The air purification specifications and technical parameters


Suitable for single return air conditioner    



Suitable for double return air conditioner


Pollutant project Initial concentration of pollutants Ratedair volume(m3/h) Working 1h removal rate (%)
Formaldehyde (HCHO) 0.96~1.44mg/m3 4800 90.4%
Toluene (C7H8) 1.92~2.88mg/m3 4800 91.4%
Xylene (C8H10) 1.92~2.88mg/m3 4800 93.0%
Total volatile organic compounds (TVOC) 4.8~7.2mg/m3 4800 92.2%
Particulates 0.70~0.85mg/m3 4800 99.9%
Microorganism According to GB 21551.3 4800 99.9%
Test conditions: 12-meter large passenger car, 6 evaporator fans, maximum air flow operation, internal circulation 

Strong ions have a very strong redox ability, can oxidize and decompose formaldehyde, methane, ammonia and other volatile odor gases (VOC) in the vehicle into cabin bon dioxide, water and oxygen. The removal rate reaches 95% after 1 hour of operation. 


On-sit test: After 25 minutes of in-depth purification, PM2.5 was reduced from 759 μg/m3 (six-grade heavy pollution) to 33 μg/m3 (first-class air quality), and the air quality was significantly improved. 


1. In the co-existence mode, the ozone generation amount is 0.05ppm, which is far less than the safety value of 0.15ppm. The sterilization rate reaches 99% after 30 minutes of operation.

2. Ultraviolet does not have penetrating power and does not cause any harm to the human body when it is not directly irradiated; there is a photocatalyst layer, grille filter layer and grille door panel between the ultraviolet sterilization lamp and the cabin to prevent direct exposure to passengers , Can be used safely. 

Ozone concentration Sterilization rateat 0.05PPM concentration Sterilization rateat 0.1PPM concentration
operating hours 15 minutes 30 minutes 15 minutes 30 minutes
Staphylococcus aureus 75.1% 86.3% 81.8% 98.2%
E.coli 83.5% 93.8% 92.7% 98.6%
Typhoid bacillus 91.2% 95.5% 95.9% 99.4%
Natural colonies 93.7% 99.8% 98.6% 99.9%
Test conditions: Use 0.05ppm and 0.1ppm O3 concentration to test its sterilization effect and sterilization rate in a 200L closed container. 

The air purification system features and advantages

1. Four core technologies   

Air quality improvement

Items Electrostatic dust collection (PM2.5) UV lamp ionizer  Photocatalyst filter
Sterilization ×
Remove VOC ×
PM2.5 × × ×

2. Strong ion photocatalytic polymerization technology, human-machine coexistence, disinfection and sterilization:

Proprietary strong ion technology, combined with UVC ultraviolet, active oxygen, negative ion and photocatalytic polymerization technology, comprehensively and quickly kill viruses and bacteria, and prevent the spread of disease. The sterilization rate is 99.9%, and the dust removal rate is 99.9%. It can effectively remove harmful gases such as formaldehyde, benzene, ammonia, and various odors, smoke, and odors in the vehicle cabin. It has a working mode of human-machine coexistence, disinfection without dead ends, and pollution.

3. Supplement air negative oxygen ions to eliminate travel fatigue.

6 million negative oxygen ions, refresh the air, activate cells, enhance human immunity and eliminate travel fatigue.

4. Air purification, decomposition of harmful gases, maintenance-free and no consumables.
Installed inside the air conditioner grille, small size does not occupy additional space, through the chain reaction to strongly decompose the polluted gas in the cabin, eliminate PM2.5, PM10 suspended particles, keep the air environment in the car fresh and healthy, no consumables during use , Maintenance free. 


5. Remote monitoring, safety warning, intelligent control.

It can be connected to the CAN line of the whole vehicle, and the air quality sensor data can be monitored in real time on the dashboard, and the intelligent switching and real-time safety warning of the purifier's working mode can be realized according to the air quality; the return window has its own independent display (display PM2.5 particle concentration, temperature, humidity and air quality index, optional), allows passengers to intuitively understand the pollution status of the vehicle environment through the display, making the product more higher-class and practical in appearance.

6. High working efficiency, low power consumption, minimal impact on vehicle energy consumption or cruising range.

"Dynamic polarization" mode guarantees long-lasting and stable purification efficiency, the dust holding capacity is several times higher than the filter of the same specification; matched with the power supply system of the passenger vehicle, the power consumption of the disinfectant purifier module of the 12-meter bus is only 10W, safe and energy-saving, suitable Equipped with ordinary and electric buses.

Core Competitiveness of SONGZ Air Purifier

Product Power

SONGZ air purifier

Integrated purification function

Does it require ventilation? Ventilation by fans No vent
Air purification method 1. Strong ion air purification system2. Enhanced ozone module (optional)3. Integrated electrostatic dust removal

4. Integrated photocatalyst filter

5. Integrated UV sterilization

1. Vehicle UV lamp sterilization2. Spraying disinfectant solution
Core competitiveness  1. Overall integration, small size, very few changes to the vehicle
2. Can effectively remove all kinds of bacteria, viruses, dust and toxic and harmful gases
3. The overall cost of the purifier is low. If you want to install an enhanced ozone module, you only need to add an additional cost of more than 100 RMB.
4. The air purification function can be turned on when carrying passengers. The air purifier itself will generate a small amount of O3 (about 0.02ppm, within a safe range) to achieve real-time sterilization effect.
5. When anti-virus is needed for the whole vehicle, before the vehicle is turned on or when there is no one in the car, the enhanced ozone mode is turned on, and it will automatically stop after 15 minutes, which is highly efficient and energy-saving.
6. When the cooling, heating and ventilation modes are not turned on, the fan of the sterilization system is started automatically for 5 minutes and stopped for 20 minutes.
1. Large changes to the whole vehicle, it is necessary to install extra ultraviolet lamps in the vehicle, and a whole set of disinfection water spray system needs to be installed. The rectification project is large and the cost is high.
2. Bacteria and viruses can be cleaned, but there is no good treatment for dust and toxic and harmful gases.
3. Air purification and disinfection are not allowed when carrying passengers. If do and after disinfection, then air exchange is required, and this efficiency is lower.

Application Cases of SONGZ Air Purification System

At present, it has been supplied in batches on higher-class models of OEMs such as Xiamen Jinlong and Zhengzhou Yutong. 


We hope to work together with you to improve the environment during people travel and improve the air quality inside the vehicle!
