Matching your filters
No part number? A few measurements will do.
Most dust collector filters can be matched from the part number on the label. When the label is gone, the size, the media and how the filter mounts are usually enough to find a replacement.
- Bags: diameter, length, top style and media
- Cartridges: outside and inside diameter, length and end caps

Don't have the part number?
A clear photo may be enough to get started.
Photograph the old filter, its label, and the collector's nameplate, and add a tape-measure reading if you can. We'll review the photos and let you know what else is needed.
Start a requestCan you match the filters in my dust collector?
Usually, yes. Send the part number from the filter's label or from your collector's manual.
No part number? Send the size (bag diameter and length, or a cartridge's outside diameter, inside diameter and length), the media if it is printed on the label, and photos of the old filter and the collector's nameplate.
What should I include in a quote request?
The manufacturer and the complete part number (every letter, dash and suffix), or for a filter its size and media; the quantity; and the date you need it. A ship-to ZIP code helps with freight.
Photos of the nameplate or label are welcome, especially when a number is worn or hard to read.
Are you affiliated with the brands you quote?
No. Courtney Industrial Supply is an independent reseller. Unless a quote says otherwise, we are not affiliated with, appointed by, or endorsed by the manufacturers whose parts we quote.
Brand names and part numbers are used only to identify the part you need.
