With the conservative estimation of a 4.1 µg/m 3 decrease in PM 2.5 and RRs from the MCC study, we found that 37.6 (95% CI: 32.6, 42.5) non-accidental; 7.0 (95% CI: 5.7, 8.4) cardiovascular; and 4.7 (95% CI: 3.4, 6.1) respiratory mortalities were avoided because of the reduction in PM 2.5 from January to April in 2020 compared to those of the previous 4 years. Because using a particulate-filtrating respirator may decrease the absolute level of PM 2.5 exposure for an individual, the health benefit related to air pollution during the COVID-19 crisis may be larger than our current estimation of 37 persons.	./cache/cord-304780-lbq70q11.txt	./txt/cord-304780-lbq70q11.txt
