The 750+

The most tested unit in the range, and the one behind our strongest live-environment results. Wall mount it in a room or fit it in-duct with no invasive works, then unplug it and take it with you to the next property.

Why this unit

Coverage: up to 1,000 sq ft
Mounting: Wall mounted, or fitted within AC ductwork
Best suited to: Bedrooms & nurseries
Villas & apartments
Hotel rooms & suites
Classrooms
Clinics & consulting rooms
Vehicles & transit cabins

The 750+ combines all three technologies in a single self-contained unit: an ODOGard®-coated HEPA+ filter for particulates and gas-phase odours, the ARC® advanced PCO cell producing hydroxyls, and a bi-polar ionisation module.

It is the unit we take into the hardest environments. Both of our 72-hour live trials in occupied, deliberately re-contaminated housing were run on a 750+ with no filter fitted, a deliberately conservative configuration, and still returned reductions of 96.4% and 95.9%.

Its lightweight, compact design means it can be wall mounted in a room or fitted within existing AC ductwork. In-duct installation is plug and play: no cutting into ducts, ceilings or walls, and no specialist engineering works. That makes it ideal for the rental market, where the unit can simply be unplugged and moved to the next property. A transit variant is also available for vehicles and enclosed cabins.

Inside The 750+

Three technologies, one compact unit.

All three technologies in one compact, self-contained unit: the ODOGard®-coated HEPA+ filter, the ARC® advanced PCO cell and the bi-polar ionisation module.

ARC®
Bi-Polar Ionisation
ODOGard® HEPA+ filter

ODOGard® coated HEPA+ filter
Captures and neutralises unwanted VOCs and odours rather than simply holding them in the media.
ARC® advanced PCO
Produces hydroxyls that help prevent mould, mildew and allergens from pets, pollen and smoke from establishing.
Bi-polar ionisation module
Creates a plasma of electrical charges that removes allergens and airborne pathogens from the breathing zone.
Wall mount or in-duct, plug and play
Sits in the room or within existing AC ductwork with no invasive works, and unplugs to move with you. Ideal for rental properties.

Test results

Published studies on this unit.

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

Live environment

Government housing · heavy existing contamination

96.4% reduction of Stachybotrys

Occupied apartment block

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.

Before After

Stachybotrys
34,013 → 1,867−94.5%
Aspergillus / Penicillium

Product: 750+ Wall Mount (no filter)
Technologies: PCO / O₃ / ODOGard®
Duration: 72 hours
Test space: Apartment block corridor & rooms
Administered by: Live field trial

Contamination was deliberately maintained throughout the trial rather than isolated.

Government housing · bathroom & ground floor

95.9% overall reduction

Occupied house

A second 72-hour live trial in an occupied property, again under continuous real-world contamination. Cladosporium, the most abundant airborne genus in most buildings, fell by more than 98%.

Laboratory

Sealed chamber · FDA Good Laboratory Practices

98.21% bioaerosol reduction of MS2

Aerosol deactivation of MS2

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.

Product: 750+ Wall Mount (no filter)
Technologies: PCO / O₃ / ODOGard®
Duration: 4 hours
Test space: 9.1′ × 9.1′ × 7.0′ sealed chamber (759 ft³)
Administered by: Aerosol Research & Engineering Laboratories

Conducted in compliance with FDA Good Laboratory Practices (GLP).

Field test

1,240 sq ft occupied workplace

97% reduction of surface mould and bacteria

Commercial office

Measured in real time over five days across a working office, covering airborne and surface contamination as well as gas-phase pollutants.

Measured reductions for Commercial office
Contaminant	Medium	Reduced
Mould spores	Surface	97.00%
Mould spores	Airborne	93.00%
Bacteria counts	Surface	97.50%
TVOC	Airborne	92.00%
HCHO (formaldehyde)	Airborne	94.00%

“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.”

The OverWatch

270 – 10,000 sq ft and up to 160,000 ft³

Built for volume. Where a space is measured in cubic feet rather than floor area (warehouses, plant rooms, sports halls, food handling), this is the unit that covers it.

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
We review what you've told us and come back within one working day.
2
A site assessment covering the space, the air handling system, and what's actually driving the problem.
3
A written specification and a fixed price, including the ongoing service interval.
