Introduction. Defining the interrelation between the inspiration resistance in workers using air purifying respirators and their working capacity is of significant interest. These relations are important for designing, engineering and improving filtering personal respiratory protective equipment (RPE).

Purpose of the study is to study the influence of microclimatic conditions on workers’ working capacity while using respirators. Materials and methods. DSTU GOST 12.4.061:2008 "The Occupational safety standard system. Method for determination of working capacity of man fitted with individual protection means".

Results. While performing a task on a running machine with a load, using a respirator with P2 class filters and the inspiration resistance of 75–80 Pa and different microclimatic parameters it is established that working capacity decreases by 26 % under comfortable conditions (temperature and relative humidity are (20 ± 2) °С and (65 ± 2) %) and by 64 % when the work is in extreme conditions (temperature and relative humidity are (30 ± 2) °С і (85 ± 2) %).

Conclusions. New data on the influence of air purifying respirators on a person’s working capacity in climatic conditions similar to those of mine workers has been obtained.
