Prevent odor complaints
at wastewater facilities

Eliminate peak emissions and prevent gas breakthrough with advanced oxidation of organic and sulfur compounds

Explore our AirShield

The AirShield turns air cleaning into a reliable process

Prevent odor complaints

Accredited measurements show residual odors as low as 75 ouE/m³

Treat complex gas mixtures

Breaks down H₂S, VOCs, sulfides, amines and other odor-causing compounds

Protect against spikes

Sensor-driven odor control adapts cleaning power to real-time odor load

Monitor performance

Integrated sensors continuously monitor system performance

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.

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

Biofilter

Carbon filter

Luper AirShield
