VentPlus for workplaces
Modern offices and high-occupancy spaces — conference halls, meeting rooms, restaurants, bars, banquet halls — are sealed for thermal efficiency and noise insulation, and that seal lets CO2 from human respiration accumulate silently. As levels rise they progressively cause reduced alertness, yawning, drowsiness, a stuffy feeling, significant cognitive impairment, breathing discomfort, fatigue, headache and nausea — yet remain completely undetected.
VentPlus CO2 monitor & controller solves this automatically, without any manual intervention: decisions, meetings and staff comfort all improve when the air does.

The VentPlus solution
Indoor air quality should never be left to guesswork or inconsistent manual intervention. VentPlus pairs a precise CO2 monitor with a relay to operate your fresh air / exhaust fan / ventilation system — automatically. Plug and play installation — no electrician needed.
Real-time CO2 tracking in every monitored space.
Fresh-air intake starts the moment your set threshold — say 1,500 ppm — is crossed. Mid-meeting, without interruption.
Ventilation shuts down once healthy air — say 1,200 ppm — is restored. Demand controlled ventilation means HVAC runs only when needed, keeping air-conditioning costs under control.
Track your office air quality live from your phone, tablet or laptop. The online VentPlus dashboard plots real-time and historical CO2 levels for every monitored space, so facilities and admin teams can see exactly when meeting rooms and open-plan floors get stuffy. In the chart below, the dotted line shows the estimated CO2 without VentPlus — climbing well past healthy limits as the room fills up — while with the VentPlus CO2 monitor & controller installed, ventilation kicks in automatically and air quality stays 'Good' through the working day. Temperature and relative humidity are graphed alongside CO2, which shows whether a room is stuffy, overheated or both, and the Excel download carries all three for facility reports.

This isn't a wellness slogan. Peer-reviewed research consistently shows that cutting indoor CO2 back to fresh-air levels — exactly what VentPlus does automatically — measurably sharpens how people think and work.
Harvard researchers found that doubling office ventilation lifted workers' cognitive scores by 8% — worth an estimated $6,500 per employee, per year in productivity, at under $40/person in energy.
MacNaughton et al. 2015, Int. J. Environ. Res. Public HealthIn a controlled study, cognitive scores were up to 101% higher in low-CO2, well-ventilated air than in a conventional office — with the largest gains in strategy and crisis response.
Allen et al. 2016, Environ. Health Perspect.A meta-analysis pooling 47 experiments and 3,679 people found better ventilation raised task performance by 13.7% and cut error rates by 16% — weight-of-evidence across many studies.
