Fig 2.
Cumulative size distributions by volume for the total 360 sprayer, at 6-foot distance, when spraying different liquids.
Blue line = deionized water; red line = tap water; Grey line = disinfectant with dichlor as the active ingredient; Yellow line = disinfectant with hydrogen peroxide as its active ingredient.
