90 cm hob extractor fan - 2 filters + glass dome, or 3 filters?

Jan 01, 2026 1 Replies

Still looking for a replacement extractor for the kitchen.



The switch panel on our current one is almost inoperable and getting it fixed would be almost the same cost as getting a new one. [That is, getting someone to do it as my hands and various other joints are banjaxed.]



The options for a 90 cm extractor to fit over the 5 burner hob are either



2 filters and a glass curved canopy to lead the smoke into the centre, or a flat 3 filter fan.

So far we have had 2 filters and glass.



Now I am wondering which might be more effective.



Personal experience more than welcome.



Cheers

I am having exactly the same problem. My current extractor is a 45 deg Westinghouse model venting into a disused chimney, which has been in place for ~20 years. I see that it is still available at Screwfix. I just need to get some professional help for the best option.
