Cleanroom Bioburden Control with Blue Light Disinfection – 24/7 Protection Against Contamination Incidents
From Spikes to Stability
Spectral Blue MWHI® provides continuous bioburden control in cleanrooms using high-intensity blue light—reducing contamination risks, deviations, and downtime. With 100% customer satisfaction.
-
Bioburden levels stay consistently below alert levels after installing Spectral Blue. Fewer deviations mean fewer investigations, less downtime, and lower risk of contamination-related production losses.
Ideal for GMP pharmaceutical, biotech, and medical device cleanrooms where conventional disinfection alone isn’t enough.
☑ Continuous ☑ UV-free ☑ Non-toxic ☑ Chemical-free ☑ Safe for people and surfaces
Critical Control Points for Contamination
Contamination risks aren’t evenly distributed. Spectral Blue MWHI®
delivers the most value where traditional methods fall short—at entry points, on equipment, and in hard-to-reach biofilms. Below are three critical areas where continuous blue light protection can transform your hygiene program.

24/7 PERIMETER PROTECTION
Cut-off rooms and airlocks
70% of cleanroom bioburden originates from personnel gowning areas and people flow. Another 10% is linked to material movement.
Install Spectral Blue MWHI® in these spaces to maintain continuous protection against contamination entering your production.

Critical equipment
Biosafety cabinets and filling machines
Equip your critical equipment with Spectral Blue MWHI to keep it free from microbes—continuously and consistently.
Blue light is safe for staff and materials, and it can be used even when people are present.

WET & DRY BIOFILMS
Washing areas, process water & biofilms
Biofilms are the silent disruptor of your hygiene program. Chemical disinfectants and UVC light struggle to penetrate their protective layer.
Spectral Blue wavelengths can uniquely pass through materials like water, plastic, and glass—and penetrate biofilms to eliminate the microbial colonies within.
