The 400g pot is a smart entry point if you're new to odour management or need temporary cover in smaller spaces. Simple to use, safe around people and plants, and it does exactly what it says on the tin.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eOna Gel Pot is a \u003cstrong\u003enatural odour neutraliser\u003c\/strong\u003e formulated from 32 essential oils and plant-derived compounds suspended in a polymer gel. Unlike air fresheners that simply mask smells, ONA works through three active mechanisms — adsorption, absorption, and chemical neutralisation — to permanently eliminate unwanted odours at source. The 400g pot provides 4–6 weeks of continuous odour control depending on room conditions, making it an affordable, low-hassle solution for indoor growing spaces.\u003c\/p\u003e\n\u003ch3\u003eHow it compares\u003c\/h3\u003e\n\u003cp\u003eONA Gel sits in a different space to carbon filters and premium air purification systems.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003evs. Carbon filters:\u003c\/strong\u003e Filters trap odours as air passes through; ONA neutralises them chemically.
