In the loft cavity, mark the centre point between two joists, and drill a hole in the centre point. 3. Using the diffuser template provided, line up the centre point, and mark out the section to be cut out of the ceiling. 4. Cut out the section of ceiling ready for the diffuser, then fit the diffuser into the hole, and secure with the screws and plasterboard plugs provided. 5.

### ⭐⭐⭐⭐⭐ This is a game changer !!!
*by A***R on 12 April 2025*

### ⭐⭐⭐⭐⭐ Game Changer
*by B***N on 14 September 2024*

We live in a 200 year old listed building. The cost to replace the windows (single sash) would be astronomical. Every morning in the winter I had to use a Karcher Window Vac to remove the water from all the steamed up windows . I came across this PIV on YouTube and was sceptical to say the least. I bought it anyway. The unit is huge but not heavy , just bulky . I installed it in about an hour . The next morning when I got up every window in the house was crystal clear. I'm absolutely amazed and dumbstruck how this PIV unit works. If your house suffers from damp/moisture I highly recommend getting this unit. I live in the far north of Scotland so bought the one with the heater but not sure about the difference between using the non heater version .
