What is the hood particulate filtration efficiency at 0.1 to 1.0 microns?

• A. 94%
• B. 96%
• C. 98%
• D. 92%

Answer: (B)

The main idea here is how well the hood’s filter removes airborne particles in a specific size range. Filtration efficiency tells you what percentage of particles between 0.1 and 1.0 microns are captured before the air reaches your breathing zone. For this hood, a performance around the mid‑90s is typical, since many aerosols of concern fall in this size range and the filter design aims to block most of them. A value of 96% means about 4% of those particles could still get through, which is a strong level of protection for this type of hood filtration. Among the given numbers, 96% best matches the expected performance in this range, being higher than 92% or 94% while not implying an unrealistically high efficiency like 98%. This reflects solid protection without overclaiming what the hood’s filtration system can deliver.
