01
The smell of the new car will continue to swing in two or three years
New cars, not just seats, including other interiors, are inherently delicious。
In general, spare parts for a vehicle are manufactured and packaged in the shortest possible period of time, and the odour tests will then be conducted at a temperature of 21°c ~ 25°c and a humidity of 40 to 60%。
At this point, the smell is greatest in seats, car inside boards, carpets, which are generally processed by the factory before the vehicle enters the sales chain。
So when users get a car, they usually have a "new car smell."。

In addition to the discomfort of the smell of the new car, the high temperature of the sun may lead to higher levels of formaldehyde in the car, the tan and volatilizers, which endanger health。
02
It smells in the old car
Three or four years in old cars, you can smell it in the car. For example, air conditioners, particles such as dust and dust enter air conditioners, which tend to accumulate in windways, mold and soot。
For domestic cars, air-conditioning evaporation and filters are the most important breeding areas for bacteria。
The hot air flows through the cold evaporation unit into the vehicle, while the water in the air condenses and remains on the evaporation unit, so that the cold humid environment is particularly suitable for bacteria to breed。
If you can smell air conditioners, it means there's a lot of bacteria in them。
The car may also have the smell of smoke, summer sweat, food beverages spilled in the car, even because of poor maintenance and the smell of mold in the interior。
Part02
How do you remove the smell in the car
There's something that we can do with purpose。
For example, air conditioners are moldy, interiors are moldy, and can be kept clean and clean by regular cleaning to avoid bacteria。
But what if after cleaning the air conditioning, the interiors or the smell of the car
The following approaches could be tried:
One, open the window
Frequent window ventilation is the most direct method of accelerating the flow of air inside the vehicle and contributing to the elimination of the aroma and formaldehyde in the air inside the vehicle。
Ii. Activated carbon or formaldehyde
Active carbon is a material with adsorption function that can effectively adsorb harmful gases in the air, such as anti-venom masks containing some active carbon。
We put activated carbon bags in our new car, so that harmful gases in the car can be desorbed。
Iii. Use of vehicle-borne air purification units
Some of the higher requirements for owners may choose to install vehicle-mounted air cleaners, which can be a good way to remove the aerobics from the vehicle, although relatively expensive。
Iv. Use of formaldehyde aerosols
Spraying of some dealdehyde sprays in the corner of new vehicles, cushions, etc. Can also remove some degree of formaldehyde, odor, bacteria etc。
V. Ozone disinfection or photo-media desorption services
At present, many specialized car beauty shops have a new carowner service, who can choose professional light-tasking, ozone machines and other deodorant equipment, which can be used for one-time clean-up of contaminated sources, but at relatively high cost。
