Rated 5.0 out of 5.0 by This filter has excellent filtering capability. I have two of these filters I use when doing my wood working projects. They are excellent filters. I change them and wash them and have had one of my filters for over 5 years. November 24, 2014

Rated 5.0 out of 5.0 by This lil filter keeps my allergies at bay! Good quality and it really keeps the particulates from entering my super allergic nose! Works great! June 17, 2015
Rated 5.0 out of 5.0 by Good filter for cleaning pellet stove ash I bought the Ridgid shop vac to use for cleaning my pellet stove of ashes after ruining a regular HEPA filter house vac cleaning it. I wasn't sure if the blue filter for fine dust wold be sufficient or if I needed to purchase the more expensive HEPA filter. This worked and doesn't release any soot particles into the air when vacuuming that I have seen or noticed. It should be noted that I need to completely dust the room where the stove is located and then try again to get a better feel but I have this vac/filter combo 3 times now and it is not requiring any extra dusting that I can tell so far. I did notice a reduced suction after using it in my 4 gallon vac but I don't mind cleaning the filter once every third use. January 20, 2015

Rated 5.0 out of 5.0 by Great. Works well and easily inserted and removed for cleaning. January 27, 2015
Rated 4.0 out of 5.0 by 4 gal Rigid vac filter The filter works very well to filter out dust and lint but lacks "rigidness". At the first sign of moisture, even a little, the filter gets twisted and weak. It could use a few stabilizer bars along the core from top to bottom to prevent collapsing and twisting. May 28, 2006
