Differences between a Henry Hoover and a Nuvak Hoover?

[zenonithus]

Henry uses TriTex filtration and Nuvak uses permatex filtration. Is one better for industrial cleaning jobs? ie cleaning lead paint so the dust doesn't escape out the hoover?

I suspect neither manufacturer will endorse their standard vac for "toxic" dust, certainly Numatic freak out if asbestos is mentioned they sell the HZQ vac for hazardous waste around £500 a pop!
Having said that I have used the Henry for general work (not toxic) and the new cloth type bags are much better than the old paper ones, I hardly ever need to clean the internal cloth filter but before I often found it very dusty with the original paper bags.

No asbestos that I know of it's mainly for hoovering up the bits of scraped off paint and dust that may or may not be lead based, though assuming it is. I'm using a standard henry with hepa-flow cloth bags, though not sure if it's worth getting a Nuvac model as it uses the different filtration system, permatex filtration which may or may not be better for trapping the dust. Yeah the HZQ Hazardous Waste Hepa Filtration Vacs cost a fair bit so not sure what the best solution is :-\
