An inlet, filter cartridge, and sample filter are required to collect a particulate matter sample using an Ultrasonic Personal Air Sampler (UPAS) or Home Health Box (HHB).

The folowing size-selective PM inlets are available for use with our products:

  • PM2.5 @ 1 L min-1
  • PM2.5 @ 2 L min-1
  • Respirable @ 2 L min-1
  • PM10/Thoracic @ 2 L min-1.

Cartridges are available for two filter diameters: 37 mm and 25 mm.

Key accessories for size-selective inlets include:

  • Flow check adapter: Seals over the inlet so the sample flow rate can be checked against an external flow meter.
  • Inlet tool: Used to install and remove inlets on a sampler.
