Why Ozone Machines Aren’t Enough for Permanent Odour Removal

The Truth About Ozone Machines vs. BioSweep® Technology

Ozone machines are often marketed as a fast, powerful solution for odour problems in homes, vehicles, and commercial buildings. While ozone can temporarily reduce smells in the air, it is not a reliable or permanent solution for deep, structural odour contamination.

For professional-grade, permanent results, BioSweep UK provides advanced odour removal, decontamination services, and mould remediation that go far beyond the limitations of ozone.

The Fundamental Problem with Ozone

Ozone (O₃) is an unstable gas that reacts quickly with airborne particles. While this may reduce odours briefly, ozone has three major limitations:

1. It mainly treats the air, not the structure

Ozone struggles to penetrate deeply into porous materials such as:

• Plaster and dry lining

• Timber and joists

• Carpets and soft furnishings

• Insulation and ceiling voids

This means the true source of the odour often remains untouched.

2. Results are usually temporary

Once ozone dissipates, embedded odour molecules can reactivate, especially with changes in humidity or temperature.

3. Ozone poses health and material risks

Ozone is a lung irritant. At effective concentrations required for odour neutralisation, spaces must be fully evacuated. Prolonged exposure can also:

• Degrade rubber and plastics

• Damage fabrics

• Accelerate corrosion

Ozone may make a room smell “cleaner” for a short time, but it does not deliver verified, lasting odour removal.

Why Odours Come Back After Ozone Treatment

Persistent odours are not just floating in the air — they are absorbed into the building fabric itself. Smoke, mould, flood-related contamination, pet odours, decomposition and long-term neglect all drive odour molecules deep into structural materials.

Because ozone does not consistently penetrate these materials, the odour source remains active. This is why many property owners experience:

• Odour 'bounce-back' weeks later

• Strong smells returning during warm or humid weather

• Ongoing complaints in rental and commercial properties

BioSweep: Permanent Odour Removal at a Molecular Level

BioSweep UK delivers true source neutralisation using a verified five-stage gas-phase oxidation process, which includes:

• Germicidal UV light

• Plasma energy

• Hydroxyl radicals

• HEPA filtration

• Oxyradical production

This creates a 'treatment cloud' that travels through the entire building envelope, including hidden voids, soft furnishings, and structural elements.

Unlike ozone, BioSweep:

• Neutralises odour molecules at their molecular structure

• Does not rely on masking agents

• Leaves no chemical residue

Delivers permanent odour removal, not temporary suppression

A Safer, Greener Alternative

Unlike fogging or chemical masking agents, BioSweep® leaves behind no residues or toxic by-products. It’s a clean, environmentally responsible process that achieves total odour and contaminant removal without repeat treatments or secondary damage.

Independent UKAS-Accredited Verification

One of the most important differences between BioSweep and ozone is measurable proof.

BioSweep treatments can be verified using pre- and post-treatment air and surface sampling, analysed by an independent UKAS-accredited laboratory. This provides documented evidence for:

• Insurers

• Landlord

• Letting agents

• Environmental health officers

• Commercial compliance audits

Ozone treatments rarely, if ever, provide this level of independent verification.

Ozone and Mould: An Incomplete Solution

Ozone is sometimes used for mould-related odours, but it does not constitute professional mould remediation. It may reduce airborne smell temporarily, but:

• It does not address moisture sources

• It does not penetrate deeply into affected materials

• It provides no long-term microbial suppression

BioSweep, by contrast, plays a highly effective role in professional mould remediation strategies. It is important to be precise:

• BioSweep suppresses mould and decontaminates the environment; it does not claim to eliminate mould spores entirely.

• When combined with moisture control and appropriate building repairs, BioSweep delivers a robust, insurable mould remediation outcome.

