🌬 Neutralises Odours Instead of Masking Them
ONA Gel works differently from standard air fresheners.
Instead of simply covering smells with perfume, ONA technology:

This makes ONA Gel highly effective in environments where strong odours are generated constantly such as flowering grow rooms and drying spaces.
