Once Acorn tell me, where's the cheapest place to buy filters?

First, are you talking about charcoal filters, which you need only if
you have a recirculating hood; or the 'paper sheet' type which trap
grease, and which you need regardless of whether your hood recirculates
or extracts to the outside?

If it's the latter, you can get generic ones anywhere (Aldi - dare I
mention it - are particularly cheap) and cut them to size, rather than
buying expensive model-specific filters. The charcoal ones are usually
enclosed in plastic cassettes, which will be model-specific.
