Buying guide – how to choose the right ozone generator
Investing in an ozone generator is an effective way to remove strong and embedded odours in homes, vehicles, and other spaces. Unlike air fresheners and traditional odour removers, ozone works by neutralizing the source of the odour at a molecular level. In this buying guide, we will go through what an ozone generator is, how it works, and how to choose the right model.
What is an ozone generator?
An ozone generator is an odor remover that produces ozone (O₃) from oxygen in the air. Ozone is a reactive gas that breaks down odor molecules and organic residues that cause bad odors. Ozone generators are often used for ozone treatment of smoke, pet, basement, and mold odors.
How does an ozone generator work?
Ozone generators supply energy to oxygen molecules (O₂) to form ozone (O₃). As the ozone spreads through the space, it reacts with odor molecules and breaks them down. After the treatment is complete, the ozone naturally breaks down into ordinary oxygen again.
Corona discharge
Corona discharge is the most common and effective method for producing ozone. An electric field splits oxygen molecules, which then form ozone. This method is used in powerful ozone generators for odor removal in homes and commercial premises.
Ozoneair Clean uses corona discharge in combination with ionization (Ionfusion®) for controlled and consistent ozone production.
UV light
Some ozone generators use UV light to create ozone. This method yields lower ozone production and is mainly used in smaller units. UV-based ozone generators are generally less effective at strong odors.
Advantages of odor removal with ozone
Neutralizes odor at the source
Ozone breaks down odor molecules instead of masking them. This makes the method effective against smoke, pet odors, stale odors, and mildew odors.
Treats the entire room
Since ozone is a gas, it reaches textiles, crevices, and hard-to-reach surfaces where odors often linger.
No residual scent
After treatment and proper ventilation, no perfumes or scents remain – just neutral air.
Ozone generator for mold odor and moisture-related odor
Mould problems often manifest as a mouldy smell or a stale, damp odour, especially in cellars, storage rooms and other poorly ventilated areas. An ozone generator for mould odour is used to neutralise odour molecules and microbial residual odours that arise in connection with damp and mould contamination.
It is important to distinguish between cause and odour:
Ozone generators are used as a supplement after moisture problems have been rectified, to remove the lingering odour that can otherwise remain in materials and the air.
Common uses for ozone generators
Ozone generator for basements with musty odor
Basements are particularly susceptible to dampness. Ozone treatment can help remove basement odors and mildew smells that have become embedded in walls, textiles, and furnishings.
Ozone generator for storage and crawl space
In storage rooms and crawl spaces, moisture can create a musty smell over time. Ozone also reaches hard-to-reach surfaces where the smell would otherwise remain.
Ozone generator for water damage
After water damage, moisture-related odors may persist even after remediation. Ozone generators are often used to neutralize this residual odor.
Ozone generator for home
Removes cooking odors, smoke odors, and stale odors in rooms, apartments, and houses.
Car ozone generator
Effective against smoke, moisture, and pet odors in the cabin, seats, and trunk.
Important to consider for mold-related use
- Ozone generator does not replace mold remediation
- The moisture source must always be addressed first
- Ozone is used for odor removal, not building remediation
- Always follow instructions for safe use and ventilation
How do you choose the right ozone generator?
When buying an ozone generator, the most important factor is the size of the space.
- Up to 30 m² – smaller rooms, car, boat
- Up to 60 m² – apartments, larger rooms
- Up to 120 m² – houses, premises, professional use
Also consider lifespan and maintenance. Models with replaceable oxygen plates can be used indefinitely through regular replacement.
How do you safely use an ozone generator?
Step 1: Prepare the space
- Evacuate the room of people, pets, and plants
- Close doors and windows
- Open cupboards and drawers
Step 2: Position the ozone generator
- In the center of the room
- Preferably on a raised surface
Step 3: Set up treatment
- Select the correct surface on the control panel
- Treatment starts automatically after a short delay
Step 4: Aftercare
- Wait at least 2 hours
- Ventilate the room thoroughly before use
