ONA Gel Odour Neutraliser – Long-Lasting Odour Eliminator for Home, Pets & Grow Rooms

The ONA Gel Odour Neutraliser is a powerful, long-lasting odour control solution designed to neutralise unwanted smells in homes, workplaces, indoor gardens, grow rooms and other enclosed spaces. Unlike conventional air fresheners that simply cover unpleasant smells with fragrance, ONA Gel uses a specialist blend of essential oils and odour-neutralising ingredients to help tackle airborne odours at their source.

Available in a choice of 400g, 732g, 3.8kg and 20kg containers, ONA Gel provides flexible odour management for everything from small rooms to larger commercial and horticultural environments.

Choose from four distinctive fragrances: Fresh Linen, Polar Crystal, ONA PRO and Tropics. Whether you're dealing with persistent household smells, pet odours, stale air or unwanted odours around an indoor growing area, ONA Gel offers a convenient way to maintain a fresher environment.

Simply open the container and position it in an appropriate location to allow the gel's active ingredients to disperse naturally into the surrounding air. Larger containers can also be used with compatible ONA dispensing equipment for increased air circulation and fragrance distribution.

Key Features & Benefits

Effective odour neutralisation: Designed to neutralise unwanted airborne odours rather than simply mask them.
Long-lasting gel formula: Gradually releases odour-neutralising ingredients through natural evaporation.
Essential oil-based formulation: Contains a blend of essential oils and odour-neutralising ingredients.
Four container sizes: Available in 400g, 732g, 3.8kg and 20kg options.
Four fragrance choices: Fresh Linen, Polar Crystal, PRO and Tropics.
Simple application: Open the lid and place the container in an appropriate location.
No electricity required: Works through passive evaporation when used without a fan dispenser.
Suitable for different environments: Ideal for homes, offices, workshops, pet areas and horticultural spaces.
Compatible with ONA dispensers: Suitable containers can be paired with compatible ONA fan-based distribution systems.
Flexible odour control: Suitable for occasional odour problems and ongoing background odour management.

How Does ONA Gel Work?

ONA Gel uses a specially developed combination of odour-neutralising ingredients suspended within a gel-based formula.

Once the container is opened, the active ingredients are gradually released into the surrounding air through natural evaporation. These ingredients interact with unwanted airborne odours, helping reduce their presence rather than relying solely on stronger fragrance to disguise them.

The gel formulation is designed to provide controlled dispersion, allowing the product to work gradually over time.

The rate of evaporation depends on factors such as room temperature, airflow, humidity, exposed gel surface area and the intensity of the odour problem.

Available ONA Gel Sizes

ONA Gel is available in four convenient sizes to suit different room sizes, application methods and odour control requirements.

ONA Gel 400g Jar

The 400g ONA Gel Jar is a compact option for smaller spaces and localised odour problems. Its convenient size makes it easy to position on a stable surface in a suitable location.

Ideal for small rooms, cupboards, utility spaces, workshops and other areas where targeted odour control is required.

ONA Gel 732g Jar

The 732g ONA Gel Jar offers a larger quantity of gel for general-purpose odour management around the home, office or growing environment.

It can be used as a standalone open container and is a practical option for ongoing odour control.

ONA Gel 3.8kg Pail

The 3.8kg ONA Gel Pail is designed for larger areas or applications requiring a greater quantity of odour-neutralising gel.

It can be used for passive odour control or with compatible ONA dispensing equipment where increased distribution is required.

ONA Gel 20kg Pail

The 20kg ONA Gel Pail is a bulk option for commercial environments, larger workspaces and high-volume odour management.

It is also suitable for refilling smaller compatible containers or use with appropriate ONA dispensing systems.

Choose Your ONA Gel Fragrance

The ONA Gel range is available in four fragrance options, allowing you to choose a scent that suits your surroundings.

ONA Gel Fresh Linen

Fresh Linen offers a clean, laundry-inspired fragrance, making it a popular choice for homes, offices and general indoor odour control.

ONA Gel Polar Crystal

Polar Crystal provides a crisp, fresh fragrance profile suited to spaces where a cool, clean-smelling atmosphere is preferred.

ONA Gel PRO

ONA PRO features the distinctive original-style ONA fragrance profile and is a versatile choice for general-purpose odour neutralisation.

ONA Gel Tropics

Tropics provides a tropical-inspired fragrance option for users who prefer a warmer, fruitier scent.

Please Note: Fragrance availability may vary by container size. Select your preferred size and fragrance from the available product options.

ONA Gel for Grow Rooms & Indoor Gardens

ONA Gel Odour Neutraliser is a popular option for managing unwanted smells around indoor gardening areas, grow rooms and horticultural workspaces.

It can be positioned in an appropriate adjoining space, extraction area or other suitable location to help neutralise unwanted airborne odours.

For best results in a grow room, use ONA Gel as part of a wider odour control strategy that may include adequate ventilation and an appropriately sized activated carbon filter.

Important: Avoid positioning strongly fragranced odour-neutralising products directly alongside sensitive flowers, harvested botanical materials or exposed produce, where fragrance transfer could be undesirable.

ONA Gel for Household & Pet Odours

ONA Gel is also suitable for general household odour control, helping reduce unwanted smells in everyday living and working environments.

Typical Applications

Household odour control
Pet-related smells
Cooking and kitchen odours
Stale or musty-smelling rooms
Offices and commercial premises
Workshops and utility areas
Indoor gardening and horticultural workspaces
Storage areas and suitable enclosed spaces
General background odour management

For persistent odours, identify and address the underlying source wherever possible. ONA Gel is intended to help manage airborne smells rather than replace cleaning, hygiene or ventilation.

Use ONA Gel with Compatible Fan Dispensers

Although ONA Gel works through natural evaporation, compatible fan dispensers can help increase the distribution of odour-neutralising ingredients in larger spaces.

The ONA Breeze Fan is designed for compatible ONA Gel containers, while the ONA Cyclone is intended for larger-scale dispensing applications.

Fan-assisted distribution may be useful where natural evaporation alone does not provide sufficient coverage.

Please Note: Dispensers are sold separately. Always confirm container compatibility before purchasing.

How to Use ONA Gel

Select the appropriate size: Choose a container suitable for your intended application and odour control requirements.
Prepare the container: Shake as directed by the manufacturer before opening.
Remove the lid: Open the container and remove any protective liner or seal.
Choose a suitable position: Place the container upright on a stable surface in an area where unwanted odours are present.
Allow natural evaporation: The odour-neutralising ingredients will gradually disperse into the surrounding air.
Adjust distribution: For larger areas, consider a compatible ONA fan dispenser where appropriate.
Monitor the gel: Check the remaining quantity periodically and replace or refill when required.
Store correctly: Reseal the container when not in use and follow the manufacturer's storage instructions.
