DIY Donny, Formerly Known As Donald Sheridan

the resident DIY agony uncle for the Saturday Mirror & Sunday Mail recommends Passyfier Dehumidifier Vents (being non-mechanical) the solution for condensation control in Living Rooms, Dining Rooms & Bedrooms etc.

From October 2014 we are no longer supplying the PASS 75 nominal 100mm diameter (4”) core version of our Passyfier Dehumidifier Wall Vent Kits.

The PASS 100 nominal 125mm diameter (5”) core version is now our minimum standard which gives a vapour transmission of 1 litre over 24 hours and is available in low or high rise variants and a choice of 6 external colours.

The PASS 140 nominal 162mm diameter (6”) core version being our largest gives a vapour transmission of 1.4 litres over 24 hours and is available in low or high rise variants and white or brown external colours.
