Ona Block Polar Cristal 170 g
ONA Block Polar Crystal 170 g delivers continuous odor neutralization through a solid wax block infused with 32 essential oils. Engineered for indoor grow rooms, grow tents and cultivation spaces where strong plant odors require reliable elimination. Equally effective in bathrooms, basements and garages with persistent moisture-related smells. ONA technology works through three mechanisms: absorption, adsorption and molecular pairing — neutralizing odors permanently rather than masking them. The Polar Crystal variant adds a clean, crisp scent profile. One 170-gram block provides up to four weeks of coverage depending on airflow conditions. Non-toxic and safe around people, pets and plants.
ONA Block Polar Crystal 170 g — crisp odor neutralization for grow rooms and living spaces
The ONA Block Polar Crystal delivers reliable, set-and-forget odor control in a compact 170-gram wax block. Inside, 32 essential oils work through three scientifically validated mechanisms — absorption, adsorption and molecular pairing — to permanently bind and eliminate odor molecules. Unlike conventional air fresheners that overlay fragrance on top of bad smells, ONA destroys the odor compounds at a molecular level.
Performance in indoor cultivation setups
For growers running sealed or semi-sealed environments, odor management is non-negotiable. The ONA Block Polar Crystal serves as a secondary defense layer alongside your carbon filter. Position the block near your tent exhaust, in the adjacent corridor or by the room entrance. The essential oils capture volatile organic compounds that escape your primary filtration. One block covers approximately a 3x3 grow tent footprint for up to four weeks.
Residential and utility applications
Beyond cultivation, the Polar Crystal variant handles common household odor challenges effectively:
- Bathrooms and basements: eliminates mildew and damp odors without aerosol chemicals or plug-in devices.
- Garages and utility rooms: neutralizes fuel, oil and rubber smells in poorly ventilated enclosed spaces.
Remove the lid completely for maximum output or drill holes for regulated release and extended lifespan. Fully non-toxic and environmentally safe.

How long does one ONA Block Polar Crystal 170 g last?
One ONA Block Polar Crystal provides approximately four weeks of continuous odor neutralization under standard conditions. High airflow and elevated temperatures accelerate evaporation and reduce lifespan. Drilling holes in the lid rather than removing it completely can extend effective duration significantly while maintaining adequate odor control.
Can ONA Block Polar Crystal be used alongside a carbon filter in a grow tent?
ONA Block works as an effective complement to carbon filtration. Position the block outside the grow tent — near the exhaust output or in the surrounding room — to catch residual odors that bypass the filter. Avoid placing the block inside the tent among plants, as prolonged direct exposure to concentrated essential oils may influence the terpene profile of your crop.
