Review: Great way to get better filtering - 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. Review: Hold Up Well! - 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. ## Features - INCLUDES: (1) Heavy Duty Dust Collection Bag - APPLICATION: This 1 micron filter bag is used to control and trap up to 99% of fine dust particles created when utilizing sanding, table saw and other woodworking equipment - DESIGN: Made from ultra-thick material, these reusable high grade collection bags were crafted for long term use, while making a huge difference for keeping your shop clean, and without a reduction of air flow - SIZE: Each dust bag measures approximately 31 inches high and 19-5/8 inches in diameter - COMPATIBILITY: Designed to work as a top dust filter bag for most dust collector systems such as JET, Grizzly, Shop Fox, Harbor Freight, and Wen (Works with the models between 18" and 20") ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BD83FTBX | | Best Sellers Rank | #68,653 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #109 in Vacuum & Dust Collector Bags | | Brand Name | POWERTEC | | Color | White | | Compatible Devices | Dust collector modles between 18" and 20" | | Customer Reviews | 4.6 4.6 out of 5 stars (220) | | Global Trade Identification Number | 00843441116028 | | Included Components | INCLUDES: (1) Heavy Duty Dust Collection Bag | | Item Depth | Standard | | Item Dimensions | 15 x 12 x 4 inches | | Item Type Name | POWERTEC 70333 Dust Collector Bag, 21" x 31", 1 Micron Filter | | Item Weight | 2.07 Pounds | | Manufacturer | POWERTEC | | Material Type | Cotton | | Number of Items | 1 | | Other Special Features of the Product | Easy Installation, Easy Removal | | UPC | 843441116028 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** POWERTEC - **Color:** White - **Compatible Devices:** Dust collector modles between 18" and 20" - **Material:** Cotton - **Number of Items:** 1 ## Images ![POWERTEC 70333 Dust Collector Bag, 21" x 31", 1 Micron Filter, For JET, Grizzly, Shop Fox, Wen, Harbor Freight, and POWERTEC DC-1512 - Image 1](https://m.media-amazon.com/images/I/41-PalONA1L.jpg) ## Available Options This product comes in different **Style** options. ## 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 ### ⭐⭐⭐⭐⭐ Great way to get better filtering *by F***K on February 7, 2025* Arrived in 2 days I think ...

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. ### ⭐⭐⭐⭐⭐ Improvement over the typical dust collector bag *by M***E on March 20, 2024* I purchased a Harbor Freight dust collector for my shop, and while it does a good job of keeping dust down, the really small stuff would get through the bag. Turning on the collector sent a large puff of fine dust into the air. This bag has really minimized the fine dust. It was easy to install - it's just a bit larger than the original one, but only in height - the circumference is a perfect match. This bag is stiffer, so it stands up - which is good since the bag hook on the collector is kind of useless with the height of this bag. I may add a shop air filter as well to really clean it up, but this has made a great improvement. ## Frequently Bought Together - POWERTEC 70333 Dust Collector Bag, 21" x 31", 1 Micron Filter, For JET, Grizzly, Shop Fox, Wen, Harbor Freight, and POWERTEC DC-1512 - Harbor Freight Dust Collector Bags for Central Machinery 35 and 70 Gallon Dust Collector | Made in USA - POWERTEC 71735 19-1/8 Inch Band Clamp for Dust Collector, Fits JET, Grizzly, Shop Fox, Wen, Harbor Freight, and POWERTEC DC-1512 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/470600140-powertec-70333-dust-collector-bag-21-x-31-1-micron](https://www.desertcart.us/products/470600140-powertec-70333-dust-collector-bag-21-x-31-1-micron) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-12*
