This is the "starter kit" to increase the filtration capability of the Nilfisk and Tellus GM80 and Nilfisk GS90 and Nilfisk GM90 Allergyvac. It comes complete with the extended handle, whereas the replacement filter kit 82147100 doesn't.
It's intended for asthma sufferers, and people who suffer from hay fever, although it's still a certified HEPA filter.
It was quite common for these to be used in hospitals for "infection control" and some weren't changed for very many years. Tut Tut!!
IT'S NOT FOR COMMERCIAL INDUSTRIAL USE, NOT APPROVED FOR HAZARDOUS DUST SUCH AS ASBESTOS.
According to EN 60335-2-69 The Terms "TYPE H" FILTRATION and HEPA FILTRATION are NOT INTERCHANGEABLE
The HEPA classification only considers the "efficiency of filtration" eg H10 H11 H12 H13 H14 U15 U17 NOT the SUITABILITY FOR USE with HAZARDOUS or COMBUSTIBLE dusts.
As they're light, maximise the saving on postage and buy some of the related parts below, such as dustbags and other filters or a new hose, a floor tool or other accessories.
At the moment standard postage within Australia is capped at a maximum of $20!
