Designed to renew the air in every room of a home, our Purevent positive input ventilation system stands out with its smart technology and high-performance filtration.
It effectively prevents dampness, CO2, VOCs, and radon while preheating incoming air for enhanced thermal comfort. The positive input ventilation prevents moisture build-up, reduces unwanted air infiltration, and significantly improves indoor air quality.
This solution was designed specifically for professionals: The Purevent offers simple installation, hassle-free maintenance, and is compatible with a variety of residential projects, whether new constructions or renovations.
When paired with its smart sensors (optional), the Purevent becomes autonomous and highly efficient. The VMI sensors continuously monitor humidity levels and CO₂ concentration in the equipped rooms, automatically adjusting the ventilation flow to maintain optimal indoor air quality.
For control, the VMI+ app makes life easier for installers. It allows for easy configuration of the Purevent and streamlines maintenance.
Guided set-up, intuitive settings, simplified maintenance, everything is designed to save you time on site and provide your customers with a fully controlled experience from start to finish.
In the Purevent family, Purevent Hygro and Purevent Hygro+CO2 are certified by Eurovent, in a well-defined environment, for their ability to improve indoor air quality while optimising energy efficiency:


With the Hydro’R, the Purevent takes performance to the next level. The compact 17 cm Hydro’R module connects directly to the unit, transforming the ventilation system into a two-in-one solution: air quality plus thermal comfort.
By linking to an air/water heat pump, solar sensors, or a boiler, the Hydro’R can preheat the air in winter and cool it in summer. The result is a comfortable home all year round, with even air distribution throughout every room.
You don’t always need a heat pump to avoid overheating on the hottest days. By combining your Purevent positive input ventilation system with a Canadian well via a Bypass Smart, you can bring fresh air into your home during the summer.
Thanks to this innovative coupling solution, Purevent can benefit from two sources of fresh air instead of just one.
In both summer and winter, the Bypass Smart will always find the right combination of fresh and warm air sources to optimise occupant comfort.