Safe, Residue-Free and Material Compatible

Unlike ozone and many chemical fogging systems, BioSweep:

• Produces no hazardous residue

• Does not bleach or damage surfaces

• Safe for electronics, textiles, timber, plastics and finishes

• Leaves no lingering chemical odour

• Compatible with homes, care environments, vehicles and commercial premises

This makes it suitable for:

• Residential properties

• Rental portfolios

• Hotels and leisure facilities

• Healthcare environments

• Insurance reinstatement projects

When Ozone Fails, BioSweep Succeeds

BioSweep is regularly specified following:

• Fire damage

• Flooding and escape-of-water incidents

• Long-term mould contamination

• Severe pet odours

• Tobacco and smoke odours

• Decomposition and biological contamination

  
  

Because BioSweep treats the source within the structure, it dramatically reduces:

• Strip-out costs

• Replacement of soft furnishings

• Delays to reoccupation

• Insurance claim cycle times

Ozone vs BioSweep - Frequently Asked Questions

Is ozone the same as BioSweep?

No. Ozone is a single oxidising gas, whereas BioSweep uses a five-stage gas-phase oxidation process that combines UV light, plasma energy, hydroxyl radicals, HEPA filtration and oxyradical production. This allows BioSweep to penetrate materials and neutralise contamination at a molecular level without relying on hazardous ozone concentrations.

Why does ozone sometimes seem to work at first?

Ozone can temporarily reduce airborne odours, which may create the impression of success. However, because it does not consistently penetrate building materials, odours often return once the ozone dissipates, particularly during warm or humid conditions.

Is ozone dangerous to use indoors?

At effective concentrations, ozone is a lung irritant and can be harmful if inhaled. This is why properties must be fully vacated during treatment. Ozone can also degrade rubber, plastics and fabrics over time.

Can ozone permanently remove smoke, fire or flood odours?

In most cases, no. Ozone mainly treats the air, not the structural materials where odours are absorbed. This means odours resulting from fire, flooding or long-term contamination often reactivate after ozone treatment.

Why is BioSweep considered a permanent solution?

BioSweep neutralises odour molecules at their molecular structure, rather than masking or temporarily oxidising them. Its multi-stage oxidation process penetrates plaster, timber, textiles, insulation and voids, permanently destroying the source of the odour.

Does BioSweep leave any chemical residue?

No. BioSweep is residue-free. Unlike fogging or spraying, it does not coat surfaces with chemicals or perfumes. Once treatment is complete and ventilation has taken place, there are no lingering residues.

Is BioSweep safe for pets, fabrics and electronics?

Yes. BioSweep is material-safe and non-toxic. It is suitable for use around soft furnishings, electronic equipment, timber, plastics and decorative finishes when applied by trained technicians.

Can ozone or BioSweep treat mould?

Ozone may reduce airborne mould odours temporarily but is not a mould remediation solution.

BioSweep plays a powerful role in professional mould remediation by suppressing mould and decontaminating the environment. It does not claim to eliminate mould spores entirely, but it significantly reduces the active microbial load when combined with moisture control and repairs.

Is BioSweep verified by independent testing?

Yes. BioSweep treatments can be supported with pre- and post-treatment sampling analysed by an independent UKAS-accredited laboratories using testing methods, providing documented proof of air and surface improvement. This level of verification is not typically available with ozone.

Why do insurers and professionals avoid ozone?

Because ozone results are difficult to verify, potentially hazardous, and often temporary. Insurers and restoration professionals require measurable, permanent, and auditable outcomes, which is why BioSweep is widely specified for insurance reinstatement works.

When should I choose BioSweep instead of ozone?

You should choose BioSweep if:

• You need permanent odour removal

• The odour is embedded in the structure

• The property is part of an insurance claim

• You require UKAS-verified results

• There are health, safety or reoccupation concerns

Can BioSweep replace fogging and ozone entirely?

In most professional restoration and decontamination scenarios, yes. BioSweep provides deeper, safer, verified and permanent results compared to both ozone and chemical fogging.
