Filter-Free Cordless Air Sanitizer with Dual-Tube DBD Low-Temperature Cold Plasma Technology for Commercial and Residential Spaces

The VDETTE AS04 Low-Temperature Plasma Air Sanitizer utilises dual-tube DBD plasma technology to enhance indoor air quality. Its filter-free design and built-in rechargeable battery support both wired and cordless operation. Place it on a table surface or mount it on a wall. Safe for occupied spaces, it suits residential and a wide range of commercial environments.

• Dual-Tube DBD Plasma System A dual-fan, two-speed structure generates active plasma species to treat indoor air. It works alongside existing filter-based air purification hardware without performance conflict.
• Cordless + Wired Dual Power Supply Equipped with a 6600 mAh lithium-ion battery, delivering more than 8 hours of runtime under Max Mode. QC Type-C charging reaches full charge in approximately 4.5 hours. Freely movable without fixed power socket limitations.
• Dual-Mode Operation with LED Indication
  • Normal Mode (Green LED): 2500 RPM | 30 CFM | ≤32 dBA. Auto power-off after 2 hours. Fit for bedrooms, study rooms and low-traffic zones.
  • Max Mode (Red LED): 3000 RPM | 60 CFM | ≤40 dBA. For high-traffic commercial premises including classrooms, offices and clinics.
• No Filter Consumables Eliminates recurring filter-replacement expense. No chemical agent spraying, no radiation, no high-heat output. Low long-term maintenance burden.
• Low Ozone Emission Lab-measured ozone level <0.02 mg/m³. Actual values vary subject to real-world room conditions.
• Flexible Installation & Customizable Table-top placement or wall mounting, recommended height 1–2 m above ground. Standard finish: Pure White / Space Grey. Custom housing colour available for bulk orders.
• Room Coverage 150–250 m³ effective volume.

The AS04 creates controlled low-temperature plasma, releasing reactive species into surrounding air. These substances interact with volatile organic pollutants, complex indoor odours and lab-tested airborne contaminants to lower their concentration within the space. No chemical mist is released during operation.

1. 1Only utilise the original matching power adapter and Type-C cable.
2. 2Avoid dropping, knocking or unauthorised disassembly; impact can damage plasma and fan assemblies.
3. 3Prevent liquid splashing onto the unit; stay away from corrosive materials and extreme high-temperature surroundings.
4. 4Children and persons with limited sensory capabilities require supervision while the unit is in service.
5. 5Do not place heavy objects atop the device.
