How to Choose

How to Choose the Right Filter Media

Dust collector filter media does the real work in any dust collection system. The fabric captures dust particles and particulate matter on its surface, builds a dust cake that raises filtration efficiency, and then has to release that cake every time the cleaning system pulses or shakes. The right media balances airflow, pressure drop, dust release, temperature limits and chemical resistance, and that balance sets filter life, dust holding capacity and overall collector performance.

Start with your operating temperature and the chemistry of the air stream, then look at the dust itself: fine, sticky, combustible or moist dust and highly abrasive dust each point to a different fiber, weight and finish. Finally, match the air permeability and dust load to your industrial dust collector and its air-to-cloth ratio. Our air-to-cloth calculator helps you size it, and our guide to fabric filter media for industrial dust collection goes deeper.

Warning Signs

Signs You Need a Different Media

  • High differential pressure that filter cleaning will not bring down

  • Dust bleeding through or visible stack emissions

  • Filter bags blinding with fine, sticky or damp dust

  • Brittle, shrunken or discolored bags from heat or chemicals

  • Holes and wear from abrasive dust

Air Permeability

Filter Media Air Permeability Chart

Typical air permeability ranges, in CFM, for the needle felts, woven filter fabrics and coated materials we use. Lower CFM means a tighter fabric capturing fine particles for higher filter efficiency; higher CFM passes more air at a lower pressure drop. “Call” means data is available on request, and 0 marks a coated or rubber fabric that does not pass air.

Needle Felts

Needle Felt Filter Fabrics

Needle felt is the most common filtration media for pulse-jet baghouses and heavy-duty dust collector bags. We stock polyester (PE) felts from 9 oz. to 22 oz. and polypropylene felts in 12 and 16 oz., in plain, singed and glazed finishes on one or both sides, plus shaker felt and Tetratex membrane felt for fine particulate. The right weight and finish extends service life.

Heavier felts are denser with lower air permeability, so they are better at capturing fine dust; singed and glazed surfaces help the collected dust release so you can clean the filters with less compressed air. Felts are sewn into our replacement filter bags and baghouse replacement filters.

Woven Fabrics

Woven Filter Fabrics

Woven filter fabrics release dust easily and hold their shape, which makes them a good fit for shaker and reverse-air dust collectors, collection bags and covers. We work with cotton and polyester sateen, canton flannel from 8 to 14 oz., Dacron, polyester, nylon satin, and nylon, polyester and cotton duck.

Tightly woven fabrics such as Victor nylon, nylon duck and Cordura have very low air permeability for dust containment, while open weaves such as 322 polyester move more air. See our collection bags made from these fabrics.

Specialty & Coated

Specialty, Coated and Screening Media

In addition to common woven and nonwoven textiles, we stock vinyl and rubber coated fabrics such as Hypalon and CL black and white rubber, and synthetic and stainless steel screening materials. Coated fabrics do not pass air, so they are used for connectors, covers and rubber and fabric connections.

We also work with an extensive range of special order material options for applications needing high temperature, chemical resistance, extra strength or air permeability, including Nomex® aramid for hot gas streams. Many of these fabrics are, or can be treated to, shed sticky dust, bleed static electricity and resist burning, and treated polyester media can improve ease of maintenance in sticky dust applications. Ask about screening media too.

Bag vs Cartridge

Cartridge vs Bag Filter Media

Most industrial dust collectors use either cartridge or bag filters, and each filter type uses a different media. Felt and woven bag media handle heavy, abrasive and hot dust; pleated cartridge media offers high filtration efficiency on fine, dry dust with a smaller footprint. Polyester filter media in either form gives efficient dust capture for most industrial processes; the right choice depends on your specific application.

We supply both. See our replacement dust collector cartridge filters for pleated media, or ask which media is best for your application.

Factor Bag vs Cartridge Filter Media
Media Bags use needle felt or woven fabric; filter cartridges use pleated media such as spunbond polyester, cellulose blends or nanofiber-coated media
Dust load Bags handle heavy dust load and high-volume dust applications; cartridges suit light to moderate, dry dust
Temperature Bags are available in high-temperature fibers; standard filter cartridges run cooler
Cleaning Bags clean by pulse-jet, shaker or reverse air; cartridges clean by compressed air pulse
Footprint The pleated design packs more surface area into a compact collector design, so you need fewer filter elements

FAQs

Filter Fabric Questions

Have a sample, a spec sheet or a dust problem you cannot solve? Our team can help choose the media.

Filter media is the fabric or material that actually captures dust and particulate in a filter. In a baghouse, the media is usually a needle felt or woven fabric sewn into bags, while a dust collector cartridge filter uses pleated media. The right choice depends on your dust, temperature, moisture and chemistry.

Needle felt is a nonwoven fabric made by needling fibers into a dense, three-dimensional mat. It captures fine dust deep in the fabric and is the standard media for pulse-jet baghouses. Woven filter fabrics such as sateen, canton flannel and duck cloth have an open weave and release dust easily, which suits shaker collectors.

Air permeability is how much air passes through a square foot of fabric at a set pressure drop, measured in cubic feet per minute. A lower CFM fabric is tighter and captures finer dust, while a higher CFM fabric moves more air with less resistance. Our air permeability chart lists typical ranges for each fabric we use.

Singeing passes the felt surface over a flame to remove loose fibers so dust releases more easily. Glazing presses the surface smooth with heat for even better dust cake release on sticky or fine dust. Both finishes can be on one side or both sides of the felt.

Polyester (Dacron) is rated to about 275° F continuous, and aramid fibers such as Nomex® handle about 428° F continuous. Polypropylene and cotton are limited to lower temperatures. Our fiber reference chart compares heat, acid, alkali, abrasion and UV resistance.

Yes. Many fabrics are, or can be treated to, shed sticky dust, bleed static electricity and resist burning. Tell us about your dust and process and we will recommend a fabric and finish.

A burn test is a quick way to identify the fiber. Burn a small sample safely and compare how it burns, its odor and its ash to our fabric burn test chart, or send us a sample and we will identify it and match it for your replacement filters.
