## Questions & Answers

**Q: Will it reduce the airflow with the harbor freight (central machinery) 2 hp dust collector, which comes with a 5 micron bag?**
A: I have no positive way to tell but I can say I can see no visible reduction from the dust collection when connected to my tools (planer or table saw). I am well pleased with the bag. It is stiffer and thicker than original. Fit was pretty much like original. I am however, using the larger impeller on my dust collector (Wen part / not Rikon - much cheaper and availible) that did increase the suction on my unit.

**Q: will this bag fit a shopfox w1727?**
A: measure the diameter where the bag fits on your shop fox. 21" is the diameter of the bag. it was a little loose on my HF DC but the band clamp sealed it good

**Q: Has this been 3rd party tested?**
A: Bagged dust collectors spew dust!
This bag cuts the spew down.

**Q: Will the 1 micron bag fit over the Jet canister filter?**
A: its 21" diameter 31" long. i dont think bags are supposed to go over canister filters

## Customer Reviews

### ⭐⭐⭐⭐⭐ Hold Up Well!
*by T***K on February 17, 2025*

This filter fits my Harbor Freight Central Machinery, 35-gallon dust collector. It is thick and well-made. I can't attest to how small dust particles it can filter out, but it seems to work well in my shop. It is easy to install and can be pressed down when not in use to save space.

### ⭐⭐⭐⭐⭐ Great way to get better filtering
*by F***K on February 7, 2025*

Arrived in 2 days I think ... I just purchased a 2 hp Harbor Freight (5 micron) dust collector to replace my 1 hp Grizzly. I was concerned about the fit and how performance might be affected going from 5 microns to 1 micron filtering. Fit was fine. The bag seems much thicker than the standard HF bag. Good quality too.re: CFM / suction, I did a very unscientific test by seeing how effective an open, horizontal pipe would hold a package of sandpaper. With the 5 cfm bag, it would barely hold the package with 3 sheets. With the 1 micron it also barely held the same package of 3 sheets. Neither would hold 4 sheets and easily held 2 sheets. So, for me, not a lot of difference in suction / cfm. I was happy with that. How's that for hillbilly testing? ;-) See photos.

### ⭐⭐⭐⭐⭐ Tight fit
*by D***R on September 9, 2025*

While it will fit on a HF 2hp dust collector, the bag is thicker than the stock 5 mil bag so the metal band holding it on will be stretched to the max and likely need a pliers to stretch the spring. It works great.
