What Can You Do About Condensation and Mould?

---

Positive Input Ventilation creates a healthy environment by pumping and circulating fresh filtered air into a house, forcing stale air out of the gaps and cracks in the fabric of the building. 

The PIV unit is installed in the loft area, and a distribution diffuser mounted in the ceiling in the room below. The continual supply and slight positive pressure result in the air in the property being continually diluted, displaced and replaced to create a healthier indoor air quality. 

On average, Positive Input Ventilation systems cost between £1,200 - £1,800 including installation, however, there are some higher cost models available with improved performance. 

Once installed, the running costs are relatively low as the system has low energy requirements. You can expect running a PIV unit to cost 1p-2p in electricity a day.

Positive Input Ventilation is a cost-effective solution to a number of problems caused by excessive moisture in the home, including:

• Condensation on windows
• Damp and mould

A PIV unit can also help improve indoor air quality, helping to reduce odours, Volatile Organic Compounds and pollutants that enter the house. It can also reduce humidity by ensuring a fresh flow of air into the property. 

PIV is clinically proven to help reduce dust mite allergens which can cause asthma and affect allergy sufferers.
