We tested the filtration efficiency of Stryker T5 surgical helmets with and without the addition of a filter medium. Two particle counters were used to count the particles of sizes .5 mum, 1 mum, and 5 mum, both inside and outside the Stryker T5 helmet, concurrently. The total inward leakage (TIL) for the helmet with and without the filter was zero for 5 mum particles at all time points. The TIL (3.4) for the .5 mum particles decreased significantly after application of the filter (1.7; P = .007). We recommend that an N95 should be used inside the helmet system.
