Now I have bought the charcoal filters it appears to be working perfectly. I was aware that the filters are not included but could I suggest AO put a list of sockists in with packaging making the stressful process of installing the extractor ( novice ) a little less fraught.

It's working well so far. Time will tell for reliability. We bought it for the extra strength of the fan versus others in the same price bracket and haven't been disappointed. It's not as noisy as some of the other reviews had suggested, but it's certainly not silent either. Worth it for condensation-free windows though! Pretty easy to instal, although be careful because some of the sheet metal parts have very sharp edges and can easily cut careless fingers. It would have been nice to have received it with a plug though.

I replaced my old canopy hood because it was just too inefficient. This was the only one of a compatible size and, despite the limitations of a small aperture under my kitchen cabinets, it does a better job. I ordered the charcoal filters online as they're readily available and I'm happy that I can wash the grease filter. A bit noisier than expected but very happy to to put with it because it does a good job for such a small size.
