial, storage and horticultural environments where ongoing odour management is important.

Its larger gel capacity provides more odour-neutralising material than the 33g and 200g versions, making it a practical choice where a high-capacity format is preferred.

For best results, position the 800g product according to the manufacturer's instructions, ensuring appropriate airflow and secure placement.

Please Note: Effective coverage and product lifespan depend on the installation method, temperature, airflow and odour intensity. A specific maximum coverage figure for the 800g version has not been confirmed.

Neutral or Eucalyptus – Choose Your Fragrance

BIODOR Control CNB Neutral

The Neutral formulation is designed to help tackle unwanted odours while leaving minimal residual fragrance.

It is an excellent choice for customers who prefer discreet odour management without introducing a noticeable additional scent into the surrounding environment.

BIODOR Control CNB Eucalyptus

The Eucalyptus formulation combines the product's concentrated odour-neutralising technology with a fresh eucalyptus-inspired fragrance.

Ideal for customers who prefer a subtle, clean-smelling finish alongside effective odour management.

Available combinations: 33g Neutral, 33g Eucalyptus, 200g Neutral, 200g Eucalyptus, 800g Neutral and 800g Eucalyptus.

Long-Lasting Solid-Gel Odour Control

One of the main benefits of BIODOR Control CNB is its gradual-release solid-gel formulation.

The manufacturer provides an estimated effective lifespan of approximately 1–2 months for the established smaller formats under suitable conditions.

Actual duration varies according to the size of the gel, exposed surface area, ambient temperature, airflow and odour intensity. The 800g format should not be assumed to have the same operating lifespan without checking the manufacturer's guidance.

Warmer temperatures and increased airflow can accelerate evaporation, potentially improving distribution while increasing gel consumption.

Ideal Applications for BIODOR Control CNB

The BIODOR Control CNB range provides versatile odour management for a variety of suitable environments.

Homes and utility rooms
Garages and workshops
Warehouses and storage facilities
Commercial premises
Industrial workspaces
Suitable vehicle interiors
Indoor gardening facilities
Hydroponic workspaces
Horticultural equipment areas
Suitable ventilation and extraction systems
General persistent odour management

BIODOR Control CNB for Grow Rooms & Hydroponics

Managing unwanted smells can be an important part of maintaining a pleasant indoor gardening or hydroponic environment.

BIODOR Control CNB provides supplementary odour management in suitable adjoining rooms, equipment areas and ventilation-related applications.

The 33g option is convenient for smaller areas, while the 200g and 800g options provide larger quantities of concentrated gel for applications requiring greater capacity.

For persistent airborne odours in enclosed growing environments, properly sized extraction equipment and activated carbon filtration should remain the primary methods of odour control.

Important: Avoid positioning the gel where its released ingredients could come into contact with plants, flowers, exposed produce or sensitive growing materials.

How to Use BIODOR Control CNB

Select your size: Choose 33g, 200g or 800g according to your odour management requirements.
Choose your fragrance: Select Neutral or Eucalyptus.
Read the instructions: Follow the manufacturer's guidance for your selected product size.
Choose a suitable location: Position the product near the source of unwanted smells in an appropriately ventilated area.
Prepare the gel: Open or expose the product only as directed by the manufacturer.
Position securely: Ensure the product cannot fall, spill or obstruct ventilation equipment.
Allow gradual release: The active ingredients will disperse into the surrounding air over time.
Monitor performance: Check effectiveness periodically and replace the gel when required.

33g Usage Note: Leave the protective breathable cloth in place.

200g & 800g Usage Note: Follow the installation instructions specific to the selected size, particularly when using the product with powered airflow or ventilation equipment.
