ouE/m³ residual odor
Measured after AirShield treatment
“The main odor problem came from sulfur-based compounds released during sludge treatment.

Luper’s AirShield removed them completely.”

The AirShield turns air cleaning into a reliable process
Designed for variable, humid industrial airflows where conventional odor control can struggle during peaks
Prevent odor complaints
Maintain effective odor treatment under variable operating conditions
Treat complex gas mixtures
Breaks down H₂S, VOCs, NH3 and other odor-causing gases
Protect against spikes
Automatically increases cleaning power during odor peaks
Operate without chemicals
No chemicals or biological start-up required
Built for teams who need odor control that just works
For process technologists, asset owners, and facility operators who need measurable odor control and reliable daily operation for real industrial sites.
Asset managers
Facility operators
Process technologists
Demonstrate compliance
System emissions are continuously monitored to demonstrate compliance with permits
Lower costs
Reduce total cost of ownership by up to 60% compared to activated carbon
Reduce interventions
No chemicals, micro-organisms or rapidly saturating media that force unscheduled interventions
Save space
A compact system with up to 10x lower footprint than a biofilter
Generate insights
Continuous monitoring provides insights in upstream processes
Reduce complexity
A compact, modular system that fits into existing infrastructure with minimal civil modifications
Operate with confidence
A design to handle temperature, humidity and concentration swings provides confidence in operation
Save time
A yearly maintenance cycle and status indicators save time spent on maintenance
Design with confidence
Treat complex gas mixtures and emission spikes in a single system
Eliminate pathogens
Kill bacteria, viruses and other micro-organisms to below background levels
Specify based on data
Accredited, third-party measurements provide verified removal data per compound
Lower CO2 footprint
Reduce CO2-eq footprint by 5x compared to activated carbon
Built for challenging airflows
Choose the right odor-control technology around load variability, gas composition and operating conditions.
Biofilter
Carbon filter
Luper AirShield
Working principle
Biological degradation
Adsorption in carbon media
Electric advanced oxidation
Best suited for
Stable, sustained, medium loads
Dry, low-load airstreams
Emission spikes, gas mixtures
Less suited for
Emission peaks, VOCs
High humidity, sulfides, amines
Dry, oxygen deprived gas
Key considerations
Large footprint, biological start-up
Media replacement and disposal
Requires electrical power
