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

PM_2.5 @ 1 L min^-1
PM_2.5 @ 2 L min^-1
Respirable PM @ 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.
