80 mm / 3.15'' Inch Black Air Vent Cover - Round Ventilation Grille with Integrated Protective Mesh Screen - HVAC Vents for Bathroom, Home Office, Kitchen - Indoor & Outdoor Use

My shed got damp and mould due to a lack of ventilation. I fitted these high quality, great value vents at the end of the summer and no problems since. They allow good airflow whilst preventing ingress from pests. They're very good quality. Easily fitted with a hole saw and some adhesive. Highly recommend them. Now for a fresh lick of paint this spring!

Although, never needed in the end, it's well made and fit 100mm duct, very snugly. The mesh is not too small to get clogged with dust, but small enough to prevent insects getting in.

The garden shed was literally full of mould. On the ceiling, on the walls, on the shelves (that I had made new, sealed and painted precisely to avoid mould, as the first shelves had been consumed by the fungi beyond repair). I cleaned everything , I kid you not after 48 hours there was thick mould everywhere again. I bought high quality mould remover, treated the whole shed. A few weeks later mould was growing again. Enter: this pair of vents. Really easy to fit (drill a hole, push the vent in with a bit of glue around it, caulk on the other side, done). Result: the mould isn't growing back, the condensation is gone, the smell is gone, I can store stuff in the shed. The vents are exactly the size advertised, the two of them (one down one wall, the other up the opposite wall) make a nice cleansing air current. They are sturdy, inexpensive, arrived swiftly, don't let any beasties in, create perfect passive ventilation, and my kids even think they look cool. Can't recommend enough.

Haven't tried it yet but it looks fine I have used something similar before and this set seems to be fit for purpose.

Good quality vents.
