Industrial workers often face the challenge of selecting the right filter bag for their application. To simplify this process, we have created a helpful guide to provide information on the important factors to consider when choosing the right filter bag. Our Filter Bag Selection Help Guide provides valuable insight into the five key factors: Fibre Material, Micron Rating, Temperature Range, Chemical Resistance, and Pressure Drop. Through this guide, industrial workers can better understand how to select a filter bag that meets their specific requirements.

Fibre Material

When selecting the right filter bag for a specific application, it’s important to consider the type of fibre material it is made from. Different filter bag fibre materials have different characteristics that make them better suited for certain applications. Common filter bag fibre materials include polyester, polypropylene, and Nomex.

Polyester filter bags offer excellent strength, while polypropylene filter bags are good for applications that require resistance to higher temperatures. Nomex filter bags offer superior chemical resistance and are ideal for applications requiring caustic chemical resistance. Each filter bag fibre material type offers its unique set of benefits and drawbacks, so it’s important to carefully consider which type will be best suited for the job.

Micron Rating

When selecting a filter bag, it is important to consider the micron rating. A micron rating measures the size of particles that the filter bag is designed to capture. The smaller the micron rating, the finer the particles the filter bag can capture. Typical micron ratings range from 0.1 – 200 microns. It is important to select a filter bag with a micron rating that is small enough to capture the particles you need to filter but large enough to prevent excessive pressure drop. If the micron rating is too small, the filter bag will become clogged quickly and require frequent replacement.

Temperature Range

When selecting a filter bag for a particular application, it is essential to consider the range of temperatures the filter bag can handle. Most filter bags are only made to withstand a limited temperature range, typically between -40°F and +120°F. Depending on the application, you may require a filter bag that can withstand a higher temperature range. When considering the temperature range of a filter bag, it is important to factor in the temperatures of the fluid and the environment in which the filter bag is. It is also important to consider the length of time that the filter bag will be exposed to any given temperature. This information can help in selecting the right filter bag for your application.

Chemical Resistance

The chemical resistance of a filter bag is an important factor to consider when selecting the right filter bag for a specific application. Different chemicals have different levels of interaction with filter bags, and it’s important to know how a filter bag will interact with the chemicals it will come into contact with. Some filter bags are generally more chemically resistant than others, with some having a much higher chemical resistance rating than others. It’s important to research a filter bag’s chemical resistance rating before making a final decision. When selecting a filter bag with chemical resistance requirements, it is important to select one highly resistant to the chemicals it will contact.

Pressure Drop

Pressure drop measures the amount of resistance a filter bag has to the flow of air through it. Pressure drop is usually measured in inches of water column (IWC). As the pressure drop increases, the flow of air decreases, thus making it harder for the filter bag to remove particles from the air. When selecting a filter bag, it is important to ensure the pressure drop rating is adequate for the particular application. If the pressure drop is too low, it could result in inadequate filtration. If the pressure drop is too high, it could lead to excess energy consumption. It is important to choose a filter bag with the right pressure drop rating to ensure the efficiency and effectiveness of the filtration process.


Choosing the right filter bag for an industrial application can be daunting. With the help of our Filter Bag Selection Help Guide, it is easier to understand the five key factors to consider when selecting the right filter bag: fibre material, micron rating, temperature range, chemical resistance, and pressure drop.

We hope this guide has helped you better recognize the important factors to consider when selecting the most suitable filter bag for your specific application. As a reminder, our Filter Bag Selection Help Guide is a useful resource that can help you answer all your questions and make selecting the right filter bag easier.
