Dust Collectors
High-performance replacement filters engineered for industrial dust collection systems used to control airborne dust and particulate emissions. Commonly applied in manufacturing, woodworking, metalworking, and material-handling environments, these filters help maintain clean air, protect equipment, and support regulatory compliance.
Send us the make and model of your dust collector, mist collector or air cleaner and we'll tell you which filters it takes, with price and availability. Or email info@rx4cleanair.com.
Replacement dust collector filters, matched to your machine
Rx4CleanAir stocks replacement cartridge filters, bag filters and HEPA after-filters for the industrial dust collectors we see most in the field: Donaldson Torit Downflo, DFO, DFT and T-2000; Camfil Farr Gold Series GS-8 through GS-24; Airflow Systems DC, DCH, DCB, DS-1 and V-Series; Amtech AT, ATV, AV and ATH; Robovent DFM and Fusion Vortex; Plymovent B and BM Series; Air King M75; IVEC GVSC; Filter 1 PFV; and FumeVac FV-500-20. Pick your collector above to see every filter that fits it, or use the cross reference below if you have the OEM part number in hand.
Genuine Airflow Systems filters are the OEM parts; the rest are non-OEM replacements built to the original filter's dimensions, end style, gasket and media class, and each listing names the OEM part numbers it replaces. In-stock orders placed by noon Central ship the same business day; UPS Ground for a few cartridges, LTL freight for pallet quantities, both quoted at checkout.
Three ways to find the right filter
- Part number. It is printed on the end cap or label of the filter you are taking out. Search it in the box at the top of the page; our listings carry the OEM number and its common variants.
- Machine make and model. Every collector above links to the filters that fit it, including the HEPA after-filter and hose kit where the machine uses one.
- Measurements. Outside diameter, inside diameter and length, plus the end style (open/open or open/closed) and the media on the old filter. Send those through the chat button or a quote request and we will confirm the match before you order.
Filter types used in dust collectors
- Cartridge filters are the pleated cylinders in Downflo, DFO, Gold Series, AT/ATV, DFM, Fusion Vortex and most compact collectors. Two end styles: open/open (the cartridge slides over a yoke or sits between two seals) and open/closed (one end capped). Media choices below.
- Bag filters hang in older baghouse-style units and in Air King M75 and Trion collectors: 24 x 24 x 22 inch pocket bags in 65% and 95% (MERV 15) grades.
- HEPA after-filters sit downstream of the primary filter on Airflow Systems DC and DCH units and on any collector that returns air to the shop.
- Box filters and pre-filters for DS-1 downdraft and similar units, and the Vibra-Pulse hose kit for Airflow Systems DC, DCH and DCB pulse-cleaning systems.
Which media?
| Media | Use it for | Rating |
|---|---|---|
| 80/20 cellulose-polyester | General dry dust, moderate loads, lowest cost per filter | MERV 11 |
| Nanofiber (Ultra-Web-type) | Fine or sticky dust, high loads, longest life: the dust cake forms on the surface and pulses off, so pressure drop stays low | MERV 15 |
| Nanofiber FR | Metalworking, grinding, sparks and any process with a fire-retardant media requirement | MERV 15, flame-retardant |
| Melt-blown and spunbond | Washable or high-moisture applications; ask before switching from a cellulose blend | Varies by filter |

Frequently asked questions
- How often should dust collector filters be replaced?
- Go by the pressure gauge, not the calendar. When the differential pressure across the filters no longer drops back after a pulse-clean cycle, or climbs past the collector's rated range, the media is blinded and it is time to change. Most operations change cartridges somewhere between one and two years, but heavy dust loads, hygroscopic or oily dust, and high humidity all shorten that. Torn media, a failed gasket or dust downstream of the filters means replace now.
- Will a non-OEM filter fit my Donaldson Torit, Camfil Farr or Robovent collector?
- Yes, when the dimensions, end caps, gasket and media class match the original, which is how our replacements are built. Each listing states the OEM part numbers it replaces and the machines it fits. If a cross-referenced filter does not fit, our fit guarantee covers it: return it within 30 days with no restocking fee.
- 80/20 cellulose-polyester or nanofiber: which cartridge should I buy?
- 80/20 blend is the economical choice for general dry dust at moderate loads (MERV 11). Nanofiber media loads on the surface instead of deep in the pleats, so it pulses clean more completely, holds a lower pressure drop and usually lasts longer, and it filters finer dust (MERV 15). Choose the FR version for metalworking, grinding or anywhere sparks can reach the collector. Many plants pay back the nanofiber premium in fan energy and change-out labor alone.
- How fast do dust collector filters ship?
- In-stock orders placed by noon Central ship the same business day. A few cartridges go UPS Ground; pallet quantities go LTL freight. Both are quoted at checkout before you pay.
- My collector is not listed. Can you still match a filter?
- Usually. Send the part number from the old filter, or its outside diameter, inside diameter, length, end style (open/open or open/closed) and media, through the chat button or the Request a Quote form. We cross-reference against the sizes we stock and tell you what fits before you order.
