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. When released into air, 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 filter air through physical barriers that trap particles, requiring regular filter replacements. Plasma air purifiers use ionization technology to actively disinfect air and surfaces, reaching hard-to-access areas without filter-related bacteria growth issues. Some models can work alongside existing purifiers and extend disposable filter lifespans.
Installation and Placement
Where should I place the plasma air purifier?
For portable models, place in a central room location away from walls and large furniture to ensure optimal air circulation. For HVAC-integrated models, professional installation within the HVAC unit distributes ions throughout the building via the ventilation system.
Product Performance
What pollutants can the plasma air purifier remove?
Our purifiers effectively remove airborne particles (dust, pollen, PM2.5 down to 0.001μm), eliminate bacteria, viruses, and molds, decompose VOCs including formaldehyde, benzene, and ammonia, and remove unpleasant odors.
Is the plasma air purifier safe to use around people and pets?
Absolutely. All products are UL 2998 certified for zero ozone emissions, meeting strict safety standards. The ionization technology is completely safe for continuous use around people and animals.
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. 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 environment. Regular maintenance including cleaning collecting plates or filters helps extend device longevity.
