Is the "Air Purifier" Bought at a High Price Just a Psychological Comfort?

A hot search has attracted widespread attention. Several celebrities issued urgent apologies and promised "full refunds" — it turned out that the popular health product "Eucy" , which claimed to be "100% imported from Australia", was exposed by CCTV for fabricating its overseas origin and brand background. The product was actually OEM-produced in China, and its overseas registration address was even an abandoned auto repair shop.

This is not an isolated case. In recent years, "fake foreign brands" have frequently collapsed — from imported health products to smart home appliances, from beauty and skin care to maternal and infant products, similar stories have repeated themselves.

Consumers pay the price of imported products but get goods that do not match the description. What is more worrying is that the exaggerated publicity of some products may even directly affect health and safety.

In the field of air purification and disinfection, similar phenomena of technological "watering down" cannot be ignored either.

The "Plasma" Air Purifier You Use May Be Just an Electrostatic Generator

Opening the product detail pages on some e-commerce platforms, professional terms such as "plasma purification", "ion sterilization" and "plasma technology" can be seen everywhere. These seemingly "high-tech" terms attract consumers who are increasingly concerned about respiratory health.

Especially families with the elderly, children and members with allergic constitutions are more willing to pay for concepts such as "active disinfection" and "thorough purification".

But few people know that among the air purification products on the market that claim to use "plasma technology", the internal structure of many brands is actually just a high-voltage electrostatic grid, which does not have the real plasma generation function at all.

This is what the industry often calls "needle tip discharge technology" — a low-level technology that can only generate weak corona discharge in a small local area at the needle tip.

It sounds similar, but the actual use effect is worlds apart.

What’s the Difference Between Real DBD Plasma and "Needle Tip Discharge"?

Simply put, it’s like the difference between a flashlight and an operating lamp: one can only illuminate a small area in front of you, while the other can evenly cover the entire operating table.

The difference between the two is also reflected in a key indicator — safety.

Due to the wide distribution of electron energy and limited control precision, needle tip discharge technology is prone to generate a large amount of ozone (O₃). Excessive concentration will irritate the human respiratory tract. In contrast, DBD plasma technology can strictly control the ozone generation within the safe threshold of 0.1mg/m³ specified by the national standard by precisely adjusting the voltage frequency and dielectric material, truly realizing safe operation with "human-machine coexistence".

Why Do We Need to Be More Serious About "Invisible Things"?

When health products fail, we can see it — they hit the hot search, celebrities apologize, and platforms conduct interviews. But when you buy an air purification and disinfection device home, it is invisible and intangible. Is it really effective? Is it a "fake plasma"? Consumers can hardly judge.

Moreover, air purification and disinfection equipment is not a one-time consumer product; it often needs to be used for several years or even ten years. If what you buy at a high price is just a "high-end electrostatic precipitator", you will lose not only money, but also the health and safety of your family.

Therefore, in this field with information asymmetry, it is particularly important to choose a brand that truly masters core technologies.

Since 2015, Kangbeijing has introduced plasma-related technologies from Germany and jointly carried out independent research and development for ten years with expert teams from universities such as Zhejiang University and Lanzhou University, overcoming the core technical difficulty of plasma generators.

Aiming at different spaces and needs, Kangbeijing has built a product matrix of plasma air disinfection and purification covering multiple scenarios such as families, medical care, offices and cultural relic protection, realizing efficient, safe and human-machine coexistent active air purification.

From home bedrooms to Class 100 laboratories, from the protection of cultural relics in museums to the isolation of ICU beds, Kangbeijing, with its DBD plasma core technology honed over ten years, provides a reliable, safe and intelligent air disinfection and purification solution for every breath. Choosing real plasma technology is to reserve a visible peace of mind for your family’s health.
