The city of Montreal states that the main pool can accommodate 1,150 bathers while the "Montreal Gazette", in 1951, reported that the pool could handle up to 6,000 swimmers on a daily basis.

Indoor bioaerosol devices to air ventilation system to inlet filtered outdoor air into indoor environment; 4) reducing/removing contaminant sources (i.e., indoor organic waste). As in the U.S., due to the increase in tuberculosis in the mid-1980s, indoor air treatment has developed substantially during the past two decades. Current or developing indoor air purification technologies include filtration, aerosol ultraviolet irradiation, electrostatic precipitation, unipolar ion emission, and photocatalytic oxidation. Indoor bioaerosol Indoor bioaerosol is bioaerosol in an indoor environment. Bioaerosols are natural or artificial particles of biological (microbial, plant, or animal) origin suspended in the air. These particles are also referred to as organic
