Chip extractor filter bags?

[Doug71]

Can anyone explain to me the difference between chip extractor bags?

My Jet extractor came with one of the canvas type bags, when the suction drops, I take it off, clean it out and it's all good again.

Axminster sell an upgrade bag for £100

Dust spares sell the needle felt (is that the term?) type bags for about £15

Just wondered how the different prices are justified? Are the Dust Spares ones classed as disposable, do you just chuck them when clogged or are the Axi just massively overpriced?

Thanks, Doug

Cant help with the differences, but googling "Jet DC1100CK/DC1900A Fine Filter Bag" shows them at £53 here , or an old ebay listing at £42 here if that helps towards your last question
