| 1. Test Conditions |
- Room size: 13.4 m²
- Environment: Closed room, no external airflow
- Device: Air+430
- Fan speed: Level 5
- Duration: ~2.5 hours of continuous operation
|
| 2. Particle Count Results |
- A significant reduction was observed across all particle size ranges.
- 0.5 µm particles:
- Initial value: ~2,702,560 particles/m³
- Final value: ~120,000 particles/m³
- Reduction: ~95–96%
- Similar strong reductions recorded for 1.0 µm, 2.0 µm, 5.0 µm, and 10 µm classes, stabilizing after the first hour of operation.
- Conclusion: The Air+430 demonstrates excellent particle removal efficiency, consistent with performance levels observed in controlled environments (approx. ISO 7–8 for airborne particulate).

| 3. Microbiological Sampling Results |
- Tests were carried out using TSA (bacteria, 30°C) and SDA (yeasts and molds) plates.
- TSA (bacteria at 30°C):
- Initial mean: 192 CFU/m³
- Final mean: 205.6 CFU/m³
- → Stable, with variations within expected statistical noise (initial bacterial load already very low).
- SDA (yeasts & molds):
- Initial mean: 93.6 CFU/m³
- Final mean: 16.8 CFU/m³
- Reduction: ~82%
- Conclusion: The Air+430 shows a strong reduction of fungal/mold load and maintains low bacterial levels in an already clean environment.
|
| 4. Overall Technical Assessment |
- The data confirms high purification efficiency, both in particulate removal and in reduction of fungal microorganisms.
- Performance progression is smooth, consistent, and stable over time.
- The results can be used as a first Italy-based technical validation, pending further certified testing with SDS Convalide.
- Please review the attached report for the full dataset and graphs.
- Let me know if you need the raw Excel file or a formatted technical sheet for internal documentation.
- Best regards, Alex
