Shopping malls are places of mass gatherings with intense visitor flow. Thousands of people touch the same surfaces daily: escalators, handrails, elevator buttons, door handles. Ozonation maintains air quality, eliminates odors and provides infection prevention.
Regular ozone treatment during off-hours disinfects all surfaces, including hard-to-reach areas and technical zones. The gas penetrates all rooms, ensuring comprehensive treatment of the entire facility.
Treatment zones in shopping malls
- Shopping galleries and atriums — main visitor gathering areas
- Escalators and elevators — contact surfaces with maximum load
- Food courts — sources of odors and food contamination
- Restrooms — critical hygiene zones
- Storage and technical rooms — often ignored during cleaning
- Ventilation systems — distribute air throughout the mall
- Parking lots — accumulate exhaust fumes and odors
Odor problem in malls
Shopping malls combine many odor sources: food courts, restrooms, perfume stores, storage areas. Ozone effectively neutralizes all these odors, not masking them, but destroying the molecules of odorous substances.
| Zone | Odor source | Solution |
|---|---|---|
| Food court | Food preparation, grease, spices | Night ozonation + duct ozone generators |
| Restrooms | Organic substances | Continuous low-concentration ozonation |
| Atrium | Odor mixing, stuffiness | Ventilation integration |
| Parking | Exhaust fumes | Duct ozone generators in exhaust |
Ozonation organization options
Night treatment
Mobile ozone generators treat the mall after closing. Maximum effectiveness.
Ventilation integration
Duct ozone generators in HVAC system. Continuous air quality maintenance.
Zonal treatment
Wall-mounted ozone generators in problem zones: restrooms, food court, parking.
Combined approach
Combination of all methods for maximum effect
Treatment mode
Night disinfection
After mall closing, mobile ozone generators are started. Treatment 2-4 hours depending on area. By opening, ozone completely decomposes.
Food court
Daily treatment after cafes close. Elimination of cooking odors, disinfection of tables and chairs.
Restrooms
Low-power ozone generators work continuously at safe concentration or turn on automatically during breaks.
Ventilation
Duct ozone generators supply ozone to air ducts, ensuring supply air disinfection.
Equipment calculation
| Zone | Area | Capacity | Mode |
|---|---|---|---|
| Shopping gallery | 1000-5000 m² | 50-200 g/h | Night treatment |
| Food court | 500-1500 m² | 20-60 g/h | Daily after closing |
| Restroom | 20-50 m² | 1-2 g/h | Continuous or cycles |
| Storage | 100-300 m² | 5-15 g/h | 2-3 times per week |
| Parking | 5000-20000 m² | 100-500 g/h | Ventilation integration |
Effectiveness against pathogens
| Pathogen | Time (20 mg/m³) | Effectiveness |
|---|---|---|
| Coronaviruses | 10-15 min | 99.9% |
| Influenza viruses | 5-10 min | 99.9% |
| Norovirus | 15-20 min | 99.9% |
| Staphylococcus aureus | 10-15 min | 99.99% |
| E. coli | 5-10 min | 99.99% |
| Mold | 30-40 min | 99% |

Safety for visitors
With proper organization, ozonation is absolutely safe for visitors and shopping mall staff.
- Main treatment — at night when the mall is closed
- Ventilation integration — at safe concentrations
- Restrooms — automatic shutdown when visitors enter
- Concentration sensors — real-time ozone level monitoring
- By opening, ozone completely decomposes into oxygen
