Begin by filling both nebulizers with solution.
Sensitivity Solution and Nebulizer – Fill the nebulizer with the sensitivity liquid. Unscrew the top half of the nebulizer while holding upright with the bulb facing down. Approximately 3.5cc of solution can test 10-15 people, depending on their sensitivity to the solution.
Fit Test Solution and Nebulizer – Fill the other nebulizer with the Fit Test Solution.
Next remove both white plugs to ensure proper air flow.
Prop both nebulizers upright so that the solution does not leak out.
