Frequently Asked Questions
General Product Information
What is a plasma air purifier and how does it work?
A plasma air purifier generates plasma consisting of ions and free-moving electrons through electrical discharge. The 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 HEPA-based purifiers use filtration methods requiring regular filter replacements. Plasma air purifiers use ionization technology to actively disinfect air and surfaces, reaching hard-to-access areas without filter bacteria growth issues. Some models can work with existing air purifiers to extend filter lifespan.
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 for optimal air circulation. HVAC-integrated models should be professionally installed within the HVAC unit to distribute ions throughout the building via the ventilation system.
How do I install the plasma air purifier?
Portable units simply plug in and turn on. For HVAC-integrated models, professional installation by certified technicians is recommended to ensure correct and safe operation at optimal performance levels.
Product Performance
What pollutants can the plasma air purifier remove?
Our purifiers effectively remove airborne particles including dust, pollen, and PM2.5 down to 0.001 μm. They eliminate bacteria, viruses, molds, and decompose VOCs such as formaldehyde, benzene, ammonia, acetaldehyde, and acetic acid, while removing unpleasant odors.
How long does it take for the plasma air purifier to start working?
Air quality improvements are noticeable within hours for odor reduction. Comprehensive purification of 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, we offer models suitable for different space sizes. High-capacity purifiers can effectively clean air in large rooms, open-plan offices, or commercial spaces up to 2500 square feet. Choose the appropriate model based on your space requirements for optimal performance.
Safety and Certification
Is the plasma air purifier safe to use around people and pets?
Absolutely. Our products are designed with safety as top priority, tested to comply with strict safety standards. They are certified for zero ozone emissions (UL 2998 standard), ensuring no harmful ozone levels are generated during operation. The ionization technology is completely safe for continuous use around people and animals.
What certifications does the plasma air purifier have?
Our purifiers hold multiple certifications including UL 2998 for zero ozone production, compliance with ASHRAE standards, and certification by the California Air Resources Board (CARB). These certifications demonstrate the quality, safety, and effectiveness of our products.
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 tools. Models with pre-filters can be washed or vacuumed regularly. Refer to your specific model's user manual for detailed maintenance instructions.
How long does the plasma air purifier last?
Average lifespan is 3-5 years depending on usage and environmental conditions. Regular maintenance including cleaning collecting plates or filters and ensuring proper operation can extend device lifespan.
Do I need to replace any parts regularly?
Some models have replaceable components. For example, the HEPA filter in KJ-501TX has a 2-year lifespan with continuous use and is replaceable. Replacement costs are typically 20-25% of machine price, extending usable life by an additional two years.
