What is PIV Ventilation?
It is a concept to deliver fresh fltered air into a property at a continuous rate. 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 between 45-60%*. This signifcantly 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
Why Ventilate your home?
The eﬀect of not having good quality air in the home is dramatic. The average person spends 0% of their time indoors and 70% of this time is spent in their own home. The indoor living environment is therefore crucial to the health of the occupants. Modern housing has become increasingly energy conscious. In order to save energy we have blocked chimneys, insulated, draught proofed, double glazed etc and progressively sealed our homes from an essential supply of fresh air. This may save energy and make our homes more comfortable, however we pay the penalty by living in and breathing in this stale, contaminated, humid air for 70% of the time.

How Positive Input Ventilation PIV Works?
Positive Input Ventilation (PIV) systems create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout a property. PIV Systems work by ensuring the movement of air from inside a property to outside from a unit. The PIV unit circulates fresh filtered air into the property at a continuous rate, encouraging movement of air and reducing excess moisture which can cause condensation and damp.Positive Input Ventilation (PIV) systems help your whole home to breath and improve the indoor air quality by gently circulating fresh, filtered clean air into your property at a continuous rate. Our range of Positive Input Ventilation (PIV) units help to reduce moisture trapped inside your home which if left unmanaged can cause condensation problems and lead to mould growth.

Why Ventilate - Condensation Problems
If condensation occurs over a prolonged period of time, other signs will start to appear such as damp patches on walls, peeling wallpaper and ultimately black mould growth. The best solution for condensation is proper ventilation, in order to vent condensation your home needs to have an adequate air flow and kept at a good temperature. When a room gets to a certain temperature, humidity gathers creating moisture in the air. If this excess moisture is not ventilated it will cause condensation. Our PIV systems will reduce condensation and improve your indoor air quality, whilst having a positive effect on your health and your home.
Why ventilate - mould problems?
1 in 5 UK homes suffer from mould and condensation problems. Unless the problem is dealt with professionally it will come back to haunt you time and time again. Apart from being unsightly and ruining your decor, there is growing evidence to suggest that it is also bad for your health. It can cause headaches, breathing difficulties as well as nausea and fatigue. What’s more, mould is a recognised allergen and irritant, it has also been identified as a trigger for respiratory problems such as asthma. Our PIV systems will reduce mould problems and improve your indoor air quality, whilst having a positive effect on your health and your home.
Why ventilate - Asthma & Allergies?
As most asthma or allergy sufferers will know, the common house dust mite can play a major part in aggravating their symptoms and high levels of humidity in the home is the perfect breeding ground for dust mites. Our products can help alleviate the symptoms of asthma and dust mite allergies by reducing the triggers. Our ventilation systems can provide continuous all year-round ventilation to reduce humidity levels within the home. By controlling these to between 45-60%, dust mites are less able to breed and the population will diminish, helping asthma and dust mite sufferers to breathe more easily.
Why ventilate - Improve Indoor Air Quality?
There are as many as 900 toxins polluting the air inside our homes, so it is important to ensure you take measures to improve the indoor air quality. The modern home has become increasingly energy conscious. In order to save energy we have blocked chimneys, insulated, draught proofed, double glazed and progressively sealed our homes from an essential supply of fresh air.
Why Ventilate - No Need to Open Windows?
To reduce humidity and condensation during the heating season, significant energy loss occurs by opening windows. By installing an PIV Ventilation system and providing fresh filtered air to the home humid air is displaced without opening windows and thus making significant savings to your heating bills in addition to improving building security.
Cost-effective Ventilation for New Build Projects
Positive Input Ventilation is a popular method of ventilating new build homes. This ventilation strategy is supported by a BBA certificate and recognised as an alternative method within building regulations. Our range of -Eco friendly PIC systems are extremely cost-effective ventilation solution that offers unique benefits when installing and commission the units. PIV is also recognised as a method of reducing harmful levels of radon gas levels in affected areas.
Does Positive Input Ventilation PIV work if I have closed doors in the house?
Yes. There will be gaps around the edges of the doors, which will enable the fresh air to flow throughout the property.
Is the air cold circulated around my house?
The air being brought into the property does come from outside, however warm air lost at ceiling level will be regained via the diffuser. You may notice the air movement, but this is very gentle
Will I hear positive Input Ventilation PIV unit running?
No, our range of Positive Input Ventilation PIV run 'whisper-quiet'.
What maintenance is required?
Our of positive Input Ventilation PIV requires very little attention. Filters are replaced every five years. For optimum performance, the filter should be kept clean and clear. When the filter becomes dirty, the unit does not input as much air into the home, creating the opportunity for condensation and musty smells to become evident. This will be a signal that you need to have the filter checked and replaced/cleaned as necessary
