Positive Input Ventilation
A ventilation system that improve indoor air quality & eliminates condensation. 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. There are healthy benefits for asthma and respiratory sufferers.
Why improve your ventilation?
What is PIV Ventilation?
It is a concept to deliver fresh filtered 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 90% 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.
We inhale and exhale approximately 20,000 times a day. By sealing up our homes we are breathing in a viral soup of many contaminants. PIV insulation deliveries fresh filtered air 24 hours day.
Waking up to streaming windows? damp and condensation is a real issue in British homes. The PIV unit circulates fresh filtered air into your property encouraging movement of air and reducing excess moisture which can cause condensation and damp.
50% of all illnesses are either caused or aggravated by poor indoor air quality. PIV insulation lowers humidity levels, and reduces dust mites, which can provide a signiﬁcant improvement in reducing one of the major triggers for asthma suﬀerers.
More Reasons To Buy PIV
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 breathe 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.
Frequently Asked Questions About PIV
Yes. There will be gaps around the edges of the doors, which will enable the fresh air to flow throughout the property.
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.
No, our range of Positive Input Ventilation PIV run ‘whisper-quiet’.
Our range 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
