The firework firestorm last year in Beijing led to a surge in the PM 2.5 reading to more than 500 micrograms per cubic meter on Lunar New Year's Eve.
Shanghai just experienced one of its most polluted months in December, with only eight days reportedly having decent air quality.
On the eve of the 2013 Chinese New Year last February, the index of PM2.5 pollutants -- particles smaller than 2.5 micrometers in diameter that are considered especially harmful -- soared to 524 micrograms per cubic meter around midnight.
A local Beijing resident says celebrating the Lunar New Year should not be come at the cost of poor air quality and people's declining health.
"Setting off fireworks is a tradition during Chinese New Year and it creates an atmosphere of celebration. The sound of the firecrackers makes me feel that this is a New Year, but setting off too many of them is inappropriate, given the severity of the air pollution -- setting off a little bit will be just fine."
Efforts are also being made to provide cleaner alternatives to traditional fireworks.
Local fireworks company Jinqilin, responsible for supplying fireworks to the city's retailers, said it would introduce a new type of "green" pyrotechnic this year, which they claim will account for half the wholesale market.
