AirShield is designed to treat toxic and odorous gases at wastewater treatment plants and industrial facilities. Target gases include H₂S, DMS and other sulfur compounds, amines, aldehydes, terpenes, aromatics and other volatile organic compounds (VOCs).

A stand-alone unit can treat peak concentrations of up to several hundred parts per million—for example, up to 750 ppm H₂S. A site assessment confirms the right configuration for your airflow and pollutant profile.

AirShield is configured around site-specific requirements such as maximum residual emissions and the required removal rate. Field operation has demonstrated removal above 99%. At WWTP Utrecht, odor was reduced by approximately 99.5% to 77 ouₑ/m³ (Olfasense, March 2025; AirShield inlet after existing lava filters: 14,000 ouₑ/m³); at Moerdijk, average removal reached 99.6% for H₂S and 98.2% for total VOCs.

A site assessment determines the expected performance for your airflow.

AirShield supports remote status and performance monitoring through integrated sensor interfaces. Luper can provide emission reporting, performance optimization and predictive-maintenance services.

Where site-specific validation is needed, an onsite pilot can verify performance under real operating conditions.

AirShield uses Luper’s patent-pending gas-phase advanced oxidation process (GPAO). Reactive species oxidize toxic and odorous gases, after which reaction products are captured downstream. This enables broad-range treatment without chemical dosing or biological media.

The TCO depends primarily on treated airflow (m³/h), pollutant load and variability (e.g., H₂S/DMS peaks), operating hours, and the required outlet target. Operating expenses are typically made up of electricity consumption (Wh/m³), planned maintenance and service, and consumables such as filters and sensors.

During a site assessment we provide a TCO estimate for your location, including typical and peak energy use, expected maintenance intervals, and consumables, so you can compare CAPEX and OPEX against alternatives such as activated carbon, biofilters, or scrubbers.

Electricity use depends on airflow, inlet concentration, temperature and humidity. Typical consumption is 0.5–1.5 Wh/m³ for low-concentration airflows and up to 5 Wh/m³ for high-concentration airflows, including the fan. Sensor feedback lets AirShield match operating power to the pollutant load. During a site assessment, we estimate typical and peak energy use for your airflow.

No, the AirShield uses electricity and the water and oxygen naturally present in the air to generate reactive species in-situ for oxidation. Any residual reactive species are converted downstream using an integrated catalyst.

The yearly maintenance is designed to be straightforward and can be performed by a trained operator, a local service partner, or our team, depending on your preferences.

Tasks include inspection, checking sensors, and scheduled replacement of consumable components. We can provide service agreements and planned maintenance to ensure reliable performance. If desired the AirShield can be equipped with sensors for predictive maintenance.
