Airborne Particle Counters

Particle counters monitor indoor air quality and airborne contaminants in large, critical spaces like pharmaceutical/industrial cleanrooms and healthcare facilities. They can also be used in public spaces of commercial buildings or in construction areas to ensure clean air free of contaminants.

Setra's Family of Particle Counters
How do you know your cleanroom is...clean?

If your facility is already monitoring pressure, temperature, and humidity, why guess when it comes to particles? Have confidence knowing your cleanroom is indeed clean all year long.

In this video, Jonathan explains the benefits of particle counting in places like compounded sterile processing (CSP) pharmacies where drug safety and patient health is at stake.

Comparison of Particle Sizes

How small are the particles that Setra’s devices can measure?

Particles are measured in micrometers (0.001 mm), also known as microns (μm). The naked eye can see objects as small as 50 μm, or roughly the thickness of a human hair.

Typical organic particles (e.g. bacteria, mold spores, etc.) range in sizes between 0.5 μm and 10 μm. Setra’s particle counters and air quality monitors can measure particles between 0.3 μm and 25 μm in diameter.

Why should compounding pharmacies continuously monitor particles?

By: Mike Soper (Senior Segment Manager, Critical Environments)
Hospital pharmacies are unique because of the critical role they play in maintaining patient health and safety. Pharmacies that perform compounded sterile preparations (CSPs), in particular, must be prepared in a clean room environment by gowned personnel to ensure sterile conditions are maintained...
