It is not a masking agent. It is nontoxic, environmentally friendly and safe to use around people pets and plants. ONA is a true odour neutraliser, directly bonding with the odour molecules to render them null and inert – safely and completely.

ONA gel is a complex mix of essential oils, suspended in a polymer gel. The essential oils are organically derived from plants throughout the world, nontoxic and environmentally friendly, when the ONA gel is exposed to atmosphere the ONA particles are released into the air and neutralise any airborne odours, it comes into contact with. The ONA Gel odour neutralising agents are released in a controlled manner so that every drop of this excellent product is fully optimised.

ONA Gel Provides True Neutralisation

Once the ONA Gel is exposed to atmosphere the ONA particles disperse through natural evaporation and any odourous molecules they come into contact with will be neutralised. Unlike air fresheners, this is not a masking agent but a neutralisation agent.

ONA Gel is Non Toxic and Environmentally Friendly

ONA Gel is industrial strength, yet safe for home or business use, and can be used around people, pets and plants.

Nontoxic, 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.
