PROBLEM TO BE SOLVED: To provide an air purification apparatus which enables a worker to easily sample particles for test in an air purification section while directly visually observing a sampling probe, and a testing system therefor.SOLUTION: An air purification apparatus 100 comprises an upstream side detection section 111 which captures air outside of a lower casing part 1A at an upstream side rather than an air purification section 2 in the case of a leak test in the air purification section 2 within a casing 1, a sampling probe 8 which is freely movable within an upper casing part 1B at a downstream side rather than the air purification section 2 and captures air within the upper casing part 1B at the downstream side rather than the air purification section in the case of the leak test, a manipulation section 14 which is disposed in the downstream side upper casing part 1B and is manipulated to move the sampling probe 8, and an observation window 115 which is disposed at a position on the manipulation section 14 in the downstream side upper casing part 1B and allows a worker to watch the sampling probe. |
