Product review (4 stars): Right filter for my fan
This is the only filter I can find in Amazon that fits right into my fan slot and replace the old filter which looks identical to this filter. But my fan is a ducted extract fan. This fan seems for non-ducted fan only. I have asked a question here but the answers don't really help much. It may be possible the plumber who installed my extract fan made a mistake. Now I have to stick to this filter. More filtration with thicker media is not a bad thing. But I may have to replace it more frequently.
