VentPlus for workplaces

Alert staff.
Enhanced productivity

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

An essential gadget in your office,
and all other enclosed spaces where people gather

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.

1

Continuous monitoring

Real-time CO2 tracking in every monitored space.

2

Automatic activation

Fresh-air intake starts the moment your set threshold — say 1,500 ppm — is crossed. Mid-meeting, without interruption.

3

Energy optimization

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.

Real-Time and Historical CO2 Monitoring
From Anywhere

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.

Proven results

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.

+8%
Cognitive performance

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.

+101%
Higher-order thinking

In 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.

+13.7%
Work-task output

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.

Common questions

FAQs for offices

In a typical meeting room with 8–12 occupants, CO2 starting at 600–800 ppm can reach 2,500 ppm within 60–90 minutes. Cognitive-function scores fall about 21% for every 400 ppm rise (Allen et al., 2016, Environmental Health Perspectives), and by 2,500 ppm most measures of decision-making have dropped to levels researchers call dysfunctional (Satish et al., 2012, Lawrence Berkeley National Laboratory).
According to ASHRAE Standard 62.1 and WHO guidelines, CO2 should ideally stay between 600 and 1,000 ppm. Above 1,500 ppm indicates poor ventilation and causes fatigue, drowsiness, and reduced concentration — directly impacting meeting efficiency and employee output.
VentPlus continuously monitors CO2 and switches your fresh-air or exhaust fan on automatically when CO2 crosses your set threshold. Once healthy air is restored, the fan switches off. No manual intervention needed.
Yes. VentPlus is used across high-occupancy spaces including gyms, fitness studios, schools, classrooms, restaurants, bars, and banquet halls — anywhere human respiration causes CO2 to accumulate rapidly.
No. VentPlus is completely plug-and-play. Simply plug your exhaust or fresh-air fan into the AC socket on the unit, set your CO2 thresholds using the front-panel buttons, and it starts working immediately. No wiring or electrician required.
