Does anyone have experience with the Leland Legacy air sampling pump (10L/min) and also something with a lower flow rate such as a SKC AirChek (1-5L/min)? Specifically, the tradeoff between noise and sampling rate - is the Legacy so noisy that it couldn't be used at home/in an office? It is obviously better from a PM mass collection viewpoint, but we also need something which runs quietly enough to be used at home or in other locations where it won't cause disturbance.
We have done some work about personal monitoring in Hong Kong and Guangzhou, China using the Leland Legacy sampling pump. We did not receive complaint about the noise issue.
A noise-reducing case is necessary. You can put the pump in a sealed box (e.g., shaped like an AirMetrics sampler) filled with sponge, and it can runs quietly in the office. The pump can be set in the living room while sleeping.
