What is The Main Air Purifier Principle Technology? Jul 19, 2021

There are some different air purifier and disinfection work principle.


Distinguish by “Man-machine symbiosis”

1)Unfit together. Usually the Ozone Generator technology will use when nobody nearby.  According to international standards, it can cause discomfort such as thirsty when it reaches 0.5-1ppm; it can cause cough when it reaches 1-4ppm; It can cause a strong cough when it reaches 4-10ppm . Therefore, when using ozone to disinfect air, it must be in an unmanned place and at least 30 minutes after disinfection before entering. Ozone disinfection can also be called accelerated aging process.


Meanwhile, when working voltage between 5000 Volts to 6500 Volts, the air will easily release extra ozone which will exceed the test standard 0.1mg/m3 via GB/T 18801-2015. Our DUUHNN company air purifier and disinfection work voltage is just between 1300Volt to 2200Volt. At this range the ozone is rather less and quite safe.


Additional, the "High Energy Ion Tube" and "UVC Light External" will not fit to use when Human and Machine Coexistence condition.


2) Fit together. For "Negative Ion" " High Voltage Static" "Plasma Generator" work principle can fit man-machine together.

Our DUUHNN SPI technology belong to "Plasma Generator" but much higher concentration negative and passive ion to purify the air.


Now we list some different technologies to compare its advantage and disadvantage as below:

Advantages and Disadvantages

Reduce dust and clean air/Easy to ablate and high voltage accumulation interferes with electrical work

Easy to desorb and difficult to maintain, easy to Arc flashover,High by-products (ozone)

Poor consistency, High by-products and greatly affected by the environment

Easy to ablate and large structure,usual used for household/office/car

Strong oxidizing property and accelerate the aging of items

High ion concentration,  no by-products, and low voltage,great for medical air disinfection

 

Generally speaking, the HEPA filter just make the bacterial virus particles drop on them but not kill dead. SPI technology will solve "to kill vacterial virus" issue well.
