Industrial dust collection systems play a crucial role in protecting both employees and equipment by removing harmful particulates from the air. A key component of these systems is the cartridge filter, which traps dust and debris so that clean air is recirculated back into your facility. Here at A.C.T. Dust Collectors, we’ve spent years perfecting solutions for a wide range of industries, and our expertise underscores how choosing the right filter can make a major difference in safety, maintenance needs, and overall productivity.
Different filter media types exist to meet the unique demands of specific applications. Temperature ranges, types of particulates, and process conditions all factor into what filter will work best. Next, we’ll walk you through the most common cartridge filters used in industrial dust collectors, explaining how each one functions and where it excels. By understanding these filter options, you’ll be better equipped to select a solution that keeps your workplace safe and compliant while minimizing downtime and costs.
Cartridge filters do more than just capture dust, as they’re also integral to system longevity, regulatory compliance, and overall worker well-being. When filters match the demands of your process, they trap hazardous particulates efficiently, preventing them from re-entering the facility’s air supply. This not only protects employees from airborne irritants or toxins but also keeps machinery cleaner, extending the lifespan of your dust collection system. This is crucial in multiple industries, ranging from woodworking to metalworking.
However, using the wrong filter media can lead to clogs, higher pressure drop, and more frequent filter replacements. Overloaded or underperforming filters can force your cartridge dust collection unit to work harder, resulting in increased energy consumption and unnecessary operational costs. In severe cases, inadequate filtration might put workers at risk of breathing harmful dust or failing to meet industry safety standards.
That’s why selecting the correct cartridge filter media for your custom dust collection system is a critical decision. Factors like dust type, particle size, humidity, and operating temperature all influence filter performance. A mismatch between filter media and application can derail your entire dust management strategy, but with the right guidance, you can avoid these pain points and maintain a safe, efficient working environment.
When it comes to industrial dust collector cartridge filters, certain types dominate the market due to their versatility and cost-effectiveness. For instance, cellulose filters (often treated with flame-retardant coatings) are popular for general applications, offering good filtration at a relatively low cost. However, their performance may decline in high-humidity environments or where extremely fine particulates are present.
Another commonly used option is a synthetic-blend filter media, which combines synthetic fibers with cellulose for enhanced durability and higher filtration efficiency. These filters tend to handle fine dust better than standard cellulose filters and can often withstand slightly higher temperatures. While they’re a bit more expensive, they deliver improved performance and a longer service life in challenging conditions.
Although we do sell this filter, it is not what we supply as a “standard” in our systems (we’ll tell you why in just a minute). This is the most common and economical cartridge industrial dust collection filter media on the market. Comprised of 80% polyester and 20% cellulose and available in standard and flame-retardant versions, 80/20 filters are cost-effective but generally less effective in performance.
These are different from flame-proof filters. Selecting a flame-retardant version of the 80/20 means you are working in applications that use hot embers and produce sparks, like grinding, laser cutting, or welding.
Typically, a standard 80/20 filter can be used in a variety of applications – but here’s why we use the following cartridge industrial dust collector filter instead.
Nanofiber cartridge filters are the most efficient version of a standard industrial dust collector filter. These can be used for most applications and also come in a standard or flame-retardant form. The actual nanofiber webbing laid on top of the filter media is what prevents particulates from getting embedded, allowing it to have a better release property and, therefore, making it easier for the pulse cleaning system to clean. These filters are the standard filters for our A.C.T. cartridge units because they run smoothly across many applications.
With an 80/20 filter, there is a higher chance of bypassing without the additional webbing. Nanofiber filters also carry a MERV 15 efficiency rating, which is the best in the industry, and account for up to 254 square feet of particulate per filter. In fact, the finer the particulate, the more efficient a nanofiber cartridge filter will be. Nanofiber filters are also versatile in that they fit into other non-A.C.T. Dust Collector systems.
After nanofiber filters, spun-bond polyester filters are the next most commonly used cartridge filters. These filters are made by bonding together extruded spun filaments of polyester to create a durable, thick, and heavy web of material.
Because of their structure, spun-bound polyester cartridge filters deal with heavy-loading applications better than other filters but only have up to 100-120 square feet of filter media per filter. At a MERV 10 rating, they also do not perform as efficiently as nanofiber filters. However, these filters have great release properties and can capture larger particulates typically created by food processing applications.
Sometimes, standard filters don’t meet all environmental or operational needs. That’s where specialized cartridge industrial dust collection filters come into play. For instance, PTFE with Nomex® technology is highly sought after for high-temperature applications—typically over 180 degrees—and offers exceptional filtration efficiency. While the cost is significantly higher, these filters excel in industries such as drying operations, foundries, and metal melting facilities where extreme heat and performance demands justify the investment.
HEPA filters are another niche solution, although they’re generally used as secondary or “safety” filters rather than primary cartridges. Mandated by OSHA for certain hazardous processes, HEPA filters capture extremely fine particulates that might slip through the primary filter if it becomes compromised. This secondary layer of protection is especially important in processes involving toxic dust or volatile materials, ensuring no harmful particulates escape into the facility.
In addition, hydro-oleophobic filters are designed to repel moisture and oily substances, preventing them from clogging the filter media. They’re especially valuable in settings where liquids or oils frequently mix with dust, potentially reducing airflow and shortening filter life. By repelling these substances, hydro-oleophobic filters maintain better efficiency over time, which can translate to lower operational costs in the long run.
Selecting the best filter type starts with understanding your application’s specific requirements—such as dust composition, temperature ranges, and moisture levels. You’ll also need to consider how frequently filters must be changed, along with any industry regulations governing emissions or air quality.
