The Benefits of ‘Input’ Ventilation

For your home, health and lifestyle

What is PIV?

Positive Input Ventilation

PIV IS A CONCEPT TO DELIVER FRESH FILTERED AIR INTO A PROPERTY AT A CONTINUOUS RATE

Did you know…
→ Thousands of homes across Ireland are benefitting from having a PIV unit installed
→ It’s the second most popular method of ventilating homes after extract fans

The reason is…

In addition to the 112 pints of moisture that an average family produces per week through cooking, bathing, ironing etc., a concoction of other contaminants is present in the air within our homes.
These can have a detrimental effect on the fabric of our homes and the health of our families. With improved building features in our homes, such as cavity wall insulation, double glazing and draught proofing, ‘natural ventilation’ is prohibited. Stale, contaminated air is trapped causing streaming windows, which ultimately leads to musty smells, dampness and mould growth.

The solution…

The solution is Positive Input Ventilation (PIV). The EnviroVent positive ventilation units are sophisticated whole home ventilation and condensation control units. By drawing in fresh, filtered and clean air from outside, the units gently ventilate the home from a central position on a landing in a house or the central hallway in a flat or bungalow.

Moisture laden air is diluted, displaced and replaced to control humidity levels around 55%. This significantly reduces or eliminates surface condensation, the main cause for mould growth. With lower humidity levels, dust mite populations are also substantially reduced to provide a significant improvement in the health of asthma sufferers and general indoor air quality. Positive Input Ventilation is also available for flats and apartments.

 

How it works

Shortly after the unit is installed…

The unit gently ventilates the home with fresh air. Air is pushed back down into the house and redistributed. Humidity is replaced and diluted to leave a healthy, fresh and clean environment to live in.

 

 

 

 

 

The house is now free of contaminants…

The units transform a stagnant, stale atmosphere into a fresh, healthy and condensation free environment.
