Compared to previous models, this new filter is very good in both quality and usability. It is easy to install and take off. The good thing is after use you can just fold it and dump it as a standalone garbage bag like those black ones and it can last through light rains as well. I tend to use one bag for a long time before filling it up so I worry my bag could silently leak over the long period especially after sucking up nails or other hard/sharp thing. But with this bag you has less worries and it never leaked for me. Older versions gave me this troubles a couple times either too heavy and leak from mouth or got punctured in the body. But again it's good always keep an eye on the fullness. It filters drywall ashes very well and my hepa filter is still clean after 10 bags. The only drawback is the price is too high and I already spent more than the machine itself.
Drove all the way out to their warehouse because they don't have a store. They don't carry 20-gallon vacuum bags and they can't ship them to you--so don't buy the vacuum unless you want to go to **** to get your bags-and anything else- because the only thing they have in the store is appliances and SMALL vacuum bags for your home! Find a different vacuum that you can still obtain the bags since without a bag it is useless--just like Sears.
We need to comply with the new silica standards of OSHA and find that these, with the internal filter and exhaust filter are needed to meet the standard.
good quality perfect fit
