CO₂ FILTRATION FOR BUILDINGS
Healthier indoor air. Up to 15% lower total building energy use. Using the HVAC you already have.
Maxairea filters CO₂ out of supply air, so HVAC systems need less outdoor air — cutting heating, cooling and fan energy while maintaining excellent indoor air quality.

The problem
Why ventilation costs so much energy
It happens in four simple steps.
- 01
People breathe out CO₂
Every person in the building adds CO₂ to the air, all day long.
- 02
Outdoor air is pulled in
The only way to get the CO₂ down is to dilute it with fresh outdoor air.
- 03
That air must be conditioned
All that outdoor air has to be heated, cooled and pushed around by fans.
- 04
The energy bill goes up
Conditioning ventilation air can be up to a quarter of a building's energy bill.
Ventilate less and people notice. Ventilate more and the bill grows. That is the trade-off we remove.
What you gain
Remove the CO₂, and the trade-off disappears.
One change at the air-handling unit, four things you get back.
Fresher air
CO₂ stays low all day, so meeting rooms and busy floors stay comfortable.
Class A air at TEMA Fine FoodLess energy used
Less outdoor air means less heating, less cooling and less fan power.
Up to 15% lower energy useKeep your HVAC
We add the unit to your existing air handler in the technical room. No new ducts.
Retrofitted at SPIE, ElslooNothing to replace
The CO₂ filter cleans itself while it runs, so there is no cartridge to swap.
Regenerative by designHow one change flows through the building

How it works
Air in. CO₂ out. Filter restored. Less outdoor air to condition.
Maxairea removes CO₂ directly from building air using regenerative filtration and intelligent heating, ventilation and air conditioning (HVAC) control. By reducing the amount of outdoor air needed specifically for CO₂ dilution, Maxairea helps avoid unnecessary overventilation while maintaining high indoor air quality — lowering heating, cooling and fan energy demand.
Conventional ventilation
Full outdoor-air volume heated, cooled and moved to dilute CO₂.
With Clever Air Care
Up to 50% less outdoor air to condition, with 24 m³ of fresh air per person per hour always retained.

What happens next
Three steps, and you know where you stand.
- 1Assess your building
You share building type, occupancy, operating hours, ventilation design and current energy use. We establish a measured baseline.
About 30 minutes of your time - 2See the opportunity
You receive a building-specific view of achievable outdoor-air reduction, energy saving, indoor air quality impact and installation approach.
Within two weeks - 3Install and verify
We integrate the system into your air-handling unit around your operating schedule, commission it, and measure performance against the baseline.
Planned around your building
Where it fits
Buildings with high occupancy and long operating hours.
Offices
Dense meeting rooms and peak-hour occupancy driving oversized ventilation.
Hotels
Guests pay for comfort — savings cannot come from running the system less.
Schools & universities
CO₂ levels affect concentration; Frisse Scholen sets clear IAQ expectations.
Theatres & cinemas
Very high occupancy in short bursts, with large ventilation swings.
Shopping centres
Long operating hours and large conditioned volumes.
Public & healthcare buildings
Strict air-quality requirements alongside energy-performance obligations.

Maxairea nominated for the KVK Innovation Top 100 2026
Maxairea has been nominated for the Chamber of Commerce Innovation Top 100 2026. Public votes count for 20% of the final result, and voting is open until 19 October. We are proud of the nomination and grateful for every vote of support.

TNO reviews scientific research on CO₂ and airborne virus stability
In 2026, TNO reviewed a number of scientific publications for Maxairea on the potential relationship between indoor CO₂ concentrations and the infectivity of SARS-CoV-2 in aerosols. The key findings and referenced scientific sources are summarised in the accompanying reports. Controlled laboratory studies indicate a possible mechanism, but this has not been validated as an infection-control benefit in occupied buildings.

Maxairea is a finalist for the Vakbeurs Energy Innovation Award 2026
Maxairea has been named a finalist for the Energy Innovation Award 2026, recognising our regenerative CO₂ filtration technology for cleaner air and lower building energy use. The award will be presented at Vakbeurs Energie, Brabanthallen Den Bosch, on 6 October.
Before you get started
Questions building owners ask
Will Maxairea replace my current HVAC system?+
No. Clever Air Care is added to a suitable existing air-handling installation. The building assessment confirms how it integrates with your specific system.
How much energy will my building actually save?+
Engineering calculations indicate up to 15% of total building energy use in high-occupancy buildings with long operating hours. Your result depends on occupancy, operating hours, climate, ventilation demand and the current efficiency of your HVAC. We will not quote a figure for your building before the assessment.
Does less outdoor air mean worse indoor air?+
No. CO₂ is removed rather than diluted, and the controller enforces a minimum of 24 m³ of fresh air per person per hour at all times. IAQ is measured continuously and reported.
Will installation disrupt operations or add maintenance?+
Installation takes place in the technical room and is planned around your building's operating schedule. The filter is regenerative, so there is no consumable media to replace as part of routine HVAC maintenance, subject to the final system design and service agreement.
Can the result be defended to an auditor or asset manager?+
Yes. Every project uses a pre-installation measured baseline and post-installation verification of CO₂, airflow and HVAC energy consumption, so the improvement is documented rather than asserted.
