I'm a fan of this fan
4/5
The product works well and fits snugly into the space designed for it. Fixing it in was possible with just myself, though the instructions were fairly confusing to decipher.
It mentions on the product page that carbon filters aren't included, though it's pretty easy to miss (as I did) - the official supply of these from the manufacturer are really expensive compared to the more "universal" ones you get, though the fit will likely be better than what I managed with the cheaper filter type. This only matters if you're recirculating rather than extracting (a more expensive option due to the ducting required and the need to bore through your walls to outside.)
Once all was said and done though, the product looks and sounds good, not too loud but sounds powerful enough.
