ONA Gel: Popular, Practical and Powerful

ONA Gel is a complex mix of essential odour neutralising oils, suspended in a polymer gel. The essential oils are organically sourced from plants throughout the world, producing a natural, non toxic odour neutraliser.

Open the ONA Gel lid to disperse the ONA particles into the air and neutralise any airborne odours. This results in a pleasant smell being left in place of the odours occupying the room.

The odour neutralising agents molecules disperse through natural evaporation, ensuring every drop of product is fully optimised. This regulates the lifetime of the product and ensures you do not use more than is necessary.

ONA Gel Provides True Neutralisation

Unlike air fresheners, this is not a masking agent but a neutralisation agent. The result is a completely fresh smelling atmosphere that will remain as long as there are no more odour particles entering the space. If the source of odour persists then the ONA Gel use should continue.

There are 3 types of mechanisms involved in the neutralisation of the odour molecules:

science of ona adsorption

science of ona absorption


ONA Gel is Non Toxic and Environmentally Friendly

ONA Gel is industrial strength, and safe for home or business use. This means it is safe to use around people, pets and plants. It is non toxic, environmentally friendly and organic.

Don’t be fooled by imitations that are appearing in the market. This is the undisputed and original odour neutralising agent, serving the hydroponics industry since 1995.


ONA Gel is available in Pro, Fresh Linen, Polar Crystal Apple Crumble and Tropics scents.


Available in 428g Jars (6 per case), 732g Jars (6 per case), 3.27Kg Jars (4 per case), 3.8Kg Pails (4 per case) and 20Kg Pails.

Instructions for Use

Open the lid and leave the ONA Gel to naturally disperse for as long as the odour is present. We recommend occasionally shaking the jar to agitate the contents.

To regulate the lifetime of the ONA Gel, pour a portion of the gel into a suitable container. Once the ONA Gel has been used, top up with more product. This will ensure you are not using more product than is necessary.

Utilise the ONA  Breeze fan to treat larger areas or stronger odours. Attach the ONA Breeze fan to the top of your 732g or 3.27Kg jar. This will increase the dispersion of ONA, but please note this will all increase consumption rate.

In extremely large areas use the 20Kg ONA Gel with the ONA Cyclone fan. This heavy duty fan has 5 speed settings to provide odour control for up to 5,000 square feet.

How to Use ONA Gel Efficiently

ONA Gel is the most popular product in the range and is practical for all odour problems. To get the most out of your gel follow these tips on using your ONA Gel most effectively.

Remove the lid form the ONA Gel and leave it around the infected area to naturally evaporate and disperse through the air.

To neutralise a larger area, increase the rate of dispersion. Our excellent fan-type dispensers will greatly increase the distribution of ONA. The Breeze fan will fit the 732g and 3.27Kg jars.
