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, 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 fragrance being left in place of the odours occupying the room. The odour neutralising 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 true odour neutraliser. 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. Don’t be fooled by imitations that are appearing in the market. This is the undisputed and original odour neutraliser, serving the hydroponics industry since 1995.

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, 3.27Kg or 3.8Kg 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.
