Common car air purifiers are mainly designed with HEPA filters, which can not only purify PM2.5, but also have functions such as detecting PM2.5 level and releasing negative ions. However, due to the power limitation, its air output is usually relatively small.
In addition, there is another way to purify the air and remove formaldehyde and smoke odor through active oxygen, i.e. ozone sterilization, but ozone can irritate the mucous membranes of the human respiratory tract, so it can't be used when a person is in the car, so there are some limitations.
Next, take a look at this car air purifier. Its body is made of ABS heat-resistant material that can withstand temperatures up to 72 degrees. The air inlet is located at the top, and the part with white wave stripes occupies most of the area.
Its HEPA filter has a side-pull design for easy replacement. The built-in HEPA filter is of medical grade, with an official claim of 99.97% purification rate for PM2.5 and 0.3 micron particle filtration. After 240 hours of accumulated use, the purifier will automatically remind you to replace the filter. In addition, it has a built-in DC fan module with a speed of 2070 rpm, which provides stable and large airflow, low noise and long service life.
The air outlet of this car air purifier is located at the front of the body, where the air quality indicator is also located, with three colors of green, yellow and red, corresponding to good, poor and bad air quality respectively. It has a built-in dust sensor with intelligent sensing and automatic high purification. Along with the HEPA filter and detection of air quality, it also has a built-in negative ion generator to eliminate some of the odors.
It has three adjustable speeds - auto, one and two - and is controlled via a high-definition touch panel with no physical power on/off button. The design is more humanized as it starts automatically when the ignition is turned on and turns off when the ignition is turned off. The touch control is sensitive and the buttons have indicator lights, blue for power on and red for power off.
There are two USB ports on the side of the body to meet the demand for charging cell phones, which is very practical for users who only have a cigarette lighter jack. However, the original car charger is a one-piece design with a round hole plug and a micro USB connector, which limits the usage scenarios to a certain extent. The red part on the top of the car charger is the press type power switch.
To simulate the smoking environment in the car, take a colleague who often smokes in the car as an example. Cigarettes are burned completely and left in the car, the vehicle is a Volkswagen Ranger. The air purifier is placed in the front windshield, and the air fruit is placed in the center of the back seat. At the same time, the airflow was adjusted to the maximum, and the status of the air inside the car was checked through the APP. the PM2.5 value changed from 184 to 45 after 6 minutes and to 33 after 10 minutes, which is a significant effect on the filtering of cigarette smoke. After entering the car and closing the door, there is no longer any obvious smoke odor left, and the leather smell of the car seat after sun exposure can also be effectively reduced.
