** Filtration **
As I've already stated the Proaction comes with washable filters but they are not HEPA identified which means at best the filters will retain most odours whereas strong odours do eventually come through such as pet hair odour. The fact that both filters are washable though means less cost and worrying about where to find replacements. Both filters are white in colour and the main exhaust filter (at the top by the motor) has a handy flip out grille door where the main filter can be picked out. In all instances however, both the filters are easy to spot, take out and install again. In terms of stages this vacuum has 4 stages of filtration including the main filter which fits into the bin; in this respect it is no better than other rivals on the market.
