What is PIV & How Does it Work?

Positive Input Ventilation (PIV) system is a cost-effective, low-maintenance way to reduce condensation. Stop black mould. But most importantly improve air quality. With better house ventilation in your home, a PIV unit gently pushes out stale, damp air. Then replace it with fresh, filtered air. All day, every day.

No more wet windows. No more musty smells. Just cleaner air for you and your family.

Signs Your Home Needs Better Ventilation

Many homeowners don't realise their property has ventilation issues until problems become serious. Common warning signs include: water droplets forming on windows and mirrors, musty or stale odours that won't go away, black spots appearing on walls or ceilings, and clothes or soft furnishings feeling damp.

You might also notice increased allergy symptoms, disturbed sleep, or that your home feels stuffy even with windows open. These are all indicators that your home's natural ventilation isn't sufficient.

A PIV system addresses these issues at source, creating a healthier living environment for you and your family whilst protecting your property investment.
