公共交通機関は新型コロナウイルス感染の新たな隠れた危険地点となり、感染リスクも高く、バス、タクシー、地下鉄などの交通機関で感染・発病した事例が相次いでいる。防疫期間中、交通分野での防疫管理（座席間隔の確保、乗車券販売数の削減など）を強化し、公共交通機関でのウイルス感染リスクを減らすとともに、運転は最も安全な移動手段となっている。
しかし、車で旅行するのは本当に安全なのでしょうか?
実際、自家用車の運転は地下鉄やバスに比べて新型コロナ肺炎患者との接触確率を効果的に減らすことができますが、車自体が密閉された環境であるため、乗客に感染者がいると、感染する可能性も大幅に高まります。そのため、ある程度までは運転が最も安全な交通手段であるとはいえ、車を運転する際には必要な防護措置を無視してはいけません。ここで述べた安全対策に加えて、やはり濃厚接触を減らし、マスクを着用し続けなければなりません。密閉された車内環境でウイルスが発生源から空気感染する確率を高める問題をどのように解決するかは、さらに検討する価値があります。これは流行時だけではなく、安全対策を考慮する必要があるからです。流行時以外でも、車内の空気の質は私たちの健康と快適さに深く関係しています。
How to improve the air quality in the car? In-car air quality has always been the focus of consumers’ attention. The new car quality research (IQS) report of the world’s authoritative research organization J.D. Power shows that car interior odor has become the first dissatisfaction in the Chinese market for many years. The main factors affecting air safety in the car are: 1. Air pollution outside the car. Car exhaust, PM2.5, pollen and other harmful suspended particles sneak into the car through the car window or air conditioning system. 2. Interior materials. There are a large number of non-metallic parts that are easy to volatilize in the car, such as plastic door panels, leather seats, and damping panels. There are 8 common volatile organic compounds in vehicles, and clear limits are given for these 8 substances in the national standard GB/T 27630-2011 “Guidelines for Air Quality Evaluation of Passenger Cars”. Serial number project Restriction requirements (mg/m³)
1 benzene ≤0.11
2 Toluene ≤1.10
3 Xylene ≤1.50
4 Ethylbenzene ≤1.50
5 Styrene ≤0.26
6 formaldehyde ≤0.10
7 Acetaldehyde ≤0.05
8 Acrolein ≤0.05
In order to solve the peculiar smell in the car and improve the air safety in the car, it is necessary to increase the cycle purification link in the closed car environment, and there is no doubt that the car air conditioning filter has become an important responsibility. The car air conditioner provides the original power for the exchange of indoor and outdoor air, but in order to satisfy the purification of the indoor circulating air, the outdoor air enters the car after being filtered. The filter becomes an essential artifact for the car owner! The small body shows great power, creating a safe and reliable space in the car, allowing car owners to enjoy healthy breathing at all times. Editor’s reminder: In order to avoid secondary pollution of the car air conditioner filter, generally speaking, it should be replaced after two to three months of use (the specific replacement frequency can be considered according to the actual frequency of use)
