Blauberg Condensation Control Passive Wall Intake Vent Grille Cover 100mm (4 inch) Spigot White Mould Control

Looks good and works well

Used this vent as a far more attractive alternative to the one previously installed. It looks great on the wall and importantly still provides the circulation of air needed to manage condensation in an older style property. Its very easy to install, literally taking a few minutes, and the fact is has a filter / insect screen is great. It does help to mitigate some of the potential noise on windy days too. As with many of the other reviews, I didn't install the pull cords and just left the 'switch/ slider' on the bottom to adjust the opening if needed.

Looks good In the rooms

Replaced vent with flaps, so nice and quiet. Easy to fit. Can be closed off to stop draughts.

The vent grille cover looks very pleasing and does by no means feel flimsy. I liked, that the cover is a little bigger than my old vent outlet as this allowed to fix it properly as opposed to the old cover where the screw holes were very close to the spigot, to close for proper fixing.It does come with 4 no. screws, 4 no. 5mm wall plugs, 2 no. bits of string (pull cord) and 2 plastic handles. The strings, along with the plastic handles, can be attached in order to open and close the vent, in case the vent outlet is to high to reach the slider. That brings us to the one point I was a little worried. Closing the vent, without the filter and the cover fitted, caused the shutters to open a little bit at the lightest vibration. Enough to get a notable cold draught in. Hence I fitted the pull cord on the closing side, to be able to shut if needed.Luckily, once the filter had been put on and the cover was fitted, there was no need to frequently making sure, that the shutter is closed. Initial checks over the first days revealed, that the problem did not occur, once fully fitted.All in all, it looks even better than on the product picture and does the job, perfect. Due to the slightly curved edges it hides tolerances to an extend, which is a benefit, as the screw holes do not allow for much adjustment.

Looks wise it's nice and simplistic. Not a fan of the slider being fixed at the bottom as when you open it to clean the filter its a pain to fix the slider back on as you can't see where to secure it so I now have it on sideways. Adjusting can be stiff.As for the humidity issues it claims to address thats a fail. Even set to only be open half way the rooms get more humid despite windows and doors being shut. Huymidity reading was 59% when I went to bed and 69% when I woke up. Sure it'll get more humid as moist come out as we breathe but not that much, it did rain throughout the night. I then put in a small dehumidifier and let it run for 3 hours. Room is now at 73% humidity and I got almost 200ml from the demuidify in that time. The only source of moisture to enter the room is through this vent

Very good quality, solid item.

Easy to fit
