Positive Input Ventilation Units

PIV units (for short) are a great piece of equipment to eliminate

damp & condensation building up in your home causing untold

amounts of issues. In a nutshell they work by introducing fresh,

filtered air into your home at a continuous rate, encouraging

the movement of air from inside to outside the property.

The PIV unit is mounted in the loft where it draws air through specially-designed filters before inputting into your home at ceiling level. The units filters remove pollutants such as Radon gas, pollen, and traffic fumes delivering better indoor air quality. Overall this makes for a healthier living environment, in particular for allergy sufferers and those with asthma.
