Rather than simply covering smells with fragrance, ONA technology:

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

The fragrance remains fresh and clean while continuously working to eliminate unwanted airborne smells.
