The Unovent® home ventilation system is the most energy efficient technology on the market, delivering you a drier, warmer, healthier home. The unique ductless system is as much as 50 percent cheaper than other systems, yet is also more effective.

Inadequate ventilation is a key issue for New Zealanders. Poor air quality causes condensation on windows and moisture build up in drapes, carpets, furniture, walls and ceilings. An unhealthy, damp, musty smelling environment encourages rot, mould, mildew and dust mites – all potential causes of asthma, allergies and ill health. 

Designed by a Kiwi automation and control engineer for New Zealand conditions, Unovent® is suitable for new residential builds. Because it has no ducting it is perfect for renovations. The system is also effective in small offices and other light commercial premises.

Unovent® is a positive pressure ventilation system which takes fresh, filtered air, either from the roof space or by using a wall mounted option to draw from outside. Each Unovent® fan includes an industrial grade filter system which removes pollen and other harmful particles from the air. The system moves this air through one or more outlets into the selected rooms. This in turn gently pushes stale, moist air out through gaps under doors or around windows and through bathroom and kitchen vent systems.

The system’s simplicity is part of its genius. Because expensive componentry in the roof space is not required, both capital and operating costs are significantly reduced. Unovent® costs less than $1 a month to run. That makes it highly competitive with competing systems, which cost between $5 and $30 a month to operate.

Unovent® is fully automated, with no electronics to master and no adjustments required. It has a built-in temperature and humidity sensor controller, which has been optimised for New Zealand conditions. A safe 12-volt transformer plugged into a 240-volt socket is whisper-quiet; you won’t even know it’s there.

Unovent® delivers affordable air quality, providing New Zealand families with healthier homes in a convenient, cost-effective manner.
