Ona Mist (Apple Crumble) 170g - Instant Odour Neutralising Spray
Best for: growers who want a quick, on-demand odour neutralising spray for moments when passive gel or filtration isn't enough, or for smaller spaces that don't need a full extraction setup.
Our thoughts
This isn't a replacement for proper carbon filtration in a full grow room - it's the quick-fix spray for doorways, small spaces, or that one moment you need odour dealt with right now. It genuinely neutralises rather than just masking, which matters if you've ever sprayed a strong air freshener over a grow smell and made it worse.
Ona Mist (Apple Crumble) is a 170g spray-format odour neutraliser built on Ona's blend of natural essential oils, combined with water, propylene glycol and sodium stearate, with no toxic ingredients or harsh chemicals in the formulation. Rather than simply masking odours with a stronger scent, the active blend works to neutralise the odour molecules themselves, leaving a mild apple crumble fragrance behind rather than the smell it's dealing with.
It can be used two ways: fitted into an Ona Mist Dispenser for automated, timed release, or simply pressed by hand as a manual spray whenever you need it. With normal airflow, one unit refreshes a room of around 16m², and a single 170g unit typically lasts up to 30 days depending on temperature and airflow conditions. It's made in Canada, in line with the rest of the Ona odour-control range.
How it compares
Ona Mist sits at the fast, low-effort end of odour control, compared to passive gels and active filtration systems that need more setup.
- Against a full Ona gel tub with or without the Cyclone Fan, this is a much smaller-scale, faster-acting product for spot treatment rather than continuous whole-room coverage
- Compared to standard aerosol air fresheners, Ona's essential oil blend is designed to neutralise odour molecules rather than just cover the smell with a stronger scent
- Against carbon filtration on an extraction line, this works in the room itself rather than filtering air as it leaves, making the two approaches complementary rather than competing
If you need something small, fast and genuinely odour-neutralising rather than a room-scale system, this fills that gap well.
Usage guidance
Manual use
Simply press the top down to release a spray whenever odour needs dealing with immediately - useful by doorways, in smaller tents, or ahead of visitors.
Dispenser use
Fit into a compatible Ona Mist Dispenser for automated, scheduled release throughout the day without needing to spray manually each time.
Coverage and timing
Expect one unit to cover a room of around 16m² with normal airflow, lasting up to 30 days depending on how warm the room runs and how much air movement there is - replace sooner in warmer, higher-airflow conditions.

Who this is for
- Growers wanting a fast, on-demand spray for spot odour control
- Anyone with a smaller space who doesn't need a full gel tub or extraction system
- Growers who want a genuine odour neutraliser rather than a masking air freshener
Best suited to smaller spaces or as a quick top-up alongside an existing extraction or filtration setup.
Our take
A small, straightforward product that does one job honestly - neutralise odour on demand without resorting to harsh chemicals or a strong masking scent. It's not a substitute for proper filtration in a serious grow room, but that's not what it's for.
One we sell a lot of for new growers who just need a quick, reliable fix for everyday odour moments.
