Advanced Plasma Technology
Kangbeijing Company introduced plasma-related technologies from Germany in 2015 and collaborated with scientific research institutions including Zhejiang University and Lanzhou University to achieve localization and output of imported technologies.
Our plasma generator utilizes Dielectric Barrier Discharge (DBD) technology, the mainstream plasma generation technology in plasma medicine. This advanced system generates low-temperature atmospheric plasma with high stability, high activity, and large area coverage.
In 2020, Kangbeijing"s plasma products obtained "Disinfection Product" certification and began establishing cooperation with medical institutions. By 2023, the company expanded its plasma production line to form a complete product system from medical to commercial and civil use.
Certifications & Quality Assurance
Kangbeijing holds multiple certifications including ISO14001, ISO9001, CE, and CTI. The company was rated as a "Science and Technology-based Small and Medium-sized Enterprise" in Zhejiang Province in 2024.
Third-party testing confirms our products rapidly and efficiently inactivate and remove bacteria, viruses, and harmful gases such as TVOC, with performance parameters exceeding relevant international standards.
Intellectual Property: 4 invention patents, 1 design patent, and 18 utility model patents.
Frequently Asked Questions
General Product Information
What is a plasma air purifier and how does it work?
Our plasma air purifier generates plasma through electrical discharge, creating a mixture of ions and free-moving electrons. These unstable ions initiate chemical reactions that break down harmful substances including bacteria, virus cells, and volatile organic compounds (VOCs), effectively cleaning the air by eliminating pathogens and pollutants.
How is a plasma air purifier different from traditional air purifiers?
Traditional purifiers rely on filtration methods requiring regular filter replacements. Our plasma technology actively disinfects air and surfaces without filters, reaching hard-to-access areas and eliminating bacteria growth concerns associated with filter-based systems.
Installation and Placement
Where should I place the plasma air purifier?
For portable models, place in a central location away from walls and large furniture to ensure optimal air circulation. Our certified technicians can assist with professional installation for integrated HVAC system models.
How do I install the plasma air purifier?
Portable units simply plug in and turn on. For complex installations, our certified technicians provide professional installation services to ensure optimal performance and safety.
Product Performance
What pollutants can the plasma air purifier remove?
Our purifiers effectively eliminate airborne particles (dust, pollen, PM2.5 down to 0.001μm), kill bacteria, viruses, and molds, and decompose harmful VOCs including formaldehyde, benzene, ammonia, and acetic acid, while removing unpleasant odors.
How long does it take for the plasma air purifier to start working?
Noticeable odor reduction occurs within hours, while comprehensive air purification including fine particles and pathogens typically requires 1-2 days of continuous use, depending on initial pollution levels and room size.
Does the plasma air purifier work in large spaces?
Yes, our high-capacity models effectively clean air in large rooms, open-plan offices, and commercial spaces. The KJ-A9 is designed for areas up to 240m².
Safety and Certification
Is the plasma air purifier safe to use around people and pets?
Absolutely. Our products are UL 2998 certified for zero ozone emissions, ensuring no harmful ozone levels are generated. The ionization technology is completely safe for continuous use around people and animals.
What certifications does the plasma air purifier have?
Our purifiers hold UL 2998 certification for zero ozone production, comply with ASHRAE standards, and are certified by the California Air Resources Board (CARB), ensuring quality, safety, and effectiveness.
Maintenance and Longevity
How do I clean and maintain the plasma air purifier?
For models with collecting plates, remove and clean plates using non-abrasive methods. Pre-filters can be washed or vacuumed regularly. Refer to the user manual for specific maintenance instructions.
How long does the plasma air purifier last?
Average lifespan is 3-5 years depending on usage and environment. Regular maintenance and proper operation help extend device longevity.
Do I need to replace any parts regularly?
Some models have replaceable components. Ion-generating components may require replacement after 2 years of continuous use, typically costing 20-25% of the machine price.
