Customer Reviews

Good for dry pickup, not so good for liquids
I'd suggest the cheaper, standard dry-only HEPA filter in place of this one, unless you occasionally suck up damp stuff or small amounts of liquid. This filter is not a good choice for wet applications. I also find that this filter is no easier to clean than any other reuseable cartridge filter. It's rinseable but that sounds better than it works in practice.

If you are faced with sucking up gallons of liquid, this filter doesn't work well. Unless the liquid is very clean, the filter clogs every few minutes. If I'm picking up a lot of liquid, I swap the good ol' foam sleeve back on.

This filter does work well for dry pickup. No more dusty exhaust, a huge improvement over the standard disc filters. However, it's no better than the standard HEPA filter in this regard.

Someone once suggested using an old-fashioned disc filter over the HEPA filter if you use it as a dust collector in a wood shop. I find this to be a very good combination. The disc filter takes out the bigger particles of sawdust, leaving the HEPA to do what it does best -- filter the very fine stuff. Otherwise, you will find yourself cleaning the HEPA a lot. Maybe you lose some suction with the two filters in place, but I really haven't noticed. The disc / HEPA combo would probably be nice for drywall debris and other stuff that has both big chuncks and fine dust.

OK WITH AN INSIDE BAG
It's a great filter if used with an inside bag. It will catch the fine dust. If you use it alone or with a garbage bag and a bag keeper, it will quickly fill up with stuff and have to be cleaned out. To clean it, you need to blow it with compressed air, making a huge cloud of dust. If you tap it as suggested you still get a huge mess of dust and it doesn't come clean. I tried it all three ways and decided to pay the price for the inside bag which catches most of the stuff being vacuumed.

It does the trick!
This is a good price on a good filter. You can get the advantage of hepa filtering for specialty clean up with out the big price tag.
