Filter Kits

Filter Kits for Harbor Freight, Jet, Delta, Grizzly, Shop Fox, General, Rikon, Kufo, Rockler, Powermatic, Wen, and Penn State.

For over 18 years, our 35-Series Filters have been built specifically as upgrade replacements for the balloon bags used on hobby and small shop dust collectors. With tens of thousands of units shipped, we have developed a wealth of experience upgrading these systems.

Upon startup with a pleated cartridge filter, the first thing you will notice is a huge increase in airflow, as compared to the original bag arrangement. This is due to the large surface area of the cartridge filter. Remember, doubling the surface area of a filter results in a four-fold decrease in pressure. Stock bags offer about 35 sq. ft. of area, so increasing to a 222 sq. ft. cartridge makes a big difference!

In addition to the increased flow, the filtration efficiency of your system is also improved. This is partially due to the increase in surface area, but is mainly due to the improved performance of the filter media. Our standard 35A274BLOL filter is rated 99.99% efficient at 0.5 microns after an initial break-in period. And the 35C222NANO, featuring the next generation of Nanofiber Laminate filter media, can achieve 99.999%. These NANO filters carry the MERV 15 rating.

Our most recent addition to this product line is the 35B222NANO, which includes a removable end cap. The removable end cap can be useful when filtering fibrous dust and lint, by providing easy access to the inside of the filter, without having to remove the entire filter for cleaning. In addition, the 35B can be stacked underneath the 35C, doubling the filter capacity of your system. This technique is used for extremely tough applications, with extreme dust loads.
