Ultra-Low Noise Air Purifier Designed for Bedrooms and Quiet Environments
The Ultra-Low Noise Air Purifier is engineered specifically for residential bedrooms, medical facilities, and other quiet-sensitive environments where sound levels must remain below 25 dB(A). Utilizing a high-efficiency HEPA filter and advanced silent motor technology, it removes 99.97% of airborne particles including dust, pollen, pet dander, and fine particulate matter (PM2.5) without compromising on performance or acoustics. Designed with industrial-grade durability and certified for compliance across major export markets, this unit ensures consistent air quality in regulated spaces. Built for global B2B procurement, each unit undergoes rigorous testing to meet IEC 60335 safety standards, FCC Part 15 Class B for electromagnetic compatibility, and CE marking under the Low Voltage Directive. Certifications include RoHS compliance and REACH registration, ensuring legal market access in Europe, North America, and key Asia-Pacific regions. This makes it a reliable choice for distributors, healthcare providers, and facility managers requiring regulatory-ready equipment.

Buying Tips for Importers
- Verify that the product’s CE marking includes the applicable harmonized standard (e.g., EN 60335-2-69) for air purifiers
- Confirm the RoHS declaration covers all component materials, especially PCBs and solder alloys used in internal electronics
- Avoid suppliers offering 'FCC-compliant' without specifying Class B emission limits—critical for residential use
- Ensure the manufacturer provides an official REACH Substance of Very High Concern (SVHC) declaration for traceability
- Request test reports from accredited labs (e.g., TÜV, SGS) covering both acoustic output and electromagnetic emissions
