In-duct · whole building

The HVAC

Our flagship in-duct system. Fitted inside the ductwork you already have, it turns the air conditioning that currently circulates contamination into the thing that removes it.

The HVAC unit

Why this unit

Coverage
800 – 3,300 sq ft
Mounting
Installed into existing ductwork
Best suited to
  • Large commercial spaces
  • Offices
  • Schools & daycares
  • Hospitals & clinics
  • Nursing homes
  • Hotels
  • Distribution centres

The HVAC unit installs directly into existing ductwork and works in tandem with the incoming airflow from your air handling system. As air passes across the ARC® cell, cleaning agents are introduced into the ducting and carried through the whole building.

That distribution is the point. Because the agents travel as a vapour with the air, coverage is even across every served room, including the parts of the building nobody thinks to clean, and the inside of the ductwork itself.

Keeping ducts clear of contaminant build-up also reduces strain on the system. Cleaner ducts mean more efficient airflow, better performance from the air handling equipment, and less mould-related maintenance over the life of the installation.

  • Retrofits into existing systems

    No replacement plant, no redesign. It fits the ductwork already in the building and works alongside your current air handling units.

  • Even air distribution

    Uses the duct network you already have to distribute treated air evenly, giving comprehensive coverage across large or subdivided spaces.

  • Keeps ductwork clean

    Actively reduces contaminant build-up inside the ducts themselves, improving airflow efficiency and the working life of the equipment.

  • Low maintenance

    Straightforward to monitor and service, with no daily intervention required from building staff.

Test results

Published studies on this unit.

Each is shown with the exact configuration, technologies, duration and administrator that produced it.

Field test

Occupied workplace, no filter fitted

>99.99% reduction of airborne mould spores

Commercial office, active solution

The in-duct unit running as an active solution alone, with no filtration assistance, isolating what the technology itself contributes.

“It is my considered observation that pureAir HVAC does provide a rapid and significant reduction of the typical contaminants tested. The levels achieved and maintained during this test were far below any known standard or established TLV. It is my considered opinion that this sustained condition would not be typical or possible without the continuous use of this product.”

Field test

1,240 sq ft, HVAC unit paired with a treated filter

>99% reduction of airborne mould, bacteria, TVOC and odours

Commercial office, active + passive

The same environment with an ODOGard®-coated MERV 13 filter added. This is the configuration we specify by default, and the difference it makes is the clearest argument for treating active and passive technology as one system.

“It is my considered observation that HVAC in combination with an ODOGard coated filter does provide a rapid and significant reduction of the typical air and surface contaminants tested. In my considered opinion, the sustained condition would not be achievable without the continual use of the technology represented.”

Get in touch

Start with the building, not a quote.

We begin by understanding the environment and what's actually driving the problem: the building, the air handling, and how the space is really used. What you get back is a specification built around that, not a quote against a template.

  1. 1

    We review what you've told us and come back within one working day.

  2. 2

    A site assessment covering the space, the air handling system, and what's actually driving the problem.

  3. 3

    A written specification and a fixed price, including the ongoing service interval.
