Terms like FFP2 and N95 are confusing but refer to the differing amount of airborneparticles that the mask can remove:像FFP2和N95這樣的術語指的是口罩能快速移動的空氣中粒子的不同數量
European mask standards categorize masks into FFP1, FFP2 and FFP3 which remove 80%, 94% and 99% respectively. 歐洲口罩標準將口罩分為FFP1、FFP2和FFP3，指能分別去除80%、94%和99%的顆粒。American standards use a slightly more intuitive system N95, N99 and N100 removing 95%, 99% and 100% of particles.美國標準使用更直觀的系統N95、N99和N100，指去除95%、99%和100%的顆粒。Each 3M N95 can be purchased in some 7-elevens & JD.com Alternatively, Californian company

Plants to Clean Your Air

美國國家航空航天局公布的一項研究稱，蜘蛛植物(吊蘭)、魔鬼藤(金蓮花)、和平百合(刺葉百合，莫納羅亞)和各種蛇類植物(三花杉)對家居空間有好處。但它們並不能替代空氣清潔及過濾技術。
Make Good Decisions
改變生活方式
Whilst you can’t do anything to change the air quality outside, you canmake good decisions to minimize your exposure to it:
我們無法改變空氣品質，但可以改變一些生活方式，儘量減少接觸汙染物:In a city where smoking is so cheap and engrained in both dining and business culture, sitting in a bar without a cigarette might feel like an alien idea. However, cutting out smoking is a sure fire way to improve your health.在一個吸菸如此廉價、餐飲和商業文化都根深蒂固的城市裡，坐在酒吧裡不抽菸可能會讓人覺得很奇怪。不過顯而易見的是，戒菸是改善健康的最佳方式。

This can really minimize your exposure to the pollution.尖峰時間儘量避開繁忙的道路，選擇騎自行車、乘地鐵或公共汽車出行。這可以減少你在汙染環境下的時間。Xi'an is one of China's most congested cities Monitor the AQI, time your workouts effectively and use side roads or river paths to avoid direct traffic fumes. Whilst most gyms here still don’t have purifiers, indoor air generally has around 50% less pollutants than the air outside.監測空氣品質指數並有效地安排你的鍛鍊時間。可以選擇偏路或河道來避免接觸路邊交通汙染物。儘管大多數健身房還沒有空氣淨化器，但室內空氣中的汙染物也通常比室外少50%左右。Indoor exercise has become easier
Air pollution’s long term health impacts often build up slowly over time, but even if you’re not in Xi'an for the long run, it’s still sensible to take precautions and make good decisions.
隨著時間的推移慢慢累積，空氣汙染一定會對健康產生影響。即使你不在西安長期生活，也希望能在極端天氣下採取預防措施。新聞 活動 旅行 城市獵人NEWS EVENTS TRAVEL CITY HACKS
