Live environment

96.4% reduction of Stachybotrys

Occupied apartment block

72 hours · Live field trial

Data and test conditions

A 72-hour trial in a genuinely contaminated, occupied apartment block, not a chamber. Spore concentrations fell sharply across every classification present, including Stachybotrys, the species associated with significant water damage.

98.21% bioaerosol reduction of MS2

Aerosol deactivation of MS2

4 hours · Aerosol Research & Engineering Laboratories

Data and test conditions

MS2 is an established surrogate for influenza and SARS-CoV-2. The unit reduced the aerosolised virus by an average net log of 1.86 ± 0.38 within four hours, demonstrating capability against airborne bio-aerosols rather than surfaces alone.

“It is my considered observation that the 750+ Wall Mount does provide a significant reduction of the typical air and surface contaminants tested. ASHRAE provides guidance as to the use of supplemental air purification after increasing fresh air ventilation to a minimum of 6 air changes per hour and filtration to MERV 13. This study was performed without those improvements. It is my considered opinion that if this unit was used within the current ASHRAE guidelines an even greater efficacy could be expected.”

Educational facility

5 days, measured in real time · Advanced IAQ Solutions (IAQS)

Data and test conditions

A deliberately hostile gas-phase environment: a sealed store of cleaning chemicals inside a school. Both TVOC and formaldehyde fell substantially over five days of real-time measurement.

“There was a significant reduction of TVOC and HCHO from the initial readings which would not have been expected to occur without the introduction of this combined technology.”

“It is my observation and considered opinion that the technology had a significant effect on stabilizing the indoor air environment as well as definitively reducing airborne contaminants as defined by the readings. No single technology alone would produce those results.”

Data and test conditions

A hospital ran a four-week real-world study across active ambulances. Enclosed, high-turnover and time-pressured, they are among the hardest environments to keep clean, and among the highest-consequence.

“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.”

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.

>99.99% reduction of mould on fan and coil surfaces

Student residence

5 days, measured in real time · Advanced IAQ Solutions (IAQS)

Data and test conditions

The most direct evidence we have that the inside of an air conditioning unit is itself a contamination source. Viable mould on the fan housing and coil surfaces was removed completely, whether the unit ran continuously or only on temperature demand.

“The use of the PTAC unit completely removed the viable mold spores found on the fan housing and coil surfaces of the AC units. These results were the same whether the unit was operated continuously or as to temperature demand. It would be my considered opinion that PTAC would serve as an effective deterrent to mold growth on and in an AC unit, and would also be expected to produce a sustained and improved overall indoor air quality within the serviced areas.”

How we test

Real buildings, not just sealed chambers.

A sealed laboratory flatters any air technology: once contamination is removed, nothing new arrives. Occupied buildings are re-contaminated all day. We test in both, and label which is which.

Air sampling uses APACOR AirTrap XL, analysed by Sporecyte's AI platform at 96% accuracy, against 50 to 70% for the petri dish method.

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.
