Portable Mini Air Purifier (Industrial Design Prototype)

1. Project Overview
This OEM/ODM project demonstrates the industrial design and structural prototype development of a compact desktop air purifier. The reference design combines a rounded-cube enclosure, top turbine-intake structure, removable filter compartment and magnetic cover within a 98 × 98 × 160 mm body. Functional prototypes were used to evaluate the airflow path, filter replacement structure and assembly experience before further engineering development.

2. Industrial Design & Enclosure Development
• Rounded-Cube Form: The reference design uses softened corners and a compact vertical profile suitable for desktop and bedside placement.
• Compact Enclosure Architecture: Internal components are arranged within the 98 × 98 × 160 mm housing to balance portability with the required filtration and airflow structure.
• Magnetic Cover Design: A removable magnetic cover provides access to the internal filter compartment while maintaining a clean exterior appearance.
• Removable Filter Compartment: The filter housing is developed for straightforward removal and replacement during routine maintenance.
• Exterior Surface Development: Product proportions, openings and enclosure details are refined through 3D modeling before physical prototype production.

3. Airflow & Filtration Structure
• Turbine-Intake Structure: The reference project incorporates a top intake architecture developed around the internal fan and airflow path.
• H13 HEPA Filter: The demonstrated configuration uses an H13 HEPA filter as the primary filtration element.
• Airflow Path Development: Internal ducting and component placement are coordinated to guide air through the filtration system within the compact enclosure.
• 35 m³/h Reference CADR: The reference prototype specifies a Clean Air Delivery Rate of 35 m³/h under the corresponding test configuration.
• ≤10 m² Reference Coverage: The demonstrated configuration is intended for small personal spaces of up to approximately 10 m².

4. Portable Operation & Prototype Validation
• <38 dB Reference Noise: The demonstrated configuration specifies an operating noise level below 38 dB under the corresponding test conditions.
• 8-Hour Reference Battery Life: The prototype specifies up to 8 hours of operation according to its reference battery and operating configuration.
• USB-C Charging: Provides a standard charging interface for the portable product concept.
• Functional Prototype Testing: Physical prototypes are used to evaluate airflow, component arrangement and filter removal before further development.
• Assembly Evaluation: Prototype validation helps assess magnetic-cover operation, filter access and overall assembly relationships.

5. OEM/ODM Development Capability
• Portable Air-Care Product Development: Suitable for brands developing compact air purifiers and related personal air-care devices.
• Project-Based Customization: Product dimensions, exterior form, filtration structure, airflow architecture and charging configuration can be developed according to individual project requirements.
• Airflow & Structure Integration: Supports coordinated development of enclosure geometry, fan structure, filter compartment and internal airflow path.
• Design-to-Prototype Support: Covers industrial design, 3D structural development, appearance rendering and functional prototype validation according to project scope.
• Production-Oriented Development: Validated design and structural data can provide the basis for subsequent engineering, tooling and manufacturing preparation.
