What Is Ozone Cleaning?

Ozone (O₃) is a gas made of three oxygen atoms. It’s a powerful oxidizer, meaning it can break down the cell walls of bacteria and fungi, and damage the outer layers of viruses, essentially inactivating them. Once the treatment is done, ozone naturally turns back into oxygen (O₂), so it doesn’t leave any chemical residue behind. (MDPI)

A professional ozone cleaning session works like this:

The room is sealed, a certified ozone generator is placed inside, and both the ozone concentration and exposure time are carefully controlled. No people or pets may be inside during the treatment. Afterward, the room is fully ventilated until it’s completely safe again. (MDPI)

​

What Does the Science Say?
 

As Corporate Member of the British Institute for Cleaning Science (BICSc), BrightClean Chiang Mai relies on research-backed cleaning methods. Here’s what studies tell us about the effectiveness and safety of ozone.
 

1. Ozone vs. Bacteria

A 2024 study found that even low levels of ozone (around 5 ppm) were effective against several clinically relevant and often multi-resistant bacteria. When the correct exposure time was used, researchers observed strong reductions in bacterial growth. (Frontiers)

Other hospital-based studies confirm that ozone significantly reduces bacterial load on surfaces and materials. (PMC)
 

2. Ozone vs. Viruses, Including SARS-CoV-2

Multiple reviews and laboratory studies show that ozone can inactivate viruses in both surface contamination and aerosols:
 

• A 2022 scoping review concluded that ozone can disable viruses on surfaces when concentration, humidity, and exposure time are properly controlled. (SciELO)

• A 2023 critical review on SARS-CoV-2 found that ozone reduces the virus on different surfaces, depending on exposure time and environment. (Taylor & Francis Online)

• Studies using live SARS-CoV-2 showed a sharp drop in viral activity and viral RNA after ozone treatment. (PMC)
   

There’s also research on disinfecting surgical masks: ozone reduced pathogens while keeping the mask usable, provided the process was professionally controlled. (BioMed Central)
 

The important takeaway:
Ozone works well when used correctly and safely.
That’s where BrightClean Chiang Mai excels.

Where Ozone Cleaning Helps Most: Homes, Airbnb, and Offices

​

1. Homes in Chiang Mai

Our climate can cause:

• persistent moisture or mold odors;

• lingering pet smells in furniture and fabrics;

• cooking, smoke, or paint smells that never quite go away;

• high bacterial levels in busy living areas.

Ozone helps by:

• reaching hidden spots where regular cleaning can’t;

• neutralizing odors at the source instead of covering them up;

• freshening the entire indoor environment.

2. Airbnb & Short-Stay Rentals

Your Airbnb reviews depend on how clean and fresh your place feels.
Ozone cleaning is especially useful:

• after guests who smoke or cook strong-smelling foods;

• when you allow pets;

• after large groups or illness;

• when humidity causes musty smells.

Benefits for Airbnb hosts:

• Faster turnover: the apartment can often be rented again the same day.

• Better reviews: guests notice a crisp, neutral, “new” smell.

• A marketing advantage: you can highlight that you use professional ozone disinfection (without medical claims).

3. Offices and Commercial Spaces

In offices, clinics, studios, or coworking areas:

• many people share the same air;

• air-conditioning spreads odors and microorganisms;

• shared spaces like meeting rooms and pantries accumulate bacteria.

Ozone helps by:

• removing deep-set odors;

• reducing microbes in the air and on surfaces;

• creating a healthier work environment.

The Benefits You’ll Notice Immediately
 

When BrightClean Chiang Mai performs ozone cleaning, you get:
 

1. True odor removal

Ozone eliminates the source of the smell—whether it’s bacteria, mold, smoke, or cooking odors.
 

2. Broad antimicrobial action

Studies show ozone can inactivate various bacteria and viruses when used properly. (Frontiers)
 

3. Deep reach

Because it’s a gas, ozone spreads everywhere: cracks, vents, cushions, curtains, and even dust layers.
 

4. No chemical residues

Ozone naturally reverts to oxygen afterward. No detergents or residues remain. (MDPI)
 

5. Quick treatment time

Most sessions take only a few hours, including ventilation.
 

6. Fully controlled and professional

We use precise measurements and strict safety protocols to ensure your space is completely safe after treatment.

Safety First: Honest About Risks

​

Ozone is effective, but it must be used responsibly. Organizations like the U.S. EPA and European health agencies warn that direct exposure to ozone can irritate the lungs and worsen asthma. (epa.gov)
 

That’s why BrightClean Chiang Mai follows strict safety rules:

• No people or pets in the room during treatment.

• No access until the entire contact time has passed.

• The space is ventilated until ozone levels are fully safe.

• We never use ozone in permanently occupied rooms or as a “gadget” purifier.
   

Health authorities also warn that small consumer ozone devices used in lived-in rooms often don’t work well—and may still pose risks. (epa.gov)
 

In short:
Ozone is powerful, professional equipment, not a household toy.

How We Perform Ozone Cleaning at BrightClean Chiang Mai
 

Here’s what a typical treatment looks like:
 

1. Intake & inspection

We assess your space, the odor or hygiene issues, and your goals.
 

2. Tailored plan

We calculate the exact ozone dose and exposure time.
 

3. Room preparation

We seal the space, check windows and doors, and protect equipment.
 

4. Ozone treatment

The generator runs its cycle. No one may enter.
 

5. Ventilation & safety check

We ventilate and verify that ozone levels have dropped to a safe level.
 

6. Completion & adviceWe give you a brief report and tips to prevent future odor or moisture issues.

Is Ozone Cleaning Right for You?

​

You should consider ozone cleaning if you:
 

• have recurring odors in your Airbnb;

• move into a home or office with an “old” or musty smell;

• struggle with moisture or mold odor;

• want a hygienic reset after illness;

• want chemical-free deep-cleaning as an addition to regular cleaning.

Final Thoughts: Cleaning, Ventilation, and Ozone Work Best Together
 

Ozone is not a replacement for traditional cleaning, you still need to remove dust, dirt, and visible mold first. But ozone is a powerful additional step, especially for:
 

• hard-to-reach spots,

• stubborn odors,

• and reducing microbial load.

BrightClean Chiang Mai combines:
 

• professional manual cleaning,

• advice on ventilation and humidity control,

• and controlled ozone treatments.

The result is a cleaner, fresher, healthier living or working environment, something especially valuable
in Northern Thailand’s climate.
