Manrose are a giant name in extractor fans. This is not their budget offering, but it’s still less than twenty quid. It doesn’t have the amazing design of the Icon ECO 15, but it looks perfectly inoffensive.

When we did the flow rate test, we were pleasantly surprised. Even with the gravity vent backdraft preventer installed, it registered 14 l/s on our flow rate test. With the standard cavity wall setup we tested, it is compliant with Part F.  You’ll need to do your own flow rate test to see if your installation is adequate.

It’s pretty noisy, though, so our quest for a good budget fan option continues!
